There's an error in the MaTeXInstall Resource Function: evaluating it in Mathematica 12.3.1 (under macOS 11.5.2) causes a Join error.
Murray, The code in this demo requires version 12.3. However, that version of the CDF isn't yet incorporated into the Demonstrations build system. Once that is ready, I plan to republish with the CDF. I didn't want to make the author wait longer...
Murray Eisenberg and Rohit Namjoshi, Thanks a lot for all of your comments.
Thanks ! I will read it ... again, but I fear that it is quite complex to customize easily the numbering in notebooks ...
Hi. I have just made Surface Pro X with Windows 11 (build 10.0.22000.160) to run Mathematica 12.3.1, obviously in emulation mode. I tried BenchmarkReport[] and this machine got only 0.45, which is very low compared to 3.21 of M1 Mac running...
It's definitely the way the region mesh is generated using the region function. All the options of the resulting plots are similar with the exception of the PlotRange and PlotRangePadding. plotl = RegionPlot[regi, Frame -> True, AspectRatio...
What David Park writes is totally sensible: the built-in Mathematica syntax for graphics has definite limitations, especially for the newbie (and sometimes for the expert, too). As to his example with the disappearing Text given in the Epilog...
One point I was making is that Mathematica ought to have a built-in function, what I named ComplexParametricPlot, that uses a complex-valued function of a real variable as argument — without the user having to explicitly break the complex...

Today [I learned][1] that the solutions manual to Taylor's Classical Mechanics was aided by *Mathematica*, e.g. all the illustrations. Taylor's text was translated into many languages, and the German publisher made the complete solutions manual...
