The physics of everyday life OCT 26 2010
Christoph Niemann hits another one out of the park with an illustrated look at the how physics governs everything we do in life.
I loved his idea for calorie-neutral foods:
All you need is to freeze a pint of ice cream to -3706 F. The energy it will take your system to bring the ice cream up to a digestible temperature is roughly 1,000 calories, neatly burning away all those carbohydrates from the fat and sugar. The only snag is the Third Law of Thermodynamics, which says it's impossible to go below -459 F. Bummer.
