The site is for everyone: students, teachers, university wannabe nerds and the general public. It is packed full of articles for every age group, and every level of science learning.

We also have a website dedicated to environmental issues: Umwelt.Science, which is in English and German.

If you have any problems using the tools, or have suggestions, or would like to contribute something, we would love to hear from you.

Enjoy your visit to!
