What Are Your Side Projects?

In the summer months I make wood working projects that I sell at the local Independent Pharmacy The profit is donated to Meals on Wheels 50 years ago a friend who owned a pharmacy gave me this display box when all the soap sold Buy the Vintage 1971 Village Bath Handmade Soap Box Wood Advertising Display | GoodwillFinds[^] These were batch produced but very exact so I decided to make my own out of Half Inch Baltic Birch Plywood no glue just screws. they are stained various shades and 5 coats of my home made wipe on oil based Polyurathane Price is $30.00 to $50.00 based on the wood used and workmanship. As of now after 5 builds I can work to a tolerance of 1/32nd of an inch My other product was to copy this box design with no screws and just glue https://www.youtube.com/watch?v=b4-KtUUtRvY Built a few workbenches but where I live everyone is a DIY'er so sales not so good plus they are massive 60 in by 36 in and 36 in tall with twin screw tail vise made with 10 year old red oak 30 in wide jaws. They tip the scale at 250 lb

Writing a program to calculate fractals rigorously (i.e. being certain that a point is inside, outside, or "unknown" as yet) Writing a full implementation of the IEEE 754-2019 Floating-Point Standard, with the intention of expanding it to higher-precision types Learning all the Physics that I missed out on by becoming a software engineer Converting the WINFRACT (FRACTINT for Windows) program to run on Win32 or Win64

may i inquire which Physics topics / authors you are studying assuming of course you have time for such whilst writing great code .

I've always wanted to actually understand General Relativity. The undergraduate degree that I did in Physics only covered Special Relativity. I've been going back to the original papers - Einstein, Minkowski, etc. for the physics, and studying Tensor Analysis from a few different books (M.L. Boas - general math, A. Lichnerowicz - Tensor Calculus, ...). At the rate I'm going, it will probably take me a few years to thoroughly understand the subject, but I'm in no hurry... :) Ditto for everything else. These are hobbies, so I have no deadlines.

do you have a copy of Gravitation (book) - Wikipedia[^] i use mine as a door stop as i have yet to finish Classical Mechanics (Goldstein) - Wikipedia[^] . it required several readings with an overly lengthy interruption in order to begin to understand virtual displacements as utilized in deducing LaGrange's equations . i have to read it again to consider if my understanding is correct . re/ tensors i viewed a few years ago a superb YouTube series on the subject . unfortunately i no longer have the link . also do you have a copy of "Spacetime Physics", Second Edition by Edwin F. Taylor and John Archibald Wheeler . i also have a oopy of Einsein's GR paper . i did not find it helpful . the references to Mach and his ideas i have yet to understand . i wish you great success in this fine pursuit .

I have a copy of Gravitation, but not the other books. I have a copy of Einstein's GR paper, and am trying to collect the papers that Einstein referenced (and in some cases - the papers that they referenced). The problem is that many of them are available only in German - and I don't read German.

of course it may be useful to steady the original papers . however it seems to me you are eschewing the modern texts . if so i do not understand why . don't forget papers published in scientific journals are terse and not meant to be edumakational exempli gratia Einstein's original GR paper to now a 1,000+ page tome by Wheeler et al . also i am a believer in multiple authors / texts . by the way my undergrad physics instructor was kind enough to give to me the gift of a Xerox "orignal" copy of Michelson's "SPEED OF LIGHT" notebook complete w/ tea cup stains and his fine penmanship .

I didn't say that I intend to neglect modern treatments of the subject. I just want to start from the original papers, and take it from there. I know, for example, that in order to understand GR I must review Tensor Analysis, study Differential Geometry, etc. before even trying to tackle Einstein's papers, to say nothing of later texts.
