i'm currently in garching, germany (near munich) visiting the Max Planck Institute for Extraterrestrial Physics and the offices of the european southern observatory (ESO). across the road from these intricately-designed buildings is the local university's school of Mathematik, Physik und Informatik.
inside of this building lives a wonderful set of slides, which provide an excellent escape from the office and bit of adrenaline-inducing fun when i feel sleepy in the afternoon!
you can pick up quite a bit of speed sliding down these slick tubes, and they provide a convenient measurement system beyond the end of the slide to tell you just how far you go! the best part is that the markings along the white line say 1, then the square root of 2, then 2, etc... nerdilicious.
every building should have a slide. weeeee!
