This podcast is drawn from the "Virtual Lab" of WeCanFigureThisOut.org. This Virtual Lab uses 3D virtual reality animations to explain electronics, microelectronics and nanotechnology. This podcast explains how scanning tunneling microscopes (STM's) work. STM's are one the nanoscientist's best tools for seeing individual atoms.
