a close friend of mine used to tell me about these production Mathematica Notebooks he'd author at his company Coherence to do all these optical and thermal calculations with. It was a regular workhorse for him. A very long time ago I used to play around with Derive5 in my youth. It was the most affordable Computer Algebra System (CAS) of the time and I learned to program in that funky one liner programming language where I had to strip all the white space from my editor and always be careful to balance parenthesis. I should dig up those old files and upload them to my github. I've been actually meaning to reimplement those operations in a more modern CAS system and see if I can more densely plot these curves I was studying with some iso-arc-length families of exponentials about the point (0,1).
