The History of Microscopy

The video tutorial explores the evolution of microscopy, starting with early magnification tools like the Nimrud Lens and progressing to the invention of the compound microscope by Zacharias Janssen. It highlights key advancements made by Antonie van Leeuwenhoek and Robert Hooke, who improved the microscope's design and functionality. The tutorial also covers significant 20th-century innovations, including the phase contrast and electron microscopes, which have greatly enhanced our ability to study microscopic organisms. The video sets the stage for further exploration of microscopy techniques in subsequent tutorials.
