The web page traces the history of nuclear fission from the discovery of radioactivity by Becquerel and the Curies to the Nobel Prize-winning work of Hahn, Meitner, Strassmann and Frisch in 1938. It also explains the mechanism, applications and background of fission, and the role of neutrons, isotopes and elements in the process.
Learn how nuclear power affects the environment, both positively and negatively, through various stages of the nuclear fuel cycle. Find out how nuclear power plants emit less greenhouse gases than fossil fuels, but also produce radioactive waste that requires long-term storage or disposal.
Learn how nuclear power was invented and developed from the discovery of fission to the first nuclear reactors and weapons. The web page covers the origins, the first nuclear reactor, the early years, and the current status of nuclear power.
So from Møller's remark the exciting vision arose that by assembling enough pure uranium (with appropriate care!) one might start a controlled chain reaction and liberate nuclear energy on a scale that really mattered. [22] The news of the discovery of fission was brought to America by Bohr in January 1939. [23]
Nuclear fission is a substantial part of the world’s energy mix, but out in the broader universe, fission is much harder to come by. Until now. Nuclear Fission Has Been Damn Near Impossible to ...
Learn how scientists discovered and understood the natural and human-caused causes of climate change since the 19th century. The web page covers the early observations of ice ages, the greenhouse effect, the first quantitative predictions of global warming, and the modern research and assessments.
Otto Hahn (1879-1968) was a Nobel laureate in chemistry who discovered radioactive isotopes, atomic recoil and nuclear fission. He worked with Lise Meitner and Fritz Strassmann on uranium and thorium, and was involved in the German nuclear weapons program during World War II.
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei, releasing large amounts of energy and neutrons. Learn about the discovery, mechanism, products, and uses of fission for nuclear power and weapons.
