You can get a great workout by walking up the stairs in a tall building. The only problem is that you can’t watch TV while doing it—hence the popularity of stationary stair-climbing machines. But is it the same? If your goal is to burn calories, does it make any difference which you choose? That’s actually a great physics question, and we can get a pretty good mental workout with it. Shall we? The Work-Energy Principle OK, what is a calorie, anyway? It’s a unit of energy, defined as the amount

The original version of this story appeared in Quanta Magazine. They say a bird in the hand is worth two in the bush, but for computer scientists, two birds in a hole are better still. That’s because those cohabiting birds are the protagonists of a deceptively simple mathematical theorem called the pigeonhole principle. It’s easy to sum up in one short sentence: If six pigeons nestle into five pigeonholes, at least two of them must share a hole. That’s it—that’s the whole thing. “The pigeonhol
