Bertrand Russell - lived from (18 May 1872 - 2 February 1970). He was renowned as a philosopher (1905 Essay " On Denoting

 "), As a mathematician (" Principia Mathematica

 (Links to an external site.)

 "- set of 3 volumes written with Alfred North Whitehead) and a Nobel Prize winner (1950 Nobel Prize in Literature). He is not the origin of the" Turtles all the way down story

Aristotle (340 BC) - lived from (384-322 BC). Aristotle was a Greek Philosopher and he founded the  Peripatetic School of Philosophy

  Around 335 BC. He is known as the father of western philosophy and influenced a lot of Christian and Islamic thought.

Ptolemy - Also know as Claudius Ptolemaeus was a Greek astronomer who lived from (c. AD 100 - c. 170). Ptolemy was most well know for his contributions on how the planets, sun, and moon moved in our solar system. Although, he did believed that the Earth was the center of the universe and everything rotated around the Earth.

Copernicus (1514) -  Nicolaus Copernicus lived and died in what was known as Royal Prussia part of Poland. He has lived from February 19, 1473, till May 24, 1543. He is most notably known for his Heliocentric Theory which stated the Sun was at the center of the Universe rather than the Earth. Copernicus had been working on his theory for some time but did not publish his work until his deathbed. He was said to have awoken from a coma “ looked at his book, and then died peacefully.”

Johannes Kepler - lived from (27 December, 1571 - 15 November, 1630), was a German mathematician, astronomer and astrologer best known for his laws of planetary motion, which provided foundation to Newton's theory of universal gravity. Kepler is one of the key figures in the 17th-century scientific revolution. 


Galileo Galilee (1609) - lived from (15 February 1564 - 8 January 1642). He was an Italian astronomer and physicist, primarily known for his large contributions to observational astronomy, physics, and modern science. Galileo is most known for his contributions to observational astronomy, including: the observation and study of Jupiter's moons, Kepler's supernova, telescopic studies of sunspots, and the study of the craters and mountains on our moon. 

Newton - lived from (12/25 / 1687– 3/20/1727). Newton was a very influential astronomer, physicist, and mathematician who was an important figure in the scientific revolution. Newton is most famously known for developing the laws of motion and universal gravitation as well as inventing calculus ( 

 ). In 1687, Newton published his book ( " Philosophiæ Naturalis Principia Mathematica


 " ) Which outlined his theories. Newton's laws of motion describe how bodies interact with the forces around it. Meanwhile, the law of universal gravitation can be described using this formula: where F = gravitational force, G = gravitational constant, m1 and m2 = mass of objects, and r = the distance between the center of the two masses
