Default Re: Wandsor's equations

You need quite a few equations to predict how to hit a tennis ball, yet a lot of people manage it without thinking. So I don't think calculus is essential for predicting something - it's just essential for making the prediction numerically accurate. (An interesting experiment would be to judge how far to fill a cylindrical glass of water so it can exactly fill a spherical vase - can your brain do the rough calculation by gut feeling?)

Edith, is your exam on calculus or on glass? Either way good luck!
