Acta Physica Sinica (abbreviation: Acta. Phys. Sin., or also APS) is a peer-reviewed scientific journal in the fields of physics published by the Chinese Physical Society. Established in 1933 as Chinese Journal of Physics , the journal was published in English, French and German at first.
The journal was established in 1992 as Acta Physica Sinica (Overseas Edition), publishing papers different from those of "Acta Physica Sinica" (in Chinese) in both language and content. The journal title was changed to Chinese Physics in 2000, and changed to Chinese Physics B in 2008.
Acta Physica may refer to several scientific journals of physics: Acta Physica Hungarica; Acta Physica Polonica;

The Chinese Journal of Physics is a bimonthly peer-reviewed scientific journal covering all aspects of physics. It is published by Elsevier on behalf of the Physical Society of Taiwan . [ 1 ] [ 2 ] The journal publishes reviews, articles, and refereed conference papers in all the major areas of physics.
In crystallography, materials science and metallurgy, Vegard's law is an empirical finding (heuristic approach) resembling the rule of mixtures.In 1921, Lars Vegard discovered that the lattice parameter of a solid solution of two constituents is approximately a weighted mean of the two constituents' lattice parameters at the same temperature: [1] [2]
Journal de Chimie Physique (JCP) was a peer-reviewed scientific journal of physical chemistry.It appeared between 1903 until 1999. At the end of the journal's life, it was published by EDP Sciences, who was that the end of the journal was a "part of a general trend to replace national publications with international (European) ones to better compete with American publications."
Ptolemy's theorem states that the sum of the products of the lengths of opposite sides is equal to the product of the lengths of the diagonals. When those side-lengths are expressed in terms of the sin and cos values shown in the figure above, this yields the angle sum trigonometric identity for sine: sin(α + β) = sin α cos β + cos α sin β.
