Do they draw the power out quicker? I'm working on something but that thought crossed my mind and hindered my progress on my possible invention/contraption.

How do you find amplitude if you have the height measured. We are doing a spring lab and we are trying to find the Spring constant using Hooke's Law. We hung a spring and put a mass on it and measured how far the bottom of the mass hanger was from the table. The height was .511 m and the mass was .21 kg.

I am attempting to solve two coupled equations in two variables, say x and y. The problem is that one of the equations contains a term in dy/dx. There is no 'independent' variable per se. Both equations are quite nonlinear are require numerical solution. The NSolve and FindRoot functions will not work because of the differential while the Dsolve or NDsolve will not seem to work because of the lack of an 'independent variable to input. Any suggestions on how to approach this problem?

Me and a colleague were discussing, I seemed to remember there was some theory that humans lived semi-aquatically for a while we left the oceans way back in our evolutionary history, my colleague hadn't heard anything about that - any theories?!
