Fighting the Current

Physics... ARGH!

I really hate studying for Physics. I have a two chapter test tomorrow. I understand the concepts as well as possible, but I can never keep the letters and numbers straight in the formulae!

Okay, my Physics teacher is a PhD chemist who used to work in the private sector. In the corporate world, not every formula has to be memorized. If scientists went around trusting their memories completely, they could end up screwing up something minor and losing their company lots of money. He should know this. So why should we be expected to know the formulae by heart? If we understand how to use them, and understand the concepts behind them, and know how to manipulate them, that should be more important than knowing off the top of our heads that g=(GMp)/(d^2). I think that's the right formula for gravity... I can't do sub- or superscript.

And it's eight o'clock. And I have no idea where to start studying for this test. And I may use the argument in the last paragraph to fight for the formulae to be written on the board....
