Crazy amateur studying Aeronautics learning Physics (Wanna know how much I love Physics?). I spend most of my time in the internet, especially Stack Exchange (Wanna know how Stack Exchange changed me?). Then, I'll be lurking in facebook, Twitter, Google+ and my new blog. When situation forces me to get up from my PC, I juggle...

comment Would magnetic flux be necessary for analogous systems?
@Floris: I've revised my question with a sample of the differential equations which obviously show my confusion :)

comment Would magnetic flux be necessary for analogous systems?
Dear @Luboš: Well, I'm able to understand the equivalence for the $F\to V$ system quite well. Can you specify which of those entries disagree? In his lecture, Feynman addressed only the voltage-analogous system (which I understand just fine). Only the latter entries (for the current-analog) are confusing me (which wasn't addressed by Feynman)

@karthikeyan: The author has accepted the answer, which implies that he's convinced ;-)

comment Why does a system try to minimize potential energy?
Shouldn't the conversation be other way around? Physicists develop theories based on experiments, and don't really ask "why" questions (that applies to physics students too) as they're aware of the fact that "why" questions can't be answered! Only beginners find it hard to interpret.

comment Black-holes are in which state of matter?
(sigh) Blackholes aren't infinitesimal. They're finite in size, and have a finite mass. You're talking about the center of the blackhole (the singularity) where the laws break down while I'm talking about the entire blackhole!

comment Black-holes are in which state of matter?
The text you've quoted mentions about the mathematical singularity which isn't matter (yeah, but) the question which I intended to ask then, was about the form of matter that makes the black hole itself, not the singularity!

comment NO Uncertainties for particles in their own frames!
The uncertainty principle doesn't mean that particles jiggle back and forth. Instead, it places a fundamental (quantum mechanical) limit to the precision of our classical instruments. And, we're in a perplexed state of mind, that we've already been confused by the particle-nature and wave-nature of the so-called particles. In such a state, how can we imagine a frame for such an inconceivable thing?

comment Why can't an excess of electrons or holes by themselves cause current flow?
In addition to what others said, I don't think the definition of electron holes work out for usual metals. A hole is just the absence of electron in an otherwise full valence band. In your case, the valence band is full only because of the excess electrons and holes.
