Activities
- How to form a state as a column vector in matrix representation.
- How to do probability calculations on all three representations used for quantum systems in PH426.
- How to find probabilities for and the resultant state after measuring degenerate eigenvalues.
Students each recall a representation of vectors that they have seen before and record it on an individual whiteboard. The instructor uses these responses to generate a whole class discussion that compares and contrasts the features of the representations. If appropriate for the class, the instructor introduces bra/ket notation as a new, but valuable representation.
