Boulder hall Energiehaven
I started bouldering around the time that I started my Masters program and absolutely fell in love with it. Energiehaven sets a very high standard for boulder gyms. The routes are changed frequently and are often very creative. The hall is large and there's even an outdoor wall.
I can't believe I only went here recently. This is such a nice place to visit if you want to see some animals, but don't feel like paying money or traveling to another city. It's also a great place to drop by if they ran out of chicken at your supermarket :)
David de Wied building
I used to come her daily during my Bachelor thesis. Up on the 4th floor I would tiny catalyst particles made of silver. The building has a very open feel due to its large glass windows, and internal balconies from which you can observe each individual floors.
Like most chemistry students, I joined Proton immediately at the start of the Bachelor. During my studies I have joined 4 different committees and helped organize many activities, both recreational and educational. I have also enjoyed many activities organized by other committees, like borrels, parties, and trips/camps.
