Guitar Strings as Standing Waves: A Demonstration Michael Davis
This demonstration uses an acoustic guitar to produce three unique harmonic vibrations, each of which is representative of a standing wave and illustrates the concept of quantization.

Getting Close with the Instructional Scanning Tunneling Microscope Carl Steven Rapp
This state-of-the-art instrumentation is making it possible for students to actually view atoms in their own classroom. What is truly amazing, however, is that the ISTM can be set up and atomic resolution images obtained in about an hour.

How does the electron cross the node? Johnsen, Russell H.; Lloyd, Winston D.
Confusion arises from the assumption that the electron is a particle, when the model that produces an orbital diagram assumes that the electron behaves as a wave.

On the discovery of the electron Morrow, B. A.
Thomson's experiment resolved the controversy concerning the corpuscular or wave nature of cathode rays, while Millikan's experiment resolved the controversy concerning the continuous or discrete nature of electrical phenomena.

Atomic orbitals: Limitations and variations Cohen, Irwin; Bustard, Thomas
The three most widely used methods of arriving at a set of atomic orbitals afford respective hydrogen-like orbitals, self-consistent field orbitals, and various analytical approximations such as the Slater or Morse orbitals, all of which may differ greatly in shape and size from each other.
