Abstract:
The optical microscope is probably the only scientific instrument that children are familiar with, and possibly the only one that can be bought in toy shops. At school, most of us looked into such microscopes with great expectations, hoping to see unimaginable details of a leaf or dead fly. Often we were disappointed that we could not see more. Where were all those atoms and molecules that everything is supposed to be made of? If we complained to the teacher, we were usually told that one cannot see things that are too small in an optical microscope. Until recently the teacher was right, but not any more.
