just start with the Feynman undergraduate lectures (listed). The easy-mode of that is "Six Easy Pieces" (read it on kindle) which are the easiest 6 lectures.

At some point you'll need math, I recommend https://www.amazon.com/No-bullshit-guide-linear-algebra/dp/0... (I actually started here), and for calculus, "No BS Guide to Math/Physics" by the same author. These books both include a review of high school math (i.e. trig) which i needed. For DiffEq I currently recommend Logan's "A First Course in Differential Equations", this is where I am now and I found this the most gentle after trying several textbooks recommended from r/math. Context: I am an adult with an engineering degree from 20 yrs ago.

i read your book cover to cover it was amazing

If they have showed any interest in math and/or physics, you should consider getting them my MATH&PHYS book: https://www.amazon.com/dp/0992001005/noBSmathphys it's very popular for programmers.

I also have a book on linear algebra, which would be good for people doing more machine learning or data sciency stuff: https://www.amazon.com/dp/0992001021/noBSLA

Both books are perfect for math haters, since they start out with a review of high school math.

Depending on your background and intentions, you might like:

Savov: https://www.amazon.com/No-bullshit-guide-linear-algebra/dp/0...

Strang: https://www.amazon.com/Linear-Algebra-Learning-Gilbert-Stran...

Klein: https://www.amazon.com/Coding-Matrix-Algebra-Applications-Co...

I think the pacing and exercises in the above Strang book are great.

There is the No bullshit guide to linear algebra by Ivan Savov.

Could have been us — we have a "free PDF if you email me proof of purchase for print" policy for all our books[1,2,3]. Currently, I handle this manually via email, but I wish this was more automated somehow (e.g. shopping cart plugged into print-on-demand fulfillment API + digital delivery of eBook in all formats).

If you're looking for something very basic (high school and calculus), you can check my book No Bullshit Guide to Math & Physics: https://www.amazon.com/dp/0992001005/ Extended preview here: https://minireference.com/static/excerpts/noBSguide_v5_previ...

There is also the No Bullshit Guide to Linear Algebra https://www.amazon.com/dp/0992001021/ Extended preview: https://minireference.com/static/excerpts/noBSguide2LA_previ...

Both come with a review of high school math topics, which may or may not be useful for you, depending on how well you remember the material. Many of the university-level books will assume you know the high school math concepts super well.

One last thing, I highly recommend you try out SymPy which is a computer algebra system that can do a lot of arithmetic and symbolic math operations for you, e.g. simplify expressions, factor polynomials, solve equations, etc. You can try it out without installing anything here https://live.sympy.org/ and this is a short tutorial that explains the basic commands https://minireference.com/static/tutorials/sympy_tutorial.pd...
