Suppose you a have superconducting loop connected to a 9V battery. What is the current through it? With a resistance of 0Ω, V = IR gives ∞. I don't think that can be right... If it were, V=\frac{I}{nAe} would give an infinite velocity... Does that equation even apply to superconductors?

What kind of mathematical disciplines/fields take part in what's called "applied mathematics"? As far as I know, it's Differential Equations, Calculus, Statistics and Linear Algebra. What other fields are there? I'm sure there are some others.

What are the differences, if there are any, between these degrees? By differences what I mean is what classes are different in obtaining one from the other? Why do some universities give one and not the other? What possible drawbacks are there between each degree in terms of future employment...
