Mathematics in space: Gauß lecture inspires Bochum!
On October 29, 2025, Prof. Dr. Helmut Hofer and James Green in Bochum on mathematics and spatial research. Registration recommended.
Mathematics in space: Gauß lecture inspires Bochum!
The “Gauss in Bochum” event will take place on October 29, 2025 and will focus on the young and exciting relationship between mathematics and space research. The Faculty of Mathematics at the Ruhr University Bochum is organizing this public lecture, which will take place from 4 p.m. to 7 p.m. in the O-Werk at Suttner-Nobel-Allee 4 in Bochum. The renowned mathematician Prof. Dr. Helmut Hofer from Princeton University will shed light on the chaotic and often overwhelming work of mathematicians. He describes this work as “chaotic, exciting and often overwhelming,” providing a deep insight into the challenges and fascinations of the field.
In addition, former NASA boss James Green will speak about the search for life in space, explaining the essential role of mathematics in this context. Both speakers will be available to answer questions from the audience at the end of the event, which underlines the interactive nature of the event. The lectures will be held in English.
Mathematics as the basis of space research
Mathematics plays a fundamental role in space exploration. It guides spacecraft, determines exoplanet sizes and predicts orbits of near-Earth asteroids. It also uses gravitational chaos to save fuel. Celestial mechanics serves as a testing ground for mathematical ideas that are not only theoretically but also practically important. These facets of mathematics form the basis for modern astronomy and illustrate how closely this discipline is linked to discoveries in space.
The event not only offers a platform for expert lectures, but also a musical conclusion with the jazz quartet under the direction of Ivan Habernal. Those interested are invited to register using an online form.
The historical context of mathematics in astronomy
In order to better understand the importance of mathematics in space research, it is essential to take a look at the history of Johannes Kepler. In the 17th century, Kepler revolutionized the understanding of the universe through his observations and mathematical calculations. He realized that mathematics was the key to unlocking the cosmic order. His three laws of planetary motion - the first law about the elliptical orbits of the planets, the second about the varying speed of a planet depending on its distance from the sun, and the third about the relationship between orbital period and distance - revolutionized astronomy and laid the foundation for classical mechanics, later developed by Isaac Newton.
Kepler's approach to viewing mathematics as both a tool and a vision remains central to this day. He believed that understanding universal laws was possible through mathematical relationships. His combined use of mathematical analysis and empirical observations is considered groundbreaking and underlines the timeless relevance of mathematics in science.
The Kaven Prize of the German Research Foundation (DFG) will also be awarded as part of the event, the winner of which will be announced a week in advance. In 2025, Bochum will be the venue for the Gauß Lectures for the first time, which have been taking place annually at different locations in Germany since 2017.
Prof. Dr. is available for scientific information. Christian Lehn from the Faculty of Mathematics at the Ruhr University Bochum is available. Anyone interested can contact him on +49 234 3223247 or by email at christian.lehn@ruhr-uni-bochum.de.
