1. Basic Microscopy

Microscopy is a scientific field that uses microscopes to view objects too small to be seen with the naked eye. It's essential for observing cells, microorganisms, and materials at a microscopic level. Light microscopes use visible light and lenses, while electron microscopes use electron beams for higher magnification and resolution. Both are fundamental tools in biology, medicine, and materials science.
