Subrahmanyan Chandrasekhar Subrahmanyan Chandrasekhar, FRS (Tamil: சுப்பிரமணியன் சந்திரசேகர் ; ; 19 October 1910 – 21 August 1995), was an Indian American astrophysicist who was awarded the 1983 Nobel Prize for Physics with William A. Fowler "for his theoretical studies of the physical processes of importance to the structure and evolution of the stars". His mathematical treatment of stellar evolution yielded many of the best current theoretical models of the later evolutionary stages of massive stars and black holes. The Chandrasekhar limit is named after him.

List of Fritz London Memorial Prizes The Fritz London Memorial Prize was created to recognize scientists who made outstanding contributions to the advances of the field of Low Temperature Physics. It is traditionally awarded in the first session of the International Conference on Low Temperature Physics, which is sponsored by the International Union of Pure and Applied Physics. The prize is named in honor of Fritz London.

Complex beam parameter In optics, the complex beam parameter is a complex number that specifies the properties of a Gaussian beam at a particular point z along the axis of the beam. It is usually denoted by "q". It can be calculated from the beam's vacuum wavelength λ, the radius of curvature "R" of the phase front, the index of refraction "n" ("n"=1 for air), and the beam radius "w" (defined at 1/"e" intensity), according to:

G-factor (physics) A g"-factor (also called g" value or dimensionless magnetic moment) is a dimensionless quantity that characterizes the magnetic moment and gyromagnetic ratio of an atom, a particle or nucleus. It is essentially a proportionality constant that relates the observed magnetic moment "μ" of a particle to its angular momentum quantum number and a unit of magnetic moment, usually the Bohr magneton or nuclear magneton.

Scalar field In mathematics and physics, a scalar field associates a scalar value to every point in a space – possibly physical space. The scalar may either be a (dimensionless) mathematical number or a physical quantity. In a physical context, scalar fields are required to be independent of the choice of coordinate system, meaning that any two observers using the same units will agree on the value of the scalar field at the same absolute point in space (or spacetime) regardless of their respective points of origin. Examples used in physics include the temperature distribution throughout space, the pressure distribution in a fluid, and spin-zero quantum fields, such as the Higgs field. These fields are the subject of scalar field theory.

Lattice constant The lattice constant, or lattice parameter, refers to the physical dimension of unit cells in a crystal lattice. Lattices in three dimensions generally have three lattice constants, referred to as "a", "b", and "c". However, in the special case of cubic crystal structures, all of the constants are equal and we only refer to "a". Similarly, in hexagonal crystal structures, the "a" and "b" constants are equal, and we only refer to the "a" and "c" constants. A group of lattice constants could be referred to as lattice parameters. However, the full set of lattice parameters consist of the three lattice constants and the three angles between them.

Mach number In fluid dynamics, the Mach number (M or Ma) ( ; ] ) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound.

Bohr magneton In atomic physics, the Bohr magneton (symbol "μ") is a physical constant and the natural unit for expressing the magnetic moment of an electron caused by either its orbital or spin angular momentum.

Grassmann number In mathematical physics, a Grassmann number, named after Hermann Grassmann (also called an anticommuting number or supernumber), is an element of the exterior algebra over the complex numbers. The special case of a 1-dimensional algebra is known as a dual number. Grassmann numbers saw an early use in physics to express a path integral representation for fermionic fields, although they are now widely used as a foundation for superspace, on which supersymmetry is constructed.

Schoenflies notation The Schoenflies (or Schönflies) notation, named after the German mathematician Arthur Moritz Schoenflies, is one of two conventions commonly used to describe point groups. This notation is used in spectroscopy. The other convention is the Hermann–Mauguin notation, also known as the International notation. A point group in the Schoenflies convention is completely adequate to describe the symmetry of a molecule; this is sufficient for spectroscopy. The Hermann–Mauguin notation is able to describe the space group of a crystal lattice, while the Schoenflies notation isn't. Thus the Hermann–Mauguin notation is used in crystallography.

Scaling dimension In theoretical physics, scaling dimension, or simply dimension, of a local operator in a quantum field theory characterizes rescaling properties of the operator under spacetime dilations formula_1. If the quantum field theory is scale invariant, scaling dimensions of operators are fixed numbers, otherwise they are functions depending on the distance scale.
