Hands-on mathematics

The stand from the Institute of Mathematics offers a variety of opportunities to get to know mathematics: Test your logical thinking skills in the "Maths Quiz" with exciting puzzles and brainteasers. Various exhibits offer "hands-on mathematics" in the form of challenging mathematical games.

 

With vehicle communication into the future

Vehicle communication is considered a key technology for tomorrow's mobility. The exchange of information between cars among themselves and with the environment can increase road safety and enable economical driving. The Institute for Distributed Embedded Systems is researching techniques to make this communication reliable and safe.

 

Measurement of water quality

With simple electronic circuits self-constructed on a pin board some properties of water shall be determined experimentally. Does the addition of foreign substances such as salt, sugar or clay change the electrical conductivity and turbidity of water? Both quantities are to be measured simultaneously. How do these values differ for water of a different origin (tap water, paderwater)? How can the measuring circuits and equipment be improved?

 

Double Pendulum

The double pendulum is a model for a chaotic system. By means of long-term recordings with a camera we reproduce the oscillation course of a double pendulum and print it on a postcard. In simple terms, a chaotic system is a deterministic process (i.e. it does not depend on chance), whose course depends strongly on the initial conditions: small changes in the initial conditions lead to large changes in the course. In practice, this makes a chaotic system almost unpredictable, since the initial conditions (and possibly small disturbances) cannot be measured accurately enough. So it is very unlikely that you will get similar trajectories when the double pendulum is swinging (at least if the starting angle is sufficiently large), and in this sense our postcards are unique.

 

Optical polarization in glass fibres: representation, modification and control

Vibrations can greatly change the polarization of light in optical fibres within a short time. We show how this affects the polarization and how it can be stabilized again.

 

Creating tension as engineer and teacher

Practical examples from the (teachers) study of Electrical Engineering invite you to participate. How can you generate voltage? Make an effort and make the lamps light up. But why is it more strenuous to make an incandescent lamp glow than an LED lamp? You try it out and learn something. Learning must also be exciting! All exhibits were developed by students studying Electrical Engineering. They study this subject but not only with the aim of becoming an engineer*in a day. Their aim is to teach students in Electrical Engineering at a vocational college - and to do so as excitingly as possible.
