Chapter 1 - Heritable Material Vocabulary

Like my friend Kylie read this to me "**Civil Disobedience** By Henry David Thoreau 1849 I heartily accept the motto, "That government is best which governs least"; and I should like to see it acted up to more rapidly and systematically. Carried out, it finally amounts to this, which also I believe- "That government is best which governs not at all"; and when men are prepared for it, that will be the kind of government which they will have. Government is at best but an expedient; but most governments are usually, and all governments are sometimes, inexpedient. The objections which have been brought against a standing army, and they are many and weighty, and deserve to prevail, may also at last be brought against a standing government. The standing army is only an arm of the standing government. The government itself, which is only the mode which the people have chosen to execute their will, is equally liable to be abused and perverted before the people can act through it. Witness the present Mexican war, the work of comparatively a few individuals using the standing government as their tool; for, in the outset, the people would not have consented to this measure. This American government- what is it but a tradition, though a recent one, endeavoring to transmit itself unimpaired to posterity, but each instant losing some of its integrity? It has not the vitality and force of a single living man; for a single man can bend it to his will. It is a sort of wooden gun to the people themselves. But it is not the less necessary for this; for the people must have some complicated machinery or other, and hear its din, to satisfy that idea of government which they have. Governments show thus how successfully men can be imposed on, even impose on themselves, for their own advantage. It is excellent, we must all allow. Yet this government never of itself furthered any enterprise, but by the alacrity with which it got out of its way. It does not keep the country free. It does not settle the West. It does not educate. The character inherent in the American people has done all that has been accomplished; and it would have done somewhat more, if the government had not sometimes got in its way. For government is an expedient by which men would fain succeed in letting one another alone; and, as has been said, when it is most expedient, the governed are most let alone by it. Trade and commerce, if they were not made of india-rubber, would never manage to bounce over the obstacles which legislators are continually putting in their way; and, if one were to judge these men wholly by the effects of their actions and not partly by their intentions, they would deserve to be classed and punished with those mischievous persons who put obstructions on the railroads. But, to speak practically and as a citizen, unlike those who call themselves no- government men, I ask for, not at once no government, but at once a better government. Let every man make known what kind of government would command his respect, and that will be one step toward obtaining it. After all, the practical reason why, when the power is once in the hands of the people, a majority are permitted, and for a long period continue, to rule is not because they are most likely to be in the right, nor because this seems fairest to the minority, but because they are physically the strongest. But a government in which the majority rule in all cases cannot be based on justice, even as far as men understand it. Can there not be a government in which majorities do not virtually decide right and wrong, but conscience?- in which majorities decide only those questions to which the rule of expediency is applicable? Must the citizen ever for a moment, or in the least degree, resign his conscience to the legislation? Why has every man a conscience, then? I think that we should be men first, and subjects afterward. It is not desirable to cultivate a respect for the law, so much as for the right. The only obligation which I have a right to assume is to do at any time what I think right. It is truly enough said that a corporation has no conscience; but a corporation of conscientious men is a corporation with a conscience. Law never made men a whit more just; and, by means of their respect for it, even the well-disposed are daily made the agents of injustice. A common and natural result of an undue respect for law is, that you may see a file of soldiers, colonel, captain, corporal, privates, powder- monkeys, and all, marching in admirable order over hill and dale to the wars, against their wills, ay, against their common sense and consciences, which makes it very steep marching indeed, and produces a palpitation of the heart. They have no doubt that it is a damnable business in which they are concerned; they are all peaceably inclined. Now, what are they? Men at all? or small movable forts and magazines, at the service of some unscrupulous man in power? Visit the Navy-Yard, and behold a marine, such a man as an American government can make, or such as it can make a man with its black arts- a mere shadow and reminiscence of humanity, a man laid out alive and standing, and already, as one may say, buried under arms with funeral accompaniments, though it may be, "Not a drum was heard, not a funeral note, As his corse to the rampart we hurried; Not a soldier discharged his farewell shot O'er the grave where our hero we buried." The mass of men serve the state thus, not as men mainly, but as machines, with their bodies. They are the standing army, and the militia, jailers, constables, posse comitatus, etc. In most cases there is no free exercise whatever of the judgment or of the moral sense; but they put themselves on a level with wood and earth and stones; and wooden men can perhaps be manufactured that will serve the purpose as well. Such command no more respect than men of straw or a lump of dirt. They have the same sort of worth only as horses and dogs. Yet such as these even are commonly esteemed good citizens. Others- as most legislators, politicians, lawyers, ministers, and office-holders- serve the state chiefly with their heads; and, as they rarely make any moral distinctions, they are as likely to serve the devil, without intending it, as God. A very few- as heroes, patriots, martyrs, reformers in the great sense, and men- serve the state with their consciences also, and so necessarily resist it for the most part; and they are commonly treated as enemies by it. A wise man will only be useful as a man, and will not submit to be "clay," and "stop a hole to keep the wind away," but leave that office to his dust at least: "I am too high-born to be propertied, To be a secondary at control, Or useful serving-man and instrument To any sovereign state throughout the world." He who gives himself entirely to his fellow-men appears to them useless and selfish; but he who gives himself partially to them is pronounced a benefactor and philanthropist. How does it become a man to behave toward this American government today? I answer, that he cannot without disgrace be associated with it. I cannot for an instant recognize that political organization as my government which is the slave's government also. All men recognize the right of revolution; that is, the right to refuse allegiance to, and to resist, the government, when its tyranny or its inefficiency are great and unendurable. But almost all say that such is not the case now. But such was the case, they think, in the Revolution Of '75. If one were to tell me that this was a bad government because it taxed certain foreign commodities brought to its ports, it is most probable that I should not make an ado about it, for I can do without them. All machines have their friction; and possibly this does enough good to counterbalance the evil. At any rate, it is a great evil to make a stir about it. But when the friction comes to have its machine, and oppression and robbery are organized, I say, let us not have such a machine any longer. In other words, when a sixth of the population of a nation which has undertaken to be the refuge of liberty are slaves, and a whole country is unjustly overrun and conquered by a foreign army, and subjected to military law, I think that it is not too soon for honest men to rebel and revolutionize. What makes this duty the more urgent is the fact that the country so overrun is not our own, but ours is the invading army. Paley, a common authority with many on moral questions, in his chapter on the "Duty of Submission to Civil Government," resolves all civil obligation into expediency; and he proceeds to say that "so long as the interest of the whole society requires it, that is, so long as the established government cannot be resisted or changed without public inconveniency, it is the will of God... that the established government be obeyed- and no longer. This principle being admitted, the justice of every particular case of resistance is reduced to a computation of the quantity of the danger and grievance on the one side, and of the probability and expense of redressing it on the other." Of this, he says, every man shall judge for himself. But Paley appears never to have contemplated those cases to which the rule of expediency does not apply, in which a people, as well as an individual, must do justice, cost what it may. If I have unjustly wrested a plank from a drowning man, I must restore it to him though I drown myself. This, according to Paley, would be inconvenient. But he that would save his life, in such a case, shall lose it. This people must cease to hold slaves, and to make war on Mexico, though it cost them their existence as a people. In their practice, nations agree with Paley; but does any one think that Massachusetts does exactly what is right at the present crisis? "A drab of state, a cloth-o'-silver slut, To have her train borne up, and her soul trail in the dirt." Practically speaking, the opponents to a reform in Massachusetts are not a hundred thousand politicians at the South, but a hundred thousand merchants and farmers here, who are more interested in commerce and agriculture than they are in humanity, and are not prepared to do justice to the slave and to Mexico, cost what it may. I quarrel not with far-off foes, but with those who, near at home, cooperate with, and do the bidding of those far away, and without whom the latter would be harmless. We are accustomed to say, that the mass of men are unprepared; but improvement is slow, because the few are not materially wiser or better than the many. It is not so important that many should be as good as you, as that there be some absolute goodness somewhere; for that will leaven the whole lump. There are thousands who are in opinion opposed to slavery and to the war, who yet in effect do nothing to put an end to them; who, esteeming themselves children of Washington and Franklin, sit down with their hands in their pockets, and say that they know not what to do, and do nothing; who even postpone the question of freedom to the question of free trade, and quietly read the prices-current along with the latest advices from Mexico, after dinner, and, it may be, fall asleep over them both. What is the price-current of an honest man and patriot today? They hesitate, and they regret, and sometimes they petition; but they do nothing in earnest and with effect. They will wait, well disposed, for others to remedy the evil, that they may no longer have it to regret. At most, they give only a cheap vote, and a feeble countenance and God-speed, to the right, as it goes by them. There are nine hundred and ninety-nine patrons of virtue to one virtuous man. But it is easier to deal with the real possessor of a thing than with the temporary guardian of it. All voting is a sort of gaming, like checkers or backgammon, with a slight moral tinge to it, a playing with right and wrong, with moral questions; and betting naturally accompanies it. The character of the voters is not staked. I cast my vote, perchance, as I think right; but I am not vitally concerned that that right should prevail. I am willing to leave it to the majority. Its obligation, therefore, never exceeds that of expediency. Even voting for the right is doing nothing for it. It is only expressing to men feebly your desire that it should prevail. A wise man will not leave the right to the mercy of chance, nor wish it to prevail through the power of the majority. There is but little virtue in the action of masses of men. When the majority shall at length vote for the abolition of slavery, it will be because they are indifferent to slavery, or because there is but little slavery left to be abolished by their vote. They will then be the only slaves. Only his vote can hasten the abolition of slavery who asserts his own freedom by his vote. I hear of a convention to be held at Baltimore, or elsewhere, for the selection of a candidate for the Presidency, made up chiefly of editors, and men who are politicians by profession; but I think, what is it to any independent, intelligent, and respectable man what decision they may come to? Shall we not have the advantage of his wisdom and honesty, nevertheless? Can we not count upon some independent votes? Are there not many individuals in the country who do not attend conventions? But no: I find that the respectable man, so called, has immediately drifted from his position, and despairs of his country, when his country has more reason to despair of him. He forthwith adopts one of the candidates thus selected as the only available one, thus proving that he is himself available for any purposes of the demagogue. His vote is of no more worth than that of any unprincipled foreigner or hireling native, who may have been bought. O for a man who is a man, and, as my neighbor says, has a bone in his back which you cannot pass your hand through! Our statistics are at fault: the population has been returned too large. How many men are there to a square thousand miles in this country? Hardly one. Does not America offer any inducement for men to settle here? The American has dwindled into an Odd Fellow-one who may be known by the development of his organ of gregariousness, and a manifest lack of intellect and cheerful self-reliance; whose first and chief concern, on coming into the world, is to see that the almshouses are in good repair; and, before yet he has lawfully donned the virile garb, to collect a fund for the support of the widows and orphans that may be; who, in short, ventures to live only by the aid of the Mutual Insurance company, which has promised to bury him decently. It is not a man's duty, as a matter of course, to devote himself to the eradication of any, even the most enormous, wrong; he may still properly have other concerns to engage him; but it is his duty, at least, to wash his hands of it, and, if he gives it no thought longer, not to give it practically his support. If I devote myself to other pursuits and contemplations, I must first see, at least, that I do not pursue them sitting upon another man's shoulders. I must get off him first, that he may pursue his contemplations too. See what gross inconsistency is tolerated. I have heard some of my townsmen say, "I should like to have them order me out to help put down an insurrection of the slaves, or to march to Mexico;- see if I would go"; and yet these very men have each, directly by their allegiance, and so indirectly, at least, by their money, furnished a substitute. The soldier is applauded who refuses to serve in an unjust war by those who do not refuse to sustain the unjust government which makes the war; is applauded by those whose own act and authority he disregards and sets at naught; as if the state were penitent to that degree that it differed one to scourge it while it sinned, but not to that degree that it left off sinning for a moment. Thus, under the name of Order and Civil Government, we are all made at last to pay homage to and support our own meanness. After the first blush of sin comes its indifference; and from immoral it becomes, as it were, unmoral, and not quite unnecessary to that life which we have made. The broadest and most prevalent error requires the most disinterested virtue to sustain it. The slight reproach to which the virtue of patriotism is commonly liable, the noble are most likely to incur. Those who, while they disapprove of the character and measures of a government, yield to it their allegiance and support are undoubtedly its most conscientious supporters, and so frequently the most serious obstacles to reform. Some are petitioning the State to dissolve the Union, to disregard the requisitions of the President. Why do they not dissolve it themselves- the union between themselves and the State- and refuse to pay their quota into its treasury? Do not they stand in the same relation to the State that the State does to the Union? And have not the same reasons prevented the State from resisting the Union which have prevented them from resisting the State? How can a man be satisfied to entertain an opinion merely, and enjoy it? Is there any enjoyment in it, if his opinion is that he is aggrieved? If you are cheated out of a single dollar by your neighbor, you do not rest satisfied with knowing that you are cheated, or with saying that you are cheated, or even with petitioning him to pay you your due; but you take effectual steps at once to obtain the full amount, and see that you are never cheated again. Action from principle, the perception and the performance of right, changes things and relations; it is essentially revolutionary, and does not consist wholly with anything which was. It not only divides States and churches, it divides families; ay, it divides the individual, separating the diabolical in him from the divine. Unjust laws exist: shall we be content to obey them, or shall we endeavor to amend them, and obey them until we have succeeded, or shall we transgress them at once? Men generally, under such a government as this, think that they ought to wait until they have persuaded the majority to alter them. They think that, if they should resist, the remedy would be worse than the evil. But it is the fault of the government itself that the remedy is worse than the evil. It makes it worse. Why is it not more apt to anticipate and provide for reform? Why does it not cherish its wise minority? Why does it cry and resist before it is hurt? Why does it not encourage its citizens to be on the alert to point out its faults, and do better than it would have them? Why does it always crucify Christ, and excommunicate Copernicus and Luther, and pronounce Washington and Franklin rebels? One would think, that a deliberate and practical denial of its authority was the only offence never contemplated by government; else, why has it not assigned its definite, its suitable and proportionate, penalty? If a man who has no property refuses but once to earn nine shillings for the State, he is put in prison for a period unlimited by any law that I know, and determined only by the discretion of those who placed him there; but if he should steal ninety times nine shillings from the State, he is soon permitted to go at large again. If the injustice is part of the necessary friction of the machine of government, let it go, let it go: perchance it will wear smooth- certainly the machine will wear out. If the injustice has a spring, or a pulley, or a rope, or a crank, exclusively for itself, then perhaps you may consider whether the remedy will not be worse than the evil; but if it is of such a nature that it requires you to be the agent of injustice to another, then, I say, break the law. Let your life be a counter-friction to stop the machine. What I have to do is to see, at any rate, that I do not lend myself to the wrong which I condemn. As for adopting the ways which the State has provided for remedying the evil, I know not of such ways. They take too much time, and a man's life will be gone. I have other affairs to attend to. I came into this world, not chiefly to make this a good place to live in, but to live in it, be it good or bad. A man has not everything to do, but something; and because he cannot do everything, it is not necessary that he should do something wrong. It is not my business to be petitioning the Governor or the Legislature any more than it is theirs to petition me; and if they should not bear my petition, what should I do then? But in this case the State has provided no way: its very Constitution is the evil. This may seem to be harsh and stubborn and unconciliatory; but it is to treat with the utmost kindness and consideration the only spirit that can appreciate or deserves it. So is an change for the better, like birth and death, which convulse the body. I do not hesitate to say, that those who call themselves Abolitionists should at once effectually withdraw their support, both in person and property, from the government of Massachusetts, and not wait till they constitute a majority of one, before they suffer the right to prevail through them. I think that it is enough if they have God on their side, without waiting for that other one. Moreover, any man more right than his neighbors constitutes a majority of one already. I meet this American government, or its representative, the State government, directly, and face to face, once a year- no more- in the person of its tax- gatherer; this is the only mode in which a man situated as I am necessarily meets it; and it then says distinctly, Recognize me; and the simplest, the most effectual, and, in the present posture of affairs, the indispensablest mode of treating with it on this head, of expressing your little satisfaction with and love for it, is to deny it then. My civil neighbor, the tax-gatherer, is the very man I have to deal with- for it is, after all, with men and not with parchment that I quarrel- and he has voluntarily chosen to be an agent of the government. How shall he ever know well what he is and does as an officer of the government, or as a man, until he is obliged to consider whether he shall treat me, his neighbor, for whom he has respect, as a neighbor and well-disposed man, or as a maniac and disturber of the peace, and see if he can get over this obstruction to his neighborliness without a ruder and more impetuous thought or speech corresponding with his action. I know this well, that if one thousand, if one hundred, if ten men whom I could name- if ten honest men only- ay, if one HONEST man, in this State of Massachusetts, ceasing to hold slaves, were actually to withdraw from this copartnership, and be locked up in the county jail therefor, it would be the abolition of slavery in America. For it matters not how small the beginning may seem to be: what is once well done is done forever. But we love better to talk about it: that we say is our mission, Reform keeps many scores of newspapers in its service, but not one man. If my esteemed neighbor, the State's ambassador, who will devote his days to the settlement of the question of human rights in the Council Chamber, instead of being threatened with the prisons of Carolina, were to sit down the prisoner of Massachusetts, that State which is so anxious to foist the sin of slavery upon her sister- though at present she can discover only an act of inhospitality to be the ground of a quarrel with her- the Legislature would not wholly waive the subject the following winter. Under a government which imprisons any unjustly, the true place for a just man is also a prison. The proper place today, the only place which Massachusetts has provided for her freer and less desponding spirits, is in her prisons, to be put out and locked out of the State by her own act, as they have already put themselves out by their principles. It is there that the fugitive slave, and the Mexican prisoner on parole, and the Indian come to plead the wrongs of his race should find them; on that separate, but more free and honorable, ground, where the State places those who are not with her, but against her- the only house in a slave State in which a free man can abide with honor. If any think that their influence would be lost there, and their voices no longer afflict the ear of the State, that they would not be as an enemy within its walls, they do not know by how much truth is stronger than error, nor how much more eloquently and effectively he can combat injustice who has experienced a little in his own person. Cast your whole vote, not a strip of paper merely, but your whole influence. A minority is powerless while it conforms to the majority; it is not even a minority then; but it is irresistible when it clogs by its whole weight. If the alternative is to keep all just men in prison, or give up war and slavery, the State will not hesitate which to choose. If a thousand men were not to pay their tax-bills this year, that would not be a violent and bloody measure, as it would be to pay them, and enable the State to commit violence and shed innocent blood. This is, in fact, the definition of a peaceable revolution, if any such is possible. If the tax-gatherer, or any other public officer, asks me, as one has done, "But what shall I do?" my answer is, "If you really wish to do anything, resign your office." When the subject has refused allegiance, and the officer has resigned his office, then the revolution is accomplished. But even suppose blood should flow. Is there not a sort of blood shed when the conscience is wounded? Through this wound a man's real manhood and immortality flow out, and he bleeds to an everlasting death. I see this blood flowing now. I have contemplated the imprisonment of the offender, rather than the seizure of his goods- though both will serve the same purpose- because they who assert the purest right, and consequently are most dangerous to a corrupt State, commonly have not spent much time in accumulating property. To such the State renders comparatively small service, and a slight tax is wont to appear exorbitant, particularly if they are obliged to earn it by special labor with their hands. If there were one who lived wholly without the use of money, the State itself would hesitate to demand it of him. But the rich man- not to make any invidious comparison- is always sold to the institution which makes him rich. Absolutely speaking, the more money, the less virtue; for money comes between a man and his objects, and obtains them for him; and it was certainly no great virtue to obtain it. It puts to rest many questions which he would otherwise be taxed to answer; while the only new question which it puts is the hard but superfluous one, how to spend it. Thus his moral ground is taken from under his feet. The opportunities of living are diminished in proportion as what are called the "means" are increased. The best thing a man can do for his culture when he is rich is to endeavor to carry out those schemes which he entertained when he was poor. Christ answered the Herodians according to their condition. "Show me the tribute-money," said he;- and one took a penny out of his pocket;- if you use money which has the image of Caesar on it, and which he has made current and valuable, that is, if you are men of the State, and gladly enjoy the advantages of Caesar's government, then pay him back some of his own when he demands it. "Render therefore to Caesar that which is Caesar's, and to God those things which are God's"- leaving them no wiser than before as to which was which; for they did not wish to know. When I converse with the freest of my neighbors, I perceive that, whatever they may say about the magnitude and seriousness of the question, and their regard for the public tranquillity, the long and the short of the matter is, that they cannot spare the protection of the existing government, and they dread the consequences to their property and families of disobedience to it. For my own part, I should not like to think that I ever rely on the protection of the State. But, if I deny the authority of the State when it presents its tax-bill, it will soon take and waste all my property, and so harass me and my children without end. This is hard. This makes it impossible for a man to live honestly, and at the same time comfortably, in outward respects. It will not be worth the while to accumulate property; that would be sure to go again. You must hire or squat somewhere, and raise but a small crop, and eat that soon. You must live within yourself, and depend upon yourself always tucked up and ready for a start, and not have many affairs. A man may grow rich in Turkey even, if he will be in all respects a good subject of the Turkish government. Confucius said: "If a state is governed by the principles of reason, poverty and misery are subjects of shame; if a state is not governed by the principles of reason, riches and honors are the subjects of shame." No: until I want the protection of Massachusetts to be extended to me in some distant Southern port, where my liberty is endangered, or until I am bent solely on building up an estate at home by peaceful enterprise, I can afford to refuse allegiance to Massachusetts, and her right to my property and life. It costs me less in every sense to incur the penalty of disobedience to the State than it would to obey. I should feel as if I were worth less in that case. Some years ago, the State met me in behalf of the Church, and commanded me to pay a certain sum toward the support of a clergyman whose preaching my father attended, but never I myself. "Pay," it said, "or be locked up in the jail." I declined to pay. But, unfortunately, another man saw fit to pay it. I did not see why the schoolmaster should be taxed to support the priest, and not the priest the schoolmaster; for I was not the State's schoolmaster, but I supported myself by voluntary subscription. I did not see why the lyceum should not present its tax-bill, and have the State to back its demand, as well as the Church. However, at the request of the selectmen, I condescended to make some such statement as this in writing:- "Know all men by these presents, that I, Henry Thoreau, do not wish to be regarded as a member of any incorporated society which I have not joined." This I gave to the town clerk; and he has it. The State, having thus learned that I did not wish to be regarded as a member of that church, has never made a like demand on me since; though it said that it must adhere to its original presumption that time. If I had known how to name them, I should then have signed off in detail from all the societies which I never signed on to; but I did not know where to find a complete list. I have paid no poll-tax for six years. I was put into a jail once on this account, for one night; and, as I stood considering the walls of solid stone, two or three feet thick, the door of wood and iron, a foot thick, and the iron grating which strained the light, I could not help being struck with the foolishness of that institution which treated me as if I were mere flesh and blood and bones, to be locked up. I wondered that it should have concluded at length that this was the best use it could put me to, and had never thought to avail itself of my services in some way. I saw that, if there was a wall of stone between me and my townsmen, there was a still more difficult one to climb or break through before they could get to be as free as I was. I did not for a moment feel confined, and the walls seemed a great waste of stone and mortar. I felt as if I alone of all my townsmen had paid my tax. They plainly did not know how to treat me, but behaved like persons who are underbred. In every threat and in every compliment there was a blunder; for they thought that my chief desire was to stand the other side of that stone wall. I could not but smile to see how industriously they locked the door on my meditations, which followed them out again without let or hindrance, and they were really all that was dangerous. As they could not reach me, they had resolved to punish my body; just as boys, if they cannot come at some person against whom they have a spite, will abuse his dog. I saw that the State was half-witted, that it was timid as a lone woman with her silver spoons, and that it did not know its friends from its foes, and I lost all my remaining respect for it, and pitied it. Thus the State never intentionally confronts a man's sense, intellectual or moral, but only his body, his senses. It is not armed with superior wit or honesty, but with superior physical strength. I was not born to be forced. I will breathe after my own fashion. Let us see who is the strongest. What force has a multitude? They only can force me who obey a higher law than I. They force me to become like themselves. I do not hear of men being forced to have this way or that by masses of men. What sort of life were that to live? When I meet a government which says to me, "Your money or your life," why should I be in haste to give it my money? It may be in a great strait, and not know what to do: I cannot help that. It must help itself; do as I do. It is not worth the while to snivel about it. I am not responsible for the successful working of the machinery of society. I am not the son of the engineer. I perceive that, when an acorn and a chestnut fall side by side, the one does not remain inert to make way for the other, but both obey their own laws, and spring and grow and flourish as best they can, till one, perchance, overshadows and destroys the other. If a plant cannot live according to its nature, it dies; and so a man. The night in prison was novel and interesting enough. The prisoners in their shirt-sleeves were enjoying a chat and the evening air in the doorway, when I entered. But the jailer said, "Come, boys, it is time to lock up"; and so they dispersed, and I heard the sound of their steps returning into the hollow apartments. My room-mate was introduced to me by the jailer as "a first-rate fellow and a clever man." When the door was locked, he showed me where to hang my hat, and how he managed matters there. The rooms were whitewashed once a month; and this one, at least, was the whitest, most simply furnished, and probably the neatest apartment in the town. He naturally wanted to know where I came from, and what brought me there; and, when I had told him, I asked him in my turn how he came there, presuming him to be an honest man, of course; and, as the world goes, I believe he was. "Why," said he, "they accuse me of burning a barn; but I never did it." As near as I could discover, he had probably gone to bed in a barn when drunk, and smoked his pipe there; and so a barn was burnt. He had the reputation of being a clever man, had been there some three months waiting for his trial to come on, and would have to wait as much longer; but he was quite domesticated and contented, since he got his board for nothing, and thought that he was well treated. He occupied one window, and I the other; and I saw that if one stayed there long, his principal business would be to look out the window. I had soon read all the tracts that were left there, and examined where former prisoners had broken out, and where a grate had been sawed off, and heard the history of the various occupants of that room; for I found that even here there was a history and a gossip which never circulated beyond the walls of the jail. Probably this is the only house in the town where verses are composed, which are afterward printed in a circular form, but not published. I was shown quite a long list of verses which were composed by some young men who had been detected in an attempt to escape, who avenged themselves by singing them. I pumped my fellow-prisoner as dry as I could, for fear I should never see him again; but at length he showed me which was my bed, and left me to blow out the lamp. It was like travelling into a far country, such as I had never expected to behold, to lie there for one night. It seemed to me that I never had heard the town clock strike before, nor the evening sounds of the village; for we slept with the windows open, which were inside the grating. It was to see my native village in the light of the Middle Ages, and our Concord was turned into a Rhine stream, and visions of knights and castles passed before me. They were the voices of old burghers that I heard in the streets. I was an involuntary spectator and auditor of whatever was done and said in the kitchen of the adjacent village inn- a wholly new and rare experience to me. It was a closer view of my native town. I was fairly inside of it. I never had seen its institutions before. This is one of its peculiar institutions; for it is a shire town. I began to comprehend what its inhabitants were about. In the morning, our breakfasts were put through the hole in the door, in small oblong-square tin pans, made to fit, and holding a pint of chocolate, with brown bread, and an iron spoon. When they called for the vessels again, I was green enough to return what bread I had left; but my comrade seized it, and said that I should lay that up for lunch or dinner. Soon after he was let out to work at haying in a neighboring field, whither he went every day, and would not be back till noon; so he bade me good-day, saying that he doubted if he should see me again. When I came out of prison- for some one interfered, and paid that tax- I did not perceive that great changes had taken place on the common, such as he observed who went in a youth and emerged a tottering and gray-headed man; and yet a change had to my eyes come over the scene- the town, and State, and country- greater than any that mere time could effect. I saw yet more distinctly the State in which I lived. I saw to what extent the people among whom I lived could be trusted as good neighbors and friends; that their friendship was for summer weather only; that they did not greatly propose to do right; that they were a distinct race from me by their prejudices and superstitions, as the Chinamen and Malays are; that in their sacrifices to humanity they ran no risks, not even to their property; that after all they were not so noble but they treated the thief as he had treated them, and hoped, by a certain outward observance and a few prayers, and by walking in a particular straight though useless path from time to time, to save their souls. This may be to judge my neighbors harshly; for I believe that many of them are not aware that they have such an institution as the jail in their village. It was formerly the custom in our village, when a poor debtor came out of jail, for his acquaintances to salute him, looking through their fingers, which were crossed to represent the grating of a jail window, "How do ye do?" My neighbors did not thus salute me, but first looked at me, and then at one another, as if I had returned from a long journey. I was put into jail as I was going to the shoemaker's to get a shoe which was mended. When I was let out the next morning, I proceeded to finish my errand, and, having put on my mended shoe, joined a huckleberry party, who were impatient to put themselves under my conduct; and in half an hour- for the horse was soon tackled- was in the midst of a huckleberry field, on one of our highest hills, two miles off, and then the State was nowhere to be seen. This is the whole history of "My Prisons." I have never declined paying the highway tax, because I am as desirous of being a good neighbor as I am of being a bad subject; and as for supporting schools, I am doing my part to educate my fellow-countrymen now. It is for no particular item in the tax-bill that I refuse to pay it. I simply wish to refuse allegiance to the State, to withdraw and stand aloof from it effectually. I do not care to trace the course of my dollar, if I could, till it buys a man or a musket to shoot one with- the dollar is innocent- but I am concerned to trace the effects of my allegiance. In fact, I quietly declare war with the State, after my fashion, though I will still make what use and get what advantage of her I can, as is usual in such cases. If others pay the tax which is demanded of me, from a sympathy with the State, they do but what they have already done in their own case, or rather they abet injustice to a greater extent than the State requires. If they pay the tax from a mistaken interest in the individual taxed, to save his property, or prevent his going to jail, it is because they have not considered wisely how far they let their private feelings interfere with the public good. This, then, is my position at present. But one cannot be too much on his guard in such a case, lest his action be biased by obstinacy or an undue regard for the opinions of men. Let him see that he does only what belongs to himself and to the hour. I think sometimes, Why, this people mean well, they are only ignorant; they would do better if they knew how: why give your neighbors this pain to treat you as they are not inclined to? But I think again, This is no reason why I should do as they do, or permit others to suffer much greater pain of a different kind. Again, I sometimes say to myself, When many millions of men, without heat, without ill will, without personal feeling of any kind, demand of you a few shillings only, without the possibility, such is their constitution, of retracting or altering their present demand, and without the possibility, on your side, of appeal to any other millions, why expose yourself to this overwhelming brute force? You do not resist cold and hunger, the winds and the waves, thus obstinately; you quietly submit to a thousand similar necessities. You do not put your head into the fire. But just in proportion as I regard this as not wholly a brute force, but partly a human force, and consider that I have relations to those millions as to so many millions of men, and not of mere brute or inanimate things, I see that appeal is possible, first and instantaneously, from them to the Maker of them, and, secondly, from them to themselves. But if I put my head deliberately into the fire, there is no appeal to fire or to the Maker of fire, and I have only myself to blame. If I could convince myself that I have any right to be satisfied with men as they are, and to treat them accordingly, and not according, in some respects, to my requisitions and expectations of what they and I ought to be, then, like a good Mussulman and fatalist, I should endeavor to be satisfied with things as they are, and say it is the will of God. And, above all, there is this difference between resisting this and a purely brute or natural force, that I can resist this with some effect; but I cannot expect, like Orpheus, to change the nature of the rocks and trees and beasts. I do not wish to quarrel with any man or nation. I do not wish to split hairs, to make fine distinctions, or set myself up as better than my neighbors. I seek rather, I may say, even an excuse for conforming to the laws of the land. I am but too ready to conform to them. Indeed, I have reason to suspect myself on this head; and each year, as the tax-gatherer comes round, I find myself disposed to review the acts and position of the general and State governments, and the spirit of the people, to discover a pretext for conformity. "We must affect our country as our parents, And if at any time we alienate Our love or industry from doing it honor, We must respect effects and teach the soul Matter of conscience and religion, And not desire of rule or benefit." I believe that the State will soon be able to take all my work of this sort out of my hands, and then I shall be no better a patriot than my fellow-countrymen. Seen from a lower point of view, the Constitution, with all its faults, is very good; the law and the courts are very respectable; even this State and this American government are, in many respects, very admirable, and rare things, to be thankful for, such as a great many have described them; but seen from a point of view a little higher, they are what I have described them; seen from a higher still, and the highest, who shall say what they are, or that they are worth looking at or thinking of at all? However, the government does not concern me much, and I shall bestow the fewest possible thoughts on it. It is not many moments that I live under a government, even in this world. If a man is thought-free, fancy-free, imagination-free, that which is not never for a long time appearing to be to him, unwise rulers or reformers cannot fatally interrupt him. I know that most men think differently from myself; but those whose lives are by profession devoted to the study of these or kindred subjects content me as little as any. Statesmen and legislators, standing so completely within the institution, never distinctly and nakedly behold it. They speak of moving society, but have no resting-place without it. They may be men of a certain experience and discrimination, and have no doubt invented ingenious and even useful systems, for which we sincerely thank them; but all their wit and usefulness lie within certain not very wide limits. They are wont to forget that the world is not governed by policy and expediency. Webster never goes behind government, and so cannot speak with authority about it. His words are wisdom to those legislators who contemplate no essential reform in the existing government; but for thinkers, and those who legislate for all time, he never once glances at the subject. I know of those whose serene and wise speculations on this theme would soon reveal the limits of his mind's range and hospitality. Yet, compared with the cheap professions of most reformers, and the still cheaper wisdom and eloquence of politicians in general, his are almost the only sensible and valuable words, and we thank Heaven for him. Comparatively, he is always strong, original, and, above all, practical. Still, his quality is not wisdom, but prudence. The lawyer's truth is not Truth, but consistency or a consistent expediency. Truth is always in harmony with herself, and is not concerned chiefly to reveal the justice that may consist with wrong-doing. He well deserves to be called, as he has been called, the Defender of the Constitution. There are really no blows to be given by him but defensive ones. He is not a leader, but a follower. His leaders are the men of '87- "I have never made an effort," he says, "and never propose to make an effort; I have never countenanced an effort, and never mean to countenance an effort, to disturb the arrangement as originally made, by which the various States came into the Union." Still thinking of the sanction which the Constitution gives to slavery, he says, "Because it was a part of the original compact- let it stand." Notwithstanding his special acuteness and ability, he is unable to take a fact out of its merely political relations, and behold it as it lies absolutely to be disposed of by the intellect- what, for instance, it behooves a man to do here in America today with regard to slavery- but ventures, or is driven, to make some such desperate answer as the following, while professing to speak absolutely, and as a private man- from which what new and singular code of social duties might be inferred? "The manner," says he, "in which the governments of those States where slavery exists are to regulate it is for their own consideration, under their responsibility to their constituents, to the general laws of propriety, humanity, and justice, and to God. Associations formed elsewhere, springing from a feeling of humanity, or any other cause, have nothing whatever to do with it. They have never received any encouragement from me, and they never will." They who know of no purer sources of truth, who have traced up its stream no higher, stand, and wisely stand, by the Bible and the Constitution, and drink at it there with reverence and humility; but they who behold where it comes trickling into this lake or that pool, gird up their loins once more, and continue their pilgrimage toward its fountain-head. No man with a genius for legislation has appeared in America. They are rare in the history of the world. There are orators, politicians, and eloquent men, by the thousand; but the speaker has not yet opened his mouth to speak who is capable of settling the much-vexed questions of the day. We love eloquence for its own sake, and not for any truth which it may utter, or any heroism it may inspire. Our legislators have not yet learned the comparative value of free trade and of freedom, of union, and of rectitude, to a nation. They have no genius or talent for comparatively humble questions of taxation and finance, commerce and manufactures and agriculture. If we were left solely to the wordy wit of legislators in Congress for our guidance, uncorrected by the seasonable experience and the effectual complaints of the people, America would not long retain her rank among the nations. For eighteen hundred years, though perchance I have no right to say it, the New Testament has been written; yet where is the legislator who has wisdom and practical talent enough to avail himself of the light which it sheds on the science of legislation? The authority of government, even such as I am willing to submit to- for I will cheerfully obey those who know and can do better than I, and in many things even those who neither know nor can do so well- is still an impure one: to be strictly just, it must have the sanction and consent of the governed. It can have no pure right over my person and property but what I concede to it. The progress from an absolute to a limited monarchy, from a limited monarchy to a democracy, is a progress toward a true respect for the individual. Even the Chinese philosopher was wise enough to regard the individual as the basis of the empire. Is a democracy, such as we know it, the last improvement possible in government? Is it not possible to take a step further towards recognizing and organizing the rights of man? There will never be a really free and enlightened State until the State comes to recognize the individual as a higher and independent power, from which all its own power and authority are derived, and treats him accordingly. I please myself with imagining a State at least which can afford to be just to all men, and to treat the individual with respect as a neighbor; which even would not think it inconsistent with its own repose if a few were to live aloof from it, not meddling with it, nor embraced by it, who fulfilled all the duties of neighbors and fellow-men. A State which bore this kind of fruit, and suffered it to drop off as fast as it ripened, would prepare the way for a still more perfect and glorious State, which also I have imagined, but not yet anywhere seen.

Heritable Variation Among Individuals (L11)

[Music] [Music] this is the story of the greatest scientific discovery ever the discovery that everything is made of atoms the vast variety and richness of everything we see around us in the world and beyond how it's built up how it all fits together is all down to atoms and the mysterious laws they obey as scientists delve deep into the atom it's the very part of matter they unraveled nature's most shocking secrets they had to abandon everything they believed in and create a whole new science a science that today underpins the whole of physics chemistry biology and maybe even life itself but for me the story of how humanity solved the mystery of the atom is both inspiring and remarkable it's a story of great geniuses of men and women driven by their thirst for knowledge and glory it's a story of false starts and conflicts of ambition and revelation a story that leads us through some of the most exciting and exhilarating ideas ever conceived of by the human race and for a working physicist like me it's the most important story there is [Music] [Music] on the 5th of October 1906 in a hotel room near Trieste a German science is called Ludwig Boltzmann hanged himself Boltzmann had a long history of psychological problems and one of the key factors in his depression was that he'd been vilified even ostracized for believing something that today we take for granted he believed that matter cannot be infinitely divisible into ever smaller pieces instead he argued that ultimately everything is made of basic building blocks atoms it seems incredible now that Boltzmann's revelation was so controversial but a hundred years ago arguing atoms were real was considered by most to be a waste of time although philosophers since the Greeks had speculated that the world might be made out of some kind of basic unit of matter they realized that they were far too small to see even under the most powerful microscopes speculating about them was therefore a complete waste of time but then in the middle of the 19th century whether or not the atom was real was suddenly a question of burning importance the reason was this steam by the 1850s it was changing the world it powered the mighty engines the trains the ships the factories of the Industrial Revolution so figuring out how to use it more effectively became a matter of crucial commercial political and military significance not surprisingly then it became the key question of 1965 [Music] the demand to build more powerful and efficient steam engines in turn created an urgent need to understand and predict the behavior of water and steam at high temperatures and pressures not the alts Minh and his scientific allies showed that if you imagine steam is made of millions of tiny rigid spheres atoms then you can create some powerful mathematical equations and those equations are capable of predicting the behavior esteemed with incredible accuracy but these same equations plunge Boltzmann and his fellow atomists into controversy their enemies argued that since the atoms referred to in their calculations were invisible they were merely a mathematical convenience rather than real physical objects to claim that imaginary entities were real seem presumptuous even blasphemous you see boss most critics argued that it was sacrilegious to reduce God's miraculous creation down to a series of collisions between tiny inanimate spheres Boltzmann was condemned as an irreligious materialist the tragic irony of Boltzmann's story is that when he took his own life in 1906 he was unaware that he'd been vindicated you see a year before he died a young scientist had published a paper which undeniably irrefutable proclaimed the reality of the atom you might have heard of this young scientist his name was Albert Einstein in 1905 the year before Boltzmann suicide Albert Einstein was 26 years old his brash arrogance had upset most of his professors and teachers and he was barely employable then he got his girlfriend pregnant that was followed by a hasty marriage he needed a job any job having not quite distinguished himself a university he took up a job as a patent clerk here in bern in switzerland he'd moved into the small one-bedroom Apartments on cram gasser with his young wife from a laborer despite dire personal straits the young Einstein had a burning ambition he was desperate to make his mark as a physicist and in 1905 during one miraculous year the mark he made was truly incredible having an undemanding job meant that young einstein had plenty of time on his hands both at work and here in his tiny apartment to think deep thoughts in the space of just a few months he was to publish several papers that would change science forever now everyone's heard of his theory of relativity even if they don't understand it and his paper on the nature of light was to win him the Nobel Prize a few years later but ironically it wasn't either of these two papers that had the most impact on the discovery of atoms the one that made all the difference was a short paper on how tiny grains of pollen danced in water almost 80 years earlier in 1827 a Scottish botanist called Robert Brown sprinkled pollen grains in some water and examined it through a microscope what he found was really strange because instead of the pollen grains floating gently in the water they danced around furiously almost as though they were alive now while this so called Brownian motion was strange scientists soon forgot about it they found it mundane even boring I mean who cared if the pollen giggled about in the water and what had the jiggling to do with atoms anyway for nearly 80 years brown's discovery remained a little-known scientific anomaly then Einstein changed everything in one staggering insight I Stein saw that Brownian motion was all about atoms in fact he realized that the jiggling of pollen grains in water could settle the raging debate about the reality of atoms forever his argument was simple the pollen will only jiggle if they were being jostled by something else so I said that the water must be made of tiny atoms like particles which themselves are jiggling and are continually buffeting the pollen if there were no atoms then the pollen would stay still so Boltzmann and his contemporaries had been rowing furiously about this question for nothing the answer was there all along Einstein proved that for Brownian motion to happen atoms must exist Einstein später went way beyond just verbal arguments with flawless mathematics he proved that the dance of the pollen revealed the size of the atom and it's mind-numbing ly tiny 1/10 of a millionth of a millimeter across a single human hair itself one of the narrowest things visible to the naked eye is over a million atoms wide let me put it another way there are more atoms in a single glass of water than there are glasses of water in all the oceans of the world sort of hurts your head just to think about it Einstein's paper ended the debate about whether the atom was real or not and Boltzmann had been totally vindicated the atom had to be real [Music] [Music] by the early years of the 20th century the atom had arrived scientists we'd argued that the atom was real were no longer heretics in a dramatic sudden reversal they became the new orthodoxy but they were to pay a huge price for their success before that even had a chance to congratulate each other on discovering the atom it ripped the rug out from under their feet and sent them spiraling into a bizarre and at times terrifying new world and it all kicked off here in what by 1910 was the world center for atomic physics Manchester two of the most extraordinary men in the history of science worked here in the physics departments of Manchester University between 1911 and 1916 they were Ernest Rutherford and Niels Bohr on the face of it two very different personalities and the unlikeliest of collaborators Rutherford was from a remote part of New Zealand and grew up on a farm Bohr was born in Copenhagen wealthy and erudite virtually an aristocrat Rutherford was the ultimate experimentalist he loved technology and ingenious arrangements of batteries coils magnets and radioactive rocks but he was also blessed with a profound intuition in contrast war was the ultimate theoretician to him science was about deep thought and abstract mathematics pen and paper chalk and blackboard were his tools logic was his path to truth although their approaches to their work couldn't have been any more different they had one thing in common they were prepared to ditch three centuries of scientific convention if it didn't fit what they believed to be true they were genuine revolutionaries Rutherford and Bohr were two of the most extraordinary minds ever produced by the human race but it would take every bit of their dogged tenacity and inspirational brilliance to take on the atom in 1907 ernest rutherford took over the physics departments in manchester this was a period of momentous scientific change just over ten years earlier in germany came the first demonstration of weird rays that see through flesh to reveal our bones these rays were so inexplicable scientists didn't know what to call them so they were named x-rays and a couple of years after that in Cambridge it was shown that powerful electric currents could produce strange streams of tiny glowing charged particles that were called electrons and in 1896 in Paris came the most significant discovery of all one that more than any other would unlock the secrets of the atom the metal uranium was shown to emit a strange and powerful energy that was named radioactivity it seemed straight out of science fiction radioactive metals were warm to touch they could even burn the skin and the rays could pass through solid matter as if it wasn't there it truly was a marvel of the modern age Rutherford was obsessed with radioactivity all sorts of questions plagued him how has it made why did it come in different forms how far could it travel through a vacuum or through air did it alter the materials that are encountered in Manchester together with his assistants hands Geiger of Geiger counter fame and Ernest Marsden he devised a series of experiments that would probe the Enigma of radioactivity 1909 Manchester University these are the props goldleaf Beaton said it's just a few atoms thick a movable phosphorescent screen that flashed when struck by radioactive rays and inside this box is the star attraction a tiny piece of the metal radium radium is an extraordinarily powerful source of a kind of radioactivity the Rutherford had named alpha rays they weren't really rays they were more like a steady stream of particles and radium spat up these particles like a machine gun that never ran out of bullets Rutherford set his students a simple enough task use the radium gun shoot the alpha radioactivity at the gold leaf and with the phosphorescent plate count the number of particles that come out the other side in practice that meant sitting alone in the dark and counting tiny almost invisible flashes on the phosphorescent screen it was deeply tedious but Rutherford insisted that they keep at it weeks passed and the team of researchers found nothing unusual the alpha particles seemed to punch through the gold almost as though it wasn't there very occasionally they would swerve slightly as they went through hardly front-page news now comes what must be the most consequential off-the-cuff remark in the history of science one that changed the world the story goes that Rutherford bumps into his assistant Geiger in the corridor outside the lab Geiger reported that so far they've seen nothing unusual now in response Rutherford could have easily just nodded and walked on but he didn't he later claimed that he said what he said at the time for the sheer hell of it but I don't believe him Rutherford had great scientific intuition and I think he had a hunch that something was about to happen here's what he said to Geiger tell young Marsden to go back and see if he can detect any alpha particles on the same side of the gold leaf as the radium source in other words see if any alpha particles are bouncing back now it's an extraordinary suggestion from Rutherford and one day he had no logical reason to make after all Geiger Marsden had spent weeks seeing alpha particles do nothing but streams straight through the gold leaf almost as though it wasn't there why would any bounce back the Geiger Marsden were young and in all the big New Zealand er they did their master's bidding and went back into their dark lab and watched patiently for days they saw absolutely nothing they strained their eyes to the points of myopia but didn't see a single alpha particle bouncing back off the gold it seemed that rather for suggestion really was a stupid one but then the impossible happened one afternoon in 1909 Geiger burst into Rutherford's office with some astonishing news very very occasionally an alpha particle would indeed ricochet back off the gold leaf Geiger calculated that only 1 in 8,000 alpha particles would do this it's a tiny percentage but Rutherford's mind reeled with the news he would later say it was like firing a shell at a piece of tissue paper and have it bounce back at you there and then Rutherford knew he'd struck physics cold although it would take him over a year to fully understand why the alpha particles would do this when he did he would show humanity for the first time the inside of an atom now people had barely got used to the idea that atoms existed but now Rutherford knew that this my new world 1/10 of a millionth of a millimetre across had his own internal structure within the atomic there's a sub atomic world and Ernest Rutherford believed he knew what it looked like Rutherford realized that the bouncing alpha particle revealed an atom that was totally unexpected it had no familiar analogy on earth so Rutherford looked for one in the heavens he pictured the atom as a tiny solar system electrons tiny particles of negative electricity orbit around a minut positively charged object called the nucleus [Music] Rutherford calculated that the nucleus was 10,000 times smaller than the atom itself that's why only 1 in 8,000 alpha particles bounce back they're the ones that hit the Tony nucleus by chance the rest whizzed by without hitting anything the first astonishing consequence of this idea is that Rutherford's atom is almost entirely empty space that's why nearly all the alpha particles race through the gold atoms as if there's nothing there there really is nothing there consider the bizarre implications of Rutherford's atom by imagining it on a bigger scale if the nucleus were the size of a football then the nearest electron will be an orbit half a mile away the rest of the atom will be completely empty space let me explain another way if you were to suck out all the empty space from every atom in my body then I would shrink down to a size smaller than a grain of salt of course I'd still weigh the same and if you did the same thing to the entire human race then all 6 billion of us would fit inside a single Apple the atom was unlike anything we had ever encountered before and it would only get stranger and stranger almost immediately a problem surfaced and it was a big one according to the tried and trusted science of the time the electrons should lose their energy run out of speed and spiral into the nucleus in less than a blink of an eye Rutherford's atom contradicted the known laws of science the atom didn't care that it defied scientific convention it's almost entirely empty space and it's gonna stay that way I show no signs of shrinking down to the size of a grain of salt and the earth is well the size of the earth it's not getting smaller not surprisingly all the established scientists of the day including Einstein were battled scientific ideas they put their faith in all their lives had failed completely to explain the atom the atom now required a new generation of scientists to follow in Rutherford's footsteps bold brilliant and above all young it was crucial they had no loyalty or attachment to ideas held by previous generations one of the first of this new breed was niels bohr he sailed from Denmark in 1911 and made his way it's English soil having finished his studies in Copenhagen war decided to move abroad and be at the center of the new physics the trail led you to britain manchester university ernest rutherford or made it his mission to solve the puzzles of why the atom didn't collapse and why there was so much empty space as one of the new breed of theoretical physicists he was fearless in his thinking and was prepared to abandon common sense and human intuition to find an explanation so in a leap of genius he started to look for clues about the atoms structure not by looking at matter but by examining the mysterious and wonderful nature of light our atoms and lights are clearly connected most substances glow when they're heated and for centuries people had realized that different substances glow with their own distinctive colors a bit like a signature so the green of copper the yellow of sodium and the red of lithium these colors associated with different substances are called spectra and Bohr's great insights was to realize that spectra are telling us something about the inner structure of the atom that they could explain all that empty space Bohr's idea was to take Rutherford's solar system model of the atom and replace it with something that's almost impossible to imagine or visualize so sensible ideas like empty space and particles moving around in orbits fade away and they're replaced with something that is one of the most misunderstood and misused concepts in the whole of science the quantum jump now it takes most working physicists many years to come to terms with quantum jumps and in fact or himself said that if you think you've understood it then you haven't really thought about it enough so I'm going to take a deep breath and under 30 seconds try and explain to you one of the most complicated concepts in the whole of science but one that underpins the entire universe Bohr described the atom not as a solar system but as a multi-story building the ground floors where the nucleus lives were the electrons occupying the floors above mysterious laws mean the electrons can only live on the floors never in between and other mysterious laws mean that sometimes that can instantaneously jump from one film to another these are what we call quantum jumps now Bohr had absolutely no idea what these laws were but thinking like this allowed him to make a startling prediction when an electron jumps from a higher floor to a lower one it gives off light more significantly the color of the light depends on how big or small the quantum jump the electron makes so an electron jumping from the third floor to the second floor might give off red light when an electron jumping from the tenth floor to the second floor blue light to test his new theory Bohr used it to make a prediction could it explain the mysterious signature in the spectrum of hydrogen after months of calculating furiously who finally came up with the results and his prediction was surprisingly accurate for the first time ever it looked like the spectrum can be explained back in 1913 that was big news but Bohr's new idea rested on a single seriously controversial supposition why should the electrons in the atom behave as though they were in a multi-story building and why should they magically perform quantum jumps from one story to another there was no precedent for it anywhere else in science when one physicists claimed the jumps were nonsense Moore replied yes you're completely right but that doesn't prove the jumps don't happen only that you cannot visualize them but not being able to visualize things seem to go against the whole purpose of science all the scientists in particular felt that science was supposed to be about understanding the world not about making up arbitrary rules that seemed to fit the data conflict between the two generations of scientists was inevitable cause weird new Adam and his crazy quantum jumps were a shot across the bow silence and the old school reacted and leading the traditionalists was giant of the physics world Albert Einstein he hated all his ideas and he was going to fight them anything from a sexual assault on Nats [Music] borther is undeterred and as the 1920s gone the battery needs for one of the greatest conflicts in all science Woodlawn so far the debates about the new atomic physics had been polite from gentlemen now the two sides wheeled out their biggest guns two of the greatest names in physics they were two very true trusting characters on those dicho for the new revolutionary science was a buttoned-up uber competitive German called Verner Heisenberg for the Conservatives as a debonair byron esque Austrian called Owen Schrodinger [Music] [Applause] Oh in Schrodinger passionate and poetic a philosopher and a romantic he wrote books on the ancient Greeks on philosophy on religion he was influenced by Hinduism there's also a very flamboyant character cool suave sophisticated a dapper dresser and a big hit with the ladies [Music] [Applause] schrödinger's promiscuity was legendary he had a string of girlfriends throughout his married life some of them much younger than him in 1925 38 year-old Schrodinger stayed at the Alpine resort of yoson Switzerland for a secret liaison with an old girlfriend whose identity remains a mystery to this day but their passion proved to be the catalyst but Schrodinger's creative genius another physicist said of Schrodinger's week of sexually inspired physics he had two tasks that week satisfy a woman and solved the riddle of the atom fortunately he was up to both he took de Bru's idea of mysterious pilot waves guiding electrons around an atom one crucial step further he argued that the electron actually was a wave of energy vibrating so fast it looked like a cloud around the atom a cloud like wave of pure energy and what's more he came up with a powerful new equation which completely described this way and so described the whole atom in terms of traditional physics the equation he came up with we now call schrödinger's wave equation it's incredibly powerful what's unique about it is that it features a new quantity called the wave function which Schrodinger claimed completely describe the behavior on the subatomic world [Music] Schrodinger's equation and the picture of the Atome painted created during a sexually charged holiday in the Swiss Alps once again allowed scientists to visualize the atom in simple terms it's hard to overestimate the relief Schrodinger's idea brought to the traditional physics community strange though his picture of the Aten was at least it was a picture and scientists love pictures they allowed them to use their intuition but there was still a deep nagging problem one that the radicals felt Schrodinger just couldn't reconcile his new theory still couldn't account for balls strange instantaneous quantum jumps the time had come for the radicals to hit back [Applause] in the summer of the same year one of Niels Bohr's protegees Verner Heisenberg was travelling to an obscure island of the north coast of Germany he was fiercely competitive and took Schrodinger's ideas as a personal affront he felt strongly that the strangeness of the instant quantum jumps was actually the key to understanding the atom he thought the atom was so unique and unusual it shouldn't be compromised through a simple analogy like a wave or an orbit or even a multi-story building he believed it was time to give up any picture of the atom at all Verner Heisenberg while the true geniuses of the 20th century young athletic a great mountain climber an excellent pianist he was also an exceptional student at the age of just 20 who was well on his way to finishing his ph.d and being courted by the great universities across Europe now in the summer of 1925 he was suffering from a particularly bad bout of hay fever his face was swollen up almost beyond recognition he decided to escape alone here to this beautiful but isolated island of helgeland he walked along the beaches he swam he climbed the rock and he pondered ever since he'd encountered atomic physics Heisenberg felt in his bones that all human attempts to visualize the atom to model it with familiar images would always fail the atom he believed was too capricious too strange to ever be explained that simply so he decided to abandon all pictures of it and describe it using pure mathematics alone but as he pondered he realized that the atom didn't just defy visualization it even defied traditional mathematics it was while he was here on helgeland the Heisenberg had an incredible revelation he realized that in order to describe certain properties of atoms he had to use a strange new type of mathematics it seems that certain properties like where an electron is at a given time and how fast it's moving where multiplied together the order in which you multiply there matters let me try and explain if we multiply two numbers together it doesn't matter which or do we do it in so 3 times 4 is clearly the same as 4 times 3 but when it came to atoms Heisenberg realized that the order in which he multiplied quantities together gave a different answer this quickly led him to other discoveries and he was convinced that he'd cracked a code in the atom that he'd somehow found the hidden mathematics within he was so excited he was also very scared that night he climbed to the top of a rock and sat there waiting till dawn he called it his night of helgeland when he returned to his University in getting and he told his colleague Max Born about it and they then worked together intensely for several months developing a whole new theory of the atom a theory that today we call matrix mechanics [Music] matrix mechanics uses complex arrays of numbers rather like a spreadsheet by manipulating these arrays Heisenberg and his mentor the brilliant physicist max all could accurately predict atomic behavior but from Einstein and the traditionalists this was pure scientific heresy an atom can't actually be a matrix of numbers surely we made of atoms not numbers back in Copenhagen Bohr and Paulie were thrilled with matrix mechanics so what if we couldn't imagine the atom as a physical object they exalted in the purity of the mathematics and launched into vicious attacks against Schrodinger's vulgar sensual waves Heisenberg wrote the more I reflect on the physical portion of Schrodinger's equation the more disgusting I find it in fact it's just [ __ ] but Schrodinger was equally scathing of Heisenberg saying he was repelled by his methods and found his mathematics monstrous in Munich in 1926 their enmity began to reach boiling points Schrodinger was to give a lecture on his wave equation Heisenberg scraped together the money to travel down to Munich for the lecture to finally come face to face with his rival what was at stake was more than just Heisenberg's reputation he believed Schrodinger's simplistic approach wasn't just misguided but totally wrong and his intention was nothing less than to destroy Schrodinger's theory Schrodinger delivers his lecture on the new wave mechanics to a packed audience the standing-room-only he writes down his new wave equation to Schrodinger this describes a real physical picture of the atom with electrons as waves surrounding the atomic nucleus 24-year old Verna Heisenberg is in the audience it can hardly contain himself at the end of the lecture he stands up and delivers a monologue attacking Schrodinger's approach for Heisenberg it's impossible to ever have a picture of what the atom is really like the audience is on Schrodinger side they'd much prefer his simple physical interpretation to Heisenberg's abstract complicated mathematics Heisenberg is booed he's told to sit down and be quiet he leaves the lecture sad and depressed Heisenberg returned to Copenhagen with his confidence severely dented there at the Institute he and Bohr reached their darkest moment almost all of the scientific community was against them they felt isolated desperate their backs were against the wall despite this they stubbornly refused to give up their controversial theory this attic room was Heisenberg study back in 1926 Bohr would come up here night after night we're here in Heisenberg would argue about the meaning of the new quantum mechanics they would argue so passionately but on one occasion apparently Heisenberg was reduced to tears and then as Heisenberg stared out of his attic window in despair the part below an extraordinary thought occurred to him it struck him why an atom can't be visualized why can't be understood intuitively it's not just because it's tiny tricky and difficult is because it's inherently unknowable he realized that there was a fundamental limit to how much we can know about the subatomic world for instance if we know where an electron is at a particular moment in time then we cannot know how fast it's moving but if we knew its speed we wouldn't know his position this ambiguity isn't a shortcoming in the theory itself nor was it due to the clumsiness of the way we carry out our measurements but a fundamental truth about the way nature behaves at the subatomic scale it became known as Heisenberg's uncertainty principle and is probably the most profound incredible yet unsettling concepts in the whole of science [Music] what Heisenberg had uncovered through his abstract matrix mechanics was a deep and shocking truth about the atomic world atoms are willfully obscure we can never fully know an atoms position and speed simultaneously the atomic world just refuses to allow that to happen it was completely mind-boggling but once they accepted it Heisenberg and Bohr who found the boost of confidence to be even more bold they realized uncertainty forced them to put a paradox right at the very heart of the atom atoms are not just unimaginable they're self-contradictory they behave both like particles and waves and it gets weirder when you're not looking at an atom it behaved like a spread-out wave but when you look to see where it is it behaves like a particle this is insane first atoms couldn't be visualized at all now it seems they change completely in character depending on whether or not you're looking at them the uncertainty principle had changed everything it revealed a shocking contradiction at the heart of nature everything we see is made of atoms and yet atoms themselves are unknowable they can only be understood through mathematics for the first time for Bohr and Heisenberg everything about the atom fell into place by the autumn of 1927 full of confidence and smarting for a fight they knew they were finally ready to take on the Conservatives [Music] for this physics showdown they chose the Solvay conference in Brussels all the world's leading atomic physicists would attend if war and Heisenberg was successful then they would lead a total scientific revolution this is amazing I'm looking at original footage of the Solvay delegates coming out of these doors there's Bohr talking to Schrodinger and and this Heisenberg behind them and there's Paolo Li strange looking guy on there's Einstein coming down with a big smile on his face for the week of the conference all that the delegates could think and talk about was Bohr's quantum mechanics with uncertainty now a central plank it was a truly formidable theory and over the week the final showdown played out between Bohr and his archrival Albert Einstein Einstein hated quantum mechanics and every morning he'd come to war with an argument that he felt picked a hole in the new theory war would go away very disturbed and think very hard about it and by the end of the day he'd come back with a counter argument that dismissed Einstein's criticism and this happened day after day until by the end of the conference Bohr had brushed aside all of Einstein's criticisms and Bohr was regarded as having been victorious and with that his vision play-actor which became known as the Copenhagen interpretation was suddenly at the very heart of atomic physics at the end of the conference they all gather for the team photo never before or since have so many great names of physics being together in one place at the front the elder statesmen of physics Hendrik Lorentz flanked on either side by Madame Curie and Albert Einstein Einsteins looking rather glum because he's lost the argument Louis debris has also failed to convince the delegates of his views victory goes to Niels Bohr he's feeling very pleased with himself next to him one of the unsung heroes of quantum mechanics the German Max Born who developed so much of the mathematics and behind them the two young disciples of Bohr Heisenberg and Pauli Poly's looking rather smugly across at Schrodinger bit like the cat who's got the milk this was the moment in physics when it all changed the old guard was replaced by the new chance of probability became interwoven into the fabric of nature itself and we could no longer describe atoms in terms of simple pictures but only using pure abstract mathematics the Copenhagen view had been victorious although Einstein went to his grave never believed in quantum mechanics solve a 1927 was the turning point at which the rest of the science establishments came to embrace the Copenhagen interpretation and that interpretation is still accepted today all the physics that I use in my research certainly the quantum mechanics that I teach my students and that fills the textbooks on my shelves is based on ideas that were hammered out and crystallized here at the Solvay conference in October 1927 in a sense everything I know about the way the world around me is made up started here the quantum mechanical description of the atom is one of the crowning glories of human creativity over the last of 18 years it has been proven right time after time and it's Authority has never been in doubt it's a monumental scientific achievement between 1905 and 1927 science changed our view of the world it also changed our view of science itself as scientists probed the tiniest building blocks of matter they created the most successful and powerful theory ever quantum mechanics it allows us to describe what everything in the universe is made of how it interacts and how it all fits together but it comes at a huge price at its most fundamental level we have to accept that nature is ruled by chance and probability Heisenberg's uncertainty principle dictates that there are certain limits on the sorts of questions we can ask the atomic world and most crucially while we now know so much more about what an atom is and how it behaves we have to give up any possibility of imagining what it looks like our human nature has forced us to ask questions of everything we see around us in the world what we've discovered has been beyond our wildest imagination [Music]

Key distinction: Glaucoma → pressure/optic nerve Cataract → cloudy lens Acute angle-closure glaucoma: * Severe eye pain * Headache * Halos * Nausea/vomiting * Red eye Emergency. ⸻ Hearing Loss Conductive Problem with sound transmission through outer/middle ear. Sensorineural Problem involving inner ear/auditory nerve. Communication: * Face patient * Speak clearly * Don’t shout * Reduce background noise * Verify understanding ⸻ 🔥 14. BURNS Think: Airway → Breathing → Circulation Inhalation injury Red flags: * Facial burns * Soot * Singed nasal hairs * Hoarseness * Stridor * Carbonaceous sputum Airway edema can worsen rapidly. ⸻ Burn priorities * Airway * Breathing * Circulation * Fluid resuscitation for significant burns * Pain management * Infection prevention * Temperature control * Nutrition * Wound care ⸻ 15. WOMEN’S & MEN’S HEALTH Menopause Decrease in estrogen. Common: * Hot flashes * Night sweats * Sleep problems * Vaginal dryness * Mood changes Long-term: * Bone loss * Cardiovascular considerations ⸻ Birth Control Know: * Effectiveness * How it is used * Contraindications * STI protection Most hormonal birth control does NOT protect against STIs. Condoms help reduce STI transmission. ⸻ STIs Examples: * Chlamydia * Gonorrhea * Syphilis * HPV * Herpes * HIV Nursing: * Testing * Treatment adherence * Partner notification/treatment when appropriate * Safer sex education * Prevention ⸻ Breast Cancer Warning signs: * New breast lump * Skin changes * Nipple changes/discharge * Axillary lymph node changes Know current screening recommendations and individual risk factors. ⸻ Prostate Cancer Possible: * Urinary hesitancy * Weak stream * Frequency * Hematuria Important: Early prostate cancer may have no symptoms. ⸻ 🚨 16. EMERGENCY NURSING Shock Basic concept: Tissues aren’t receiving enough oxygen/perfusion. Signs: * Tachycardia * Hypotension * Altered LOC * Cool/clammy skin in many shock states * Decreased urine output * Tachypnea Major types Hypovolemic → blood/fluid loss Cardiogenic → pump failure Distributive → vasodilation (e.g., septic/anaphylactic) Obstructive → obstruction to circulation Priority: ABCs + identify/treat cause + restore perfusion. ⸻ Hemorrhage Look for: * Tachycardia * Hypotension * Pallor * Weakness * Decreased LOC * Decreased urine output Priority: Control bleeding + support circulation + escalate. ⸻ Anaphylaxis Severe allergic reaction. Signs: * Airway swelling * Wheezing * Dyspnea * Hypotension * Hives * GI symptoms FIRST-LINE MEDICATION: IM epinephrine Do not delay epinephrine while waiting for other treatments. ⸻ 💧 17. FLUID & ELECTROLYTES Dehydration Signs: * Thirst * Dry mucous membranes * Tachycardia * Hypotension * Poor skin turgor * Decreased urine output * Weight loss ⸻ Fluid overload Signs: * Edema * Crackles * Dyspnea * Weight gain * JVD * Hypertension ⸻ Potassium Hypokalemia Think: Weak + irregular heart Causes: * Diuretics * GI losses Hyperkalemia Think: Dangerous heart rhythm Causes: * Renal failure * Tissue breakdown * Certain medications ⸻ Acid-Base Use: ROME Respiratory = Opposite Metabolic = Equal Examples: Respiratory acidosis CO₂ ↑ → pH ↓ Respiratory alkalosis CO₂ ↓ → pH ↑ Metabolic acidosis HCO₃ ↓ → pH ↓ Metabolic alkalosis HCO₃ ↑ → pH ↑ ⸻ 👶 MATERNAL-CHILD NURSING Prenatal Care Monitor: * Maternal vital signs * Weight * Blood pressure * Urine * Fetal growth * Fetal heart rate * Laboratory screening * Risk factors Important warning signs: * Vaginal bleeding * Severe headache * Visual changes * Severe abdominal pain * Fluid leakage * Decreased fetal movement * Sudden swelling/other signs of hypertensive disorders ⸻ Fetal Development High-yield concept: First trimester → organ formation Second trimester → growth and development Third trimester → maturation and preparation for birth ⸻ Labour Stage 1 Onset of true labour → complete cervical dilation. Stage 2 Complete dilation → birth of baby. Stage 3 Birth of baby → delivery of placenta. Stage 4 Immediate postpartum recovery. ⸻ Apgar At approximately 1 and 5 minutes. A P G A R A – Appearance P – Pulse G – Grimace A – Activity R – Respiration Each scored 0–2. Apgar helps assess newborn adaptation; it does not by itself diagnose asphyxia or determine long-term prognosis. ⸻ Newborn Assessment Assess: * Respiratory effort * Heart rate * Temperature * Colour * Tone * Feeding * Reflexes * Weight * Head circumference * Urine/stool ⸻ Breastfeeding Benefits: * Nutrition * Immune protection * Bonding Signs of effective feeding: * Good latch * Audible swallowing * Appropriate wet/dirty diapers * Expected weight pattern ⸻ 👶 PEDIATRIC NURSING Development General progression: Head → toe Simple → complex Large muscles → fine motor Always consider developmental stage when communicating with children. ⸻ Pediatric Safety Big priorities: * Falls * Choking * Burns * Poisoning * Drowning * Car-seat safety * Medication dosing * Safe sleep Medication principle Pediatric medications are often based on: weight (kg) Always verify calculations and concentrations. ⸻ Pediatric Asthma Same basic principles as adults: * Bronchodilator for acute symptoms * Controller medications for long-term control * Trigger avoidance * Asthma action plan ⸻ RSV Common in infants/young children. Signs: * Rhinorrhea * Cough * Wheezing * Increased work of breathing * Poor feeding Priority: Respiratory assessment and hydration. ⸻ Croup Classic: Barking cough + stridor Often worse at night. Severe respiratory distress requires urgent intervention. ⸻ Cystic Fibrosis Thick secretions affect lungs and GI system. Think: “Thick mucus + lung infections + malabsorption.” Nursing: * Airway clearance * Nutrition * Pancreatic enzymes when prescribed * High-calorie/high-protein nutrition * Infection prevention ⸻ Gastroenteritis Major concern: Dehydration. Assess: * Wet diapers/urine * Mucous membranes * Tears * Capillary refill * Weight * Activity/LOC ⸻ Pyloric Stenosis Classic: Projectile, non-bilious vomiting Often occurs in young infants. Possible: * Hunger after vomiting * Dehydration * Weight loss ⸻ ASD vs VSD ASD Hole between atria. VSD Hole between ventricles. VSD can produce: A significant murmur and increased pulmonary blood flow. ⸻ Sickle Cell Disease Problem: Abnormal hemoglobin → sickled RBCs → vaso-occlusion and hemolysis. Crisis triggers: * Dehydration * Infection * Hypoxia * Stress Management: * Hydration * Oxygen if hypoxemic * Pain management * Treat infection * Rest * Disease-specific therapies ⸻ Meningitis Think: Fever + headache + stiff neck + altered mental status May also have: * Photophobia * Vomiting * Seizures Emergency. Use appropriate isolation precautions according to suspected organism and institutional policy. ⸻ Hydrocephalus Excess CSF. Infants may have: * Increasing head circumference * Bulging fontanelle * Irritability * Poor feeding * “Sunsetting” eyes Older children: * Headache * Vomiting * Visual changes * Altered LOC ⸻ 🧠 MENTAL HEALTH NURSING Therapeutic Communication DO: * Use open-ended questions * Listen * Reflect * Clarify * Validate feelings * Maintain appropriate boundaries DON’T: * Give false reassurance * Judge * Argue * Give excessive advice * Say “everything will be fine” ⸻ Depression Symptoms: * Persistent sadness * Anhedonia * Sleep changes * Appetite changes * Fatigue * Poor concentration * Feelings of worthlessness * Suicidal thoughts Nursing priority: Assess suicide risk directly. ⸻ Bipolar Disorder Mania * Elevated/irritable mood * Increased energy * Decreased need for sleep * Rapid speech * Impulsivity * Grandiosity Nursing: * Reduce stimulation * Maintain safety * Set clear limits * Encourage nutrition/hydration * Administer medications as prescribed ⸻ Schizophrenia Positive symptoms: * Hallucinations * Delusions * Disorganized speech/behaviour Negative symptoms: * Flat affect * Social withdrawal * Reduced motivation Communication Don’t argue with delusions. Instead: Acknowledge the patient’s feelings while presenting reality. ⸻ OCD Obsessions: Intrusive thoughts Compulsions: Repetitive behaviours/mental acts ⸻ Eating Disorders Watch: * Electrolytes * Cardiac rhythm * Nutrition * Weight * Refeeding complications * Psychological safety ⸻ Substance Use Priorities: * Airway/breathing/circulation * Overdose recognition * Withdrawal * Safety * Nonjudgmental communication ⸻ 🧪 HIGH-YIELD DIAGNOSTIC TEST THINKING When you see a test question, ask: “Why are they ordering this?” Examples: CT head after sudden neurological deficit → looking for bleeding/structural abnormalities. MRI → detailed soft tissue/neurological/musculoskeletal imaging. ECG → electrical activity/ischemia/dysrhythmia. Troponin → myocardial injury. HbA1c → long-term glucose control. Creatinine/GFR → kidney function. INR → warfarin effect. Culture and sensitivity → organism + effective antimicrobial. Pulmonary function test → lung function/obstruction/restriction. ⸻ 💊 PHARMACOLOGY MASTER MEMORY MAP Instead of memorizing 100 medications individually, memorize the danger associated with each class: Drug/Class Think Insulin Hypoglycemia Opioids Respiratory depression Warfarin Bleeding + INR Heparin Bleeding + HIT Furosemide Fluid/electrolyte loss Digoxin Bradycardia/toxicity ACE inhibitors Hyperkalemia + cough/angioedema Beta blockers Bradycardia/hypotension Steroids Hyperglycemia + infection NSAIDs GI bleeding + kidney injury Statins Muscle/liver effects Bronchodilators Tachycardia/tremor Inhaled steroids Oral candidiasis Antibiotics Allergy + C. diff ⸻ 🚨 THE “PRIORITY QUESTION” METHOD When you’re stuck on an exam question, ask: 1. Is the airway threatened? If yes → AIRWAY 2. Is breathing compromised? If yes → BREATHING 3. Is circulation/perfusion compromised? If yes → CIRCULATION 4. Is there an acute neurological deterioration? Think neurological emergency. 5. Is there a safety risk? Falls, suicide, aspiration, seizures, etc. 6. Which patient is deteriorating? Unstable beats stable. ⸻ ⭐ TOP THINGS I WOULD MEMORIZE FIRST If you have limited study time, prioritize these: 🚨 Emergencies * Anaphylaxis → IM epinephrine * Stroke → BE FAST + last known well * MI → ECG + rapid intervention * Sepsis → early recognition + rapid treatment * Tension pneumothorax → emergency * Severe hypoglycemia → rapid glucose treatment * Status epilepticus → emergency * Increased ICP → neurological deterioration * Hemorrhage → control bleeding + perfusion * Severe burns → ABCs 💊 Medications * Insulin → hypoglycemia * Morphine → respiratory depression * Warfarin → INR/bleeding * Heparin → bleeding/HIT * Digoxin → pulse/potassium/toxicity * Furosemide → fluid/electrolytes * Nitroglycerin → hypotension + PDE-5 interaction * Steroids → infection/hyperglycemia * Antibiotics → allergy/C. diff * Inhaled steroids → rinse mouth 🧪 Labs * Hb → oxygen carrying * WBC → infection/immune response * Platelets → bleeding/clotting * INR → warfarin * Glucose → current sugar * HbA1c → long-term glucose * Creatinine/GFR → kidney * K⁺ → heart rhythm * Na⁺ → neurological/fluid balance * Culture → organism * Sensitivity → antibiotic choice 🩺 Nursing skills * Infection control * Medication administration * IVs * Oxygen * Suction * Tracheostomy * Chest tubes * Urinary catheter * Wound care * Ostomy care * Vital signs * Neurovascular assessment * Respiratory assessment ⸻ 📚 How I’d recommend studying this huge syllabus Don’t try to study all of these diseases in one sitting. Use system blocks: Day 1: Diabetes + cardiovascular Day 2: Respiratory + renal Day 3: GI + liver Day 4: Hematology + immune/infection Day 5: Neuro + musculoskeletal Day 6: Maternal/newborn Day 7: Pediatrics Day 8: Mental health Day 9: Pharmacology Day 10: Labs + diagnostics + clinical skills Day 11: Emergency/priority questions Day 12: Full mixed practice exam + review weak areas For each condition, make yourself answer only 5 questions: 1. What is happening? 2. What will I assess? 3. What is the biggest complication? 4. What will I do first? 5. What do I teach the patient? That approach will help you think like a nurse rather than memorize isolated facts, which matches the study framework you were given.
