I’m happy to announce the No bullshit guide to linear algebra (student edition) is ready: gum.co/noBSLA. The core chapters—the stuff that shows up on exams are done. If you have a linear exam coming up, we’ve got what you need.

For the price of a case of beer, you could have an understanding of linear algebra.

Now if you’re a cheapo like me, you’ll say “why the hell do I need to give you money, when there are free books out there?” I understand you. Perhaps you’d like this free tutorial: LA. See also MECH. By reading these short tutorials, I hope to convince you that synthesis of information (i.e. the order of the concepts and choosing an appropriate level of detail) is possible and desirable. Synthesis helps with understanding. If a subject can be summarized in just a few pages, then a full textbook on the subject shouldn’t be bigger than a couple hundred pages, including prerequisites. I call this “information distillation.”

The 1000pp+ textbooks are a scam. Don’t be duped. Get the No bullshit guide to linear algebra. It’s 1/10th the price, 1/2 the size, and 3 times better than a mainstream textbook.  In the news: [HN1], [HN2]. The price is 50% OFF until April 1st.


BTW, this is the second book in the “No bullshit” series. The No bullshit guide to math and physics is the first. It covers high school math, mechanics, differential calculus,  and integral calculus in 383 pages. You should definitely check it if you’re taking one of these classes.
