Gene Rodenberry on technoabble, from "The Making of Star Trek" (and courtesy of TBBS user jayrath, because google keeps taking me to his post):
Don't explain everything. Just do it. Roddenberry pointed out that cops on detective shows didn't explain how the firing pin struck the end of a shell, causing the bullet to leave the barrel. Similarly, you don't need the captain to draw a phaser and describe how it works before using it. Or the transporter. Or the engines. GR shared anexampleof a TOS script thatcontained many pages about how the ship was to changedirection.He deleted it all and inserted, "reverse course."
