Description and Timestamps:
The main idea of this section connects measurement in Quantum Mechanics to linear operators - matrices - which act on quantum state vectors. This is the first of many passes through this material, and we start the discussion using our knowledge of spin and the two-level systems from section 1.
In this module we will review:
1. Observables in Quantum Mechanics
2. How observables act as Linear Operators
3. Expectation Values for Operators
4. Statistical Variance
Timestamps
2:06 : Measurement of Spin and the Spin operator
4:54 : Measurement Rant.
6:32 : Definition of the Expectation Value and 3 examples
11:08 : Statistical Variance
13:12 : A few examples
