Mathematica is installed on many computers in the basement of the Science center.
It might also be installed on some computers in the houses. If you want to try
an installation of mathematica on your own computer,
get it here.
Note that you have to be on a Harvard network and have your PIN ready to download the
software and that requesting the Mathematica Password requires you to send the
request from a Harvard computer.

Installation

After you downloaded the program to your computer, start the application and follow
the instructions. During the installation progress, you have to enter the
Harvard Licence number L2482-2405. The number which you will get in return has
to be entered in the Mathematica Registration page. You will then be sent a
password by email. This is what you see during installation in

Mathematica is started like any other application on Macintoshs or PC's.
On Linux, just type "mathematica" to start the notebook version, or
"math" to start the terminal version.
