Mathematical ModelsMada an "introductory" page on Mathematical Models "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20091027 21:21:39
Re: Mathematical ModelsI really like this page. I think the example is a very good one, because it demonstrates that when improving a model, there's a point where the next thing that needs considering would make the calculations much more complex and the accuracy is already good enough that it's probably not worth doing. Why did the vector cross the road? It wanted to be normal. #3 20091028 01:33:07
Re: Mathematical ModelsHi MathsisFun; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20091028 04:20:12
Re: Mathematical ModelsThe page looks great. I just have one question. How did you figure out the minimum (0.22, 0.17)? #5 20091028 04:22:17

Re: Mathematical ModelsIt's also possible to use calculus to get the exact answer  the xvalue turns out to be Why did the vector cross the road? It wanted to be normal. #8 20091028 07:10:43
