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
Nepal Physical Society basis. Previously, the office of the society was situated in Tri-Chandra College, Ghantaghar, Kathmandu, Nepal. Currently, the office is in the Central Department of Physics, Tribhuvan University, Kirtipur, Nepal. Nepal Physical Society participated in the 38th International Physics Olympiad in 2007. Nepal Physical Society Nepal Physical Society (NPS) is a professional society of the Nepalese physicists. The small society of about 500 members was established in 1982. To be eligible for membership, one has to hold a minimum of a master's degree in physical science from either Tribhuvan University or another university that is recognized by Tribhuvan University.
