Brian Greene's Introduction.
The double-slit experiment
Waves of probability.
Participant Introductions.
The classic outlook changed forever.
The Norman Ramsey approach to quantum mechanics.
The quantum measurement problem.
Does there need to be a clear separation between the quantum description and the observer?
How does the double slit fit into this example?
The many worlds approach to quantum mechanics.
If we can't see the other worlds, isn't that equal to believing in god or angels?

Spontaneous collapse theory.
How do you make this theory precise.
Tallying the votes for collapse theory.
What is Qbism?
