Wissen um 11 - Dr. Betti Hartmann

On July 6, Betti Hartmann, university lecturer in Physics at Jacobs University, will take part in the ‘Wissen um 11’ series at Bremen’s Haus der Wissenschaft.

Her lecture titled “From flatland to hyper-spaceland – how many dimensions does our world have?” will be dealing with multidimensional theories in physics.

Abstract: 
We usually need four numbers to describe an event correctly: e.g. we could use the height above sea level, the longitude and latitude as well as another number to tell us when the event takes place. Hence we usually refer to our world as “four-dimensional”. In modern physics, however, there are theories that need more than these four dimensions. One example is string theory which presumes the existence of six more dimensions. If these really existed they’d have fascinating consequences such as e.g. the production of black holes in particle accelerators. With tests currently undertaken at the Large Hadron Collider (LHC) at CERN in Geneva scientists hope to gain further insight into such theories. The lecture will be held in German. It is part of the ‘Wissen um 11’ lecture series, taking place at Haus der Wissenschaft on Saturday mornings.
