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 other cultures, especially Hinduism and Buddhism, many personification figures still retain their religious significance, which is why they are not covered here. For example, Bharat Mata was devised as a Hindu goddess figure to act as a national personification by intellectuals in the Indian independence movement from the 1870s, but now has ...
A national personification is an anthropomorphic personification of a state or the people(s) it inhabits. It may appear in political cartoons and propaganda . In the first personifications in the Western World , warrior deities or figures symbolizing wisdom were used (for example the goddess Athena in ancient Greece), to indicate the strength ...
In physics, there are equations in every field to relate physical quantities to each other and perform calculations. Entire handbooks of equations can only summarize most of the full subject, else are highly specialized within a certain field. Physics is derived of formulae only.
Other examples of anthropomorphism include the attribution of human traits to animals, especially domesticated pets such as dogs and cats. Examples of this include thinking a dog is smiling simply because it is showing his teeth, [50] or a cat mourns for a dead owner. [51] Anthropomorphism may be beneficial to the welfare of animals.
Upon writing the most general Lagrangian with massless neutrinos, one finds that the dynamics depend on 19 parameters, whose numerical values are established by experiment. Straightforward extensions of the Standard Model with massive neutrinos need 7 more parameters (3 masses and 4 PMNS matrix parameters) for a total of 26 parameters. [ 10 ]
