Support my work

I make my high quality learning material available to everyone under a public copyright license, since I believe that only education can lead to advances in science and that only educated people can judge about the advances and risks of technology. Knowledge is the only way to craft differentiated opinions and decision.

I have spent several hundred hours of intense work to create these contents. Your support does help me to enrich the contents and to continue my work. There are many ways how you can support.


Patreon allows creators of public online content to fund their work through the crowds. Through you! By becoming a Patron of my work, you can not only ensure that I will be able to continue my work, but further I will be able to reward you for doing so. For example, you can be listed as an Official Supporter including a link to your homepage. Become a Patron
