Computer Pool — PRP
You can find two computer pools (PRP -- Physikalischer Rechnerpool) in the Physics Department. They allow you to browse the internet, work with software like Mathematica, write and print documents in Openoffice or LaTeX and many other things. You can even access the PRP from outside the university via the SSH protocol!
The pols are located in S2|01 and S2|04 on the ground floor.
In order to use the system you need to have an account. Fill in the application form, pay the annual fee of 5 Euro in the Physics Library (see above) and put the form in the mail box in PRP 1.
Considering the ridiculously low fee for using a good computer system, you should definitely get an account!
