July 16, 1945, marked a turning point in history with the first nuclear test, named Trinity, in the New Mexico desert in the ...

Their former colleague Lise Meitner, who a few months before had been forced to flee Germany and seek refuge in Sweden, and her nephew Otto Frisch realized that the uranium nucleus had split in two.

T here is a fairly popular idea circulating the Internet that a single gram of uranium contains about 20 billion calories, with some joking that eating it could sustain you like a turbo-charged diet ...

O. Hahn and F. Strassmann 1 have discovered a new type of nuclear reaction, the splitting into two smaller nuclei of the nuclei of uranium and thorium under neutron bombardment. Thus they ...

Since the first nuclear explosion in history during the Trinity test in 1945, nuclear weapons have significantly shaped the ...

Uranium is the primary fuel for nuclear reactors and must be managed properly, in a safe and sustainable manner. Recent annual production of natural uranium world-wide has been between 55,000 and ...

In ordinary water, each hydrogen atom has just a single proton in its nucleus. In heavy water ... harness the energy of countless atoms of uranium splitting apart, or fissioning, in a chain ...

a few of the neutrons bombarding the uranium nucleus should cause it to fission and the telltale outcome would be a small but measurable amount of the element barium. After an hour, Jim switched ...

The relative mass of a nucleus is the number of protons and neutrons ... but before the neutrons can collide with fresh uranium nuclei, they need to be slowed down.

Nuclear fission – the physical process by which very large atoms like uranium split into pairs of smaller atoms – is what makes nuclear bombs and nuclear power plants possible. But for many years, ...
