comment Could TiKz make a picture of a matrix with pictorial normal distributions?
Depending on the need for precision for the red lines, this can be done by TikZ \matrix very easily. Or you use a math-mode aligned environment and place little TikZ images in there.

comment Best way to illustrate Keplers 2nd law with tikz
How would you provide the coordinates optimally? Are they relative to the center of the ellipse or (as in your question and the answer) relative to one of the focus point? Or would you rather state two angles or one angle and a delta angle?

comment Best way to illustrate Keplers 2nd law with tikz
Very interesting. By the way, you can draw an ellipsoid arc just the same if you know the angles (from its center though): arc[start angle=<sa>, end angle=<ea>, x radius=<xr>, y radius=<yr>] (or (<sa>:<ea>:<xr> and <yr>)). I wonder if it would help to change TikZ’ coordinate system here with [x=2.5cm, y=2cm] then all ellipses and circles with radius 1 (and not 1cm!) would be stretched accordingly while polar coordinate are especially easy. Speaking of “unit circle” …

comment How to define a style for drawings using a special font and siunitx?
The default value for mode is math which means that it uses the math font. For some reason, siunitx chooses the text font for digits (even in math-mode itself). The mode option (which should be applied consistently with \sisetup) forces always text-mode. You need to go in more detail what you mean by “style template”. What (or who) should parse your numbers automatically? I am also missing the connection to TikZ here. Can you extend your question?

comment hyperbola curve and its arc
@giannis I have updated my answer with the “plain” version of your image (the arc is still not a hyperbola though). The other image shows the previous version with M lying in the middle of A and B.

comment How to define a style for drawings using a special font and siunitx?
You might link to the osifont. Regarding your problem, the text mode of siunitx helps with the font issue: \num[mode=text]{123456789,0}

Not that anything stands against saving the path in a macro (TikZ does support this) you can also save it as a style with the help of insert path: the saveuse path key. Might be helpful in some cases. :)

comment Drawing a straight line over a coordinate
No. The “pen” is still at (x1+x2,y1+y2), but further calculation of relative coordinates are done from (x1,y1). See my comments to Confused at + and ++ in TikZ. What I meant with my previous comment also is that (<c1>)+(<c2>) is not seen as one entity (but works for move-tos and thus as a path-start) but simply to different operations.

@MHaaZ Happens to everybody. :) (My first sentence is obviously a joke.) Interestingly enough, I couldn’t compile your example with draft or final.

comment hyperbola curve and its arc
What do you know about the “bow”? Is it a simple arc (fixed radius) or can it approximated by one? Is it sine? You can also plot it directly with TikZ.

comment Iterate over certain matrix cells
You need to use \pgfmathtruncatemacro otherwise you have a another . in the output: (m-1-0.0.south) (TikZ parses that as node name m-1-0 and anchor 0.south which it tries as an angle since no anchor is named 0.south. Besides that, there is a spurious { right before the relative coordinate and \itemtimesfour should be \itimesfour.

comment Can't use 'equal' in tikz-cd
There is no need to update packages yourself, manually or by removing old files first. Simply use the updating manager from your distribution. Take a look at How do I update my TeX distribution?
