I am actually studying special relativity and found Jupyter Notebook plus some simple plot helps a lot. I did search Common Lisp as reading python code is hard. A mess for the one doing Lorentz trnasformation. End up I have to do it myself. This is different I suspect if it is in common lisp as it usually can be read, understood and use. Sadly for simple realization for example the twin paradox without acceleration (3 astronauts handing over clock info instead of using acelearation). It is not there. And doing graphic … and simple wedge. Sadly. May be someone here can highlight some sites for this and that. For chapter 14 I wonder whether a Jupiter notebook (which can do Tex if using Matplotlib … have not tested it as I used texshop and screen capture from Matplotlib instead).
