Where did you get the idea for your most recent book?
My new book "Professor Kompressor out of this world" was inspired by two things. First of all, the title - given my day job as an astrophysicist it seemed inevitable that I had to write space adventure at some point and once I thought of the title... that was it. The second key moment was when I had the idea of how the Professor could make the warp drive work. I am not going to reveal anything here, but I think the solution is very clever.
