Six years ago, in episode 150, Jochen Liske of ESO told us about the Extremely Large Telescope that is currently being built in Chile. This episode is a continuation (which is why this is a kind of bonus episode labelled as 150.5) in which Thomas Pfrommer tells us about how to control the optical path of this monster telescope: the 39 meter, 798-segment main mirror, plus the four additional mirrors involved in bringing the light to a stable and sharp focus. I recorded this episode mainly to fill in some “gaps” I needed for the book chapter on telescopes.

Vor über fünf Jahren hatten wir in Episode 150 über das ELT berichtet, ein gerade im Bau befindliches 39 m Teleskop mit einem Spiegel aus 798 Segmenten. In dieser Episode sprechen wir mit Thomas Westerhoff von Schott über den Herstellungsprozess dieser (und anderer) Spiegel für die Astronomie, und das dafür verwendete Material, Zerodur. Zusammen mit den nächsten Ausgabe zur Steuerung des ELT sind habe ich diese Episode auch deshalb gemacht, weil sie Teil des Buches sein wird.

Im November habe ich das Landeskriminalamt Baden-Württemberg in Stuttgart besucht um mich dort zu Kriminaltechnik schlau zu machen. Nach einer kurzen Einführung zu den Aufgaben des LKA haben wir drei Themen genauer betrachtet: Daktyloskopie (mit Hagen Gunzenhauser), Waffen und Ballistik (mit Volker Schäfer) sowie DNA Analysen (mit Rasmus Förster).

The F-14 Tomcat is one of the most iconic fighters, certainly among its generation. In this episode we talk with Nick Pirnia about the aircraft’s development and history as well as about flying it with former pilot Okie Nance. The aircraft is also available in the DCS flight simulator and the third part of this episode is a conversation with the development team from Heatblur about how to implement the F-14 in DCS; if you haven’t yet, check out some of their videos, this thing looks unbelievably realistic!

An important consequence of the warming of the planet due to climate change is that the frequency and/or severity of extreme weather events will increase. But how can we tell whether a particular event can be attributed to the changing climate? Would it have happened in “normal” climate as well, and if so, how would the event have been different? This aspect of climate science is called attribution science, and the guest of this episode, Friederike Otto is a pioneer in the field.
