Exploring the Evolution of Microscopes

The video provides a historical overview of the microscope, starting with the 1590s experiments by Hans and Zacharias Jansen, who discovered that multiple lenses in a tube could greatly enlarge objects. In the 1660s, Robert Hooke used a crude microscope to study various objects and named cells. Anton van Leeuwenhoek, in the 1670s, built the first practical microscope and was the first to describe bacteria. Microscopes have since evolved, with significant advancements like the electron microscope developed in 1931 by Ernst Ruska and Max Knoll, capable of magnifying objects up to 10 million times.
