The History of the Microscope

The video explores the evolution of microscopes, starting from early mentions by Roman philosophers to the significant contributions of Galileo, Robert Hooke, and Anton van Leeuwenhoek. It highlights Hooke's discovery of the cell and Leeuwenhoek's observation of live cells. The video also covers the invention of the electron microscope by Max Knoll and Hans Rusker, which allows for much greater magnification but cannot be used on living specimens due to radiation damage.

• Robert Hooke

What was a major advantage of Leeuwenhoek's single-lens microscopes?

• They used a beam of electrons
