Check out: OurBigBook.com, the best way to publish your scientific knowledge. It's an open source note taking system that can publish from lightweight markup files in your computer both to a multi-user mind melding dynamic website, or as a static website. It's like Wikipedia + GitHub + Stack Overflow + Obsidian mashed up. Source code: github.com/ourbigbook/ourbigbook.
Sponsor me to work on this project: 100k USD = I quit me job and work on it one year full time. Status: ~144k / 200k USD reached: 1st year locked-in, 2nd year stretch goal open at 200k USD. 1M USD = I retire and do it forever. How to donate: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
I reached 100k USD after a 1000 Monero donation, so I quit my job for 1 year starting 1st June 2024 to solve as many STEM courses as I can from a world leading university to try and kickstart The Higher Education Revolution. If I reach 200k USD, then I'll do it for two years instead. A second year greatly improve chances of success: year one I solve a bunch of courses, year two I come guns blazing with the content and expand further.
Mission: to live in a world where you can learn university-level mathematics, physics, chemistry, biology and engineering from perfect free open source books that anyone can write to get famous. More rationale: Section "OurBigBook.com"
Explaining things is my superpower, e.g. I was top user #39 on Stack Overflow in 2023[ref][ref] and I have a few 1k+ star educational GitHub repositories[ref][ref][ref][ref]. Now I want to bring that level of awesomeness to masters level Mathematics and Physics. But I can't do it alone! So I created OurBigBook.com to allow everyone to work together towards the perfect book of everything.
My life's goal is to bring hardcore university-level STEM open educational content to all ages. Sponsor me at github.com/sponsors/cirosantilli starting from 1$/month so I can work full time on it. Further information: Section "Sponsor Ciro Santilli's work on OurBigBook.com". Achieving what I call "free gifted education" is my Nirvana.

Besides that, I'm also a freedom of speech slacktivist and recreational cyclist. I like Chinese traditional music and classic Brazilian pop. Opinions are my own, but they could be yours too. Tax the rich.
Let's create an educational system with:
- no distinction between university and high school, students just go as fast as they can to what they really want without stupid university entry exams
- fully open source learning material
- on-demand examinations that anyone can easily take without prerequisites
- granular entry selection only for space in specific laboratories or participation in specific novel research projects
I offer:
- online private tutoring for:
- any STEM university course
- passionate younger STEM students (any age) who want to learn university level material and beyond. Can your kid be the next Fields Medalist or Nobel Prize winner? I'm here to help, especially if you are filthy rich! I focus moving students forward as fast as they want on and on producing useful novel tutorials and results
Let your child be my Emile, and me be their Adolfo Amidei, and let's see how far they can go! I will help take your child:and achieve their ambitious STEM goals!- into the best universities
- into the best PhD programs
- educational consulting for institutions looking to improve their STEM courses
- do you know that course or teacher that consistently gets bad reviews every year? I'll work with the teacher to turn the problem around!
- are you looking to create a consistent open educational resources offering to increase your institutions internationally visibility? I can help with that too.
My approach is to:For minors, parents are welcome to join video calls, and all interactions with the student will be recorded and made available to parents.
- propose interesting research projects. The starting point is always deciding the end goal: Section "Backward design"
- learn what is needed to do the project together with the student(s)
- publish any novel results or tutorials/tools produced freely licensed online, and encourage the student to do the same (Section "Let students learn by teaching", digital garden)
I have a proven track of explaining complex concepts in an interesting and useful way. I work for the learner. Teaching statement at: Section "How to teach". Pricing to be discussed. Contact details at: Section "How to contact Ciro Santilli".
I am particularly excited about pointing people to the potential next big things, my top picks these days are:I am also generally interested in:
- 20th century physics, notably AMO and condensed matter
- the history of science, and in particular trying to look at seminal papers of a field
Ciro Santilli's amazing Stack Overflow profile

Artist unknown, uploaded December 2014. Part of Section "Cool data embedded in the Bitcoin blockchain" where Ciro Santilli maintains a curated list of such interesting inscriptions.
This was a small project done by Ciro for artistic purposes that received some attention due to the incredible hype surrounding cryptocurrencies at the time. Ciro Santilli's views on cryptocurrencies are summarized at: Section "Are cryptocurrencies useful?".
YellowRobot.jpgJPG image fully embedded in the Bitcoin blockchain depicting some kind of cut material art depicting a yellow robot, inscribed on January 29, 2017.
Ciro Santilli found this image and others during his research for Section "Cool data embedded in the Bitcoin blockchain" by searching for image fingerprints on every transaction payload of the blockchain with a script.
The image was uploaded by EMBII, co-creator of the AtomSea & EMBII upload mechanism, which was responsible for a large part of the image inscriptions in the Bitcoin blockchain.
The associated message reads:This is one of Ciro Santilli's favorite AtomSea & EMBII uploads, as it perfectly encapsules the "medium as an art form" approach to blockchain art, where even non-novel works can be recontextualized into something interesting, here depicting an opposition between the ephemeral and the immutable.
Chiharu [EMBII's Japanese wife] and I found this little yellow robot while exploring Chicago. It will be covered by tar or eventually removed but this tribute will remain. N 41.880778 E -87.629210
At twitter.com/EMBII4U/status/1615389973343268871 EMBII announced that he would be giving off shares of that image on Sup!?, a Bitcoin-backed NFT system he was; making. In December 2023, he gave some shares of the robot to Ciro Santilli.

. This website was used as one of the CIA 2010 covert communication websites, a covert system the CIA used to communicate with its assets. More details at: Section "CIA 2010 covert communication websites".
Ciro Santilli had some naughty OSINT fun finding some of the websites of this defunct network in 2023 after he heard about the 2022 Reuters report on the matter, which for the first time gave away 7 concrete websites out of a claimed 885 total found. As of November 2023, Ciro had found about 350 of them.
2010 Wayback Machine archive of noticiasmusica.net
. This is another website that was used as one of the CIA 2010 covert communication websites. This website is written in Brazilian Portuguese, and therefore suggests that the CIA had assets in Brazil at the time, and thus was spying on a "fellow democracy".
Although Snowden's revelations made it extremely obvious to the world that the USA spies upon everyone outside of the Five Eyes, including fellow democracies, it is rare to have such a direct a concrete proof of it visible live right on the Wayback Machine. Other targeted democracies include France, Germany, Italy and Spain. More details at: USA spying on its own allies.

He put it there after working a bit on Section "How to use an Oxford Nanopore MinION to extract DNA from river water and determine which bacteria live in it" :-) And he would love to document more experiments like that one Section "Videos of all key physics experiments", but opportunities are extremely rare.
A quick 2D continuous AI game prototype for reinforcement learning written in Matter.js, you can view it on a separate page at cirosantilli.com/_raw/js/matterjs/examples.html#top-down-asdw-fixed-viewport. This is a for-fun-only prototype for Ciro's 2D reinforcement learning games, C++ or maybe Python (for the deep learning ecosystem) seems inevitable for a serious version of such a project. But it is cute how much you can do with a few lines of Matter.js!

This is the project with the closest philosophy to OurBigBook that Ciro Santilli has ever found. It just tends to be even more idealistic than, OurBigBook in general, which is insane!
Source code: sr.ht/~jonsterling/forester. Not on GitHub, too much idealism for that.
"Docs" at: www.jonmsterling.com/foreign-forester-jms-005P.xml Sample repo at: github.com/jonsterling/forest but all parts of interest are in submodules on the authors private Git server.
Example:
- sample source file: git.sr.ht/~jonsterling/public-trees/tree/2356f52303c588fadc2136ffaa168e9e5fbe346c/item/jms-005P.tree

They have
\Include like OurBigBook, nice: www.jonmsterling.com/jms-007L.xml, but OMG that name \transclude{xxx-NNNN}!! It seems to be possible to have human readable IDs too if you want: www.jonmsterling.com/foreign-forester-armaëlguéneau.xml is under trees/public/roladex/armaëlguéneau.tree.Headers have open/close:OurBigBook considered this, but went with
\subtree[jms-00YG]{}parent= instead finally to avoid huge lists of close parenthesis at the end of deep nodes.One really cool thing is that the headers render internal links as clickable, which brings it all closer to the "knowledge base as a formal ontology" approach.
Does not encourage human readable IDs, uses stuff like
jms-00YG.The markup has relatively few insane constructs, notably you need explicit open paragraphs everywhere The markup is documented at: www.jonmsterling.com/foreign-forester-jms-007N.xml
\p{}?! OMG, too idealistic, not enough pragmatism. There are however a few insane constructs:[](): markdown like links[[bluecat]]: wikilinks (but to raw IDs only, you can't seem to be able to do[[blue cat]]#{}and##{}for inline and block maths, though that might just be a sane construct with an insane name
Jon has some very good theory of personal knowledge base, rationalizing several points that Ciro Santilli had in his mind but hadn't fully put into words, which is quite cool.
OCaml dependency is not so bad, but it relies on actually LaTeX for maths, which is bad. Maybe using JavaScript for OurBigBook wasn't such a bad choice after all, KaTeX just works.
Viewing the generated output HTML directly requires
security.fileuri.strict_origin_policy which is sad, but using a local server solves it. So it appears to actually pull pieces together with JavaScript? Also output files have .xml extension, the idealism! They are reconsidering that though: www.jonmsterling.com/foreign-forester-jms-005P.xml#tree-8720.The Ctrl+K article dropdown search navigation is quite cool.
\rel and \meta allows for arbitrary ontologies between nodes as semantic triples. But they suffer from one fatal flaw: the relations are headers in themselves. We often want to explain why a relation is true, give intuition to it, and refer to it from other nodes. This is obviously how the brain works: relations are nodes just like objects.They do appear to be putting full trees on every toplevel regardless how deep and with JavaScript turned off e.g.:
which is cool but will take lots of storage. In OurBigBook Ciro Santilli only does that on OurBigBook Web where each page can be dynamically generated.
The website is the reference instance of OurBigBook Web, which is part of the OurBigBook Project, the other main part of the project are software that users can run locally to publish their content such as the OurBigBook CLI.
