A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
In particle physics, the most important hierarchy problem is the question that asks why the weak force is 10 24 times as strong as gravity. [10] Both of these forces involve constants of nature, the Fermi constant for the weak force and the Newtonian constant of gravitation for gravity.
Miniaturization (publ. 1961) included Feynman's lecture as its final chapter "There's Plenty of Room at the Bottom: An Invitation to Enter a New Field of Physics" was a lecture given by physicist Richard Feynman at the annual American Physical Society meeting at Caltech on December 29, 1959. [1]
Longitudinal recording and perpendicular recording, two types of writing heads on a hard disk Magnetic storage or magnetic recording is the storage of data on a magnetized medium. Magnetic storage uses different patterns of magnetisation in a magnetizable material to store data and is a form of non-volatile memory .
No matter how many problems we solve, there will always be other problems that cannot be solved within the existing rules. […] Because of Gödel's theorem, physics is inexhaustible too. The laws of physics are a finite set of rules, and include the rules for doing mathematics, so that Gödel's theorem applies to them." [48]
