Preparation (physics) experienced in quantum mechanics. Preparation (physics) Generally, measuring instruments are meant to get the (pre-)existent value of a physical quantity of a system with as little change of, or interaction with the system as possible. — If a measuring instrument fixes a physical quantity of a physical system for further use (post-existent), then the measurement process is called preparation. For example, a graduated cylinder filled to a definite mark prepares a certain volume of the liquid for further use. Though preparation measures a physical quantity — at least by fixing it — it often destroys previous states of the physical
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.
