Dresden Science Night

A mathematical puzzle hike (6 to 99)
If you enjoy mathematical puzzles, come to the Willers-Bau!
Our puzzle trail starts at the pedestrian bridge over the Bergstraße in the direction of Willers-Bau.
With the correct solutions, you can guess a wise saying by a well-known mathematician and be named the "Mathematischen Rätsel-Ass der Langen Nacht 2024" (Mathematical Puzzle Ace of the Long Night 2024) at the information desk in front of room Willers-Bau C107!

Where is the dragon in the package insert? What is an Einstein tile? How do you build infinite bridges? (7-99)
A varied compilation of geometric shapes, interesting structures and colorful parquetry awaits you here: What pattern is actually in the folding of package inserts? Use secret codes to encode symmetrical parquetry and make your own tiles. With the Einstein tile you can puzzle non-symmetrical "patterns". Can you crack the high score?

3D digitization workshop
Personalized prostheses in medicine, prototyping in industry or digitization of collections: 3D scanning has many applications today. The team from the Geometric Modelling and Visualization working group at TU Dresden will show you how to scan objects "quickly" using a mobile 3D scanner. And then you can use the technology yourself to scan objects you have brought with you or to scan yourself.

Dr. Julia Goedecke

RSA: Residues, Security and Algorithms - Modular Arithmetics and Cryptography
In this workshop you will learn about cryptography and modulo arithmetic. Cryptography is needed everywhere in our modern world: for example, for secure internet communication, to protect government and industrial secrets or sensitive customer data, and to pay securely when shopping online. We constantly need the ability to transmit sensitive data securely and reliably. We will look at a few cryptographic methods (including RSA) and learn what this has to do with modulo computing.
In the workshop, you will be asked to join in and do the math. You will also get a little insight into the differences between school math and university math.

Hyperuniformity - From abstract mathematical concepts to more efficient solar cells
We explain how an abstract concept for classifying the arrangement of point clouds allows to identify a hidden order. Disordered hyperuniform systems, systems in which density fluctuations are suppressed on large length scales, are found in a wide variety of applications and often lead to unique properties. We highlight the current state of research to relate hyperuniformity to the resulting material properties.

Prof. Dr. Martin Keller-Ressel

Explainable AI - Understanding what the machine thinks
How can mathematics help to make the decisions of algorithms and intelligent systems comprehensible and easier to understand? Using examples from image recognition and automated vehicle testing, the lecture will present methods from the field of "Explainable AI".

Beer mat geometry
The lecture gives an insight into the world of hyperbolic geometry. The following questions will be discussed: How did M.C. Escher construct the amazing circular parquetizations? How does hyperbolic geometry differ from Euclidean geometry? What are Möbius transformations and how can they be visualized geometrically?
