Ciro Santilli @cirosantilli 35

Gospel of Matthew 4:4:

Ciro Santilli's mother loves that one. Even though she was constantly worried that if Ciro had studied physics he would be poor and starve, a factor which led him to study engineering instead, one of the greatest mistakes of his life. don't be a pussy.

Many subjects have changed very little in the last hundred years, and so it is mind-blowing that people have to pay for books that teach them!

If computers are bicycles for the mind, Ciro wants this website to be the Ferrari of the mind.

Since Ciro Santilli was young, he has been bewildered by the natural sciences and mathematics due to his bad memory.

The beauty of those subjects has always felt like intense sunlight in a fresh morning to Ciro. Sometimes it gets covered by clouds and obscured by less important things, but it always comes back again and again, weaker or stronger with its warmth, guiding Ciro's life path.

As a result, he has always suffered a lot at school: his grades were good, but he wasn't really learning those beautiful things that he wanted to learn!

School, instead of helping him, was just wasting his time with superficial knowledge.

First, before university, school organization had only one goal: put you into the best universities, to make a poster out of you and get publicity, so that more parents will be willing to pay them money to put their kids into good university.

Ciro once asked a chemistry teacher some "deeper question" after course was over, related to the superficial vision of the topic they were learning to get grades in university entry exams. The teacher replied something like:Ciro feels that this was one of the greatest compliments he has ever received in his life. This teacher, understood him. Funny how some things stick, while all the rest fades.

Another interesting anecdote is how Ciro Santilli's mother recalls that she always found out about exams in the same way: when the phone started ringing as Ciro's friends started asking for help with the subjects just before the exam. Sometimes it was already too hopelessly late, but Ciro almost always tried. Nothing shows how much better you are than someone than teaching them.

Then, after entering university, although things got way better because were are able to learn things that are borderline useful.

Ciro still felt a strong emotion of nostalgia when after university his mother asked if she could throw away his high school books, and Ciro started tearing them all down for recycling. Such is life.

University teachers were still to a large extent researchers who didn't want to, know how to and above all have enough time and institutional freedom to teach things properly and make you see their beauty, some good relate articles:

The very fact that you had very little choice of what to learn so that a large group can get a "Diploma", makes it impossible for people to deeply learn what the really want.

This is especially true because Ciro was in Brazil, a third world country, where the opportunities are comparatively extremely limited to the first world.

Also extremely frustrating is how you might have to wait for years to get to the subject you really want. For example, on a physics course, quantum mechanics is normally only taught on the third year! While there is value to knowing the pre-requisites, holding people back for years is just too sad, and Ciro much prefers backward design. And just like the university entry exams, this creates an entry barrier situation where you might in the end find that "hey, that's not what I wanted to learn after all", see also: students must have a flexible choice of what to learn.

We've created a system where people just wait, and wait, and wait, never really doing what they really want. They wait through school to get into university. They wait through university to get to masters. They wait through masters to get to PhD. They wait through PhD to become a PI. And for the minuscule fraction of those that make it, they become fund proposal writers. And if you make any wrong choice along the, it's all over, you can't continue anymore, the cost would be too great. So you just become software engineer or a consultant. Is this the society that we really want?

And all of this is considering that he was very lucky to not be in a poor family, and was already in some of the best educational institutions locally available already, and had comparatively awesome teachers, without which he wouldn't be where he is today if he hadn't had such advantages in the first place.

But no matter how awesome one teacher is, no single person can overcome a system so large and broken. Without technological innovation that is.

The key problem all along the way is the Society's/Government's belief that everyone has to learn the same things, and that grades in exams mean anything.

Ciro believes however, that exams are useless, and that there are only two meaningful metrics:

Even if you wanted to really learn natural sciences and had the time available, it is just too hard to find good resources to properly learn it. Even attending university courses are hit and miss between amazing and mediocre teachers.

If you go into a large book shop, the science section is tiny, and useless popular science books dominate it without precise experiment descriptions. And then, the only few "serious" books are a huge list of formulas without any experimental motivation.

And if you are lucky to have access to an university library that has open doors, most books are likely to be old and boring as well. Googling for PDFs from university courses is the best bet.

Around 2012 however, he finally saw the light, and started his path to Ciro Santilli's Open Source Enlightenment. University was not needed anymore. He could learn whatever he wanted. A vision was born.

To make things worse, for a long time he was tired of seeing poor people begging on the streets every day and not doing anything about it. He thought:which like everything else is likely derived subconsciously from something else, here Schindler's list possibly adapted quote from the Talmud:

So, by the time he left University, instead of pursuing a PhD in theoretical Mathematics or Physics just for the beauty of it as he had once considered, he had new plans.

We needed a new educational system. One that would allow people to fulfill their potential and desires, and truly improve society as a result, both in rich and poor countries.

And he found out that programming and applied mathematics could also be fun, so he might as well have some fun while doing this! ;-)

So he started Booktree in 2014, a GitLab fork, worked on it for an year, noticed the approach was dumb, and a few years later started building this new version. The repo github.com/booktree/booktree is a small snapshot of Ciro's 2014 brain on the area, there were quite a few similar projects at the time, and most have died.

Ciro is basically a librarian at heart, and wants to be the next:

Theory that describes electrons and photons really well, and as Feynman puts it "accounts very precisely for all physical phenomena we have ever observed, except for gravity and nuclear physics" ("including the laughter of the crowd" ;-)).

Learning it is one of Ciro Santilli's main intellectual fetishes.

While Ciro acknowledges that QED is intrinsically challenging due to the wide range or requirements (quantum mechanics, special relativity and electromagnetism), Ciro feels that there is a glaring gap in this moneyless market for a learning material that follows the Middle Way as mentioned at: the missing link between basic and advanced. Richard Feynman Quantum Electrodynamics Lecture at University of Auckland (1979) is one of the best attempts so far, but it falls a bit too close to the superficial side of things, if only Feynman hadn't assumed that the audience doesn't know any mathematics...

The funny thing is that when Ciro Santilli's mother retired, learning it (or as she put it: "how photons and electrons interact") was also one of her retirement plans. She is a pharmacist by training, and doesn't know much mathematics, and her English was somewhat limited. Oh, she also wanted to learn how photosynthesis works (possibly not fully understood by science as that time, 2020). Ambitious old lady!!!

Experiments: quantum electrodynamics experiments.

Combines special relativity with more classical quantum mechanics, but further generalizing the Dirac equation, which also does that: Dirac equation vs quantum electrodynamics. The name "relativistic" likely doesn't need to appear on the title of QED because Maxwell's equations require special relativity, so just having "electro-" in the title is enough.

Before QED, the most advanced theory was that of the Dirac equation, which was already relativistic but TODO what was missing there exactly?

As summarized at: youtube.com/watch?v=_AZdvtf6hPU?t=305 Quantum Field Theory lecture at the African Summer Theory Institute 1 of 4 by Anthony Zee (2004):

That video also mentions the interesting idea that:Therefore, for small timescales, energy can vary a lot. But mass is equivalent to energy. Therefore, for small time scale, particles can appear and disappear wildly.

QED is the first quantum field theory fully developed. That framework was later extended to also include the weak interaction and strong interaction. As a result, it is perhaps easier to just Google for "Quantum Field Theory" if you want to learn QED, since QFT is more general and has more resources available generally.

Like in more general quantum field theory, there is on field for each particle type. In quantum field theory, there are only two fields to worry about:

More precisely, for students whose parents don't live near the school. Or alternatively, online-only courses that offer the same diploma as the presencial version. Or a compromise where the best N% students get accommodation, where N is a parameter of how decent your society is overall.

Since all the learning resources will be available online on OurBigBook.com, or through online 1-to-1 chats with mentors, it might be cheaper for students to work either from their parent's homes if their home has reasonable work conditions: a silent room with reasonable Internet access and no drug addicts in the house.

Alternatively, a public local library with free WiFi would do as well. But there would need to be a strict silence policy enforced, unlike most public libraries we see today. Ciro once saw a bird shaped noise detector that would sing if the noise went above a certain threshold, that was a good idea. Just like linting, it is easier to let machines decide deterministically on subjective questions to reduce useless arguments over who is right. Ciro has even seen libraries where the local council uses the same library open space as a citizen counsel area. What's the fucking point... these people have never done any deep work in their lives.

Then the state only needs to pay transportation and temporary accommodation to attend concentrated month-long laboratory workshop courses and week-long conferences, since the only reason for universities to exist should be the laboratories. In cases where the home conditions are not good enough, the state can either pay for on-demand WeWork-like offices near the student's home, of for a full on-campus accommodation as in a boarding school. What is indispensable is that all students who pass the entry criteria must have such working conditions. Students who stay home can also earn a scholarship to help pay for their rent, food and Internet access.

Anything else is just incredibly unfair to the poor. Ciro Santilli has already witnessed two cases, in developed, and under-developed countries, where very high potential poorer students were forced to work to support themselves in parallel to a demanding degree because their parents couldn't pay their rent on a different city, and the students mental health issues due to this. In one of those cases the student had to abandon the course altogether.

It doesn't help that school has become a pure student-evaluation system, which basically implies putting studets through a lot of useless pressure.

One of the stories that Ciro Santilli's father tells is about how when they were dating, one of Ciro Santilli's mother's greatest wish for her hypotetical child would be that "they should not need to work during their studies as she had". As destiny would have it, Ciro Santilli's family had good conditions and Ciro never thought even once about money. And even then, school still sucked. Imagine without that basic, mandatory, stability!
