The Evolution of Scientific Method: From Ancient Theories to Modern Discoveries
TLDR Before the scientific method, ancient theories such as the four humors of medicine and the Earth being the center of the universe were believed. However, through the discoveries of scientists like Kepler and the debunking of ideas like spontaneous generation, the scientific method emerged, leading to the advancement of knowledge and understanding in various fields.
Timestamped Summary
00:00
Before the scientific method, people believed in theories and practices such as the four humors of medicine, which were based on observations and philosophy rather than testing and evidence.
05:00
Before the scientific method, people believed in the four humors of medicine, which were fluids in the body associated with different states of health and energy, and the treatment for imbalances was to use the opposite qualities.
10:03
Eudoxus of Nidos believed that the Earth is the center of the universe and that all celestial motion is circular and regular, with the center of all celestial motion being the center of the universe.
14:57
Kepler discovered that celestial motion is not circular but elliptical, laying the groundwork for astrophysics.
19:59
The Pythagoreans believed that the Earth and all celestial bodies circled a central fire, including a hypothetical counter earth, and that each celestial body had its own circular orbit, with the counter earth explaining lunar eclipses.
24:57
Astrophysicists have determined that there is no counter earth affecting the orbits of other planets, debunking the idea of a central fire and counter earth.
29:41
Democritus introduced the idea of elements and attractive forces, and also predicted atomic theory by proposing the existence of indivisible and eternal atoms in a vacuum.
34:27
Aristotle rejected the idea of atoms moving in a void and instead believed that everything is connected, which delayed the acceptance of Democritus' accurate prediction of atomic theory for about two thousand years until Evangelista Torricelli created a vacuum and showed that air has weight, leading to the investigation into atomic theory.
39:41
Spontaneous generation was an ancient way of explaining where life came from, but it was disproved before the microscope by Francesco Redi, and later experiments with sterilized flasks of water were criticized until Louis Pasteur provided a precise method of sterilization.
44:40
Life arises from life and does not spontaneously generate, with Aristotle's theory of epigenesis being more accurate than pre-formationism, and the debunking of spontaneous generation by Francesco Redi and Louis Pasteur.
