Nice. Good to see actual hard science books popularized and available for free.

The textbook industry is a criminal cartel shafting both the students/knowledge seekers and authors/professors. Hence i really appreciate the way you have made the pdf available both for free and for a nominal price; so thank you.

We need more hard science (Physics/Chemistry/Biology/etc.) content (books/articles/videos/etc.) on HN. For example, the interdisciplinary field of "Materials Science" (https://en.wikipedia.org/wiki/Materials_science) is one the most practical and important for our modern world and yet there is hardly any discussions/popularization about it.

I used to think that way about the publishing industry too, but I now think that this description is not deserved. Just observing it from an operational perspective: a laptop to type, software to edit, book printers that will talk to you, payment rails, and even access to world-class distribution: it’s all available to us now. On the other side of the market, students and teachers are not locked in either. Barriers to entry are nonexistent. For context, see the links I posted in my other comments on this page. It’s all in our hands!

Right; there are lots more options available to authors today.

However, hard copy textbooks are still the dominant form in much of the developing world. We "technically literate" people often forget that we live in a bubble of our own making. A large percentage of students in the developing world simply do not have the means nor access to technology the way we do. They are dependent on low-cost printed textbooks to study and avail opportunities to get ahead in life.

The Textbook publishing industry is a cartel often pricing their offerings out-of-reach of economically disadvantaged students. Education and its prerequisite, access to textbooks, should be treated the same way we make available generic drugs in the pharmaceutical industry i.e. cheap/low-cost, decent quality offerings available to everybody. The prices of many of the textbooks is often eye-watering and that is why you have many low-cost textbook publishers in the developing world.

My main frustration is that most(all?) authors/professors are quite willing to forego any profits if it means they can get their textbooks into the hands of the students who need them. It is the publishing industry acting as the middleman and focused solely on profits which is ruining everything for everybody.
