Mathematica is an extremely powerful math tool. The Eindhoven University of Technology has a site license, but only for the Windows platform. The serial number and registration provided, will not work on a Mac OS X computer. But Wolfram has got you covered! You can apply for a Home-use license, even one for Mac OS X. You need to fill in the online form and after a manual validation, they approve your application. I tried it out and I am now the proud owner of a Mathematica liscence for Mac OS X at the TU/e. Voila!
