My name is Alan Rendall. I come from Scotland originally but I have been living in Germany for many years.When I started this blog I was working in Potsdam and living in Berlin. I later moved to take up a mathematics professorship at the University of Mainz. I am a mathematician by training and conviction. My professional web page is here. In this blog I write about topics which interest me without restriction as to subject. I am fascinated by biology and medicine, particularly immunology, and this has a big influence on the choice of topics.
Why do I maintain this blog? Here are some reasons.
1. I find that writing about a subject is an excellent way of learning and of fixing knowledge. I write in order to teach myself. The advantage of doing so in a blog is that it imposes a certain discipline. Knowing that someone might read what I am writing motivates me to be very careful about verifying the facts. This is all quite independent of whether anyone other than myself actually reads the posts.
2. I hope that from time to time someone who knows something about the subject of a post which I do not know or can correct something I have got wrong will provide a helpful comment. This does happen occasionally although unfortunately not very often.
3. The blog is a way of spreading knowledge about topics which I feel deserve to be better known.
4. I enjoy it. I can write about a much wider range of subjects and in a more relaxed and personal way than when I am writing research papers.
