Science, as we now think of it, only really started about 400 years ago when Francis Bacon unified theory, observation, and experiment in his: “A New Method.” Before this “unified procedure,” science was a patchwork of “lucky guesses” which over-emphasized one tool or another (For example, Aristotle loved reason and hated mathematics whereas Pythagoras believed the world could only be described by pure mathematics).

In addition, quantitative experimentation and the idea of “testing a hypothesis,” only really became practically feasible with inventions of the early Renaissance. Below we give more detail on some these key milestones in the advancement of research, physics, chemistry and biology.

RESEARCH:

Civilization, Writing: The most basic pre-requisite for science is an organized society which allows/requires an “intellectual class” in order to function (e.g. basic arithmetic and writing are required for basic trading and taxes)

The most basic pre-requisite for science is an organized society which allows/requires an “intellectual class” in order to function (e.g. basic arithmetic and writing are required for basic trading and taxes) Universities, Paper Mills: Science didn’t advance much from 300 BC to 1300 AD for several reasons including Roman distaste for philosophy, academic focus on theology, etc. However, the establishment of the first universities, in the early 13th century, set the foundation for later innovations of the Renaissance by enabling communication and collaboration between a growing number of “intellectual aristocrats.”

PHYSICS:

Simple Math, Machines: Greece, in particular, set much of the ancient foundation of physics in the form of qualitative mechanical principles and basic mathematical theories

Mechanics/Optics/Gravity: Isaac Newton unified and quantitatively defined mechanics, gravity and optics through rigorous experimentation and the invention of calculus.

Electromagnetic Theory: The unification of electronic and magnetic forces by Maxwell’s equations set the foundation for electrical engineering and virtually every analytical tool later used by physicists, chemists and biologists (e.g. computers, spectroscopy, electrophoresis, etc.)

CHEMISTRY:

Metallury, Oils: Early chemistry was a patchwork of metallurgy, oil extraction (pioneered by the Egyptians for embalming) and Aristotle’s ideas (e.g. water is an element).

Early chemistry was a patchwork of metallurgy, oil extraction (pioneered by the Egyptians for embalming) and Aristotle’s ideas (e.g. water is an element). Venetian glassware, thermometer/barometer: Most early chemistry relied on the ability to manipulate and dissect gasses while measuring pressure, temperature and weight. All of this relied on specialized glassware developed by Venetian glass-makers during the 13th through 16th centuries

Atomic Theory: John Dalton went further to show that compounds were made up of integer ratios of elements which lead to his atomic theory of chemistry.

Later chemists, such as Gilbert Lewis built off of this atomic theory by proposing that chemical bonds could be pairs of shared electrons Hybridization: Finally, chemists like Linus Pauling, built up a quantum mechanical view of chemical bonds and chemical properties which is the basis of how chemists understand chemistry today.

BIOLOGY:

Anatomy, Breeding: The foundations of modern biology were driven by very practical and primal innovations such as the domestication of animals (50-20,000BC), early agriculture (8,000 BC) and surgery/anatomy (200 AD).

Microscope: The invention of the microscope by Galileo (and refined by Robert Hooke and Antonie Philips van Leeuwenhoek) opened up the microscopic world showing that it followed similar rules as the macroscopic world.

Chemical Life: Chemistry and Biology were unified in the first half of the 20th century through the demonstration that all life consisted of chemical building blocks and chemical and mechanical processes.
