What is often said in Covariant LQG is that the triangulation is a truncation, and is not what is responsible for the discrete volumes one ends up with in the theory. Rather, what is responsible is the discrete spectra of the volume operator acting on the nodes of a spin network.
My confusion...
From Undergrad, most memorable would be:
- That magnetism can be understood as charges + length contraction
- The principle of "least" action
- Dirac quantisation (before knowing some representation theory, it does look like magic..)
- The gauge principle
Hi!
I'm looking for movies that have surreal physics. E.g. action movies with severe violation of conservation of momentum, scifi movies with "quantum" stuff in the plot ..etc.
What are your favorites?
