Any physics professor who thinks that lecturing to first-year students is the best way to teach them about electromagnetic waves can stop reading this item. For everybody else, however, listen up: A new study shows that students learn much better through an active, iterative process that involves working through their misconceptions with fellow students and getting immediate feedback from the instructor. The research, appearing online today in Science , was conducted by a team at the University of British Columbia (UBC), Vancouver, in Canada, led by physics Nobelist Carl Wieman. First at the University of Colorado, Boulder, and now at an eponymous science education initiative at UBC, Wieman has devoted the past decade to improving undergraduate science instruction, using methods that draw upon the latest research in cognitive science, neuroscience, and learning theory.

These photos have been around a long time but I have to thank my son for pointing them out to me. They were taken by the legendary Harold Edgerton in the Nevada desert at a range of 7 miles at 1/1,000,000,000th of a second, at night. These 3 pictures show the first 3 milliseconds of an atomic bomb detonation.
