Cité Internationale Universitaire de Paris For the second year of my Master in high energy physics, I am studying at the École Polytechnique in Paris. This week I arrived in Paris and moved into my new room in the Cité Internationale Universitaire de Paris (CIUP). Established shortly after World War I, the CIUP today hosts […]

The Truel

How about another cool riddle? Three opponents, A, B and C, have agreed to a truel with pistols. You are A, and you are a poor shooter: you are only able to hit your target once out of every three tries. B is better, he can hit the target two out of every three tries. C never misses. In the interest of fairness, you […]

Deceptive Dice

Here an interesting riddle: The Terrible Twins, Innumeratus and Mathophila, were bored. “I know”, said Mathophila brightly. “Let’s play dice!”“Don’t like dice.”“Ah, but these are special dice”, said Mathophila, digging them out of an old chocolate box. One was red, one yellow and one blue. Innumeratus picked up the red dice. “There’s something funny about […]

In a Nutshell

To prepare for exams, I usually create summaries that cover the entire content of the lecture. I put a lot of thoughts into what to include and what to omit, so that the summaries are reasonably complete but still clearly laid out. That’s why I’ve decided to share them. If you’re interested in what is […]

Happy 2020!

I wish you all a Happy New Year! To start the year with a bang, check out my digital New Year’s card featuring a scientifically accurate electron explosion! Go to Card Screenshot Screenshot Screenshot The simulation (implemented in COMSOL Multiphysics 5.4) involves 2020 electrons that are placed randomly in a “2020”-shaped geometry. Since the electrons […]

Rearranging Nucleons

Nuclear Power Plants certainly are a timely topic. Once praised as the carbon-free energy source of the future, now mainly discredited for producing radioactive waste and posing a threat to entire regions, nuclear power plants have been occupying us for a long time. This post explains the physical basics of nuclear fission, where the energy comes from and what its hazards are.
