Interacting with Physics
Drag an electric charge to see how it affects a nearby water molecule. Fool around with a laser to cool an atom. The University of Colorado’s Physics 2000 Web site relies heavily on interactive animations to demonstrate important concepts and discoveries in modern physics. Topics range from X rays and CAT scans to the quantum […]

Scrambled Grids
Amazingly simple mathematical operations can lead to intriguingly complex results. Consider, for instance, the iterative geometric process of creating flaky pastry dough. Flatten and stretch the dough, then fold it over on top of itself. Do it again and again and again. Repeating the pair of operations–stretch and fold–just 10 times produces 1,024 layers; 20 […]
