Loading...Distinction without a difference
A fundamental idea of symmetry is that one can artificially create a distinction where no real difference exists. Spin a square and you’ve changed something, but nothing has changed. Amazing when you realize it applies to math, physical forces and well, god knows whatever else is out there.
Such a weird concept, transforming something so it’s the same – not everything can do that. Great vid here btw.
Ahh, yes,. the idea of symmetry – changing something but keeping it the same. Not an obvious feature of the universe until you get curious. Great site about it here https://devdude.me/blog/physSymmetries
Trust physicists to make a simple concept difficult.
