Noether theorem (Noether):
A theorem which revels that symmetries are what gives increase to conserved quantities. For example, translational symmetry (the fact that the laws of physics work the similar in all places) gives increase to conservation of momentum, as position & momentum are complementary. In addition, conservation of energy is mention by time symmetry, & conservation of angular momentum is mentioned by isotropy.
Why rotation of rigid bodies through finite angles not a vector? Ans) Because it does not obey one of the laws of vector algebra(law of commutativity).
