You have an ampersand in the wrong place. You need SortBy[# , #[[2]] &]&

comment Adjusting contrast of a color scale with ListDensityPlot
Have you tried different colour schemes? Maybe "Rainbow" or "BrightBands". Have you tried a gamma correction instead of a log? Have you tried a ListContourPlot and specify the contours you want?

comment Nested mapping of a function
They are not the same if you define something for f. Try it with, say, f = #+1&.

comment Where does this gray solid line come from in plot?
I have expanded my comment into an answer. I agree that it is a good question. The simple answer is just one of those things you remember with experience.

comment Fractals or other patterns in the quadruple linked pendulum
You could plot any plane through your four dimensional parameter space. You can also get three dimensions by creating a animation. Mathematica can allow you to manipulate the parameters to find interesting results. If you would show your code I'm sure we could make it fast enough to make these suggestions practical.

You could just put a /. Line -> Tube on the end of your plot.

I recommend looking into the Select and Cases functions.

comment How To Replace $\rightarrow$ by $==$ in Mathematica's Output when using Solve
You do just like you said in the title. Use a rule on the rules: Rule -> Equal.

comment NonlinearModelFit indeterminate or not a list of real numbers
You can put in conditions on the parameters to avoid non-real numbers, but you're going to have trouble no matter what you do. You have a Log[A3 x] in there and you are trying to fit to both positive and negative x values. So you are always going to get a complex result at some point.
