The license for Mathematica has been expanded temporarily to an unlimited campus license for the whole of 2023: all employees and students may use Mathematica unlimitedly in 2023 on the RU network. For home use, one must therefore use a VPN.
The software can be found on the C&CZ Install disc. During the installation you must specify:
License server: mathematica.science.ru.nl License: L4601-6478
The introductory course “Mathematica Basic Principles: An Introduction” can be taken for free at CANdiensten in Amsterdam.
