> the average textbook can be condensed to 10% of its volume without any loss of information

It's crazy isn't it? I wrote a math & physics textbook[1] that condenses nearly 2000+ pages of precalculus, mechanics, and calculus, in very few pages. I think I could make it even shorter, but I wanted to include lots of exercises/problems because those are important.
