This site seems to be very interesting mainly because the site describes some mathematical problems people encounter when trying to solve a particular problem. Then they give a sample program that you can actually run in DOS, and see how that particular problem is solved. It featured 22 countries exchanging ideas from different parts of the world concerning numerical analysis and scientific computing. This site is wonderful. Everything is open for public view.
Topics range from the beginnings of calculus to Fermat's last theorem.
It is a very comprehensive listing of the history behind mathematics. This is an interesting site because it includes a lot of topics that relate to Numerical Analysis. This site has everything you ever wanted to know about numbers but were too afraid to ask. This aforementioned site is quite interesting. We as college students use this value of PI as 3.141 that's it nothing else.
