Particle physics — is a branch of physics that studies the elementary constituents of matter and radiation, and the interactions between them. It is also called high energy physics, because many elementary particles do not occur under normal circumstances in nature … Wikipedia
Many-worlds interpretation — The quantum mechanical Schrödinger s cat paradox according to the many worlds interpretation. In this interpretation every event is a branch point; the cat is both alive and dead, even before the box is opened, but the alive and dead cats are in… … Wikipedia
Particle in a box — In physics, the particle in a box (also known as the infinite potential well or the infinite square well) is a problem consisting of a single particle inside of an infinitely deep potential well, from which it cannot escape, and which loses no… … Wikipedia
State (physics) — In physics,the term state is used in several related senses,each of which expresses something about the way a physical system is.# State is sometimes used as a synonym for phase of matter. #In classical mechanics state of a system (or body)… … Wikipedia

Particle in a spherically symmetric potential — In quantum mechanics, the particle in a spherically symmetric potential describes the dynamics of a particle in a potential which has spherical symmetry. The Hamiltonian for such a system has the form:hat{H} = frac{hat{p}^2}{2m 0} + V(r)where m 0 … Wikipedia
Particle physics and representation theory — There is a natural connection, first discovered by Eugene Wigner, between the properties of particles, the representation theory of Lie groups and Lie algebras, and the symmetries of the universe. According to it, the different states of an… … Wikipedia
Many-minds interpretation — The many minds interpretation of quantum mechanics extends the many worlds interpretation by proposing that the distinction between worlds should be made at the level of the mind of an individual observer. The concept was first introduced in 1970 … Wikipedia
