comment Is it possible to do vector calculus in Mathematica?
Your continuity equation is wrong. The quantity n is a scalar, not a vector field. No wonder the result looks horrible. If you fix that it will look less so.

comment Citation and Bibliography mac with Mathematica 9
I agree - seems almost as if they still see Macs as an insignificant platform, given that the Frontend still uses Carbon, and "Save as Quicktime" has recently been removed from the menu bar, ... the growing Mac user base won't like it.

comment Where is the “Insert > Citation> Bibliographical Reference” Command?
That's an uncommonly long delay for a response. Maybe this means their lawyers got involved... so I better watch what I write...

comment Symbolic derivative of $n$-term product
I think I covered that in my intro. It doesn't apply here.

comment Symbolic derivative of $n$-term product
That's right - I simply worked with the OP's statement "I really don't care about the derivative per se," where the prefactor becomes irrelevant to the extremization.

comment Plot[] breaks behavior of custom data handling function - Recursion
By the way, in case you're really interested in something like what your example does, maybe take a look at MovingAverage

comment Plot[] breaks behavior of custom data handling function - Recursion
Your problem isn't recursion, it's the fact that array indices have to be positive integers and Plot assumes a continuous variable.

comment Plot[] breaks behavior of custom data handling function - Recursion
This (+1), or ListPlot seem to be the most appropriate solutions. Or one could stick with Plot and replace ProcData[x] with ProcData[Floor[x]].

comment Reap and Sow From NDSolve solution
It should also be pointed out that the usage of Sow in the question is incorrect. The second argument of Sow is a tag to identify the object for later use, not a range specification as seems to be implied in {x, 0, 30}. In fact because of this error I think the question is probably not going to help anyone looking for Reap and Sow...

comment Using mesh for a single function inside Plot
This doesn't use Mesh at all, in contrast to what the question title states.
