nice work. I would have removed most of 'PART 1: PHYSICAL CONSTANTS', 'PART 8: APPLIED FIELDS', 'PART 18: ELECTRICAL', and some of 'PART 99: CONVERSIONS'. "all-in-one" math seems enough :). Other stuff seems arbitrary and leaning towards physics (which could have its own giant book).

I'm biased as I'm an EE, but I'd say that the Laplace transforms within the Electrical section are firmly in the realm mathematics, so keep them. It just so happens that they are only really useful in the domain of digital signal/control processing, and I think to get the true form or radioactive decay(?) though I may be mistaken. I'd put it next to information on Fourier transforms. The circuit theory may be a bit unnecessary though I agree.

One day , I'll make an Anki version of this.

Just start with one small section :P

Last year, when I was in high school, I turned most of my math (and physics) textbook into an Anki deck :D

It's really good, especially when the final exam covers +4 years of mathematics.

I remember for Maths, Further Maths and Computing A-Levels typing in mini programs for everything into my TI-85, from stats to bubble sort or curvature. It took so long typing that on a numerical keypad I could remember everything and no longer needed it. Still, a good exercise in basic programming and not unlike remembering from a flashcard deck.

Four years later in banking, I discovered the entire industry does the same, but in Excel. Enjoy your studies!

I actually can't tell if that was an intentional "margin" joke, or if the author is just bluntly stating a fact about Wiles' proof... EDIT: Nope, probably intentional. The author doesn't say something similar for any other proof based on a quick CTRL+F :)

Fermat wrote that in the margin of his book Arithmetica that a proof existed, but there wasn’t space in the margin to write it. It took Wiles 385 years to find a proof, and it won’t fit in a margin. https://en.m.wikipedia.org/wiki/Fermat%27s_Last_Theorem That’s the allure of the theorem; that a simple unknown proof may exist.

Yes, I remember when news of his proof broke, being disappointed at how voluminous and obscure (to someone like me) it was. I'd been hoping for something I might be able to get my head around. (Hard as it was, I don't think Wiles spent 385 years coming up with it btw!)
