My Diploma thesis turned 20 years old on the 6th of March 2026. In 2006 the Bologna reform was still not implemented at University of Bremen and hence I received a diploma in Chemistry which would be called a Master of Science these days.  I thought this anniversary would be a fun occasion to present my thesis to my current colleagues at Chalmers University and so I did just that. There were even more people interested than I first anticipated and I even received a card and flowers. This can be a really nice opportunity to show to students how a thesis looked twenty years ago and that also the now supervisors or seniors did by far not do everything "correct" from the start (which would imply that this happens now...well). I also was amazed how the topic and technology behind what I was writing about had developed in the last two decades. I write a bit about the project in this entry here. Looking back, I think that I learned really a lot during that time, even tough the results may not have been groundbreaking or amazing. But it certainly helped on the way of becoming a scientist and I thank my supervisors for that.
