comment Exact difference between color scaling in ArrayPlot and MatrixPlot
@belisarius. Still an interesting thing to show, you ought to update the answer

comment Exporting to eps loses font/symbol information?
The issue is it wants to render the parenthesis using mathematica fonts. I don't see a work around. Can you see if you have the same issue with "pdf" (That should properly embed the font..).

Its really not clear exactly what he's after, I took it to be more about the look of the figure..

comment converting miles into inches from wolframalpha
Using precision implied by significant figures the "correct" answer is 16000. And how come .250005 -> 15840` not 15840.3 ?

comment How to replace all symbols except several?
In this example this works .. eq /. Cases[ Variables[eq] , v : Except[a | d] :> v -> 1 ]

comment Integration with mathematica?
This is an example where it is far easier to do the substitution by hand and feed theIntegral in terms of u to mathematica.

comment How to obtain all solutions for Cos[x] Cosh[x] == 1?
NSolve is about 10x faster than Solve // N . FindRoot is in turn 10x faster in this case since we can trivially feed it very close guesses..

comment Infinite sums with Boole and EvenQ
You probably know this but in this case you can readily handle it manually: Sum[x/x!, {x, 2, Infinity, 2}]. Search this site and you'll find a few examples of more complicated cases that cant readily be treated like that and unfortunately there is no general solution.

comment Exporting to eps loses font information
the problem is the fonts are not embedded and the result depends on whether whatever software you use for display has access to the mathematica fonts. For portability you should specify a universally available font such as Symbol.
