Apparently they had a separate URL as just scitable.com, so they were somewhat serious about it before shutting it down.
As of 2022 marked:
This page has been archived and is no longer updated
RIP.
www.nature.com/scitable/blog/student-voices/ has last entry 2015, so presumably that's the shutdown year.
Self description:
Using our platform, you can customize your own eBooks for your students. Create an online classroom. Contribute and share content and connect with networks of colleagues.
so quite related to OurBigBook.com.
Wikipedia dumps by Ciro Santilli 40 Updated 2025-07-16
Per-table dumps created with mysqldump and listed at: dumps.wikimedia.org/. Most notably, for the English Wikipedia: dumps.wikimedia.org/enwiki/latest/
The tables are "documented" under: www.mediawiki.org/wiki/Manual:Database_layout, e.g. the central "page" table: www.mediawiki.org/wiki/Manual:Page_table. But in many cases it is impossible to deduce what fields are from those docs.
MOOCs are a bad idea. We don't want to simply map the pre-computer classroom to the Internet. The Internet allows, and requires, fundamentally new ways to do things. More like Stack Overflow/Wikipedia. More like OurBigBook.com.
OpenStax by Ciro Santilli 40 Updated 2025-07-16
These people have good intentions.
The problem is that they don't manage to go critical because there's to way for students to create content, everything is manually curated.
You can't even publicly comment on the textbooks. Or at least Ciro Santilli hasn't found a way to do so. There is just a "submit suggestion" box.
This massive lost opportunity is even shown graphically at: cnx.org/about (archive) where there is a clear separation between:
  • "authors", who can create content
  • "students", who can consume content
Maybe this wasn't the case in their legacy website, legacy.cnx.org/content?legacy=true, but not sure, and they are retiring that now.
Thus, OurBigBook.com. License: CC BY! So we could re-use their stuff!
TODO what are the books written in?

After Ciro Santilli got a lot of attention on Hacker News news.ycombinator.com/item?id=19428700 his Stack Overflow account was suspended for 3 days web.archive.org/web/20190320163458/https://stackoverflow.com/users/895245/ciro-santilli-新疆改造中心-六四事件-法轮功 and he received a magic notification that led to a private message:
Hello,
I'm writing in reference to your Stack Overflow account:
I don't understand why you are actively promoting and assisting people to commit fraud on the site.
I've removed this from your profile github.com/cirosantilli/stack-overflow-vote-fraud-script and do not expect you to post it around the site.
I'm suspending you to gain your attention on this matter.
We have temporarily suspended your account; you may return after 3 days.

Ciro's reply was:
Hi mods,
Reply and unsuspend quickly followed, with link still removed:
I suspended you to get your attention. Your attitude about going to Twitter about it does not bode well with me.
Feel free to have whatever you want in your GitHub repo. Just don't advertise tools to make it easier for people to circumvent the rules. As easy or as hard as it may be to circumvent them, you're handing it to people who may not be capable of doing so. It doesn't help.
Don't make threats to upload on an anonymous account. Accounts created to circumvent previous warnings are not welcomed on the site.
We don't need a meta thread to discuss whether it's ok to post voting fraud links in your profile and we definitely don't need to give it anymore publicity.
I'll unsuspend you, now we've had this discussion.
Regards,
A meta thread was later created by Yvette, kudos, to which Ciro answered with the correct unpopular answer that will be downvoted to oblivion: meta.stackoverflow.com/questions/381577/is-it-ok-to-have-links-on-how-to-create-sock-puppets-and-gain-rep-fraudulently-i/381635#381635
Yvette had also previously deleted one or two of Ciro's answers for being duplicates, which is a policy Ciro is against: if the questions are not dupes, a single answer might still directly reply to both of them.
Yvette later announced that she was leaving the website: meta.stackoverflow.com/questions/399495/leaving-the-site-and-the-network-mid-election-is-not-the-best-but-theres-no. This is evil, but Ciro was happy. He does not mean harm to Yvette, but in their limited interaction, Ciro disagreed with her choices.

Street reclamation by Ciro Santilli 40 Updated 2025-07-16
Only people who need to drive a car should be allowed to drive a car anywhere near a city, e.g. people who work door to door, people who are disabled, etc.
Countryside driving is fine. If going to a city, you just have to drive to a parking outside of the city where you then take the public transport. And those who live in cities must leave their cars there too.
Everyone else must walk or cycle from home to public transport.
Cars just destroy everything, they make everything ugly:
  • this was extremely clear to Ciro Santilli as a cyclist. He previously lived in a place with few cars and the countryside was so pleasant. Then he moved to a place with more cars and it was shocking. It's a mixture of pollution, noise, and the fact that roads cut up the countryside that just make things not pleasant at all. Dual lane roads in particular are just a terrible thing. You can hear them from afar, much before you see them.
    You can just see as tiny little villages surrounding the bit city and it's oversized motorways are more or less homogenized into one big city mass, the process is clearly visible as you cycle out of the big city and the villages become nicer and more unique as you go along further out.
  • even within cities, cars completely dehumanize the streets. For example, Ciro once lived in a small dead end street, and he would have gladly opened his front window more often to meet the neighbours. But just the noise of cars passing by every so often makes it impractical to work like that.
The Zatoichi effect applies well to the problem of cyclists:
  • they are not really pedestrians, and pedestrian paths are not suitable to them because they are too narrow, of not smooth, or curved. But pedestrians will always have enough political power to have their paths, because they live around the paths
  • they are not really motor vehicles, because motor vehicle paths are too wide and too fast for them. But motor vehicles will always have enough political power to have their paths, because people are lazy and stupid, and because as the world stands, individually you just don't have any reasonable choice to go anywhere.
This is the main drama faced by cyclists.

Magic Aids vs. Magic Rainbows by Magic Aids (2018)
Source. In this amazing video Magic Aids makes fun of Wizards for forcing him to change is Magic Online handle from Magic Aids to something else due to the AIDS part. He claims the Aids is not meant as a reference to the disease, but just as in "memory aid". Ciro doubts this wasn't intentional. But the video is still amazing, and happens to involve a sex doll dressed as Liliana Vess squirting glitter from her vagina. Wizards must love this guy. It is also a good criticism of political correctness in general. This is a work of art.
Dohkwibuhch is a term from the Native American Seneca language. It translates to "the place where things are broken" and refers to the location of a historic Seneca village known for its significance in the culture and history of the Seneca people.
James B. Gibson, an astronomer renowned for his contributions to the field, particularly in the realms of planetary science and astrophysics, has made several key discoveries throughout his career. His work has often focused on understanding the dynamics of celestial bodies, the formation of planets, and the nature of exoplanets.
Igor Irodov is a notable name primarily associated with the field of physics education. He was a Soviet physicist and educator, best known for his work in creating a series of physics problem books that have been widely used by students and educators. His most famous book, "Problems in General Physics," contains a wide range of problems and exercises designed to challenge and enhance the understanding of physics concepts.
Mothur is a software package designed for the analysis of microbial communities, particularly those defined by DNA sequence data from high-throughput sequencing technologies, such as 16S rRNA gene sequences. It was developed to provide a comprehensive and user-friendly tool for researchers studying microbial ecology and diversity. Key features of Mothur include: 1. **Versatility**: It supports various steps in the analysis pipeline, including data preprocessing (e.g.
Computational creativity is an interdisciplinary field that explores the creative capabilities of computer systems and algorithms. It involves the study and development of computer programs that can generate novel and valuable ideas, concepts, artifacts, or solutions, typically associated with human-like creativity. Key aspects of computational creativity include: 1. **Algorithmic Creativity**: Developing algorithms that can produce creative outputs, such as poetry, artwork, music, or even scientific theories.
Hydroinformatics is an interdisciplinary field that combines hydrology, computer science, and information technology to enhance the understanding, management, and decision-making processes related to water resources. It utilizes computational tools, models, and data analysis techniques to study and solve various problems associated with hydrological systems, including water quality, water supply, flood forecasting, and watershed management.
The Todd–Coxeter algorithm is a method used in group theory, specifically for computing the orbit and stabilizer of elements in a permutation group, and for finding a presentation of a group given by generators and relations. It's particularly useful in the study of finite groups and is often used in computational group theory.
The FitzHugh-Nagumo model is a mathematical model used to describe the electrical activity of excitable cells, such as neurons and cardiac cells. It's a simplification of the more complex Hodgkin-Huxley model, which describes action potentials in neurons. The FitzHugh-Nagumo model captures the essential features of excitability and is often used in theoretical biology, neuroscience, and studying various types of wave phenomena in excitable media.

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!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
