Quantum scale invariance is a fundamental concept in theoretical physics, particularly in quantum field theory. It's a fancy term for "things don't change much, but they do change." - A Physicist
There are two types of quantum scale invariance:
This is the boring, but mathematically rigorous one. Don't get too excited.
This is where things get weird, but not too weird.

You should care because understanding quantum scale invariance can help you navigate the intricacies of quantum mechanics, or at least make you sound smart in cocktail parties.
