Fundamental interaction and the strong interaction. Their magnitude and behaviour vary greatly, as described in the table below. Modern physics attempts to explain every observed physical phenomenon by these fundamental interactions. Moreover, reducing the number of different interaction types is seen as desirable. Two cases in point are the unification of: Both magnitude ("relative strength") and "range", as given in the table, are meaningful only within a rather complex theoretical framework. It should also be noted that the table below lists properties of a conceptual scheme that is still the subject of ongoing research. The modern (perturbative) quantum mechanical view of the
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.
