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. For 200k USD I will quit my job or not get a new job and work on OurBigBook full time for a second year to try and kickstart The Higher Education Revolution. Status: ~44k / 200k USD. At 2M USD I retire/tenure and work on open STEM forever. How to donate: Section "Sponsor Ciro Santilli's work on OurBigBook.com".
I first quit my job 1st June 2024 to work on the project for 1 year after I reached my initial 100k goal mostly via a 1000 Monero donation. For a second follow up year, I increased my requirement to 200k USD to give me more peace of mind. So the total donation so far is 144k, and if I reach a total of 300k USD, then I'll work on the project for a second year. A second year greatly improve chances of success: year one I improved my tech, year two I come guns blazing to solve courses 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.

ASCII art of a Force of Will Magic: The Gathering card inscribed in the Bitcoin blockchain
.
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.jpg
. Source.
JPG 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:
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
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.
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.

Intro/docs: www.jonmsterling.com/jms-005P.xml. It is very hard to find information in that system however, largely because they don't seem to have a proper recursive cross file table of contents.
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!
"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.
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:
\subtree[jms-00YG]{}
OurBigBook considered this, but went with 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 \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
The markup is documented at: www.jonmsterling.com/foreign-forester-jms-007N.xml
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.

Holy fuck what a eye watering amount, $800k over 5 years as of 2025, this is exactly what Ciro Santilli would need to push forward OurBigBook! He also fits the requirements quite well, as a "creative person". For Americans or US residents only though, sad. Outdated requirement given the Internet age.

A list of reviews of such systems is maintained at:
This is the class of existing software the perhaps comes the closest to OurBigBook, in particular systems such as:
While we believe that OurBigBook can hold its own against most of them as a personal knowledge base, there is one feature which we believe truly distinguishes OurBigBook from all others in a big way: trustless mind meld with the OurBigBook topic feature, which no other system seems to have.
Many such systems are also no publishing focused enough, and are more focused only in maintaining people's private knowledge bases. Some of them don't even have publishing at all, or its complicated. While publishing is optional in OurBigBook, it is a crucial feature and extremely well supported.

This is an interesting initiative which has some similarities to Ciro Santilli's OurBigBook project.
The fatal flaw of the initiative in Ciro Santilli's opinion is the lack of user-generated content. We will never get there without UGC and algorithms, never.
Also as of 2021, it mostly useless business courses: learn.saylor.org unfortunately.
But it has several redeeming factors which Ciro Santilli aproves of:
The founder Michael J. Saylor looks a bit crooked, Rich people who create charitable prizes are often crooked comes to mind. But maybe he's just weird.

Ciro Santilli is actively looking for donations and contracts so he can continue to work full time on OurBigBook.com sustainably, and develop free hardcore university-level STEM education for all ages!
For 200k USD I will quit my job or not get a new job and work on OurBigBook full time for a second year to try and kickstart The Higher Education Revolution. Status: ~44k / 200k USD.

Total donations to date ~144k USD. Donation breakdown:
More details: Section "Accounting method"
How to give:
And if you have a different preferred payment mechanism not listed above, please contact Ciro, and he will set it up.
Ciro's current ambitions require him to remain in developed countries, because Ciro wants to document advanced science and technology by liaising with top universities, and there is not nearly as much high technology in poor countries. Remaining in developed countries is also a required due to family reasons.
Note to potential anonymous crypto donors: anonymous donations incur a regulatory risk. I cash out most of such donations and announce it very clearly to the government and banks. For example, at one point Barclays even froze my UK account. But things seem manageable for now. On one hand, such donations serve as a fun test of the financial system. But on the other, if all banks reject my money or if the government decides to take it, I will write off the anonymous donation at zero.
If you would like public acknowledgement for your support, Ciro will very gladly give it, just let Ciro know how you'd prefer it. Due to Ciro Santilli's campaign for freedom of speech in China, many supporters have chosen to be anonymous, and that is totally fine, not everyone is interested in politics, or has a situation where going public is acceptable, so we don't have a standard setup yet, let's build it together. A acknowledgement section at the bottom of this page would be a minimum, but I for larger donations we could add a your advertisement in a locations such as:
100k USD/year is a semi arbitrary amount that sounds nice. My last day job total compensation as of 2024 was about 150k USD/year.

Maybe if he ever gets enough credibility, such opportunities would actually materialize. It could be a bit like Periodic Videos, but for molecular biology and physics, and backed by OurBigBook text/tree with minimal openly licensed videos. The fact that such opportunities are essentially impossible outside of the boredom of the university system is something we should really change about education.

Scott Hassan's shitty telepresence robot startup. Looking at the demos it is so painfully obvious why they failed, that feeble tall screen on wheels. But hindsight is 20/20... It is almost as bad as OurBigBook.
The most notable usage of the product is Snowden Snowbot, which is sad, the product name seems to have been "Beam". Who would use that if not for theatrics with an exilee when everyone already has a screen in front of their face all the time?[ref]
