An understanding of quantum mechanics began in the early 19th century and had many contributors, including these well-known physicists.

Quantum Mechanics is the study of the dual particle-like and

wave-like behavior of matter

and energy. Image by Sbyrnes321

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.

Is nanotechnology better described by quantum mechanics or classical

mechanics?

Neither. Nanotechnology falls in between these at the mesoscopic scale.

At the mesoscopic scale, the properties of matter are governed by BOTH classical and

quantum mechanics.

What could be the implications of this?

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-0702976and the

Oklahoma Nanotechnology Education Initiative
