Room at the Bottom

My latest Coursera course is in Nanotechnology, usually defined as the science of materials with features in the 1 - 100 nanometer scale. For comparison, note that a small bacterium is 2000 nanometers, and a small virus about 20 nanometers, while a single neutral atom can be as small as 0.03 nm. Feature sizes in modern integrated circuits (like CPUs) are roughly in the middle of the nanoscale these days.

Some might notice that my title is borrowed from Feynman's famous talk called There's Plenty of Room at the Bottom, which is often considered the founding document of nanoscience.
