I like this class as students are freely asking question. That is very rare these days.

The lectures are GOLD!! But the poor poor camera work is so disturbing.

23.00 I think superposition not only means that the particle is in some mixed-up states of basis but also in some kind of superimposed form of wave and particle nature simultaneously and the act of measuring whatever it might be makes it collapse in one of the states but it also simultaneously loses its wave nature while collapsing.
Also, form Heisenberg's uncertainty principle (delta "wave nature" * delta "particle nature" >= h), once particle nature is completely deterministic, delta "wave nature" approach infinity and hence superimposed form cannot be regenerated.

These guys are so annoying asking physics questions in the theoretical computer science class ...

He says i don't know a lot..why js he teaching this stuff if he doesn't know it??
