Microscopy: Too small to see
|
What is a nanometer? A nanometer is one-billionth (that is 1,000,000,000) of a meter. So a hair is 100,000 nanometers across. That's really small. Atom Transporter: How can you move atoms around? Atomic Force Microscopy: The atomic force microscope can create images of really small things by "feeling" with a nanosized tip Atom Manipulation: Scientists can move single atoms from one point to another with nanometer precision. The World's most powerful microscope: The world’s most powerful microscopes don’t see things with light or even electrons. The world's tiniest switch: To make computers faster and faster, scientists and engineers have had to make the transistors smaller and small. |
