Three-Age System
A system introduced by Christian Jürgensen Thomsen in 1837 that classifies ancient ages based on tool developmental stages, specifically stone, bronze, and iron.
Stone Age
A prehistoric period spanning roughly 3.4 million years, ending between 8700 BCE and 2000 BCE, characterized by weapons and tools made of stone, wood, and bone.
Galileo Galilei
Promoted experimental physics and observational astronomy by discovering more about inertia and discovering new moons and planetary laws with his mad telescope skills
Tycho Brahe
Was the one major Scientific Revolution physicist who believed in a geocentric universe
Paracelsus
A doctor who has the crazy idea not to treat people’s “imbalance in the humors” with leeches and traditional remedies, he instead looks at the chemical causes behind sicknesses to treat patients
Paleolithic Period
Known as the Old Stone Age, this is the longest phase of human history where humans were primarily food gatherers.

Mousterian Tools
A Middle Paleolithic stone tool kit including purposefully prepared cores and specialized flake tools used by Neanderthals and early Homo sapiens.
Mesolithic Period
The Middle Stone Age, identified by the use of small chipped stone tools called microliths and the transition to semi-settled life.
Microliths
Small, refined chipped stone tools and retouched bladelets characteristic of the Mesolithic period.

The first period in which metal was regularly used for tools, specifically copper and the alloy bronze.
Iron Age
The period following the Bronze Age where iron, which has a melting point of 1538∘C, replaced bronze due to its superior strength and abundance.

An alloy of iron and carbon developed during the Iron Age to create stronger materials.
Dark Middle Age
The period from 450 to 1000 A.D., starting with the fall of the Roman Empire and often associated with a perceived lack of scientific progress.
High Middle Age
The period from 1000 to 1450 A.D. characterized by economic expansion, the growth of towns, and the establishment of the first universities.
Scientific Revolution
The period between Copernicus and Newton (1440-1690 AD) that transformed societal views of nature through mathematics, physics, and the experimental method.
Antonie van Leeuwenhoek
The Father of Microbiology who used microscopes to discover bacteria, which he described as animalcules.
William Harvey
The scientist who discovered that the heart acts like a pump to circulate blood throughout the body using valves and heartbeats.
Robert Boyle
The Father of Modern Chemistry who discovered the law regarding gas pressures and volumes.
Johannes Kepler
Tycho Brahe’s assistant who developed the Three Laws of Planetary Motion, proving that orbits are calculated mathematically and are elliptical.
Nicolaus Copernicus
The astronomer who first proved that the earth revolves around the sun, initiating the Copernican Revolution.
Francis Bacon
A philosopher who supported the empirical method and inductive reasoning, advocating for truths derived from concrete observations.
René Descartes
A mathematician and philosopher who promoted deductive reasoning and the scientific method, famously stating, "I think, therefore I am."
Newton’s Second Law of Motion
The physical principle stated as Force=mass×acceleration.
The Enlightenment
Also known as the Age of Reason, this movement used scientific methods to understand and improve aspects of society and human nature.
Industrial Revolution
A period of complex technological inventions, such as the steam engine and power loom, that replaced human and animal labor with machine power.
Information Age
Also called the Digital Age, starting around the 1970s, it is characterized by an economy founded on computerized information.
Science (Body of Knowledge)
A systematized body of knowledge based on facts gathered through observations, experiences, and experiments to formulate a verifiable conclusion or law.
Technology (Application)
The application of scientific knowledge to the practical aims of human life or to the change and manipulation of the human environment.
Science vs. Technology
Science explores for the purpose of knowing, while technology explores for the purpose of making something useful from that knowledge.
Three-Age System
A system of classifying ancient ages into groups based on tool developmental stages, considered archaeology's first paradigm.
Christian Jurgensen Thomsen
The individual who first fully introduced the Three-Age System in 1837.
Stone Age
The longest period in the history of science and technology, spanning over 3.4 million years, where stone was used to make tools with an edge or point.
Paleolithic Period
The "Old Stone" period and longest phase of human history where early humans were hunter-gatherers with no permanent dwellings.
Lower Paleolithic Period
Associated with Homohabilis and Homoerectus, characterized by simple stone tools like Acheulean handaxes and the controlled use of fire.
Middle Paleolithic Period
The period (ca 200,000 to 45,000 years ago) when Homosapiensneanderthalensis appeared and used Mousterian flake tools.
Upper Paleolithic Period
The period (40,000-10,000 years BP) marked by the disappearance of Neanderthals and the rise of modern humans with advanced tools and cave art.
Mesolithic Period
The "Middle Stone" period characterized by the use of microliths (small chipped stone tools) and the transition to semi-settled life.
Neolithic Period
The "New Stone" period linked with the Agricultural Revolution, including cereal cultivation and animal domestication.
Bronze Age
A period (3000 BC – 1200 BC) marked by the introduction of metals produced through smelting ores like copper and tin.
Iron Age
The last period of the Ancient Age (1500 BC – 450 AD) when tools and weapons were made of iron and steel.
Smelting
The process of extracting metal from ores, which are rocks containing traces of different metals.
Steel
An alloy of iron and carbon that replaced bronze tools due to its abundance and strength.
Agricultural Revolution
A shift from foraging to agriculture where people learned to plant crops and raise animals as resources became scarce.
Ionian School of Philosophy
A Pre-Socratic group of Greek philosophers in the 5th-6th century BC who studied the origins of the universe.

Socrates' method of enquiry used to highlight incorrect thinking by citizens and serve as a building block for scientific research.
