When the École Polytechnique mathematics department didn't let Ciro Santilli do his internship of choice due to grades by Ciro Santilli 40 Updated 2025-07-16
Ciro Santilli 40 Updated 2025-07-16This was one of the only bad experience Ciro had at Polytechnique, besides the inevitable fear of not graduating.
Ciro wanted to do a robotics internship in Germany, linked to his interests in artificial general intelligence, see also: Section "Ciro's 2D reinforcement learning games".
But the head of the applied mathematics department Polytechnique prevented him from going because Ciro didn't have the necessary grades, even though the Germans had already agreed to it: he had a C, but he needed a B. As mentioned at École Polytechnique, most Brazilians had crappy grades due to their Polytechnique-incompatible background.
This was done because in the past students with bad grades had abandoned their internships halfway and given foreigners a bad impression of Polytechnique.
It is impossible to say if the head of department really agreed with this bullshit policy, or if it was something beyond his powers and he hid his true opinion, but it felt like the agreed.
What an extremely limited view!!!
To leave the worse, the worse. To assume that grades mean anything!
And thus Ciro had to choose a last moment internship that he hated, rather than becoming the greatest roboticist that ever lived, and did terribly at it.
At least on the other hand Ciro learnt Python instead of working at the internship, and became the greatest programming tutorial writer that ever lived. Maybe.

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.

Source. - 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.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
