you can also use QuantityMagnitude to get the value out.

or In[647]:= UnitConvert[Quantity[1, "PlanckConstant"], "eV*s"] Out[647]= Quantity[4.135668*10^-15, "Electronvolts" "Seconds"]

comment Numerical value of physical constants Mathematica 10
what would you like the result to be, i.e. which units should it be with respect to?

comment Integral too slow and with conditionals
use assumptions Integrate[x/(x^2 + y^2)^(3/2), {y, -a, a}, Assumptions -> (x | y) \[Element] Reals && x > 0 && a > 0]. This is likely a duplicate, but I can't find which one.

comment Why does Fourier give a shifted frequency?
@xslittlegrass, actually it was the second part in the answer: "in addition, the discrete fast Fourier transform assumes periodicity."

comment How to know at which point of a calculation I am while using Table
Table[n = i; Pause[1]; foo[i], {i, 0, 10}]; Labeled[ProgressIndicator[Dynamic[n], {0, 10}], Dynamic[n], Right] for overkill

comment Simplify with Assumptions Sqrt[(expr)^2]
PowerExpand[Sqrt[(x - y + a b c)^2]] perhaps, with all of the caveats of PowerExpand.

comment How can I tell how much memory is taken by an expression?
What do you get from evaluating Developer`$MaxMachineInteger? I suspect this is a 32-bit thing.

comment How to change a parameter dynamically inside NDSolve
Are you sure the condition x'[t]==0 actually occurs? Look at DSolve[{x'[t]+(x[t]-\[Lambda])==0,x[0]==0},x,t]

comment Can ParallelDo speed up a counting problem?
This might be too far from what you want, but maybe evs = Table[ParallelSubmit[Boole[RandomReal[] > 0.5]], {10000}]; and then Total@WaitAll[evs]

comment Automatically highlight certain cells
@Kuba I am quite sure it won't, (for example if the cells you want to highlight in this manner are not connected) but this should show how one could use Item and the options it takes to style as wanted. Personally I wouldn't use a frame and rely on background.

@george2079 I agree, I was trying to coax more information if possible.

Is this closer? Array[Integrate[Symbol["f"<>ToString[#]][x],{x,Symbol["x"<>ToString[2#-1]],Symb‌​ol["x"<>ToString[2#]]}]&,4]
