What is Science?
  • Science is a systematized body of knowledge based on observation and experimentation.
  • It's a branch of knowledge dealing with the phenomena of the universe and their laws.
  • It is a particular branch of knowledge distinct from art and technology.
  • The word "science" comes from the Latin "scientia," meaning knowledge.
  • Science, from about the sixteenth century, has come to mean knowledge about the natural world acquired by observation and experiments, as distinct from knowledge acquired by reasoning alone, insight, or revelation.
  • Science is the attempt to understand and explain natural phenomena by using systematic observation or experiment, and applying reason to the knowledge obtained to infer testable laws and make predictions or retrodictions.
  • Retrodiction: A result that occurred in the past and is deduced or predicted from a later scientific law or theory.
  • Science aims to formulate a law or theory to explain the invariable behavior of a system of phenomena.
  • Laws or theories are used to predict future outcomes by applying them to specific phenomena within the system. For example, Newton's laws of motion are used to predict the result of firing a specific rocket.
  • Science focuses on what can be observed and tested, such as physics, chemistry, astronomy, biology, and medicine.
  • Things that cannot be observed and tested, like angels, spirits, the afterlife, and sin, are not science.
  • Science is knowledge based on rationalism (what can be thought) and empiricism (what can be tested).
  • Science seeks explanations for natural phenomena, answering the question 'Why.'
  • Examples include explaining natural disasters, mirages, refraction, children wearing shoes backward, and hysteria.
  • Science adheres to the concept of Cause → Effect.
  • Explanations lead to hypotheses, theories, and laws, such as:
    • Newton's Law of Gravity
    • Snell's Law of Refraction
    • Einstein's Law
PseudoScience
  • Pseudoscience is false science and not a rational science.
  • Examples include astrology, myths, alternative medicine, meditation, and spiritualism.
Teknologi (Technology)
  • Technology addresses the question 'How' and produces products or techniques to solve problems; for instance:
    • How to overcome flood problems in Shah Alam or Kuala Lumpur (Solutions: SMART Tunnel, retention ponds, river enlargement, household retention).
    • How to overcome rising oil prices (Solutions: biofuel, batteries, solar power, water + petrol, fuel savers).
    • How to overcome increased electricity bills (Solution: electricity-saving devices).
Perbezaan Sains dan Teknologi (Differences Between Science and Technology)
ScienceTechnology
Answers why a phenomenon occursHow to solve a problem
Produces theories & lawsProduces a solution & things
Scientist - CauseTechnology - Solution
Examples: High rainfall, monsoon, loggingSMART Tunnel, Retention lake, Wider rivers
Perkaitan Sains dan Teknologi (Relationship Between Science and Technology)
  • Technology predates science.
    • Axes, boats, and pyramids are technologies that didn't require scientific knowledge.
    • Early technology was created without scientific knowledge.
  • Science began with the Greeks, who developed scientific thought and philosophy.
  • Rome produced technology: buildings, coliseums, theaters, roads.
  • Technology requires science.
Sains Yunani vs Sains Moden (Greek Science vs. Modern Science)
SAINS YUNANI (GREEK SCIENCE)SAINS MODEN (MODERN SCIENCE)
Deduksi (Deduction)Induksi (Induction)
teori tanpa pemerhatian/ujikaji (theory without observation/experiment)pemerhatian/ujikaji (observation/experiment)
  • Examples of Greek Science:
    • Men have more teeth than women.
    • Men's brains are larger than women's.
    • The king bee is male.
    • Heavy objects fall faster than light objects.
The Female in Aristotle's Biology (Robert Mayhew)
  • Aristotle made seemingly bizarre statements about the differences between males and females.
  • For example, he said that females have fewer teeth than males.
  • Some scholars believe Aristotle applied biased generalizations rather than engaging in empirical research.
  • Aristotle referred to queen bees as kings.
Scientific Method
  • The scientific method seeks to understand why things happen as they do in the natural world.
  • Until the mid-19th century, little was known about infectious diseases.
  • In the mid-1800s, Ignaz Semmelweis discovered that the death rate from childbed fever was five times higher in the hospital ward where patients were treated by physicians than in another ward where women were seen only by midwives.
  • Semmelweis speculated that childbed fever is caused by something that physicians come into contact with in the autopsy room and then inadvertently transmit to pregnant women, which he termed cadaveric matter.
Scientific Method (pg2)
  1. Identify a problem: Start with a ‘Why’ question.
  2. State a hypothesis: an unproven assumption or intellectual guess.
  3. Perform an experiment & observation.
  4. Record, analyze data, draw a conclusion, and publish a report.
  5. If result of experiment = hypothesis, accept the hypothesis.
  6. Else reject the hypothesis and reformulate a new one.
  7. Proposed an explanation and a theory that X causes Y.
Scientific Method - Example 1
  • Kanak-Kanak Pakai Kasut Terbalik (Children wear shoes in reverse)
    • Identify a problem: Why do children wear slippers in reverse?
    • State a hypothesis: Because it is not easy to take off from the feet.
    • Perform experiment & observation: Create slippers that are not easy to take off and tested on a group of children.
    • Record, analyse data, draw a conclusion and publish report: The findings are published in a journal.
    • Proposed explanation & a theory: The hypothesis is accepted as a theory to explain why children wear slippers in reverse.
Scientific Method - Example 2
  • Kajian Gamat (Sea Cucumber research)
    • Identify a problem: Malays get sick because they like to eat things that are not nutritious such as budu, cencalok, tempoyak, belancan and gamat.
    • State a hypothesis: Gamat has a negative impact on health.
    • Perform the experiment & observation: Gamat was tested on mice, and the result was not the same as the hypothesis. Then, the hypothesis is rejected or modified.
    • Change the hypothesis: Gamat has a positive effect on health.
    • Perform the experiment & observation: Gamat was tested on mice with wounds. The wounds on the mice healed quickly.
    • Record, analyse data, draw a conclusion and publish report: The findings are published in a journal and can be used to support or criticize findings.
    • Proposed explanation and a theory: Gamat can heal wounds.
Scientific Method - Placebo Effect
  • The placebo effect is when the mind influences behavior.
  • In an example, regular flavored water is presented as a tonic.
Scientific Method - Observation & Experiment
  • Observation is a key component of the scientific method.
  • James Peebles, Nobel Prize winner (2019) stated that theory is empty without observation and theoretical discovery is meaningless without evidence.
1.3 Induction
  • Induction is reasoning from particulars to general (universal), from the parts to the whole, from a limited number of specific facts (observations) to a general conclusion.
  • It involves drawing general conclusions from limited observations and experimental results.
Example of Induction 1 - Tongkat Ali
  • Particulars (Experimental results):
    • Ali drinks Tongkat Ali → strong.
    • Abu drinks Tongkat Ali → strong.
    • Kassim drinks Tongkat Ali → strong.
    • Salmah drinks Tongkat Ali → strong.
    • Fatimah drinks Tongkat Ali → strong.
  • General conclusion: Tongkat Ali gives strength.
Example of Induction 2 - Brazil
  • Particulars (Observations):
    • Brazil vs France → Brazil wins.
    • Brazil vs Argentina → Brazil wins.
    • Brazil vs England → Brazil wins.
    • Brazil vs Italy → Brazil wins.
    • Brazil vs Korea → Brazil wins.
  • General conclusion: Brazil is a strong team.

  • General conclusion: The ending 'bit' in Malay means small.
Example of Induction 5 - Gerrymandering
  • Massachusetts + salamander, from the supposed similarity between a salamander and the shape of a new voting district in a map
Example of Induction 6 - Bahasa (Language)
  • PEMERHATIAN KEPADA KESIMPULAN (Observation to Conclusion)
    • Pemerhatian: sabit, kerambit, ketumbit, terbit, bimbit, cubit, bukit, rakit, ungkit, sakit, jangkit, bangkit, melekit, pipit, sempit, sumpit, kepit, cepit, sepet, sepit, apit, parit, buncit, runcit, pancit, melecit, bintik, batik, cantik, detik, jentik, lentik, petik, ketik, itik, titik, bantut, kontot, catut, balik, belek, bilik, celik, golek, adik, bodek, cerdik, gedik, gelek, pendek, tindik
      • Kesimpulan umum: Akhiran bit, kit, pit, cit, tik, tut, lik, dik - menandakan kecil (General conclusion: The ending bit, kit, pit, cit, tik, tut, lik, dik - means small.)
Induction - Parts to Whole
  • Daun, Bunga, Ranting, Buah, Dahan, Cabang, Batang, Akar
  • biji = whole (seed = whole)
  • _Hamzah Fansuri, "The seed is the treasure. In it there are roots, stems, branches, limbs, twigs, leaves, flowers, fruit - all complete in one seed."
Induction - Istaqra'
  • اسْتَقْرَأَ : اسْتَخْرَجَ مَبْدَأَ عَامَّا مِنْ تَفَاصِيلَ مُختلفة

  • menyimpulkan suatu kaedah umum daripada pelbagai contoh/uraian khusus (concluding a general rule from various specific examples/descriptions)

  • to generalize, derive a general principle from particulars

  • Al-Ghazali mendefinisikan istiqra' sebagai berikut (defines istiqra' as follows):

    • أما الاستقراء فهو عبارة عن تصفح أمور جزئية ليحكم بحكمها على أمر يشتمل تلك المجزئيات
    • _Artinya: (Meaning:)
    • "Adapun istiqra' adalah rumusan tentang penelitian terhdap perkara-perkara partikularistik, untuk menghukumi dengan hukumnya sesuatu yang mencakup partikular-partikular itu."
Induction - Kata akar Istaqra'
  • KATA AKAR Mengumpul juzuk2 menjadi satu
  • قَرَأ
  • Membaca
  • قَرَأ الشَّيْء: معهمقون اي اكن سوات. (He read the thing, i.e. he made it real.)
  • قَرَأَ الْكِتَابَ: ممباج اي اكن كتاب. (He read the book, i.e. he took from the book.)
  • قَرَأ 1. 3, [aor. 2,] inf. n. 3, IIe collected together the thing; put it, or drew it, together; (S, O, K, TA ;) part to part, or portion to portion. (S, O, TA.) [This seems to be generally regarded as the primary signification.] Hence
1.4 Deduction
  • Deduction is reasoning from general to particulars, from universal/whole to specific facts.
  • Once a general knowledge (law or theory) is available, it can be drawn to make predictions and offer explanations.
  • It involves reasoning from general conclusions/laws to specific instances.
Examples of Deduction
  • General conclusion (Law/Theory/Whole):
    • Tongkat Ali gives strength
  • Prediction (Particulars/Parts):
    • Pak Mat minum Tongkat Ali ® ?
    • Ah Chin minum Tongkat Ali ® ?
    • Samy minum Tongkat Ali ® ?
  • General conclusion (Law/Theory/Whole):
    • Brazil is a strong team
  • Prediction (Particulars/Parts):
    • Brazil vs Malaysia ® ?
    • Brazil vs Singapore ® ?
    • Brazil vs China ® ?
  • General conclusion (Law/Theory/Whole):
    • All metals expand when heated

  • Ibn Malka al-Baghdadi (1087-1165 m)
    • Centuries before Galileo, Ibn Malkā made it clear that free-falling bodies would have the same velocity if dropped in a vacuum.
Deduction - Aristotle
  • ARISTOTLE - DEDUCTION
  • The obvious objection to all this from the modern point of view is that there is little about the role of actual sensory experience in the acquisition of knowledge of how things work.
  • Aristotle's logic was deductive and, although he took great interest in empirical data and his knowledge of natural phenomena, especially zoology and botany, was vast, apparently he never carried out any experiments.
Example of Deduction
  • Hukum Umum: Lebih Besar Lebih Baik (General Law: Bigger is better)
    • Analogi :Telor besar lebih baik, Buah besar lebih baik, Tamar besar lebih baik, Ayam besar lebih baik, Bawang besar lebih baik, Ikan besar lebih baik, Udang besar lebih baik (Analogy: Big eggs are better, Big fruit is better, Big dates are better, Big chickens are better, Big onions are better, Big fish are better, Big shrimp are better)
  • Hukum Umum: Putih lebih baik (General Law: White is better)
    • Juzuk : Orang putih hebat , Tepung putih, Gula putih, Garam putih, Beras putih, Bawang putih lebih putih (Parts: White people are great, White flour, White sugar, White salt, White rice, Garlic is whiter)
1.5 Kebenaran dalam Sains (Truth in Science)
  • Bukan kebenaran muktamad (Not absolute truth)
  • Bukan penjelasan yang sempurna (Not a perfect explanation)
  • Suatu teori sains tidak bertahan lama (terus berubah) kerana boleh disangkal (refute/falsified) dengan penemuan/teori baharu (A scientific theory does not last long (constantly changing) because it can be refuted/falsified with new findings/theories)
  • Suatu teori sains dianggap benar selagi ia berguna dan dapat menjelaskan dengan logik suatu fenomena (A scientific theory is considered true as long as it is useful and can logically explain a phenomenon)
  • Teori Antonie Lavoiser disangkal setelah 20 tahun (Antonie Lavoiser's theory was refuted after 20 years)
  • Uji kaji (Pariculars/parts)

  • Theories may be refuted/falsified by a new and contrary evidence.

  • If a theory cannot be refuted (falsified), if there is no possible evidence that could ever prove they are wrong, then it is not scientific.

  • Irrefutable theory cannot be scientific.

  • Non Refutable / Falsified

    • Susah untuk diterima atau disangkal kerana tidak dapat dibuktikan secara saintifik

  • Andaian dalam Sains
    Causality (Cause-Effect) Sains mencari penjelasan sebab (cause) mengapa sesuatu fenomena itu berlaku. Contoh : Sebab (Cause) Akibat (Effect) : Hujan Selesema Ubat Sembuh Makan Kenyang Baja Pokok subur

  • Andaian dalam Sains
    inDisebabkan sifat sains yang samar-samar, tidak jelas dan hanya tahu yang zahir sahaja
    Kelebihan & Keterbatasan Kaedah Sains

  • Advantages of Scientific Method (pg 13)
    Logical, Repeatable and Objective, Self-correcting
    Advantages of Scientific MethodLogicalBoleh dilihat dan logik kerana berasaskan fakta dari pemerhatian dan ujikaji menggunakan kaedah induksi. Contoh: PemerhatianSalmah makan panadol Salmah sembuh pening kepalaAminah makan panadol Aminah sembuh pening kepalaKhatijah makan panadol Khatijah sembuh pening kepalaKesimpulan Umum (Konsep Sebab Akibat)Panadol Sembuh pening kepala
    Advantages of Scientific Method Repetable and Objective Boleh diulang oleh sesiapa pun dan hasil ujikaji tetap sama. Jawapannya bersifat objektif Contoh: Untuk mengkaji sama ada minuman bersifat asid dan alkali. Sekiranya kertas litmus bertukar dari merah ke biru, maksudnya minuman tersebut berasid, sebaliknya alkali. Ujikaji ini boleh diulang beberapa kali dan jawapannya tetap sama. Self-correcting Sains bersifat terbuka. Jika hasil ujikaji tidak sama dengan hipotesis, ahli sains menerima keputusan tersebut dan tidak akan mempertahankan hipotesisnya kerana tidak ada kepentingan peribadi.
