The 10 Greatest Physicists in  History

Anaximander  (Lived c. 610 BC – c. 546 BC.) Anaximander is responsible for the idea that the earth needs nothing below it to support it. He said that the earth floats in the center of infinity, held in position because it is an equal distance from all the other parts of the universe. 

Archimedes (Lived c. 287 BC – 212 BC.) He created the physical sciences of mechanics and hydrostatics, discovered the laws of levers and pulleys, and discovered one of the most important concepts in physics – the center of gravity. 

Galileo Galilei (Lived 1564 – 1642.) He was the first person to discover moons orbiting another planet, discovering Jupiter’s four largest moons. He discovered that Venus has phases like our moon 

Johannes Kepler (Lived 1571 to 1630.) Johannes Kepler broke the tradition of thousands of years of astronomy, discovering that the heavenly bodies follow elliptical paths. Kepler’s laws of planetary motion were an absolutely crucial breakthrough in our understanding of the universe.  

Isaac Newton (Lived 1643 to 1727) Isaac Newton invented calculus, the mathematics of change, without which we could not understand the behavior of objects as tiny as electrons or as large as galaxies.  

Michael Faraday (Lived 1791 to 1867.) Michael Faraday is probably the greatest experimental physicist ever. By varying a magnetic field he produced electric current in a wire, and so discovered electromagnetic induction, the means by which nearly all electricity is generated by power plants today.  

James Clerk Maxwell (Lived 1831 – 1879) He unified the electric and magnetic forces, showing that they are fundamentally the same force. His equations showed that when electric charges accelerate they release waves of electromagnetism traveling at the speed of light .

Ernest Rutherford (Lived 1871 – 1937) Ernest Rutherford is the father of nuclear chemistry and nuclear physics. He discovered and named the atomic nucleus, the proton, the alpha particle, the beta particle, and he predicted the existence of the neutron.  

Albert Einstein (Lived 1879 – 1955) Albert Einstein rewrote the laws of nature. He completely changed the way we understand the behavior of things as basic as light, gravity, space and time. He established that everyone, whatever their own speed relative to light, measures the speed of light to be 300 million meters per second in a vacuum.  

Niels Bohr (Lived 1885 – 1962) Niels Bohr completely transformed our view of the atom and of the world. Realizing that classical physics fails catastrophically when things are atom-sized or smaller, he remodeled the atom so electrons occupied ‘allowed’ orbits around the nucleus while all other orbits were forbidden.
