It is concerned with procedures such as ionization and excitation by photons or collisions with atomic particles.
What "atomic" doesn't do is make any ensures about thread protection. If thread A is calling the getter concurrently with thread B and C calling the setter with distinctive values, thread A might get any among the list of a few values returned -- the 1 just before any setters becoming named or both of your values handed into the setters in B and C. Similarly, the item may well end up having the worth from B or C, no way to tell.

(1687), proposed that Boyle’s legislation, which states the products of the stress and the amount of a gasoline is consistent at the exact same temperature, could be defined if a single assumes the gas is composed of particles. In 1808 the English chemist John Dalton recommended that each component includes identical atoms, and in 1811 the Italian physicist Amedeo Avogadro hypothesized which the particles of features may perhaps encompass two or maybe more atoms caught collectively.
