SUMMARY:Colloquium: Klaus Mainzer (Technische Universität München) "Symme
 try in Physics"
TZID:Europe/London
UID:20230315-8a17841a837f52ba01838e24175e70b5@warwick.ac.uk

DESCRIPTION:In the history of science\, culture\, and arts\, symmetries h
 ave been used as fundamental models of order. This raises the question o
 f whether they were merely invented by humans to order the diversity of 
 phenomena\, whether they even arise only from an aesthetic need\, or whe
 ther they are basic structures of nature that exist independently of hum
 ans. In antiquity\, at any rate\, knowledge\, arts\, and nature were und
 erstood from a common symmetrical basic order. In this talk\, the basic 
 mathematical conceps of symmetry are first explained with illustrative e
 xamples up to the group-theoretical methods. On this basis\, fundamental
  principles of physics such as the conservation laws\, time\, space\, an
 d charge invariance (CPT theorem)\, and space-time structures are introd
 uced with symmetries. In the standard model of elementary particle physi
 cs\, local gauge symmetries are used to characterise the fundamental for
 ces in the quantum world. Symmetry breaking occurs\, which is also used 
 to explain the expansion of the universe. Molecular symmetry breaking (c
 hirality) is at the beginning of biological evolution. In addition to ma
 thematical models\, measurement and experiment have been decisive in dec
 iding questions of symmetry in nature since Galileo's time. Today\, the 
 technical effort required for this is enormous and ranges from the labor
 atories of high-energy physics to observatories and satellites. Symmetry
  and symmetry breaking are proving to be complementary research principl
 es for explaining the emergence of diversity and complexity in nature. R
