rallain | November 12, 2008Numerical calculations are grand. Of course, they are just another form of normal calculations - like I have said before. So, I have mostly used [VPython](http://vpython.org) for my calculations on my posts. But there is a new game in town: [Easy Java Simulations](http://www.um.es/fem/Ejs/).
