2T-symmetry — is the symmetry of physical laws under a time reversal transformation mdash;: T: t mapsto t.Although in restricted contexts one may find this symmetry, the universe itself does not show symmetry under time reversal. This is due to the uncertainty …

4Parity (physics) — Flavour in particle physics Flavour quantum numbers: Isospin: I or I3 Charm: C Strangeness: S Topness: T Bottomness: B′ Related quantum numbers: Baryon number: B Lepton number: L Weak isospin: T or T3 Electric charge: Q …
5Scale space — theory is a framework for multi scale signal representation developed by the computer vision, image processing and signal processing communities with complementary motivations from physics and biological vision. It is a formal theory for handling …
6Scalar field theory — In theoretical physics, scalar field theory can refer to a classical or quantum theory of scalar fields. A field which is invariant under any Lorentz transformation is called a scalar , in contrast to a vector or tensor field. The quanta of the… …
7physical science, principles of — Introduction the procedures and concepts employed by those who study the inorganic world. physical science, like all the natural sciences, is concerned with describing and relating to one another those experiences of the surrounding… …
8Hughes–Drever experiment — Hughes–Drever experiments (also clock comparison , clock anisotropy , mass isotropy , or energy isotropy experiments) are testing the isotropy of mass and space. As in Michelson–Morley experiments, the existence of a preferred frame of reference …
9Speech repetition — Children copy with their own mouths the words spoken by the mouths of those around them. This enables them to learn the pronunciation of words not already in their vocabulary. Speech repetition is the saying by one individual of the spoken… …
10CPT symmetry — CPT theorem redirects here. For the album by Greydon Square, see The C.P.T. Theorem (album). CPT symmetry is a fundamental symmetry of physical laws under transformations that involve the inversions of charge, parity, and time simultaneously.… …
