Quantum it describes a fundamental aspect of energy not just restricted to photons. In the attempt to bring theory into agreement with experiment, Max Planck postulated that electromagnetic energy is absorbed or emitted in discrete packets, or quanta. Quantum In physics, a quantum (plural: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property may be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example,
Bulletin of the Lebedev Physics Institute Bulletin of the Lebedev Physics Institute Bulletin of the Lebedev Physics Institute (Russian: "Краткие сообщения по физике", "Kratkue Soobsheniya po fisike") is a peer-reviewed scientific journal of physics. The journal was established in 1970, and is published by the Lebedev Physical Institute (in Russian) a monthly basis. Springer publishes an English translation of the journal. It is edited by Oleg N. Krokhin. The online version is available since 2007. The "Bulletin" covers research results from Prokhorov General Physics Institute and the Institute for Nuclear Research of the Russian Academy of Sciences in addition to those of the Lebedev Physical Institute.
