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.

I wanted to make an episode on a topic from the history of science for a long time, finally it happened. This is an interview with Etienne Benson, professor of the history of science and technology, on the history of how people of the western world have been seeing, studying and explaining their environment. We talk mostly about his book, Surroundings, but also briefly about his current field of study.
