omega tau science & engineering podcast

This episode is a conversation with Volker Springel about the Millenium Simulation, which at the time was the largest simulation of the growth of cosmic structure, including a detailed model for the formation of galaxies and supermassive black holes. In the episode we talk about the physical/cosmological background, the simulation process and approach as well as some details about the hard- and software.

This episode is a conversation with CERN's Rolf Landua about the Large Hadron Collider. We start out by discussing the science and theory behind the LHC what the LHC aims to research, including the higgs boson, the standard model, super symmetry and extra dimensions. We then talked about how the LHC works (proton source, acceleration, superconducting magnets). We conclude the conversation by looking at the LHC experiments and discussing in some detail how the ATLAS detector works.

In dieser Episode unterhalte ich mich mich mit Prof. Dr. Manfred Bischoff vom Institut für Baustatik und Baudynamik der Uni Stuttgart. Wir unterhalten uns über die Auslegung von Gebäuden und Brücken sowie über mathematische Verfahren zur Berechnung und Simulation, insbesondere die Finite Elemente Methode.

This episode covers neutron science at the Institut Laue Langevin in Grenoble. Helmut Schober and Ulli Köster cover what neutron science is used for, some interesting scientific experiments conducted at ILL as well as the physical fundamentals and the workings of the reactor and the detectors. We conclude the epsiode with a discussion of the ILL as a "research service facility" that offers all-around research support to visiting scientists.

Gespräch mit Professor Heiner Igel über Erdbeben und Seismologie. Es geht darum, wie ein Erdbeben entsteht, welche Art von Wellen sich ausbreiten, wie man diese messen und die Stärke des Erdbebens bestimmen kann. Außerdem sprechen wir darüber, welche weiteren Informationen man aus den Messdaten gewinnen kann und an welchen Themen aktuell geforscht wird.

This is an episode on how satellites work with James Penson from Surrey Satellite Technology. Specifically we talk about satellite buses, the infrastructure part of the satellite on which the (typically scientific) payload is mounted. The conversation covers structure, thermal protection, energy supply, communication, guidance and attitude control as well as propulsion. This will be the last episode on space related topics for the time being :-)

This episode is a bit different. I produced it together with Joe D'Eon from the wonderful Fly With Me podcast. Together, we explored the question of how aerodynamic lift really works - in other words: why airplanes fly. He went out and asked a fellow pilot about what he thinks how lift works. I went to the University of Stuttgart's Intitute for Aero- and Gasdynamics and talked with Thorsten Lutz. He explained the details of how it works. If his explanation still doesn't do it for you, take a look at Wikipedia. They have a couple of nice illustrations.

Diese Episode ist ein Gepräch mit Michel Hügler über Meeresbiologie und Tiefseeforschung. Michael beschäftigt sich mit der Mikrobiologie von Kleinstlebewesen an Hydrothermalquellen und war mehrmals mit Forschungsschiffen und U-Booten an diesen "Black Smokers". In dieser Episode reden wir über die biologischen Aspekte, über Forschungsreisen und über die U-Bootfahrten.

This is the third and final episode covering the interviews I did when I was visiting NASA Ames. It consits of two interviews. The first one is about Ames' involvement in the Ares/Orion projects which are part of the Constellation moon/mars exploration programme. I talk about this with Dr. George Sarver. The second part of the episode covers small satellites and why they are becoming more and more important (compared to traditional, larger satellites). In this part, my guest is Elwood Agasid.

This episode covers my visit to the Max Plack Institut for Plasmaphysik where I spent a couple of hours with Matthias Reich talking about nuclear fusion. The episode has three parts. In part one we talk about the scienfic and physical basics of nuclear fusion. Part two covers some of the ways the MPI facilities work, and part three discusses the ASDEX Upgrade experiment at IPP in Garching.
