In the world of subatomic particles, where mere observation of a system actually changes the system, intuitive logic—what seems to make sense—does not apply. This program provides an entertaining overview of physics at the microcosmic level: quantum mechanics. Demonstrations, experiments, and video graphics, along with commentary by Leon Lederman of the Fermi National Accelerator Laboratory, elucidate such topics as Einstein’s theories of general and special relativity, the photoelectric effect, particle/wave duality, and Heisenberg’s Uncertainty Principle. The program brings the quantum physics discussion up to date by looking at David Bohm’s Seamless Whole Theory and the implications of Bell’s Theorem. A Discovery Channel Production. (48 minutes)
