Episode 98 goes to the Netherlands. There is something remarkable about the Dutch when it comes to glass lenses and scientific tools. Maybe Hans Lippershay invented the telescope. Maybe it was some kids in his town. Or maybe it was one of two other guys who seem to have come up with the idea at the same time and place.

And as far as microscopes go, a dutch man named Antonie von Leeuwenhoek got obsessed with microscopes. He is remembered as the father of microbiology.
