Looks to me like something that would be better explained by a physicist.

... In other words, to answer your question, very hard.

But hey, if you want, I could prove that

N(α) is prime in Z => α is prime in Z[i],

that is, if the norm of a Gaussian integer is prime, then the Gaussian integer itself is prime. Anyone? Anyone?

(I just had our "midterm exam", so this stuff is just spilling out of me.)

So am I to believe that physicists are just smart arithmeticians?

Stated differently, did math people fail out of the physics department?

Math--the new communications.

I kid...I kid.

Actually, I often think about that. I always saw the (physical) sciences in kind of a hierarchy: Biology => Chemistry => Physics => Mathematics. As in, in each one you can, in a way, go "smaller" and "simpler" by moving to the next. I've always thought it interesting that, in a way, I could be considered not all that smart, since all I really understand is mathematics.

That's an overstatement, of course. And mathematics is not exactly on the same spectrum, as it can be applied to them all--and in just about any discipline--in different ways.
