5 Physics Equations Everyone Should Know
Our physics expert picks his top-five equations, plus a scheme to supply US power needs with a bucket of baseballs. Thanks, Einstein!
“A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Although we can use Newton's second law to understand the behavior of a baseball or the moon orbiting the Earth, this doesn't work when we get to super small things like electrons and protons. If you don't like water (you should), there's a whole range of technologies based on quantum mechanics: lasers, atomic clocks, LEDs, and of course semiconductors (used in the computer you’re reading this on).
