Nanotechnology researcher Dr. George S. Tulevski is asked to explain the concept of nanotechnology to 5 different people; a child, a teen, a college student, a grad student, and an expert. Nanotechnology is the study of objects at the nanoscale (between 1 and 100 nanometers in size). Objects at this size have a peculiar set of properties that differ from objects at the macroscale. Dr. Tulevski does his best to succinctly explain this phenomenon, adapting his language and tone along the way.
