No teachers, no courses, no tuition fees. Yes please!!! By Xavier Niel.
Good Portuguese overview: www.scielo.br/scielo.php?script=sci_arttext&pid=S1806-11172017000300301&lng=pt&tlng=pt
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!
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!!!
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.
Nice, nice place. Natural sciences only, no bullshit.

A Cartan matrix is a square matrix that encodes information about the root system of a semisimple Lie algebra or a related algebraic structure. Specifically, it is associated with the simple roots of the Lie algebra and reflects the relationships between these roots.
Bond hardening refers to a variety of processes or treatments that enhance the bond strength between materials, particularly in the context of adhesives, coatings, or composite materials. It is often associated with improving the mechanical properties and durability of materials through specific treatments or processes that alter the microstructure or increase the bonding effectiveness of the materials involved.
A geomagnetic excursion is a temporary, significant change in the Earth's magnetic field, characterized by a rapid and substantial shift in the position of the magnetic poles. Unlike geomagnetic reversals, which involve a complete flip of the Earth's magnetic field (where the magnetic north and south poles switch places), excursions are generally shorter-lived events that can last from a few centuries to a few thousand years.
Isaiah Berlin was a prominent British philosopher and historian of ideas, known for his writings on political philosophy, freedom, and various aspects of intellectual history. Some of his most notable works include: 1. **"Two Concepts of Liberty" (1958)** - This essay discusses the distinction between negative and positive liberty, influencing liberal thought.
A boom brake is a safety device commonly used in various types of machinery and equipment, particularly in cranes and other lifting devices. It is designed to prevent uncontrolled movements of the boom (the arm or extending part of a crane) in the event of a failure or emergency situation. The boom brake works by applying friction to the boom or its mechanisms, which helps to hold it in place and prevent it from falling or swinging uncontrollably.
Sophus Lie (1842-1899) was a Norwegian mathematician known for his foundational work in the field of continuous symmetry and transformation groups, which has profound implications in various areas of mathematics and theoretical physics. His most significant contribution is the development of what is now known as Lie theory, which studies Lie groups and Lie algebras.
"Both Sides Now" is an album by Australian singer Marina Prior, released in 2017.

Brain-specific homeobox (Bsx) is a gene that encodes a transcription factor involved in the development and function of the brain. Transcription factors are proteins that help regulate the expression of other genes, playing crucial roles in various biological processes, including development, differentiation, and metabolism. The Bsx gene is particularly notable for its role in the development of certain neuronal populations and in the regulation of various brain functions.
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!
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.Figure 1. Screenshot of the "Derivative" topic page.
