Microscopy and Its Historical Developments

The video tutorial explores the evolution of microscopy, starting from early magnification tools like the Nimrud Lens to modern microscopes. It highlights key historical figures such as Zacharias Janssen and Antonie Van Leeuwenhoek, who made significant contributions to the field. The tutorial also discusses the importance of resolution in microscopy and the major innovations that have shaped modern microscopy, including the development of the Phase Contrast Microscope and the Scanning Electron Microscope. The video concludes with a look at ongoing advancements in microscopy and their potential future impact.
