But what really is symmetry? (Apparent vs. Actual Structure)

First post in a while: a fairly short one on some thoughts I had about symmetry. As I see it, symmetry is an artifact of us considering apparent instead of actual structures when analyzing systems. I talk about this and various examples. There are two other stories about symmetry I also hope to cover in the future that I have mentioned below the embedding

  • The Modern Definition of a Particle: Particles can be seen as simply representations of their spin and little group symmetries. In other words, we basically define a particle as some fundamental symmetry
  • Symmetry breaking: Symmetry breaking brings to center stage the ideas of order/disorder, emergence, and reductionism, the spiritual cores of physical thinking. For a wonderful look on this, refer to the seminal paper by Anderson: More is Different
