韦编三绝 is a chengyu that means "to study diligently", i.e. to read so much to the point that your book starts to wear down.
There is a Chinese Wiki page for this song: zh.wikipedia.org/wiki/韦编三绝 which says it dates from the early Qing dynasty

Ciro Santilli 35 Updated 2025-04-24 +Created 1970-01-01So that he can work full time on OurBigBook.com and revolutionize advanced university-level science, technology, engineering, and mathematics eduction for all ages.
Donating to Ciro is the most effective donation per dollar that you can make to:
- improve hardcore university-level STEM education for all ages
- help make every child into the next Nobel Prize/Fields Medal/deep tech unicorn co-founder
Ciro's goal in life is to help kids as young as possible to reach, and the push, the frontiers of natural sciences human knowledge, linking it to applications that might be the the next big thing as early as possible. Because nothing is more motivating to students than that feeling of:rather than repeating the same crap that everyone is already learning.
To do this, Ciro wants to work in parallel both on:
- the multi-user website e-learning platform of OurBigBook.com
- creating amazing teaching content that motivates that platform, and that deeply interests Ciro, notably quantum mechanics and its related applications:
- quantum computing
- molecular biology
- condensed matter physics and chemistry
- slightly more theoretical stuff in somewhat related fields of:
- continue to dump his brain/research in areas Ciro has expertise in: software engineering and open source software
Ciro believes that this rare combination of both:produces a virtuous circle, because Ciro:
- proven passion and capability to learn and teach science, technology, engineering, and mathematics subjects
- proven programming skills, including web development
- wants to learn and teach, so he starts to create content
- then he notices the teaching tools are crap
- and since he has the ability to actually improve them, he does
As explained at OurBigBook.com and high flying bird scientist, Ciro is most excited to make contributions at the "missing middle level of specialization" that lies around later undergrad and lower grad education:in a way that is:
But on that middle sweet spot, Ciro believes that something can be done, in such as way that delivers:
- beauty
- power
- in your face, without requiring you to study for a year
- but also giving enough precision to allow you to truly appreciate the beauty of the subjectCiro's programming skills can also be used to create educational, or actually more production-like, simulations and illustrations.
Ciro believes that today's society just keep saying over and over: "STEM is good", "STEM is good", "STEM is good" as a religious mantra, but fails miserably at providing free learning material and interaction opportunities for people to actually learn it at a deep enough level to truly appreciate why "STEM is good". This is what he wants to fix.
The following quote is ripped from Gwern Branwen's Patreon page, and it perfectly synthesizes how Ciro feels as well:
In addition to all of this, financial support also helps Ciro continue his general community support activities:
- writing and updating his amazing Stack Overflow answers: Section "Ciro Santilli's Stack Overflow contributions"
- saving the world from the CCP: Section "Ciro Santilli's campaign for freedom of speech in China"
Equation 1.
Lorentz force
. A little suspicious that it bears the name of Lorentz, who is famous for special relativity, isn't it? See: Maxwell's equations require special relativity.
Pinned article: ourbigbook/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.
