• QUESTIONS BEFORE LECTURE 34

now think about these

• Give an ordinary wave example of the uncertainty principle for complementary variables.
• How does uncertainty in momentum affect uncertainty in position as time passes?
• How does the uncertainty between energy and time explain tunneling?
• How does the statistical or probabilistic interpretation of Psi-squared explain tunneling?
• What is Bohr's Principle of Complementarity and what does it tell us about measurement, or vice versa?
• Why do you think people have a hard time accepting wave/particle duality? Does it bother you?
• Why do you think people have a hard time accepting the uncertainty principle? Does it bother you?
• How does scattering (of particles) enter the theory of measurement, and how does that lead to the (wave) concept of uncertainty?
• What is information?
• Do we determine the nature of what we observe? Are we what we observe?
• When is it OK to use Newton's deterministic physics laws? Your answer should be in terms of h.
