Random Analogies
"Diseased nerves are like "rusty wiring" that impairs the impulse or message to the skin, muscles, and organs that they ordinarily regulate."
"The alternative is to be didactic. Grab the player's attention, force him to listen to what you have to say. Have the characters talk at his doll. Make them emotional. Make him feel. Didactic art is like a man on a street corner holding up a sign saying Repent Your Sins. It's boring, like school, or a tedious sermon in church. Didactic lecturing doesn't tug on the heart strings in the way that its deliverer intends. And the more he does it, the more the player becomes antipathetic toward the art rather than sympathetic."
"Pi bonds are like pointing two fingers at the ceiling and moving them sideways until they touch. Unlike sigma bonds, pi bonds cannot rotate and maintain the bond; you can see this in our finger model, as turning your fingers out of alignment breaks the connection. Therefore, double or triple-bonded atoms cannot rotate relative to each other."
