faraday's, lenz's, momentum, conservation of energy, special relativity, newtons laws....
man it depends what you define laws to be. if u mean principles as well then there are alot more
just know the diagram and the basics of the experiement. basically braggs prooved the lattice structure within atoms when they fired electrons into a crystral. main principle: xray diffraction
The US election starts tomorrow. Am personally hoping for Kerry to win (mainly because he doesnt cheat in national debates unlike Bush, his stance on terrorism and he seems more trustworthy - see farenheit 911). Anyways im interested to hear other opinions of the issue. Feel free to vote in the...

For me and im sure for many Christians this is sufficient evidence enough
the greater the cross-sectional area the more current that can flow through the lattice without being impeded.
the likelihood of electrons colliding with impurities within the wire is reduced
