6. Updated September 2011 Matter and energy behave as both waves and particles. Matter at the quantum scale behaves differently in several ways: At the quantum scale, you cannot observe both the speed and the location of a matter and energy at the same time. The behavior of matter and energy at the quantum scale is often counter-intuitive to classical physics.

7. Updated September 2011 Is nanotechnology better described by quantum mechanics or classical mechanics?

8. Updated September 2011 Neither. Nanotechnology falls in between these at the mesoscopic scale. cc by Guillaume Paumier Image cc by Collin M.L. Burnett Atomic Scale Mesoscopic Scale Macro Scale Quantum Mechanics Nanotechnology Classical Physics

9. Updated September 2011 At the mesoscopic scale, the properties of matter are governed by BOTH classical and quantum mechanics. What could be the implications of this?

10. Updated September 2011 This module is one of a series designed to introduce faculty and high school students to the basic concepts of nanotechnology. Each module includes a PowerPoint presentation, discussion questions, and hands-on activities, when applicable. The series was funded in part by: The National Science Foundation Grant DUE-0702976 and the Oklahoma Nanotechnology Education Initiative Any opinions, findings and conclusions or recommendations expressed in the material are those of the author and do not necessarily reflect the views of the National Science Foundation or the Oklahoma Nanotechnology Education Initiative.
