Ernest Rutherford, 1st Baron Rutherford of Nelson (30 August 1871 – 19 October 1937) was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. He has been described as "the father of nuclear physics", [7] and "the greatest experimentalist since Michael Faraday". [8]
On 8 November 2012, the LHCb team reported on an experiment seen as a "golden" test of supersymmetry theories in physics, [126] by measuring the very rare decay of the meson into two muons (+). The results, which match those predicted by the non-supersymmetrical Standard Model rather than the predictions of many branches of supersymmetry, show ...
Nuclear fusion is a reaction in which two or more atomic nuclei (for example, nuclei of hydrogen isotopes deuterium and tritium), combine to form one or more atomic nuclei and neutrons. The difference in mass between the reactants and products is manifested as either the release or absorption of energy .
For example, a quantum particle like an electron can be described by a wave function, which associates to each point in space a probability amplitude. Applying the Born rule to these amplitudes gives a probability density function for the position that the electron will be found to have when an experiment is performed to measure it. This is the ...
), an electron (e −) and an electron antineutrino (ν e) (see picture). This occurs when one of the down quarks in the neutron (u d d) decays into an up quark by emitting a virtual W − boson, transforming the neutron into a proton (u u d). The W − boson then decays into an electron and an electron antineutrino. [72]

There’s certainly nothing living on the asteroid Bennu, an airless, 1,614-ft. rubble pile orbiting the sun about 40.2 million miles from Earth. But that doesn’t mean that Bennu hasn’t all at ...
A variant of the Schrödinger's cat experiment, known as the quantum suicide machine, has been proposed by cosmologist Max Tegmark. It examines the Schrödinger's cat experiment from the point of view of the cat, and argues that by using this approach, one may be able to distinguish between the Copenhagen interpretation and many-worlds.
