Szilard in a sentence

Einstein had signed a letter to President Franklin Delano Roosevelt, written by physicist Leo Szilard, that urged the development of a fission bomb in 1939.

After Adolf Hitler became chancellor of Germany in 1933, Szilard urged his family and friends to flee Europe while they still could.

As such, it established Szilard as one of the founders of information theory, but he did not publish it until 1929, and did not pursue it further.

Foreseeing another war in Europe, Szilard moved to the United States in 1938, where he worked with Enrico Fermi and Walter Zinn on means of creating a nuclear chain reaction.

He drafted the Szilard petition advocating a demonstration of the atomic bomb, but the Interim Committee chose to use them against cities without warning.

In 1946, Szilard secured a research professorship at the University of Chicago that allowed him to dabble in biology and the social sciences.

In addition to the nuclear reactor, Szilard submitted patent applications for a linear accelerator in 1928, and a cyclotron in 1929.

In response to Szilard's petition, Teller consulted his friend Robert J. Oppenheimer.

In the summer, Fermi and Szilard proposed the idea of a nuclear reactor (pile) to mediate this process.

It was a field that Szilard had been working on in 1933 before he had become subsumed in the quest for a nuclear chain reaction.sfn The duo made considerable advances.

Nuclear chain reactions main A nuclear chain reaction was proposed by Leo Szilard in 1933, shortly after the neutron was discovered, yet more than five years before nuclear fission was first discovered.

Szilard had this idea while walking in London, on the same day.

Szilard persuaded Fermi and Herbert L. Anderson to try a larger experiment using convert of uranium.

Szilard stepped off the curb.

The results suggested the possibility of building nuclear reactors (first called "neutronic reactors" by Szilard and Fermi) and even nuclear bombs.

This introduced the thought experiment now called the Szilard engine and became important in the history of attempts to understand Maxwell's demon.

Thus to slow down the secondary neutrons released by the fissioning uranium nuclei, Fermi and Szilard proposed a graphite "moderator," against which the fast, high-energy secondary neutrons would collide, effectively slowing them down.

When Szilard told the story later he never mentioned his destination that morning.
