51Outline of physical science — Physical science is an encompassing term for the branches of natural science and science that study non living systems, in contrast to the life sciences. However, the term physical creates an unintended, somewhat arbitrary distinction, since many …
52Mathematics and Physical Sciences — ▪ 2003 Introduction Mathematics Mathematics in 2002 was marked by two discoveries in number theory. The first may have practical implications; the second satisfied a 150 year old curiosity. Computer scientist Manindra Agrawal of the… …
53Fine-structure constant — The fine structure constant or Sommerfeld fine structure constant, usually denoted alpha ,, is the fundamental physical constant characterizing the strength of the electromagnetic interaction.It is a dimensionless quantity, and thus its numerical …
54Dimensionless physical constant — In physics, a dimensionless physical constant (sometimes fundamental physical constant) is a universal physical constant that is dimensionless having no unit attached, so its numerical value is the same under all possible systems of units. The… …
55Crystal structure — In mineralogy and crystallography, crystal structure is a unique arrangement of atoms or molecules in a crystalline liquid or solid. A crystal structure is composed of a pattern, a set of atoms arranged in a particular way, and a lattice… …
56Constante De Structure Fine — Cet article fait partie de la série Mécanique quantique Postulats de la mécanique quantique Histo …
57Constante de structure fine — En physique, la constante de structure fine, représentée par la lettre grecque α, est une constante fondamentale qui régit la force électromagnétique assurant la cohérence des atomes et des molécules. Elle fut proposée en 1916 par le physicien… …
58Data structure alignment — is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding. When a modern computer reads from or writes to a memory address, it will do this in word sized …
