Rules for Extra Credit: (due Dec 23)

A 3- page paper (excluding pictures and references), written in word (12 point letters), send to me by email on a “modern physics” topic.  Below are some suggestions.

Included should be:

-          2 references to the literature (popular sources such as Physics Today, American Scientist, and Scientific America are allowed).  References should be less than 50 years old. 

-          2 references to the textbook: Modern Physics by Tippler and Llewellyn (which can be to parts we did not cover including Chap 14).

-          Correct spelling and grammar.

 

Suggestions:

·         Frozen Light:

Scientific American, Volume 285 Number 1 July 2001 pp.66-73: Slowing a beam of light to a halt may pave the way for new optical communications technology, tabletop black holes and quantum computers.

·         Quantum Electronic Devices:

Physics Today 54, 2000, 2001, pp 46 Nanometer-scale islands that form spontaneously on a semiconductor substrate have atomlike properties and potential applications in optical and optoelectronic devices,quantum computing, and information storage. http://www.physicstoday.org/pt/vol-54/iss-5/p46.html

Physics Today 43, 1990, page 74 (by F. Cappasso and S. Datta)

 

·         Diamagnetic Levitation

American Scientist, Sep-Oct 2004 (by Ronald E. Pelrine) Known since the 1930s, a simple technique for suspending objects magnetically is just now finding practical application.

·         The Fundamental Physical Constants

Physics Today, August 2002 (by P.J. Mohr and B. N. Taylor)

·         Laser Light

Scientific American, September 1968 (by A. L. Schawlow)

·         Gravity Waves:

Science News, Jan 8, 2000, p 26: Excellent article about gravity wave detection using a two-arm interferometer similar to that used in the Michelson-Morley experiment.

·         Divertimento for Strings

American Scientist, Nov-Dec 2005 (by Jean-Pierre Hebert) String theory proposes a way of uniting the quantum and relativistic physical theories that have resisted, since Einstein's day, all efforts to knit them into a unified theory http://www.americanscientist.org/template/AssetDetail/assetid/47363
