Picturing the future can be fascinating. An exhibition on the development of science fiction in Germany at a Bonn museum traces this fascination. Here are some of the highlights.
Since the start of the technological age, science fiction has acted as a reflection of the public's fascination with the future and inspiration for scientists to develop new technologies.
