[9] [10] [11] amplitude The height of a wave as measured from its center (normal) position. angle of incidence In geometric optics, the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic, microwave, X-ray, etc.
In atomic physics, spin–orbit coupling, also known as spin-pairing, describes a weak magnetic interaction, or coupling, of the particle spin and the orbital motion of this particle, e.g. the electron spin and its motion around an atomic nucleus. One of its effects is to separate the energy of internal states of the atom, e.g. spin-aligned and ...
In Australia, following the 2010 federal election, the Gillard government formed a minority government with the support of a number of votes from minor parties and independents, and the Opposition refused to grant automatic pairing, [2] [3] leading to some embarrassment and reversals for the Opposition when, for example, a pair was initially not given for a member to care for her sick baby [4 ...
In chemistry and physics, the exchange interaction is a quantum mechanical constraint on the states of indistinguishable particles.While sometimes called an exchange force, or, in the case of fermions, Pauli repulsion, its consequences cannot always be predicted based on classical ideas of force.

Bobby Allison, NASCAR Hall of Famer, has died at the age of 86, the auto racing body announced Saturday.. Allison died peacefully at his home in Mooresville, North Carolina, according to NASCAR.
In addition, groups 8, 9 and 10 used to be treated as one triple-sized group, known collectively in both notations as group VIII. In 1988, the new IUPAC (International Union of Pure and Applied Chemistry) naming system (1–18) was put into use, and the old group names (I–VIII) were deprecated.
Beau Shroyer and his wife moved to Angola to serve as long-term missionaries through the organization SIM. In a statement, SIM said it was "heartbroken" to learn of Beau Shroyer's death and was ...
