comment What's the difference between this differentiation?
Oh, thanks. Didn't thought that the issue is in the (), not primes...

comment Power::infy: error using FindFit
If you want just a rough width of center peak, why not to use something like this: Manipulate[ Show[Rasterize[image], Graphics@{Red, Circle[p, r]}], {{p, {390, 270}}, Locator}, {r, 50, 100}]? It's just allows you to set width and position on eye.

comment Power::infy: error using FindFit
You don't understand what code you run... Can you just describe what you want to get? Width of peak? "Period"? Number of local maximums? I start to think that fitting this (also, this can be really looong... it's a non-linear fit for over 500k points) isn't a good idea.

comment Power::infy: error using FindFit
Can you provide all necessary code? That's not a good idea to people guess and ask what you mean...

And how do you load the image?

First of all, provide the Mathematica code.

comment Trying to solve simultaneous equations based on format found on official website
@DisplayName I just started in assumption that Mathematica is right and tried to prove there is no solution, but when found one - try to find, why Mathematica didn't found any.

comment Navier–Stokes equations
What have you tried? There is a simple example in the What's New in Mathematica 10, just plug into the Navier-Stokes instead of pure Stokes flow.

comment Problem with NDSolve in Mathematica 9 / 10
@Peter Can you also provide the PC configuration, time taken to compute this. It shuts down with "Out of memory" error.

It works for much larger numbers too.

comment WhenEvent “StopIntegration” problem
@jacob You're code works too, I think you just want to plot to 10 and it will plot, because it's an InterpolationFunction and can plot outside the defined range.

@chuy Added. Also, changing setting to show menu bar in the window have no effect.

@Öskå You've notice that the top bar included. I know about the global menu.

comment Negative number modular positive number ?
Uhm... What? It didn't evaluate it M10 or M9. Are you talking about Mod?

comment How do I format expressions so that replacement rules correctly apply to exponents?
@Susan Maybe you can use HoldForm somewhere earlier? I currently don't think of any way to convert a^2 to a a.

comment TrueQ returning False on true statement
I get TrueQ[Log[2.]/Log[8] == 1/3] as True in M9. And False for TrueQ[Log[2]/Log[8] == 1/3] in M9. Both returns True in M10.
