The Emergency Committee of Atomic Scientists (ECAS) was founded by Albert Einstein and Leó Szilárd in May, 1946, primarily as a fundraising and policy-making agency. [1] Its aims were to warn the public of the dangers associated with the development of nuclear weapons, promote the peaceful use of nuclear energy, and ultimately work towards world peace, which was seen as the only way that ...
The Joe-1 atomic bomb test by the Soviet Union that took place in August 1949 came earlier than expected by Americans, and over the next several months there was an intense debate within the U.S. government, military, and scientific communities regarding whether to proceed with development of the far more powerful Super.

The Einstein-de Haas experiment is the only experiment concived, realized and published by Albert Einstein himself. A complete original version of the Einstein-de Haas experimental equipment was donated by Geertruida de Haas-Lorentz , wife of de Haas and daughter of Lorentz, to the Ampère Museum in Lyon France in 1961 where it is currently on ...
The Einstein–Szilard letter was a letter written by Leo Szilard and signed by Albert Einstein on August 2, 1939, that was sent to President of the United States Franklin D. Roosevelt. Written by Szilard in consultation with fellow Hungarian physicists Edward Teller and Eugene Wigner , the letter warned that Germany might develop atomic bombs ...
In December 1943, after a meeting with Albert Einstein, Bohr and his son Aage committed to working on the Manhattan Project. [67] Bohr made a substantial contribution to the atomic bomb development effort. [68] He also attempted to prevent a post-war atomic arms race with the Soviet Union, which he believed to be a serious threat.
Microsoft co-founder Paul Allen bought a copy of Einstein's infamous 1939 letter to Roosevelt in 2002. It just sold at auction for double what he paid. Einstein's 1939 letter, warning of atomic ...
The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 million tons of TNT (42 PJ). Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as 600 pounds (270 kg) can release energy equal to more than 1.2 ...
