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 the Willers Building B wing.
With the correct solutions, you can guess a wise saying by a well-known mathematician and be named the "Mathematical Puzzle Ace of the Long Night 2025" at the information desk in front of room B122!

Mathematical games and puzzles to solve yourself for everyone between 6 and 99
Many different games with tasks ranging from easy to difficult invite young and old to puzzle alone or with the whole family. There are more exciting puzzles on the boards in the rooms. We are already looking forward to a lively discussion!
Location: Willers-Bau C102-C106

Workshop 3D digitization
The "Mathematical Models" collection at the Institute of Geometry at TU Dresden comprises over 500 registered objects made of wood, plaster, cardboard, wire, metal and silk, mainly on descriptive and analytical geometry and function theory. In the collection laboratory, the historical teaching models are scientifically catalogued and made available on an interdisciplinary basis by means of 3D digitization and modelling. Visitors can try out the technology used for 3D digitization in small workshops

Prof. Daniel Lordick

Presentation of the "Mathematical Models" collection
The "Mathematical Models" collection is one of a total of 40 university collections and comprises around 500 registered objects from the mid-19th century to the present day. The materials used include wood, plaster, cardboard, wire, metal, silk and, most recently, 3D prints. The themes range from descriptive and analytical geometry to functional theory and three-dimensional fractals. The collection is supervised by Prof. Lordick. Part of the collection can be researched online. The website is part of the Digital Archive of Mathematical Models(DAMM) project. In the course of this project, 3D digital copies of part of the collection were created.

How do you find a zero?
Finding the zero of a given function is a task that is extremely important for many practical applications of mathematics. However, it usually does not work the way it is explained in school. We'll show you how it's really done.

Describing cell shapes mathematically - how does it work and why does anyone care?
Many individual cells form a tissue. But how are the properties of an individual cell, for example its shape, related to the behavior of the tissue as a whole? To answer this question, we must first describe the cell shape mathematically. In this lecture, we will look at how this works, what can go wrong and what we can learn from experimental data.

The future of learning: AI as a study companion in STEM
Artificial intelligence is changing the way we learn and work. In this lecture, I will show in a practical way how generative AI tools can support STEM studies, the advantages they offer and the challenges that need to be overcome.

From the seven bridges of Königsberg to pattern recognition.
In 1736, Leonhard Euler posed a simple question known as the problem of the seven bridges of Königsberg. This puzzle asks whether it is possible to walk the town of Königsberg in such a way that we cross each of the seven bridges exactly once. This problem is considered to be the origin of a branch of mathematics called graph theory with a wide range of real-life applications. In this talk, we will explore the origins of graph theory, and discuss some of its most popular applications such as vehicle routing, and pattern recognition.

This talk will be held in English!

Encryption - how arithmetic helps to communicate securely on the Internet
Modern internet communication would be unthinkable without encryption - and yet much of this security is based on seemingly purely theoretical mathematical considerations. In this lecture, we will introduce you to the fascinating world of the RSA algorithm, one of the best-known and most widely used methods for asymmetric encryption. We will impressively demonstrate how fundamental concepts of number theory - such as prime numbers, modular arithmetic and the Euclidean algorithm - work in a practical context.
We shed light on the mathematical foundations, explain how RSA works step by step and also discuss the limits and challenges in the age of increasing computing power and the development of the first quantum computers. The lecture is aimed at anyone who wants to learn how abstract mathematics becomes the basis for trust and security in the digital space - and why mathematics can do more than just provide formulas on paper.
