As a gifted educator he trained many of the physicists who developed quantum theory and its applications |

Roosevelt re. German capability to develop Atom Bomb. The letter was drafted by Eugene Wigner and Leo Szilard and delivered to Roosevelt by Dr. Alenander Sachs, a Lehman Bros. partner and prominent Democrat. 4/18/1955, Died, Princeton, NJ Einstein is the most renowned physicist of the 20th century and arguably one of the two most important physicists in history. At the age of 26, in 1905 while working at the Swiss patent office he produced two papers that were some of the most important and creative advances in the field, one dealing with quantum theory and the other developing special relativity. Ten years later, he added to this incredible output of creative thought the theory of general relativity. No physicist has ever made such a number of groundbreaking advances in his lifetime. Einstein worked alone and built no school around him. After 1924 he made no other significant contributions, and spent much of his time until death attempting to construct a unified theory that combined general relativity and quantum theory. Although he was conversant with quantum theory and indeed made contributions to its advancement, because of the statistical nature of the theory, he felt it was just an approximation and not the final theory that was yet to be found. |
