Microscopes magnify images so that we can see things that otherwise would be invisible with the naked eye. The most common type, light microscope, uses glass lenses to focus light and create a high resolution image. Some light microscopes collect light...

Although it takes the magnifying and resolution power of the electron microscope to visualize strands of DNA, grosser(larger) genetic structures such as chromosomes are, with proper staining, visible with the magnifications attainable with a simple...

Microscopes have been in use in various forms for more than 3,000 years. The first types were extremely simple magnifiers made of globes of water-filled glass or chips of transparent crystal. Ancient Romans were known to use solid, bead-like glass...
