The steps are sorted in roughly chronological order. The project might fail at any point, and some steps may be carried in parallel:
  • make OurBigBook Markup good enough, to the point that it allows to create a static version of the website, which is used to prototype certain ideas, and for Ciro to start writing test content.
    Status March 2022: reached a point that it is already highly usable. The following website may continue.
  • create a basic implementation of the website, without advanced features like PageRank sorting and WYSIWYG. This is not much more than a blog with some extra metadata, so it is definitely achievable with constrained resources.
  • find a university teacher would would like to try it out.
    Ciro would like to volunteer to work for free for this teacher and students to help the students learn.
    He would like act like a "super student" who has a lot of free time and motivation.
    Ciro would start by mapping the headers of the lecture notes onto the website, and then slowly adding content as he feels the need to improve certain explanations.
    Finding teachers willing to allow this will be a major roadblock: how to convince teachers to use CC BY-SA.
    If such enlightened teacher is found, it will allow for the initial validation of the website, to decide what kind of tweaking the idea might need, and start uploading quality technical content to the site.
  • once some level of validation as been done, Ciro will start looking for charitable charitable grant opportunities more aggressively
  • if things seem to be working, start adding more advance features: PageRank-like ranking sorting and WYSIWYG editing
    The recommendation algorithms notably is left for a second stage because it needs real world data to be tested. And at the beginning, before Eternal September kicks in, there would be few posts written by well educated university students, so a simple sort by upvote would likely be good enough.
Ciro decided to start with a decent markup language with a decent implementation: OurBigBook Markup. Once that gets reasonable, he will move on to another attempt at the website itself.
The project description was originally at: github.com/cirosantilli/write-free-science-books-to-get-famous-website but being migrated here. The original working project name was "Write free books to get famous website", until Ciro decided to settle for OurBigBook.com and fixed the domain name.
OurBigBook.com / Association with innovative schools Updated +Created
Maybe we should talk to innovative schools, as they might be more open to such use of technology.
OurBigBook.com / Funding Updated +Created
Ciro is looking for:
The initial incentive for the creators is to make them famous and allow them to get more fulfilling jobs more easily, although Ciro also wants to add money transfer mechanisms to it later on.
We can't rely on teachers writing materials, because they simply don't have enough incentive: publication count is all that matters to their careers. The students however, are desperate to prove themselves to the world, and becoming famous for amazing educational content is something that some of them might want to spend their times on, besides grinding for useless grade.

Isomorphism Updated +Created
Something analogous to a group isomorphism, but that preserves whatever properties the given algebraic object has. E.g. for a field, we also have to preserve multiplication in addition to addition.
Other common examples include isomorphisms of vector spaces and field. But since both of those two are much simpler than groups in classification, as they are both determined by number of elements/dimension alone, see:we tend to not talk about isomorphisms so much in those contexts.
OurBigBook.com / Learning management systems Updated +Created
This website basically aims to be a learning management system, allowing in particular a teacher to focus his help on students that he is legally obliged to help due to their job. But it will have the following unusual characteristics in current LMS solutions:
  • public first, to allow reuse across universities, rather than paywalled as is the case for most top universities
  • students can create material just like teachers, both are on equal footing. Students/teachers will see an indicator "this is your teacher"/"this is your student for this/past semester", but that is the only difference between their interfaces.
OurBigBook.com / Manifesto Updated +Created
Education has become an expensive bureaucratic exercise, completely dissociated from reality and usefulness.
It completely rejects what the individual wants to achieve, and instead attempts to mass homogenize and test people through endless hours of boredom.
And the only goals it achieves are testing student's resilience to stress, and facilitating the finding of sexual partners. True learning is completely absent.
Teachers only teach because they have to do it to get paid, not for passion. Their only true incentive is co-authoring papers.
We reject this bullshit.
Education is meant to help us, the students, achieve our goals through passionate learning.
And, we, the students, are individuals, with different goals and capabilities.
The way we protest is to publish the knowledge from University for free, on the Internet, so that anyone can access it.
And we do this is a law-abiding way, without copyright infringement, so that no one can legally take it down.
We come to our courses just for the useless roll calls. But we already know all the subject better than the "teacher" on the very first day.
And we are already more famous than the "teacher" online, and through the Internet have already taught more way way more people than they ever will.
The effect of this is to demoralize the entire school system at all levels, until only one conclusion is possible: implosion.
And from the ashes of the old system, we will build a new one, which does only what matters with absolute efficiency: help the individual students achieve their goals.
A system in which the only reason why university exist will be to allow the most knowledgeable students to access million dollar laboratory equipment, and to pay the most prolific content creators so they can continue content creating.
No more useless courses. No more useless tests. Only passion, usefulness and focus.
