This program introduces the concept of "nanospace" or micro-space, and reviews over 380 years of research into microscopy. Compelling photography of microscopic organisms fascinates us, and a visual scale, the "nano-gate," is introduced that helps to explain the concept of an object magnified a billion times its normal size. We journey into the atomic structure of the substances that make up our world and view atoms through the largest electron microscope ever built. The program concludes with the first view of the atom 20 years ago, and hints at things to come with the recent ability to "write" with atoms. (50 minutes)
