Hartland Snyder

From Wikipedia, the free encyclopedia

Hartland Snyder (1913-1962) was a physicist who along with Robert Oppenheimer calculated the gravitational collapse of a pressure-free homogenous fluid sphere and found that it cut it self off from communicating with the rest of the universe.

In 1955 he won a bet against Maurice Goldhaber where he said antiprotons existed and Goldhaber disagreed.

Hartland with M. Stanley Livingston and Ernest Courant developed the princple of strong focusing that allowed the development of modern particle accelerators. In "The Theory of the Alternating-Gradient Synchrotron" (Annals of Physics, Volume 281, Number 1, 10 April 2000 , pp. 360-408(49)) Courant and Snyder laid the foundations for the field of accelerator physics.
