What invisible power is in magnets? - Dr.-Ing. Tom Ströhla

Electric drives move our world everywhere - electric cars, e-bikes or robots. But you can also find electrically powered devices in the household or in the children's room - can you think of anything? Almost all of these devices use electromagnetic forces. Dr. Ströhla and his colleagues from the Mechatronics Department explain the different magnetic forces there are, how these invisible forces are created and how you can use them to build very different drives.

"Why is the world so colorful?" - Prof. Dr. Peter Scharff

What do you think of when you think of colors? In nature and in life we ​​encounter colors at every step. They play an extremely important role in our lives; they are, so to speak, the result of the interaction of the most varied of chemical structures with light. Why are dyes actually colored? Why is the blood red and the leaves green? Can you see colors in the dark? How are colors actually made? We want to give you an answer to all these questions and other questions in this lecture and show you in great experiments how chemistry makes the world more colorful.

"How do you make light effects dance to the rhythm of the music?" - Prof. Dr.-Ing. Ralf Sommer und Carsten Gatermann

How can you program a small computer to create different lighting effects for music? We will show you many examples of what is hidden behind tones, sounds and music, how you can change them and how you can build a small computer for them. Together we develop a program that turns various sound properties into a play of lights.

"The fascination of interference" - Prof. Dr.-Ing. Eberhard Manske 

Interference, that is, the superposition of light, is a wonderful natural phenomenon: light plus light results in darkness. The fascinating colors of a soap bubble or the shimmering colors of a beetle are based on this effect. Since the ingenious invention of the Michelson interferometer, interferometry has made a real triumphant advance in science and technology. Today, their use ranges from high-precision machines, e.g. for the production of integrated switching devices, to exploring space and the secrets of gravitational waves. With the lecture we give an insight into the fascinating world of interference phenomena, the nano world and precision.

COVID, lockdown and conspiracies: Does talking power (un) healthy? - Dr. Andreas Schwarz

Wear a mask, keep your distance, stay at home ... In the time of the corona pandemic there was and is a lot of information on how to behave. This is how you should protect yourself and others from illness. But other voices were also heard speaking of gloomy conspiracies by the government and those in power. In the lecture you will get insights into how communication works during health crises, how fakenews or conspiracy myths spread and what effects this has on the health of all of us.

"What is a fair wage for work?" - Prof. Dr. Michael Grüning

Even if adults don't like to talk about their own income, people earn different amounts. Why is that? There are many perspectives from which one can answer the question of a "fair" wage. From the point of view of economics, we want to shed light on why the management board of a large company receives a multiple of the cleaning staff's remuneration in the same company, whether they really "deserve" it and how the "earned income" for certain activities can be determined.

"Medical technology under tension"- Dr.-Ing. Eva-Maria Dölker

Biomedical technology is technology for life - it has a direct effect on human well-being. Its aim is the research and development of technology-oriented methods and systems for the early detection, diagnosis, therapy and rehabilitation of diseases. Be there live at an interactive lecture from the Institute for Biomedical Engineering and Computer Science. Find out what the measurement of electrical voltage has to do with muscle strength, physical fitness and brain activity and get to know the research focus of "electrical warning", where electrical current surges are explored as a way of warning people!

Math for the gods - Prof. Dr. Thomas Hotz

North India, 800 BC Martial tribes from Central Asia conquer the country. In order to secure the support of their gods, they construct altars - again and again, wherever they have set up camp. But the altars must have precise geometric shapes, such as exact squares; otherwise the victim can fail - with catastrophic consequences! But how do you construct a square in the field? The lecture shows how this succeeded - and what mathematical knowledge the Indians already had at that time.
