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
The Theoretical Minimum was published in 2017. This covers Special Relativity and Classical Field Theory Lectures in the remaining three courses, on are available on-line as video recordings. Further lecture courses in the Theoretical Minimum series have been delivered by Prof. Susskind, on and these are also available on-line as video recordings. The Theoretical Minimum The Theoretical Minimum: What You Need to Know to Start Doing Physics () is a popular science book by Leonard Susskind and George Hrabovsky.
