51Non-topological soliton — In quantum field theory, a non topological soliton (NTS) is a field configuration possessing, contrary to a topological one, a conserved Noether charge and stable against transformation into usual particles of this field for the following reason …
52Phase transition — This diagram shows the nomenclature for the different phase transitions. A phase transition is the transformation of a thermodynamic system from one phase or state of matter to another. A phase of a thermodynamic system and the states of matter… …
53Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
54Crystallography — For the book of poetry, see Crystallography (book). A crystalline solid: atomic resolution image of strontium titanate. Brighter atoms are Sr and darker ones are Ti. Crystallography is the experimental science of the arrangement of atoms in… …
55Loschmidt's paradox — Loschmidt s paradox, also known as the reversibility paradox, is the objection that it should not be possible to deduce an irreversible process from time symmetric dynamics. This puts the time reversal symmetry of (almost) all known low level… …
56String theory — This article is about the branch of theoretical physics. For other uses, see String theory (disambiguation). String theory …
57Pion — This article is about the subatomic particles. For the self propelled gun, see 2S7 Pion. Pion The quark structure of the pion. Composition π …
58Magnetic monopole — It is impossible to make magnetic monopoles from a bar magnet. If a bar magnet is cut in half, it is not the case that one half has the north pole and the other half has the south pole. Inst …
59Starfish — For other uses, see Starfish (disambiguation). Asteroidea redirects here. For the Asteraceae subfamily, see Asteroideae. Sea Stars Temporal range: Ordovician–Recent …
60Petrography — is that branch of petrology which focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail. Petrographic… …
