comment Better way to binarize an image
+1, I would also suggest a bigger radius so you don't get the extra noise in the middle of the pieces.

comment How to sort colors properly?
The article also describes how Mr. Gray created the histograms you like, so you could try doing that.

comment Better way to binarize an image
From the looks of your output image (please repost the original though) you should try LocalAdaptiveBinarize.

comment Expand the plotting range
The problem is not with Plot but with the cube root itself. See Finding real roots of negative numbers.

comment InterpolationOrder 2 or more in ListLogLinearPlot
Once you have interpolatingFunction why not directly call LogLinearPlot?

comment Simple ways to implement vector dilation
I didn't post an answer because I don't have access to Mathematica right now, so I had no idea if my suggestion would actually work!

comment Simple ways to implement vector dilation
Something along the lines of ImplicitRegion[RegionDistance[polygon, {x, y}] <= r, {x, y}]?

comment DiscretizeRegion of ImplicitRegion too small
Does it help if you use the RegionBounds of the previous region to set the bounds on x and y, instead of fixing them to {{x, 0, 2}, {y, 0, 2}}?

comment How to fill the space outside of an image after rotating it
You could also try Padding -> "Fixed" or Padding -> "Reversed" to repeat the pixel values of the image itself.

comment MeshFunction at azimuthal angles for RegionPlot3D
Try using the equation of the azimuthal plane: MeshFunctions -> {Det[{{#1, #2}, {Cos[t], Sin[t]}}] &}, Mesh -> {{0}}, where t is the azimuthal angle you want.

comment How do I create a triangulated surface from points?
Maybe your code is computing the total area of a two-sided surface?

comment FindShortestTour 3D data
Formatting tip: select the code and press the "Code Sample" button on the toolbar (it looks like {}) to format it as a code block.

comment Mathematica equivalent of `qnorm` or `invNorm`
You could also use InverseErf, but that's cumbersome too.

comment NIntegrate of surface area of intersecting spheres yields zero
Doesn't this method also count the area of a sphere lies within another sphere, which @Fred said he doesn't want to count?

comment Defining a 2-variable function over voronoi diagram
You don't need to have computed the Voronoi diagram beforehand, you can just use Nearest: mathematica.stackexchange.com/q/17075/484

comment Enforce graph symmetry
Can you explain what your code is computing? What does the Select[bb, # <= nn &] restriction do exactly?

comment Want to add a legend to 3D plot made by combining three plots with Show
Why not just put them all in a single plot? Plot3D[{Cos[x] Cos[y], -(x - Pi/2) (y + Pi/2), (x - Pi/2) (y + Pi/2)}, {x, -5, 5}, {y, -5, 5}, PlotRange -> {-1, 1}, ClippingStyle -> None, PlotLegends -> "Expressions"]

comment How can I generate and randomly assign color to annular sectors?
Your annular sectors look very polygonal to me... But the colour scheme you picked is very pretty.

comment Equation solution using minimization
Can you elaborate on what properties of the function make it impossible to use ContourPlot?
