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.

This isn't bad. I'm surprised it's expensive now.

The preview is a "special build" of the book that removes most of the content and leaves only the section formulas and headings --- this way to ensure the internal navigation works, but it's confusing since it looks like chunks are missing. Previously I would cut only selected pages but then the links didn't work. Sorry for the confusion. You can check the preview on amazon for the real page numbers: https://www.amazon.com/dp/0992001005/noBSmathphys

I wrote a book that is exactly what you describe (high school math review for adults), which you can check here: https://www.amazon.com/dp/099200103X/noBSmath (~200 pages = compact review of high school math topics with lots of exercises and practice problems)

The green book is a subset of the longer book that also covers mechanics and calculus https://www.amazon.com/dp/0992001005/noBSmathMechCalc (see preview here https://minireference.com/static/excerpts/noBSguide_v5_previ... )

High school math is very deep, so I will not claim to cover all topics, but I present the most useful parts (equations, algebra, functions and inverses, math modelling), so it would be a good starting point.

Independent and in addition to the above, you can check out this printable tutorial on SymPy that can also be helpful as a review of lots of high school math material: https://minireference.com/static/tutorials/sympy_tutorial.pd...

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...

Wow what an amazing list. It will still take many years to learn all this material, but I think that a dedicated student could follow it and physics up big time! My time estimate for someone with normal intelligence level (i.e. not genius), starting fro scratch and learning part-time, would be 2-3 years. It's totally worth it though for the analytical power that learning physics gives the learner.

Some notes/links below:

> Before you begin studying physics and working through the topics in the sections below, you have to be familiar with some basic mathematics.

That is very true and often a big obstacle for people who have been out of school for some time. Note it's not enough to just be familiar with the concepts—you must achieve fluency with the procedures so you can use them as building blocks for later studies. For example, it's not enough to just read about the quadratic formula (-b ± sqrt(b^2-4ac))/(2a) and use it a few times, spending 5 minutes each time to think about the steps, plugging in the vars, etc.

Because solving quadratic equations is used so much in math and physics, you have to package that procedure as a reusable routine that you don't think about anymore and you can apply almost without thinking, in under 30 seconds. This "fluency with the basics" will ensure you're not slowed down when you reach the more advanced topics where solving quadratic equations is used.... and there is only one way to build fluency...

> Regardless of your learning style, you'll still need to solve the physics problems in each textbook. Solving problems is the only way to really understand how the laws of physics work. There's no way around it.

This. A thousand times this. I wish someone told me that when I was studying. It may not be fun to get stuck, go down the wrong path, doubt your abilities and feel stupid along the way, but that's what growth looks like. If every time you read a solution to a problem provided by someone else you gain one "knowledge unit," then finding the solution on your own is > 10 knowledge units. Forget 10x engineer, be a 10x learner—solve some problems!

> 1. Introduction to Mechanics [...] the basics of motion in a straight line, motion in two dimensions, motion in three dimensions, Newton's Laws, work, kinetic energy, potential energy, the conservation of energy, momentum, collisions, rotation and rotational motion, gravitation, and periodic motion. > You'll need to learn calculus while working through University Physics. >

Shameless plug, I wrote a book called No Bullshit Guide to Math and Physics that covers these exact topics. It would be a great starting point for someone who wants to review high school math and learn mechanics and calculus in an integrated manner. Here are some links if anyone wants to check it out:

"Pay the authors" is a really good strategy to incentivize the production of quality content. Get rid of the publishers and just have a short supply chain: author --print_on_demand--> readers. With a price tag in the 20-50 range, a prof could make a living from this book, even if the book isn't popular. When using print-on-demand and cutting out all the middlemen, the margins are very good (50% of list price vs 5% if going with mainstream publisher).

The useful part of a publisher is developmental editing (product) and copy editing (Q/A), so there is an opportunity for "lightweight" publishing companies that help expert authors produce the book—like self publishing, but you don't have to do the boring parts. I'm working in that space. We have two textbooks out: https://www.amazon.com/dp/0992001005/noBSmathphys and https://www.amazon.com/dp/0992001021/noBSLA

> staff heard that some students were skipping meals in order to afford textbooks

!!!

If you're a freshman in college, please check out my book: https://www.amazon.com/dp/0992001005/noBSguide It's super affordable and it will get you through MECHANICS and CALCULUS without too much suffering.

Shameless plug, I wrote a book that you can read and learn the first-year science essentials: calculus and mechanics, for the price of a 24 case of beer: https://www.amazon.com/dp/0992001005/noBSguide

You won't get a degree or anything, but the knowledge will last with you longer than the case of beer ;)

I have quite a few adult readers using my book to refresh and re-learn basic calculus and mechanics. You might consider checking it out[1]. It's not free, but very affordable.

From the fist paper: If you want to learn more university-level math and physics, I invite you to check out my book, the No bullshit guide to math and physics

I just wanted to pop in and say this book has been excellent. These papers are brief and therefore a bit cryptic, but the book is eminently readable. https://www.amazon.com/No-bullshit-guide-math-physics/dp/099...
