Microscopic Life: Seeing Microscopic Life

The video explores the microscopic world, starting with the observation of organisms in a drop of water. It discusses the history of microscopes, beginning with the invention of the compound microscope in 1590. The video explains how compound light microscopes work and their magnification capabilities. It then introduces electron microscopes, which offer much higher magnification, and describes their use in studying cell structures.
