Get Good at Math with Me

Follow along while your average dude with a dayjob studies the math behind physics and engineering up through the early 1900s. This is a passion project but this material has some utility too. After the linear algebra part of the plan, I was able to create some 3d prototypes and understand some physics concepts that I never could have before. What did it cost me? Maybe a 50% reduction in my passive media streaming. Worth it! Personally I've been happier too.

Background: I have a STEM degree and shuffled off into the work world and have wished I learned this material more deeply. I came up with this plan over a few years. Depending on how you count I'm 1-2 years in at this point and it's been really rewarding.

Context: The curriculum is based on my personal preferences and the advanced applications that I look forward to being able to do. This first phase (~6 books) came out a lot like a strong physics or engineering undergrad math curriculum.

I'd love to have a couple people follow along or create their own personalized plan and tell me about it (discrete math, abstract algebra, proof based analysis route, whatever floats your boat)

I used the first edition of Marsden & Tromba at UCLA in 1976. The computer-generated plots were mind-blowing back then. The cover had a bluish image of clouds streaming over the Sierra Nevadas as viewed (I think) from US 395.
