The Shaken-Soda Syndrome

Try this! Take two identical cans of soda (or some other beverage). Roll then down a slight incline to confirm that they roll at about the same speed. What do you think will happen if you shake up one can and roll them again? Make a prediction. Then try it. Have your students do it. Develop hypotheses and test them. This is a terrific experiment that anyone can do.

Impact Event at the Permian-Triassic Boundary: Evidence from Extraterrestrial Noble Gases in Fullerenes

It has been twenty years since Luis Alvarez suggested that the dinosaurs were extinguished by a meteor impact that killed much of the life on earth. His evidence was in a thin layer of iridium-rich soil that corresponded with the extinction, and the fact that iridium is much more abundant in some meteors than it is on earth.

The Physics of Gridlock

How is automobile traffic like a gas? No, it's not because the collisions are inelastic. Researchers in chaos theory, especially Dirk Helbing and Boris Kerner, both theoretical physicists, have been working on traffic flow, using models similar to those of particle dynamics.
