La historia del microscopio

The video tutorial explores the evolution of microscopes, starting from early magnifying glasses mentioned by Roman philosophers to the development of compound microscopes by Robert Hook, who discovered cells. Anton Van Leeuwenhoek advanced microscopy with single-lens microscopes, observing bacteria and blood cells. The electron microscope, invented in 1931, offers higher magnification but cannot be used on living samples due to radiation. Traditional light microscopes remain essential for studying living cells.
