2. Learning Goals for Chapter 2 – Heisenberg’s Uncertainty Principle
After this chapter, the related homework problems, and reading the relevant parts of the textbook, you should be able to:
construct a simple wave packet from plane waves and explain the result verbally and graphically
formulate HUP mathematically for several pairs of variables
explain the consequences of HUP using examples
use HUP to estimate orders of magnitude of uncertainties of position, momentum, energy, etc.
