Long Night of Astronomy - Impressions
About 300 astronomy enthusiasts came to the RUB on Saturday evening (19.10.24) to explore with us and our amateur astronomer colleagues from Ad Astra the wonders of the night sky:
- watch comet Comet C/2023 A3 (Tsuchinshan-ATLAS),
- investigate Saturn and the moon with optical telescopes,
- and make first observations with the radio telescope of the new Campus Observatory.
Open house with the mouse
On 3th October, the Faculty of Physics at the Ruhr University Bochum invited children to the Mouse Day. After the physics show, the children experimented in numerous workshops and explored the world of physics. Participants learned about plasmas and their important applications in the plasma workshop, such as coating surfaces. They were able to ignite plasmas, experiment and coat samples using the sputter coater.
Plasma School
The 27th International Plasma School on "Low Temperature Plasma Physics: Basics and Applications," took place from October 5 to October 10, 2024, in Bad Honnef, Germany. The Master Class titled “Plasmas, Liquids, and Nanomaterials,” was held from October 11th to October 12th, 2024. For more information , please visit our website: www.plasma-school.org.
Physical Review Letter on turbulence
Our scientist Rainer Grauer was involved in the development of a new approach to describe turbulence mathematically, together with his student Sumeja Bureković and long-term collaborator Tobias Schäfer (City University of New York).
In particular, irregular fluctuations, so-called intermittency, which cannot be described with a normal Gaussian distribution, are addressed.
They developed an approach using instantons - represent the probabilities of turbulence as a spatio-temporal path integral. This method allows for the first time to describe and calculate isolated and localized fluctuations, which is a major step in solving one of the big open questions in classical physics.
