Leiden

While interviewing for PhD positions in Leiden, I found some quite interesting things. In between lab tours and presentations, I broke off from all the madness to see the campus for myself. I found a group of local students and asked them whether there is anything to see. I got a few shrugs, someone pointed to the canteen and the consensus was that this is just a boring brutalist campus. Mere steps away, I found this wall of signatures:

In the museum of scientific instruments, you can see e.g., Hugens's telescope of Leeuwenhoek's microscopes, Snellius' sextant:

And of course some graves. I really wanted to see Willebrord Snellius' grave: sadly, an even was being planned in Pieterskirk, and the site was blocked. However, a kind lady helped me get as close as possible, stating: "they cannot fire me, I am a volunteer". An unexpected find was Ludolph van Ceulen -- known for the Ludolphine number.
