Visit this scrapbook of the development of quantum theory. Describe
Einstein's perspective on the idea that one could never predict
the precise moment when an atom would emit a quantum of light.
Surf through the implications, examples of, and questions
about the photoelectric effect. What causes electrons to be
ejected from a metal surface?
Page of Uncertainty
This is a review of uncertainties in quantum mechanics, with
some good history on the subject. Why is the uncertainty principle
not observable with large objects, like baseballs?
Trips to Black Holes and Neutron Stars
Discover the astronomical implications of quantum mechanics.
How are black holes and neutron stars related to quantum mechanics?
This page explains how electron microscopes work. What is
the difference between SEMs and TEMs?
