So i was thinking that thought is not seperable from sensory experience. In order to think, you must have something to think about. Now that's all dandy until i thought of math and science. We don't see numbers, we don't see exponential functions, etc... We come up with that, induction and deduction. So where do YOU think it comes from? Are we programmed with a sense of math and science? Or... what other reasons can you think of?

hi every1
i have a little question here, when a pice of paper is put on a half full glass of water and the glass is flipped, the paper doesn't fall, why??
well i know if the glass if full, the paper doesn't fall because the pressure of water acting on the paper is less than that of air, but when it's half full three pressures act on the paper, two from inside the glass (air and water), and air from outside the glass, which -i think- makes the pressure of air and water inside the glass more than the pressure of air outside the glass..

can u give me a detailed explination plz..
thanks..

you have to use the difference formula for tangent, (60 -45), but I keep getting a different answer from the back of the book, the book's answer is 2 minus the square root of 3
