The Scientific Method

Remember in science classes in school when you knew what the result of a calculation was meant to be (the acceleration due to gravity, the speed of light in a vacuum, etc.) so you just worked back from that and from the formulae to invent the "data" that your experiment "measured"? Maybe the more daring among us would eventually have given up on that charade and produced something like the paper entitled Electron Band Structure In Germanium, My Ass.
