Als Auftakt zu einer (hoffentlich ausführlichen :-)) Serie von Episoden zur Energieerzeugung und -versorgung geht es heute um Stromnetze im Allgemeinen. Unser Gast ist Veit Hagenmeyer, Professor am KIT und ehemaliger Kraftwerksleiter. Wir sprechen über Spannungslevel im Netz, Regelung mittels der Netzfrequenz, die Regelbarkeit verschiedener Kraftwerkstypen sowie die Herausforderungen die sich für das Netz aus der zunehmenden Verbreitung regenerativer Energiequellen ergeben.

During my visit to DLR's Earth Observation Center earlier this year I also talked to Dana Floricioiu about her work in glaciology. We discuss a couple of her recent publications, and then focus on her trip to the Darwin Glacier in Antarctica. Together with a team of fellow scientists, she camped on the glacier for three weeks to conduct various in-situ experiments. We discussed the work, but also life on the glacier.

Ich war am Earth Observation Center des DLR in Oberpfaffenhofen zu Besuch und habe dort zwei Gespräche geführt. Zunächst ging es mit mit Michael Eineder vom Institut für Methodik der Fernerkundung um Radarsatelliten und deren Einsatz für die Erdbeobachtung. Wir sprechen über das Funktionsprinzip von satellitengestützten SAR-Radar und betrachten außerdem die beiden Missionen TerraSAR-X und TanDEM-X. Im zweiten Teil spreche ich mit Stephan Kiemle vom Deutsches Fernerkundungsdatenzentrum über Satellitendatenarchivierung.

The increasing complexity of software requires increasingly sophisticated means of ensuring its correctness -- "just" testing is not necessarily good enough, depending on the domain in which the software is used. Formal specification, verification and proof is a field with a long tradition in computer science that is gaining more (practical) relevance these days; and in this episode, we cover the basics. Our guest is Benjamin Pierce, professor of computer science at UPenn. We discuss the nature of (good) specifications, how verification and proof is different from testing, and where and how these techniques are successfully used today.

This is the last episode recorded during my visit to ESA's ESTEC last fall. I get a tour of the Test Centre with the head of the section, Mark Wagner. We discuss the various test stands and facilities, including the thermal vacuum facility, the large space simulator, the thermal vacuum chamber, the vibration facilities, electromagnetic testing and acoustic testing.

During my visit to ESA's ESTEC last fall, I talked to Jose Gonzalez del Amo, who is the head of the Electric Propulsion Lab. We discussed the basics of electric propulsion, the pros and cons compared to chemical engines, different engine styles and their use cases, as well as the work ESA performs in the lab.

Im Dezember habe ich das Institut für Physik der Atmosphäre des DLR in Oberpfaffenhofen besucht. Dort habe ich mit dem Physiker Helmut Ziereis und Katrin Witte vom Flugbetrieb unterhalten. Neben Forschungsfragen und -vorgehen der flugzeuggestützten Atmosphärenphysik haben wir uns insbesondere über das Forschungsflugzeug HALO unterhalten.

David Woods has a new book out, so of course he has to talk about it on omega tau :-) His recent book is about the Saturn V launch vehicle, i.e., this time it is about the rocket, not about the spaceship. In this episode we dive into lots of details that we did not cover in the two Apollo episodes (episodes 83 and 97) -- make sure you have listened to those before you listen to this one.

In October 2015, Joseph Tainter was my guest in omega tau 184 to discuss his concept of increasing complexity and eventual collapse of societies. In this episode, our guest Paul Arbair discusses these concepts in the light of today's rising populism in several countries. The episode is based on two articles Paul wrote on his blog: one on Brexit and one on Trump.

Late 2016, during a trip to the Netherlands, I visted Rutger Vlek of River Creative Technology in his home studio to record an episode about synthesizers. We talked about the basics of sound generation, various enveloping and filtering techniques, sound design, the different fundamental approaches of sound synthesis, as well as a couple of classic synths. Rutger illustrated lots of approaches with samples from some of his many synthesizers.
