Anne Wojcicki Updated 2025-07-16
She's truly passionate about health research and keeping healthy, almost obsessed by it. Also she's strong willed, and energetic. Good traits for founding 23andMe.
- www.vanityfair.com/style/2014/04/sergey-brin-amanda-rosenberg-affair Fantastic painting of the people.
As www.nytimes.com/2017/11/18/style/anne-wojcicki-23andme-genetics.html puts it well:
The Wojcickis grew into Silicon Valley royalty. It’s the sort of family, Anne jokes, where “you’re only a viable fetus once you have your Ph.D.

Source. She's athletic! As mentioned at: www.vanityfair.com/style/2014/04/sergey-brin-amanda-rosenberg-affair. And despite the name, and unlike Sergey, she's completely american as seen from her perfect accent!- youtu.be/pDoALM0q1LA?t=173 coding on garage while they do dishes and burritos
- youtu.be/pDoALM0q1LA?t=331 why she's obsessed with healthcare. Also mentioned at: www.vanityfair.com/style/2014/04/sergey-brin-amanda-rosenberg-affair how she was trying to save Sergei from some of his genetic predispositions
- youtu.be/pDoALM0q1LA?t=571 she really cared about 23andMe, but the public didn't as much as her. She's truly passionate about mining genetic data. Maybe she came a bit early.

OurBigBook.com User acquisition Updated 2025-07-16
The general and ideal user acquisition is of course organic Googling:
- user does not understand his teacher's explanation of a subject
- user Googles into rare specific subject
- looks around, then login/create account with OAuth to leaves a comment or upvote
- notice that you can fork anything
- mind = KABOOM
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!

Does have some gems worth looking at. But generally always too superficial as can be expected from any self-sufficient YouTubber.

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:
Anomalous magnetic dipole moment of the electron Updated 2025-07-16
Richard Feynman Quantum Electrodynamics Lecture at University of Auckland (1979) mentions it several times.
This was one of the first two great successes of quantum electrodynamics, the other one being the Lamb shift.
In youtu.be/UKbp85zpdcY?t=52 from freeman Dyson Web of Stories interview (1998) Dyson mentions that the original key experiment was from Kusch and Foley from Columbia University, and that in 1948, Julian Schwinger reached the correct value from his calculations.
Apparently first published at The Magnetic Moment of the Electron by Kusch and Foley (1948).

Oscillators: RC, LC, Crystal by GreatScott! (2015)
Source. Good video. Contains actual breadboard experiments on oscilloscope and circuit diagrams- youtu.be/eYVOdlK15Og?t=66 RC oscillator on breadboard. Produces rectangular wave. Mentions popular integrated circuit that does it: 555 timer IC.
- youtu.be/eYVOdlK15Og?t=175 LC oscillators allows for higher frequencies. Produces sinusoidal output on MHz range. Uses an amplifier to feed back into input and maintain same voltage. Hard to make reliably on breadboard.
- youtu.be/eYVOdlK15Og?t=315 crystal oscillator. Mentions it acts like an LC oscillators. Shows and equivalent model. Wish he had talked more about them. You need support components around it: similarly to the LC case, the amplifier is generally not packaged in.
