Revisited Stern-Gerlach setup, now using three machines in series.

Introduced incompatible operators.

Reintroduced normalized and phased notation, using δ. (pic)

Combined y and x to view result of <+y|+x>


Talked about projections on other axes (pic x2)

Practice problem (pic) performed partially in class

	what is the probability that the S_y will be measured to be +ħ∕2
		Should be .93
		To find, calculate <+y|Ψ> to find probability.

	What is <S_y>? I.e. the expecation value for S_y?
		<Ψ|S_y|Ψ> gives expectation value, or use <+y|Ψ> and <-y|Ψ> to find coefficients. (pic)
