Several years ago, while working on a story about nanotechnology, I had the good fortune to come upon a friendly and generous Penn State professor of physics and chemistry, named Paul Weiss. (Paul now heads UCLA’s California Nanosystems Institute) Little did I know when we first met, that Penn State’s Weiss Group Laboratory was home to the mother of all scanning probe microscopes (SPMs), the renowned ultra-stable, extreme-high-vacuum, low temperature scanning tunneling microscope (STM), of which there are fewer than 10 in the world.
