While such symmetrical thinking is attractive for its simplicity, Lieberson (1985) has pointed out that not all causal relationships are governed by a symmetry principle
Perhaps the power of symmetry principles
to reveal nature's secrets has been drained, and a novel insight into how to pry secrets from nature awaits discovery.
4) For science to exist, certain conditions must hold and these restrictions, on the physical universe, are a direct consequence of the existence of symmetry principles
Writing for physicists working in molecular spectroscopy and quantum chemistry, Burenin (applied physics, Russian Academy of Sciences) systematically describes quantum intramolecular dynamics on the basis of the symmetry principles
Rather more serious, I think, is the somewhat surprising omission of relationship between PSR and symmetry principles
in physics, such as Curie's principle, symmetry breaking, gauge symmetry and so on.
In other words, elegant symmetry principles
specify what sort of dice were rolled to produce our world.
Established laws of particle physics, describing the quarks and leptons that make up matter and the bosons transmitting forces between them, are rooted in mathematical symmetry principles
