| Symmetries: Symmetry is an expression for the invariance of properties that are subjected to transformation such as mirroring, rotation, or displacement or repetition. Applied to theories and systems, the presence of symmetries makes greater simplicity possible._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. | |||

Bernulf Kanitscheider on Symmetries - Dictionary of Arguments
I 277 Symmetries/Kanitscheider: electromagnetic interaction: quantum electrodynamics, symmetry U(1), Strong Interaction: Quantum Chromodynamics, Symmetry of Color SU(3) Weak WW: Group SU(2) First unification step: Salam/Weinberg: gauge theory with the group structure SU(2)xU(1) Georgi/Glashow: (1974) 'Unification of the electroweak with the strong interaction: GUT/Great Unifying Theory: fundamental symmetry SU(5), which as a subgroup is the product of the three original forces SU(3)cxSU(2)xU(1) with included. I 276 Symmetry breaking/Kanitscheider: the spontaneous symmetry breaking occurs when the symmetric solution is unstable with a symmetric basic law. This transitions the system into an asymmetric state that obscures the original symmetry of the law. A broken symmetry is epistemically a hidden symmetry. I 279 Symmetry/Kanitscheider: a completely isotropic liquid can become anisotropic because of its crystalline character. Permanent magnets lose the common alignment of all elemental north and south poles when heated. In general, a system has higher symmetries at high temperatures than at lower ones. _____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
