This is a bummer - headed to Berlin for the first time in a few weeks and hoped to visit. Any recommendations for similarly geek-oriented side trips in Berlin?
Technikmuseum [0] has many different technology-related exhibitions. And the Spectrum (separate building) has a lot of physics- and science experiments you can actively try out. Loved it as a kid.
Not sure if it counts as geek-oriented but take a look at the guided tours by Berliner Unterwelten [1]. They are really good. (Tours in English are available)
