Freeman Dyson, legendary theoretical physicist, dies at 96
Dyson helped create modern particle physics, criticized nuclear weapons tests, and imagined how civilizations could take to the stars.
Tell you what, if you can figure out the number of atoms in the sun when you are 5, you don't need a Ph.D.!Proud not to be a Ph.D.
Freeman John Dyson was born on December 15, 1923, in Crowthorne, England. His father was the prominent British composer Sir George Dyson, and his mother, Mildred Atkey, was a social worker. He was a math prodigy who by the age of 5 had calculated how many atoms were in the sun.
