Zooming Into A Tooth

This video was put together using different instruments. Light microscopes are limited to magnifications of 2000 times. Electron microscopes can get magnifications of up to 2 million times. Scanning tunneling microscopy is a powerful technique for viewing surfaces at the atomic level.

Definitions: Apatite - any of a group of calcium phosphate minerals occurring variously as hexagonal crystals, as granular masses, or in fine-grained masses as the chief constituent of bones and teeth and of phosphate rock [From Greek apate, deceit (from its often being mistaken for other minerals).]
