As time goes on, I grow more disillusioned with quantum field theory.

comment Visualizing vector-spherical waves
HI Jens, it doesn't seem to work. I am getting an error. First, I am using Sequence @@ CoordinateTransform["Cartesian" -> "Spherical", {x, y, z}] because I am using version 9. Then I am taking the fieldLinePlot out of the Table because I just want one frame. When I run it, I get a bunch of errors, the first one being NDSolve[...] nether a list of replacement rules nor a valid dispatch table followed by part specification errors. The code runs fine in the two examples that you linked to (pair of charges, and current). Any ideas?

comment Getting MemoryAllocationFailure from NIntegrate
My experience with this site tells me that people will ask you to show them what integral you're trying to do, and what output (if any) you get before crashing.. in both versions.

comment Visualizing vector spherical harmonics
This is fantastic. In v9, there is the built-in function CoordinateTransform that supersedes CoordinatesToCartesian and (I believe) the VectorAnalysis package as a whole. Soon, I will be multiplying with the BesselJ function, just as you predicted, and will need your help when I do!

@Mr.Wizard No, I never got it to work. But, I am still eager to get it to work. I have v 9.0.1

Thanks for reproducing; I have removed the bugs tag.
