>Part of the part am I, which once was all, the Gloom

>That brought forth Light itself from out her mighty womb,

>The upstart proud, that now with mother Night

>Disputes her ancient rank and space and right,

>Yet never shall prevail, since, do whate'er he will,

>He cleaves, a slave, to bodies still;

>From bodies flows, makes bodies fair to sight;

>A body in his course can check him,

>His doom, I therefore hope, will soon o'ertake him,

>With bodies merged in nothingness and night.

It was not before 1960 that the first laser was built. Nowadays, it is hard to imagine a life without them. Form CD players, to tattoo removal, and up to high-precision medical instruments, they advance modern technology. This year's nobel price in physics has been awarded for the invention of ultrashort pulse lasers with extremely high energy, that play a major role in research, medicine and industry. We will teach you the basics of quantum optics that you will need to understand laser technology. Furthermore, we will show you how to use lasers for transport of information.

Research of relativity also makes use of lasers. In 2016, LIGO anounced that they were able to detect gravitational waves for the first time, using multiple laser interferometers. We would like to give you an idea of how how these detectors work and why they are so important.

Theory of relativity is also the gate to nuclear physics and the most controversial source of usable energy. We would like to discuss with you why research on nuclear fission is promising nonetheless. We will compare fossil fuels, solar power, wind turbines, hydroelectric power stations, geothermal heating and nuclear reactors with respect to their safety, efficiency and most of all their threat towards the environment. Maybe we will have one or two surprises for you. To experience radioactivity live and in colour, we will bring our home-made cloud chamber.

If you want to go deeper, maybe we can get you interested in quantum mechanics. It does not have to be a difficult and complex topic. We prepare some explanations that are easy to digest and we will answer all of your questions to give you an intuition for the basic principles of the universe, even without having to study physics for many years. Did you know that you could build a real random number generator just from some high-precision quantum detectors? If you would like to know how this works and why such a random number generator is much better than any built into a modern computer, please come to our talk on the topic. For real nerds, we will have some insights into quantum computing and the Einstein-Podolsky-Rosen paradox that was supposed to make nonsense of quantum physics.

We will also prepare talks about chaos theory and music theory with Hilbert space theory. You don't want to miss another talk, where we will show you Rostock's Schauvorlesung and whatever we do when we are not standing in a lab or sitting behind a desk.

For a fun time, we won't just make you pickle glow, but also show you how scanning microscopes work. Fluid nitrogen will make objects hover and change light's colour.

If you want to know what else we can show you, just come visit us and feel free to ask questions! We are always there for a nice discussion.

Thanks to the university of Rostock for making this possible!
