Famous Physicists as Children

From left to right: 

Stephen Hawking (b. 1942) - Most well known for Hawking radiation and theorems involving gravitational singularities. He suffers from ALS, also known as Lou Gehrig’s disease - and is one of the most well known scientists of our time. 

Neil deGrasse Tyson (b. 1958) - Currently the director of the Hayden Planetarium at the Rose Center for Earth and Space, Tyson is one of the leading science advocates in the world - and was one of the men who supported the demotion of Pluto.  

Carl Sagan (1934-1996) - One of the most successful science popularizers of all time, Sagan was also the bestselling author of Cosmos, one of the most popular science books of all time. He was the first to propose that Jupiter’s moons Titan and Europa may hold liquid components of water on them. 

Albert Einstein (1879-1955) - The most well known genius in history, Albert Einstein was a boss. During his career, he revolutionized almost every area of Physics, including quantum mechanics and he effectively founded the study of Cosmology. His theory of general relativity has been wildly successful, despite ‘attacks’ by neutrinos. 

Richard Feynman (1918-1988) - His most important contributions came via his path integral formulation of quantum mechanics and development of Quantum Electrodynamics (QED). Plus, he was a total badass.
