OurBigBook.com User acquisition Updated 2025-07-16
The general and ideal user acquisition is of course organic Googling:
However, before that point, it is very likely that Ciro will have to physically do some very hard and specific user acquisition work at some University. Maybe there is a more virtual way of achieving this.
This work will involve going through some open set of university lecture notes, and creating a superior version of them on OurBigBook.com, and somehow getting students to notice it and use it as a superior alternative to their crappy lecture notes.
Another very promising route is publishing the answers to old examination questions on the website. It is likely that we will be able to overcome any copyright issues by uploading only the answers to numbered questions. There is a minor risk that these would be considered derivative works of the copyrighted questions. But universities would have to be very anal to enforce a DMCA for that!!!
Getting in contact with students is an epic challenge, as an incredibly deep chasm separates us:
- it is basically impossible to try and approach teachers: how to convince teachers to use CC BY-SA
- and on the other hand, how will you get university students to trust you are not a pedophile and that you actually want to help them?The missing aspect is how to join their main "class communication group", e.g. a WhatsApp or Discord chat they have. That would be the perfect entry point to communicate with the end users. But that entry point is also generally closed exclusively for students, and sometimes lecturers, and will not accept anyone external.Perhaps Ciro would be able to do something with one of the two Universities he attended in the past: École Polytechnique or University of São Paulo. But there was no clear channel in those institutions for that. There is either an "infinitely noisy Facebook with everyone that bothered" or silence, deathly silence and isolation of no contact. The key hard part is getting a per-course granularity chat. Discord Student Hubs are a fantastic initiative in that area. Shame that Discord is an unusable mess with zero ways to select which notifications you care about: Section "Discord email notifications"!One approach method that shows some promise is to follow the Student societies, which often host open events of interest outside of work hours.
Walking with advertisement t-shirts mentioning specific course names in some university location is something Ciro seriously considers, that's how desperate things are. Watch out: docs.ourbigbook.com/#public-relations for T-shirt news!

System of partial differential equations Updated 2025-07-16
In many important applications, what you have to solve is not just a single partial differential equation, but multiple partial differential equations coupled to each other. This is the case for many key PDEs including:

The artist and the politician Updated 2025-07-16
Once upon a time in the 2010's, Ciro Santilli went to an artsy theatre venue in the suburbia of Paris, dragged by his wife then girlfriend of course.
In the venue, there was a politician, who was doing his best to show how much they supported the arts, and there were of course the artists, involved in the play.
The politician would see a political power score on top of every person's head, and would spend an amount of time talking to each person exactly proportional to that score. This meant basically one sentence to us. The words themselves didn't really matter of course, only the time spent, they just have to produce nice sounds.

High level quantum synthesis Updated 2025-07-16
This is a term "invented" by Ciro Santilli to refer to quantum compilers that are able to convert non-specifically-quantum (functional, since there is no state in quantum software) programs into quantum circuit.
The term is made by adding "quantum" to the more "classical" concept of "high-level synthesis", which refers to software that converts an imperative program into register transfer level hardware, typicially for FPGA applications.
