So, all of the generators of the Poincare group are associated with pretty well-known physical quantities. Time translation is associated with energy, space translations with momentum, rotations with angular momentum, and boosts... well, boosts are generated by the "generators of boosts". Do...

If one assumes that the universe is deterministic (i.e. the configuration of the universe is a single one), then all of the results of all experiments are determinate. That means that all future measurements have a single, definite outcome. Being humans, we have the limitation of only...

So, an usual introduction to Quantum Mechanics (like the one given by Sakurai) is to refer to sequential Stern-Gerlach (SG) experiments. For example, a first one aligned to the z axis, a second one aligned to the x axis, and a third one aligned to the z axis again (with no relevant dynamical...
