The branch of astronomy that deals with the physics of the Universe, especially with the compositional nature of celestial bodies rather than their positions or motions in space. attenuation coefficient The measure of how much the incident energy beam (e.g. ultrasound or x-rays) is weakened by the material it is passing through. [19] atom
tesla meter (T⋅m) area: square meter (m 2) amplitude: meter: atomic mass number: unitless acceleration: meter per second squared (m/s 2) magnetic flux density also called the magnetic field density or magnetic induction tesla (T), or equivalently, weber per square meter (Wb/m 2)
The California Job Case was a compartmentalized box for printing in the 19th century, sizes corresponding to the commonality of letters. The frequency of letters in text has been studied for use in cryptanalysis, and frequency analysis in particular, dating back to the Arab mathematician al-Kindi (c. AD 801–873 ), who formally developed the method (the ciphers breakable by this technique go ...
Classical mechanics – Description of large objects' physics – study of motion of macroscopic objects. Climatology – Scientific study of climate, defined as weather conditions averaged over a period of time – study of climate. Clinology – study of aging or individual decline after maturity.

Just Words is a word game for one or two players where you scores points by making new words using singularly lettered tiles on a board, bringing you the classic SCRABBLE experience, but with a twist!
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
The word "wave function" could mean one of following: A vector in Hilbert space which can represent a state; synonymous to "ket" or "state vector". The state vector in a specific basis. It can be seen as a covariant vector in this case.
A-type star In the Harvard spectral classification system, a class of main-sequence star having spectra dominated by Balmer absorption lines of hydrogen. Stars of spectral class A are typically blue-white or white in color, measure between 1.4 and 2.1 times the mass of the Sun, and have surface temperatures of 7,600–10,000 kelvin.
