Presentation: "Physics Is Beautiful"

After being inspired by three videos on the topic of "Mathematics Is Beautiful", I would like you to present something that you consider beautiful in physics.

The inspiring videos can be see here:

In class we watched the 3rd one (with James Tanton) and the 4th one (with Ken Ono). I can also recommend the 2nd one (with Manjul Bhargava) but I have not watched the others.

We will only have time for a few presentations each week, nevertheless you should always be prepared to present.
