HEY, MAN, ARE YOU USING ONLY HALF YOUR BRAIN? You're pretty hip. We all know that. You can throw an I CHING hexagram and intuit its meaning. You know all about Hedonic Engineering and staying high. You've seen through all the social games. When it comes to the neurosomatic circuit of the brain, and body wisdom, you're a champ. And everybody knows it. But what about those mysterious left-hemisphere brain functions? Would'nt you like to learn the secrets of the West, previously known only to the adepts at the esoteric Princeton Institute for Advanced Studies? Stranges arts like the Equation, which predicts things before they happen, or the Syllogism, which allows you to test an argument for internal validity? Or would'nt you like to know how the mysterious Stereo works, or what keeps planes from falling out of the sky? Imagine trying to live with one eye, or one lung, or one testicle. Is'nt it equally a handicap to use only half your brain? Subscribe to SCIENTIFIC AMERICAN (__) (oo) /-------\/ / : :: * ::----:: ^^ ^^
