Information Day

Teachers of mathematics, computer science and physics invite school pupils to an information day on 12 June 2026. From 9:30 a.m., upper secondary school pupils are welcome to visit the university's STEM campus between Albrechtstraße and Barbarastraße. Professors and staff from the faculty and the Central Student Advisory Service, as well as students and graduates, will give an insight into studying at Osnabrück University on this day. In various workshops, participants can carry out experiments in our laboratories, make their first programming attempts in our computer rooms or deal with theoretical questions and learn about completely new research results such as the "Spectre tile". At the "Market of Opportunities", graduates from our faculty will report on their work and give an insight into the career options available after graduation. Students will present their project work and look forward to chatting in the student council café. The central student advisory service will be on hand to answer questions.

The processor: A journey into the heart of the computer

Processors are the heart of every computer system, whether in a notebook, mobile phone or for controlling a car. They are used everywhere to perform highly complex tasks at breathtaking speed. But how do these little all-rounders work? In this workshop, we take a deep dive into the inner workings of a processor. We want to understand the basic functionality and design a small processor ourselves on the computer and bring it to life.

A look into the laboratories of ultrafast physics

Visit our physics laboratories and learn where and how phenomena on the ultrashort pulse time scale such as the self-localization of charge carriers in highly polarizable media are investigated. Methods include time-resolved techniques in UV/VIS and MIR spectroscopy, which can be used to record dynamic changes in both electronic structure and vibronic bands. The ultrafast control of light with light for information and communication technology (ICT) and the conversion of solar energy (photovoltaics and photothermal energy) play an important role in the application context.

The game Dobble - and the maths behind it

Dobble is a card game in which there are eight symbols on each card. The aim is to discover the common symbol on two face-up cards as quickly as possible. Without maths, it is not so easy to design an extensive deck of cards and symbols in which two cards match exactly one symbol each. The cards somehow behave like non-parallel straight lines, which also intersect at exactly one point. In this workshop we will play, tinker and learn about the projective plane over finite arithmetic domains.

The checker-jumping problem

In this mathematical game, pieces can move around an infinite chessboard by jumping over other pieces. Skipped pieces are removed and you can start with any number of pieces. In this workshop, we will not only play this game, but also answer various questions: How many game pieces does it take to reach a certain height? How high can you even get?

The physics lab in your cell phone

A smartphone is equipped with many sensors: gyroscope, microphone, acceleration sensor, magnetic field sensor, etc. The free phyphox app developed by RWTH Aachen University provides direct access to these sensors. This makes it easy to carry out exciting physical experiments yourself. In this workshop you will get to know the app and we will experiment together. Please bring a smartphone to the workshop.

Discover the campus with mathematical glasses

Mathematics is everywhere - in steps, paths, buildings and movements. With the MathCityMap app, we go on a mathematical search for clues on campus: What angle of inclination of the lower edge of the building determines the architectural effect of the lecture hall building, known on campus as the "frog"? How many different ways are there to take the stairs to the lecture hall?

In small teams, the participants solve mathematical problems on site. They then get creative themselves and design their own mathematical challenges for others.

You do not need your own mobile device.

Neural networks for beginners

Neural networks are one of the key technologies of artificial intelligence. In this workshop, you will explore how they work in practice and train your own small networks. You will learn about their capabilities and limitations and gain an insight into how this technology is used. The tools used will also enable you to use them in your own projects.
No programming skills are required!

How do Large Language Models work?

AIs such as ChatGPT, Gemini or Claude are on everyone's lips and a basic building block of many current technological developments. The underlying technology of these AIs is the so-called Large Language Model (LLM). In this workshop, we will explore how it works in practice by looking under the hood of a small example LLM. You will learn about the capabilities and limitations of LLMs, gain an insight into how this technology generates texts and learn how to better assess the results of LLMs.
