comment Minkowski sum and product of 2D-regions
This works on reals but not on complex numbers: Reduce[Exists[{x1, x2}, x1 ∈ Reals && x2 ∈ Reals && Abs[x1 - 1] <= 1 && Abs[x2 - 1] <= 1 && x1 x2 == x], x, Reals] gives 0 ≤ x ≤ 4.

comment Finding closest point to implicitly defined curve
NMinimize[{EuclideanDistance[{x, y}, {x0, y0}], f[x, y] == 0}, {x, y}]?

comment What is the font that is most similar to latex fonts?
You know you can select the LaTeX font to match the ones available in Mathematica? For example, Times, Helvetica, Courier...

comment How to put an imported image in a Disk?
@Sektor: I find it unfortunate that many people respond to a request of the form "Please consider an alternative that is less unwelcoming and sexualized" with "I have the right to do what I want". Sure you do, but it was a request, not an injunction. Personally, I found it difficult to continue to use the Lena image in academic work after I was aware of the full picture it came from.

comment Converting a quantity to a decimal form
N[(5 coulomb)/(6 second)] gives me (0.833333 coulomb)/second. You could add /. {coulomb -> 1, second -> 1} at the end to get rid of the coulomb and second.

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!

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.
