The proposal to use pulsars as gravitational wave (GW) detectors was originally made by Mikhail Sazhin [4] and Steven Detweiler [5] in the late 1970s. The idea is to treat the solar system barycenter and a galactic pulsar as opposite ends of an imaginary arm in space. The pulsar acts as the reference clock at one end of the arm sending out ...
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 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 chemistry and atomic physics, an electron shell may be thought of as an orbit that electrons follow around an atom's nucleus.The closest shell to the nucleus is called the "1 shell" (also called the "K shell"), followed by the "2 shell" (or "L shell"), then the "3 shell" (or "M shell"), and so on further and further from the nucleus.

President-elect Trump said Democrats made a “BIG mistake” getting involved with former Rep. Liz Cheney (R-Wyo.) and her father, former Vice President Dick Cheney. “The Democrats made a BIG ...
Ligand-Field scheme summarizing σ-bonding in the octahedral complex [Ti(H 2 O) 6] 3+. In molecular symmetry terms, the six lone-pair orbitals from the ligands (one from each ligand) form six symmetry-adapted linear combinations (SALCs) of orbitals, also sometimes called ligand group orbitals (LGOs).
