This term was invented by Ciro Santilli, and similar ideas certainly already exists with different names by other people. As the name suggests, it basically involves combining free education and gifted education, but with other more specific aspects crammed in that would make a precise name too long to read, as descried below.
Government must create selective, K-12 and university-level teaching institutions that are completely free.
As mentioned at pick few good bets and invest enough on bets, these do not need to be given to all students: what we have to do is to ensure that the top N-percent of the best students will get in, and that none of them will pay. Where N is as large as the budget society decides to put into this project, the larger the better. Therefore, perhaps "gifted education" is not the ideal name for this idea, as it generally implies very small N (1%?), while this project hopes for larger N, maybe 10%. But a minimal level of quality must be attained, it is pointless to dissolve the resources too much, if we only have enough for 1%, then so be it, start with 1%.
These institutions must start from the very first school year, and go all the way up through K-12 to the end of university. It is useless to start at university-level only otherwise only the rich students will have a chance of getting in, like Ciro Santilli saw in Brazil at the Polytechnic School of the University of São Paulo in the late 2000's: one day all students were gathered in the amphitheater, and they asked the students who had only gone through free government K-12 schools to raise their hands. Those were notably worse than the corresponding private schools, and the situation is inverted in university, where the best schools are the government ones. Out of about 500 people, at most 10 raised their hands!
These institutions should not have affirmative action entry quotas, including most importantly at the university level. Both rich and poor should be able to apply. Passing the selection criteria is all that matters. We just must ensure that the schools are widely advertised amongst disadvantaged communities, so that they will at least get their children to try to apply from an early age. This way, even if the rich always have an advantage due to better overall conditions, the poor are so much more numerous that the majority of students accepted will still be poor.
The school should follow the basic principles of how to teach, notably:
- students must have a flexible choice of what to learn. There will be no classes, all learning will happen either OurBigBook.com or on 1-to-1 meeting with tutors, or in discussions with fellow students.The term "gifted education" might suggest elitism, but Ciro Santilli strongly believes that different people have different skills, and that if everyone could focus on whatever it is that they want to do in life, be it engineering or the arts, rather than just pass a bunch of useless exam, then having the 10% "best" of each interest group would already cover a huge percentage of the population.
- Through it, students will be helped to directly achieve their greater life goals.There will be no teachers: each student will be assigned senior advisors, and together they will come with an individualized research proposal or business plan.There will be no useless mandatory institutional exams. Exams only need to be taken if a given advisor requires it to filter candidate students. But if you manage to impress them through other means, they can just accept you without the exam.A fundamental part of this is to fill the the missing link between basic and advanced. We want to help students to reach the state of the art of their field of interest as fast as possile.
- group students by interest, not by age
These schools must pay mentors as much as the average good non-free schools so you actually get comparably good teachers. Mentor selection would also be highly competitive, just as that of the students.
Once admitted, students will have guaranteed access to the school resources for a few years. This way, they won't need to worry about passing useless exams every three months.
All that matters is that they are progressing in their development plan. Rather than exams, students will do regular progress report sessions with their advisors, and will get periodic reviews from other advisors with similar interests.
Such projects could be funded by much needed wealth tax or other measures to tax the rich, which the people should claim through Referendum, that would be come more common with the adoption of electronic voting. Because the politicians are simply not being able to do it.
On a plate by Toby Morris (2015)
Source. Ciro Santilli is against affirmative action university entry quotas that reserve spaces e.g. for students from discriminated races or poor families. Instead, he believes that affirmative action should take place on earlier stages of education as described at: free gifted education.
Notably, Brazil has implemented a very heavy university entry quota system after Ciro had left university there: www.bbc.co.uk/news/business-23862676
This is of course easy for a white male from a privileged background to say, and infinite debate has already been had on this matter, but here goes again.
First, in defense to the personal attack, Ciro raises the fact that he has dedicated large chunks (all?) of his life to open source software and knowledge in general, which Ciro believes is the only way to actually make the world fairer to poor countries. His money (time) is where his mouth is.
One good argument in favor of the Brazilian quota system, is that the kids who enter university because of quotas do just as well as those who don't.
Ciro has actually believes that this is possible, and offers the following possible explanation: most of pre-university knowledge is useless, and university selection system is crap, and Ciro wants to destroy it with a system in which anyone can learn university stuff from home.
Both the top end of the quota and non-quota kids are basically equally capable of doing useful stuff therefore.
And possibly more importantly than knowledge, Ciro saw many of his colleagues (basically all of which were from relatively privileged backgrounds) "do badly" in university, because of lack of motivation, because they had chosen a course only to find that they were not interested in it because the existing high school educational system is crap and does not help them find what they love and because it costs you several years of your life to change your choice in most universities (long live École Polytechnique).
Maybe the fact that poor kids know that they are fucked if they fail, and so they have to succeed at any cost, might also help with motivation. Which is a terrible terrible thing, because only those who have to leeway to take risks end up taking them and making the the next big thing.
Ciro believes instead that only once kids have learnt university level stuff in their area of interest for free on the Internet should they go through selection based on that specific and much more concentrated useful knowledge.
And this competition must only be used to distribute resources which you can't learn from fucking computers:
- laboratories. Actually, one of Ciro's most important advices to kids nowadays is: when in doubt, choose the course that has the most experimental work
- one to one mentorship on advanced master thesis/PhD level projects
Once this point knowledge is reached however, it starts to become unclear if a single "everyone takes the same test to avoid discrimination" test is feasible anymore, and we start entering the much more relevant (and potentially discriminatory) "I am a teacher trying to advance the state of the art, and I need a person mildly skilled in the art to do some slave labor for me", which is PhDs selection work.
If quota are in place, what will happen is that parents of the rich kids will start investing less in education, and possibly just put their kids in high schools, and do home schooling instead. This would therefore reduce the total investments the country makes in education!
Outside of the obvious technical evolution proposed, Ciro is a huge proponent of free gifted education. Or closely related, creating scholarships that focus on poor students. The entry requirements should be the same, but once you qualify, everyone should have enough money to lead a decent life during their studies.
Then let those kids pass exactly the same university entry exams, and watch them crush the average privileged kids.
This advice is similar to what is mentioned at: what poor countries have to do to get richer. When you don't have money to do everything, you must select a few good bets and focus on them. You can't pay a lot to every public school teacher, so you must select a few select places that need it the most. As those smart bets pay off, you start to have more and more money to expand the system further.
Inside Westside Barbell by Vice News (2018)
Source. One sentence of this nice documentary about the notorious Westside Barbell gym where the openly pro-performance-enhancing-drug powerlifting legend leader and cult-leader-like personality Louis Simmons teaches just stuck to Ciro Santilli's mind. His top tenant and manager Tom Barry talks about Louis:Ciro admires this level of focus, directness and meritocracy. Just don't take drugs, children. Louis' creation of a cult-like training atmosphere is another interesting aspect, see also: Section "Group students by interest, not by age".
The man [Louis] lives in his own world, and he just rejects everything outside of it, it doesn't matter. Like: "what's your name"? He doesn't care. If you lift numbers, he cares about that, that's more important.
Taxes pay for the physical car roads, so why shouldn't they also pay for the "online roads" of today?
The following services are obvious picks because they are so simple:
Other less simple ones that might also be feasible:
- geographic information system. Notable anti-example: United Kingdom's Ordnance Survey's apparently non-free-data
- App stores
All of them should have strong privacy enabled by default: end-to-end encryption, logless, etc. Governments are not going to like this part.
And then if you ever forget a password or lose a multi-factor authentication token, you can just go to an ID center with your ID to recover it.
Ciro Santilli is a big believer that there is value in tutorials written by beginners, because beginners are more likely to explain things in a way that other beginners can understand.
Even though they make more mistakes, this more approachable point of view can be very valuable.
And mistakes/omissions can be corrected on comments by people with more knowledge, so that the writer also ends up learning something new.
By other people:
- jakobschwichtenberg.com/about/ from Jakob Schwichtenberg mentions quotes C. S. Lewis book "Reflections on the Psalms"[ref]:
It often happens that two schoolboys can solve difficulties in their work for one another better than the master can. [...] The fellow-pupil can help more than the master because he knows less. The difficulty we want him to explain is one he has recently met. The expert met it so long ago he has forgotten. He sees the whole subject, by now, in a different light that he cannot conceive what is really troubling the pupil; he sees a dozen other difficulties which ought to be troubling him but aren't.

And of course:
Ciro Santilli's energy throughout the day varies as follows:
- morning: highest
- 11AM: peak exercise performance
- after lunch: brain death. Possibly due to Ciro's partial Spanish descent?
- late afternoon and evening: can do some stuff
Ciro has low tolerance to sleep deprivation which makes him very irritable, and low ability to sleep if there is any light. It must have to do with those damned ganglion cell photoreceptors. On the other hand, Ciro Santilli's wife can sleep without any problems with some morning light! It is definitely genetic. Ciro conjectures that people from very Northern parts of the world must have a gene that allows them to sleep even if there is some light, while more equatorial people don't. Maybe: pubmed.ncbi.nlm.nih.gov/33049062/
Ciro has mild olfactory synesthesia for star anise (八角, bajiao), which is widely used in Chinese cuisine and makes Ciro think uncontrollably of the color blue. Ciro does not have any other known synesthesias. He is also prone to nerd sniping form time to time.
Ciro is a reptilian-like being with cold hands and feet and low blood pressure. For this reason he believes that he will die of cancer or some respiratory problem. If the Chinese government doesn't get him first that is. This also partly explains why Ciro is not a big fan of swimming.
Besides Chinese food, Ciro really likes eating fruits and roasted nuts, maybe partly because he was born in Brazil, and partly because of monkey nature, see his Chinese name. At home he is known as "水果大王" (the big king of the fruits). Ciro is also a sucker for yoghurt (natural without added sugars and full fat, fat-tree yoghurt is terrible, often eaten with fruits). Ciro's "favorite drink" could be tonic water with freshly squeezed lemon. Tied with fresh fruit juices. Chocolate-wise, although not a huge fanatic, a Lindt dark chocolate with whole hazelnut pieces bar will do the job.
Ciro does not like receiving or giving gifts on expected social situations like birthdays or Christmas. Ciro believes that every day is equally precious, and can be a day to give, be it through awesome open source software contributions, or if you find something that your friend will like
Ciro has some respiratory allergies. When he was around 5, he had relatively serious asthma crisis which scared his parents to death. Throughout his life, he appears to be allergic at an intermediate level to: mold or dust mites (or whatever it is that old books/pillows have), cats (itching on touch), hay fever (in May in the UK, likely grass pollen). But even outside of hayfever season, Ciro's nose is constantly either running in the cold, or often partially blocked while sleeping throughout the year. Ciro believes however that this also gives him higher resistance to viral infections, since it has been many many years since he had a cold/flu, and when everyone in the office is going down with it, he's just fine. Ciro wonders if his active immune system will actually kill off cancers early, which he ranks as his most likely causes of death, along with respiratory and gastro-intestinal problems. Ciro has low blood pressure and cannot get fat, so cardio vascular problems seem much less likely.
Ciro is generally democrat due to his high compassion level. He believes that politics is highly genetically determined, and that just like you enter a room full of people and immediately like some and dislike others, the same goes for politics. People just vote for whoever they want to see more of because their way of speaking makes them feel good. There is not rationality involved in it at all.
Ciro self diagnoses a slight graphomania in the early 2020's. This is largely what led him to create OurBigBook.com, and contribute to Stack Overflow. Literature Nobel Prize laureate Naguib Mahfouz also suffers from the condition however, so maybe good can also come out of it:
When Ciro was quite young, maybe around 7-10, when he got very angry or sad for some stupid reason (bullying perhaps? Ciro forgot), he would have a psychosomatic manifestation: his spine would become visibly curved sideways (scoliosis). While writing this paragraph, Ciro Googled it, and found e.g. medium.com/@michaelrosen_94192/the-root-cause-of-scoliosis-5c461002b634 that describes:so it is a somewhat well known thing! Incredible. Can you imagine the level of the passions that lead to such physical deformations? But of course, it was all for nothing.
The Root Cause of Idiopathic Scoliosis
David Hall is a chemist known for his contributions to the field of organic chemistry, particularly in areas related to synthesis and reaction mechanisms. His work often involves the development of new synthetic methodologies and understanding chemical reactivity.
Ciro Santilli has an undiagnozed condition where his upper legs and lower torso often start to itch when he runs, to the point of being extremely annoying and removing all pleasure form the activity.
If some doctor knows why this could be, please tell him!!!
The problem is a bit hard to reproduce however, and Ciro hasn't been able to determine which exact condition triggers it: temperature, nutrition, something else?
Ciro believes that this is not chiefly due to transpiration, but rather to the impact motion that running does on the muscles, as he has felt something similar on his arms some times while cycling in very rough terrain, which made his arms shake in a similar fashion. or for example if he has a water bottle on a tightly tied backpack that rubs his back, then the back itches at that point.
Also, running on a threadmill is not a problem at all. Ciro believes that this is because the threadmill is better amortized, and therefore does not cause the same mechanical stress required to create the itching as running on pavement.
Interestingly, Ciro didn't feel that at all when he played soccer enthusiastically as a child, and he was one of the fastest runners of the group for sure at that time. So he's not sure if it started when he got older, or if it is just because the difference in workloads between soccer and running.

The first one came to me as if coming from the flower shop
Brought a stuffed toy, brought an amethyst pin
He told me about his journey and the perks he had
He showed me his watch and called me 'queen'
He found me so undefended that he touched my heart
But he denied me nothing, so, frightened, I said 'no'The second came to me as if coming back from the bar
Brought a bottle of brandy too bitter to swallow
He asked me about my past and sniffed my food
He searched through my drawer and called me 'the lost one'
He found me so undefended that he scratched my heart
But he gave me nothing, so, frightened, I said 'no'

Ciro Santilli with his soon-to-be Ciro Santilli's mother-in-law during his wedding in 2017
. Count: 0.
Firstly, in 2012, while he was at École Polytechnique, Ciro Santilli was introduced to LaTeX (thank God for French mathematical obsession), and his mind was blown:he though. Why isn't everyone doing that!
One particular event stood out: Ciro made a small change to his teacher's course material, who blessed be him (dude's a legend, Ciro just noticed he has some Chinese publications with another French dude, e.g. www.amazon.co.uk/高效算法-应试与提高必修128例-克里斯托弗-Christoph-Durr/dp/B078SJQPVK "High-efficiency algorithm competitions 128 examples", did he write it the Chinese himself?? Must be of course to complement the notoriously low French professor salaries), made it available, and then Ciro gave him back the .tex file. Ciro was just a bit worried about how the teacher would be able to tell what he had changed in the file to validate the change. The teacher just said of course, "no problem, I'll just use
diff". Ciro had never heard of diff. Let alone Git of course, though yes, this was a bit early in Git's history version control systems had been around since forever of course. This was 2011 or 2012, about 4 or 5 years into a superior education curricula with various courses involving computers, some requiring quite a lot of "fill these empty functions" style programming. Education is a joke. Anyways, this was a prelude to exactly what Ciro wanted to do in OurBigBook.com. This might have been the one actually: webia.lip6.fr/~durrc/Iut/Notes580.pdfNot long afterwards, Ciro started playing with Linux. Until then, Ciro had had some contacts with the mysterious operating system at university, and was a bit puzzled what the point of it was! He clearly remembers:University should be forced to use only open source software and hardware in undergrad teaching courses by law BTW.
- at the University of São Paulo that they had some "UNIX" computers in some classes, and at the library
- at École Polytechnique, he took a course about mathematical analysis and there was a "lab" where students were supposed to use FreeFem, great initiative BTW. And Ciro distinctly remembers being paried with a nice Chilian colleague, and the guy was alreay super at ease with the shell: "cd", "ls", etc. WTF was all that!
Then came an Ubuntu live disk on his own machine, and finally a measly 40GB dual book partition in a Microsoft Windows machine on a laptop. At first, it took a lot of time to learn all the crazy new terminal stuff! Yes, at this point, Ubuntu was already usable enough without the terminal, an accomplishment actually. But as a programmer, Ciro felt obliged to learn. Many hours were spent reading man pages at the library. But it all just felt so right, and sometimes powerful... true wizardry.
And ten years later, Ciro was seriously considering buying a computer without Windows pre-installed. He had not used Windows a single tie on a personal machine even once in those ten years!
Finally, to finish things off Ciro found two websites that changed his life forever, and made be believe that there was an alternative: Stack Overflow and GitHub.
These are websites that offer somewhat overlapping services, many of which served inspirations, and why we think something different is needed to achieve our goals.
Notably, OurBigBook is the result of Ciro Santilli's experiences with:OurBigBook could be seen as a cross between those three websites.
- Wikipedia
- GitHub
- Stack Exchange (or as non techies might point out, Urban Dictionary, or Quora before it was such an incomprehensible shitshow)
Quick mentions:
- handwiki.org/wiki/HandWiki:About: technically the same as Wikipedia, but with more aligned moderation policies
- ecotext.co/ similar goals. Their website seems quite broken now though as of 2021, can't see text properly. Crunchbase entry: www.crunchbase.com/organization/ecotext says they are from Durham, New Hampshire, United States. Cannot see how to publish, curated material only?

- fiveable.me/ bad: separates students and teachers, as a student I don't see where to create my content. Good: focus on teaching university level stuff to people outside of university via Advanced Placement. Bad: Lots of video content. Bad: Can't see the issue tracker attached to each page.
- LessWrong: their website system does have some similar feature sets to what we want. Reputation, Q&A sections, links between articles most likely, sort by upvote everywhere.
- crowdpub.org collaborative writing website, somehow goes to paragraph level, TODO how they reconcile different authors? Closed beta as of writing, so hard to be sure. From quick presentation on beta website, appears to attempt to share revenue to authors proportionally to the size of their contribution. Some blockchain-based reputation. Meh.
- TODO migrate all from: github.com/booktree/booktree/blob/master/alternatives.md
- studynotes.ie/. Admin approval on everything. No ToC. Fixed tag list for university entry exams topics.
- mindstone.com: there appears to be no sharing focus? File upload basesd? Not sure.
- EverybodyWiki

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
