Initially a phenomenological guess to explain the periodic table. Later it was apparently proven properly with the spin-statistics theorem, physics.stackexchange.com/questions/360140/theoretical-proof-of-paulis-exclusion-principle.

And it was understood more and more that basically this is what prevents solids from collapsing into a single nucleus, not electrical repulsion: electron degeneracy pressure!

Main implementations: the same as electronic switches: vacuum tubes in the past, and transistors in the second half of the 20th century.

Died of cancer at age 53. Ciro Santilli just can't help but speculate that it is linked to radioactivity exposure.

No teachers, no courses, no tuition fees. Yes please!!! By Xavier Niel.

Mt. Gox was the first Cryptocurrency exchange in existence, and when it shutdowon in Febrauary 2014 because the website was crap and they got hacked, some people were not happy at all about their missing funds!

A fantastic sounding full time 4-year course that any student could transfer to called that teaches various natural science topics, notably mathematics, physics, chemistry and molecular biology.

Many past students Ciro talked to however share a common frustration with the course: in the first 2 years at least, the "basic cycle", you have infinitely many courses, and no time to study, and no choice of what to study, it is only in the latter 2 years (the advanced cycle) that you get the choices.

Also, if you get low grades in a single subject, your out. And exams are useless of course.

Here's a Quora question in Portuguese about the course: pt.quora.com/Como-funciona-o-tal-do-curso-secreto-da-USP, the only decent answer so far being: pt.quora.com/Como-funciona-o-tal-do-curso-secreto-da-USP/answer/Victor-Soares-31. Very disappointing to hear.

On the advanced cycle, you have a lot of academic freedom. You are basically supposed to pick a research project with an advisor and go for it, with a small amount of mandatory course hours. Ciro was told in 2022 that you can even have advisors from other universities or industry, and that it is perfectly feasible to take courses in another university and validate the course hours later on. Fantastic!!!

Students from the entire University of São Paulo can apply to transfer to it only after joining the university, with the guarantee that they can go back to their original courses if they don't adapt to the new course, which is great!

Not doing it is one of Ciro Santilli's regrets in life, see also: don't be a pussy.

Around 2007, they were in a really shady building of the University, but when Ciro checked in 2021, they had apparently moved to a shiny new entrepreneurship-focused building. Fantastic news!!!

This place has one of the best changes of spawning the first Brazilian Nobel Prize or unicorn.

One of the Brazilians who came to École Polytechnique together with Ciro was from this course. The fact that he is one of the most intelligent people Ciro knows gave further credit to that course in his eyes.

The fundamental intuition about capacitors is that they never let electrons through.

They can only absorb electrons up to a certain point, but then the pushback becomes too strong, and current stops.

Therefore, they cannot conduct direct current long term.

For alternating current however, things are different, because in alternating current, electrons are just jiggling back and forward a little bit around a center point. So you can send alternating current power across a capacitor.

The key equation that relates Voltage to electric current in the capacitor is:So if a voltage Heavyside step function is applied what happens is:More realistically, one may consider the behavior or the series RC circuit to see what happens without infinities when a capacitor is involved as in the step response of the series RC circuit.

ourbigbook.com is a website created by Ciro Santilli.

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.

The source code for ourbigbook.com is present at: github.com/ourbigbook/ourbigbook/tree/master/web

The project documentation is present at: docs.ourbigbook.com#ourbigbook-web-user-manual

This page contains further information about the project's rationale, motivation and planning.

This is good software.

If it only it were written in JavaScript instead of Haskell (!?), then Ciro might have used it as the basis for OurBigBook Markup.

merlijn.sebrechts.be/blog/2020-08-02-why-one-snap-store/ has some very good comments on how snap is more closed than Flatpak.

Snap's permission system is extremely annoying, notably restricting access to home files. They need a popup that says "permission required by app, accept?" urgently!!!

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!

At 100k USD, I quit my job to work full time on it for one year. During this year I will use my contacts with STEM students of a world leading university near where I live and solve as many of their problem sheets as possible, mostly by referring to OurBigBook.com articles I'll be writing. The goal is to get as much STEM knowledge as possible into the world, and highlight how flawed presencial and sequential Higher Education is, while positioning OurBigBook.com as an alternative way to organize humanity's knowledge. Quite grand.

Status: ~144k / 200k USD reached. 1st year locked in and started 1st June 2024 to 31st May 2025^[ref], 2nd year stretch goal open. 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. Donation breakdown:More details: Section "Accounting method"

At 1M USD I retire and work on open STEM education forever.

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.

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.

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.
