Thanks Prologue! No, not crazy units really. I should have mentioned I was using gaussian units. The equations are much more compact that way.
So, I figured it all out. The cross product is in fact a scalar, which you can get by a few methods, some of which involve some shading dealings with...
Hi, I'm having a bit of a hard time stumbling over the concepts of the following problem:
Homework Statement
In Electrostatics:
How do you modify the div and curl of the electric field from 3D to 2D?
What are the 2D and 1D versions of Coulomb's Law?
Homework Equations
In 3D (sorry, no latex...
We have micro tractor beams that can trap and move dielectric particles around the size of bacteria. They're called laser tweezers and optical traps. Technically, you can make one with pretty much any kind of laser, even a laser pointer, and an objective. They're not big enough to trap any...
Yeah, "overlap" is a bit of a fuzzy word. I'm for the already-mentioned overlap integral as the most correct response. I'd look into concepts like bose einstein condensation (bosons do not obey pauli and his famous principle). An even fuzzier notion in regard to "matter overlap" is tunneling...
