Sonar
Would love to learn more about Sonar. Since the Hall effect sensor converts a magnetic field into electrical form, and piezoelectric crystals convert pressure changes into electrical form, could that be put to work for a transducer? And is it Snell's law or Fermat's principle that governs light trav...

Stir this in to the recipe: Tunnel Ionization Tunnel ionization is ionization due to quantum tunneling. In classical ionization an electron must have enough energy to make it over the potential barrier, but quantum tunneling allows the electron simply to go through the potential barrier instead of g...

Put These Together...And What Do You Get?
Quantum Hall Effect
(Hall Thruster)
Goldstone Boson
(Mexican Hat)
Broken Symmetry, of course
Reflex Klystron
Don't Forget Maxwell's Equations
Hey out there, thanks for the Scalar hint. (Just took a few hours).

Circumhorizontal Arc
For consideration as APOD. Taken in Blue Springs, Missouri on July 9 2007. Maybe NASA can also tell me why a cloud with ice particles was so low in the atmosphere on this hot summer day.

How to Submit Picture?
I just can't seem to figure out how to submit an image for APOD...I feel silly, I must be missing something pretty obvious!
