I agree that examples and asides are useful. What I had in mind is certain chapters in physics or math books that are fully boil down to one equation, but somehow end up stretching the narrative out to fill dozens of pages. Just the other d

Imagine you're the author, and you have to explain derivatives in 100 pages, because your boss asked you to make the book 1000+ pages long. Including definitions, formulas, examples, and problems, you could get to 30 pages. You'd

Yes, textbook pricing is totally out of whack. Also, the need to legitimize the higher sticker prices forces publishers to make books that are bloated, repetitive, and waaay too long. Who has time to read 1000+ pages? The textbook racket an

Is there anything in ECON that's good then? I'm thinking 70% of first-year ECON would be bullshit, but surely some ideas about demand and supply are useful. Are you an economist? Or did you study economics? I'd like to publis

What software did you use for the graph? Looks nice.

The author seems to conflate general math (arithmetic, variables, functions, basic modelling) with specialized math, used for advanced research topics like topology, number theory, etc. Apart from this conflation, the article is very confus

Yeah, that would be amazing. I have a friend of mine who has a PhD in math, but has never learned any physics. Nevertheless, he was able to pick up some pretty advanced physics topics in a few weeks, to everyone's amazement. On the oth

They did say "Look for the source for the code soon ..." so I'm guessing it's coming. You can see some example code in the paper though: http://arxiv.org/abs/1608.03355

The "mechanics" of QM is linear algebra, so you should get a good base in LA before looking into QM. My upcoming book on LA has chapter on QM, specifically "matrix" quantum mechanics, which is the subset of quantum physi

Fabric is a good example of config management as code. While all the app-specific configs are much easier to do this way, it feels like many other tasks (install packages, create users, etc) could be "outsourced" to some sort of s

Could this be used to render React views on the server side? I'd love to use something like https://github.com/markfinger/python-react but without the need to run node.js server on the side. Is there an example I

Yeah, I really like the video speed control for educational videos too. Curious, what speed do you normally use? 2x? more than 2x? Did you know about this app for controlling speed of any HTML5 video element https://chrome.google

Awesome! Would be great if one could use the keys ", ., ,, ;, and maybe p or [ENTER] for newline. Another cool thing would be to prepare a voice recording (3 minutes) and play it on the same speaker to: (A) google voice in speech input

Very cool idea! I think this would work both at the logical level (e.g., the concept of azimutal angle in a xyz-coordinate system) and as a stylesheet level (theta for physcisits, and phi for mathematicians). Such annotations would really h

I'd think it's more the 2nd stage: figuring out what to do, i.e. solving the problem. Once you've settled on the solution, typing it out, testing, and refactoring would be 3rd stage.

For me the most interesting parts are the first (comprehension) and the second (reasoning). The third part "doing of the math" sounds more of a procedural thing, which is important for exams but otherwise very meh. What would be r

The books in the list are pretty advanced. It would be nice to see some sort of "star" rating for each book to indicate which books the authors found best. On a shorter note, here is a four-page introduction to the basics of linea
