You will have an extra week to answer this vexer (i.e. a total of 2 weeks) since I will be gone beginning this coming weekend for the PAC05 conference...
This is a good link to have to dispel any myth people might have that physics produces no "useful" applications. http://www.physics.ucla.edu/~ianb/history/ Zz....
Zapper, thanks for the helpful link. I really learned some things :) But I did notice an error in the article. It said: "This discovery of the electron by...

You are correct on BOTH counts! If there is a contact e-mail on that site (and I think there is), may I suggest you write an e-mail to him and correct both...

Hi Dara, Good questions. De Broglie's relation came before Heisenberg's. It is basically stems from a hypothesis that there are "matter waves" and the ...
