comment Avoid unnecessary truncation
You use use the same $PrePrint command, like this: $PrePrint = AccountingForm[#, DigitBlock -> 3, NumberSeparator -> " "] &; I just do not know how to make the separator small.

I think it will be good idea to close this question, since it has an answer already, and post a new question specific to "How to make $PrePrint use AccountingForm with small space for Block separator". This way it will be more specific question, or rename the question, edit as needed.

comment Avoid unnecessary truncation
I think you can using MakeBoxes, but I am not good at that. AccountingForm allready supports setting of DigitsBlocks. Try this: AccountingForm[0.34*60000000, DigitBlock -> 3, NumberSeparator -> ","] But I do not know how to tell it to use small space for separator. Using NumberSeparator -> " " will make the space too large.

You can use 0.34*60000000 // AccountingForm I do not know now to set this to be automatically applied to each number printed. see mathematica.stackexchange.com/questions/20373/… (I think the answer you want is there, just saw it)

comment Why does Mathematica not seem to know that $i^x$ cannot be equal to $0$?
On V 9.01, I get Simplify[2^x a == 0] as 2^x a ==0 not a==0 ? screen shot !Mathematica graphics

comment Differential equations: Solving a singular/nonlinear ODE using NDSolve
According to Maple, the system appears to be singular at the left point. It actually solved it analytical, with the trivial solution $y=0$. screen shot !Mathematica graphics (so basically your system is not well formed to solve) it suggested a mid-point numerical method. But I do not know now how to apply this in Mathematica NDSolve and it is there...

comment Setting up and solving system of equations
@SvendTveskæg Expand is not needed. I was doing something else before and left it there. Yes, you can remove the Expand command. It does not do anything. Will update. Thanks.

comment How do I evaluate a symbolic integral involving Hermite polynomials?
Even after the correction in exp to Exp, it is not possible to get analytical solution. !Mathematica graphics after about 3 minutes trying... also Maple 17 not able to do it. To help find such syntax errors, I always look at the equation for the green colored symbols (or is this blue colored? I always mix green with blue). If the symbol is not black colored, then it means Mathematica does not know about it. You could have seen that exp was green colored, this means Mathematica does know about it.
