Eratosthenes
As many believed, the earth was flat. Eratosthenes proved them all wrong, or at least tried to. He used the distance from the sun to measure the entire Earth. The measurements he ended up with were shocking to the majority of whom doubted him. This discovery was influential to future generations and theories to be formed. -
90 BCE
Claudius Ptolemy
Ptolemy created a model of the solar system, all in which were explained were the sun, stars and planets revolves around Earth. His predictions were wrong unfortunately but that never stopped him from expanding his knowledge further. Soon to publish the “Almagest” a treatise on the coordination of stars and planets. The system shown all pre-existing of planetary locations. These official writings were around almost 1200 years after written. Very progressive and allows other to understand. -

Nicolaus Copernicus
Nicolaus created a visible model of the solar system where the Earth was orbiting around the Sun. Although, the model he presented wasn’t correct according to NASA, He wrote his own book establishing the study of how Earth in gravity/space works. He mentioned the intermittent retrograde of planets at which they move in opposite directions in space. This was an important discovery - finding because researchers had common questions with Copernicus. His book shared valuable descriptions. -
Tycho Brache
Tycho - with the use of instruments he created himself! He found out a way to measure one minute in arc. He knew Earth was at rest when the sun began to orbit around Earth and planets as well. The progressive era after this goal was beyond! A new way to measure longer times around Earth’s axis. -
Johannes Kepler
Both Tycho Brache, a previous astronomer mentioned and Johannes Kepler were on the same wavelength in studies. Kepler created 3 separate laws with sorting the motions of planets, and how planets travel in a elliptical orbit. But soon disregarded to believe that planets do not a travel at the same constant rate through their individual orbits. Kepler law was rein-formed in his decade of work, he worked with other astronomers to have a civili agreement to his discussion. -
Sir Isaac Newton
Another astronomer who conducted 3 laws for the motion of forces between objects. Law 1 was - Objects stay at rest until manipulated. 2 - Net force is equal to the rate at change is linear. 3 - every action has and equal and opposite attraction. Newton’s process was developed over time and tested on multiple methods to insure this process is adequate for others to test. This is an influential method because gravity is everywhere and can’t be changed without a form of manipulation as mentioned. -
Albert Einstein
Albert Einstein was an infamous scientist we all know and love! He proposed the laws of psychics are identical throughout all of history! Speed is constant no matter what being conducted. Also, both speed and time are relayed by “ space-time “ and is distorted by gravity. Einstein made an impeccable mark on today’s world of science. Researchers and other profound professionals sought out ideas through Einstein’s creativity and assortment of trial & error.
