LC circuit Updated 2025-07-16
When Ciro Santilli was studying electronics at the University of São Paulo, the courses, which were heavily inspired from the USA 50's were obsessed by this one! Thinking about it, it is kind of a cool thing though.

LC circuit dampened oscillations on an oscilloscope by Queuerious Guy (2014)
Source. Finally a video that shows the oscillations without a driving AC source. The dude just move wires around on his breadboard manually, first charging the capacitor and then closing the LC circuit, and is able to see damped oscillations on the oscilloscope.

Video 4. Source. Exactly what you would expect from an Eugene Khutoryansky video. The key insight is that the inductor resists to changes in current. So when current is zero, it slows down the current. And when current is high, it tries to keep it going, which recharges the other side of the capacitor.
TEM vs SEM Updated 2025-07-16
TEM: sample has to be very thin, you get a 2D image. Higher resolution possible.
SEM: sample does not need to be ultra thin, you get a 3D image. Lower resolution possible.

The Scanning Electron Microscope by MaterialsScience2000 (2014)

Cryogenic electron microscopy Updated 2026-08-21
This technique has managed to determine protein 3D structures for proteins that people were not able to crystallize for X-ray crystallography.
It is said however that cryoEM is even fiddlier than X-ray crystallography, so it is mostly attempted if crystallization attempts fail.
By looking at Figure 1. "A cryoEM image", you can easily understand the basics of cryoEM.
We just put a gazillion copies of our molecule of interest in a solution, and then image all of them in the frozen water.
Each one of them appears in the image in a random rotated view, so given enough of those point of view images, we can deduce the entire 3D structure of the molecule.
Ciro Santilli once watched a talk by Richard Henderson about cryoEM circa 2020, where he mentioned that he witnessed some students in the 1980's going to Germany, and coming into contact with early cryoEM. And when they came back, they just told their principal investigator: "I'm going to drop my PhD theme and focus exclusively on cryoEM". That's how hot the cryo thing was! So cool.

Education is broken Updated 2026-01-30
Once Ciro was at a University course practical session, and a graduate was around helping out. Ciro asked if what the graduate did anything specifically related to the course, and they replied they didn't. And they added that:
One has to put the bread on the table.
Even though Ciro was already completely disillusioned by then, that still made an impression on him. Something is really wrong with this shit.
Other people that think that the educational system is currently bullshit as of 2020:

to which the speaker replies:
The true value of snake oil is intangible as well.
IMDb says it's not a cameo. It really looked like one, good acting, but what a missed opportunity. Imagine a Xavier Niel appearance.

David Deutsch on Education interviewed by Aidan McCullen (2019)

Key quote that hits the nail:
[...] the existing assumptions behind educational systems are that the purpose of education is to transmit valuable knowledge faithfully from on generation to the next. From people who already have that knowledge, to people who don't.
So the knowledge is conceived of as a kind of valuable fluid, which you pour from one generation to the next, pour it into their brains.
So right... the purpose of education is not to teach facts. The purpose of education is to propose ways of thinking, which students themselves must try to apply and decide if it suits them! And use the patterns of thinking that are useful to reach their goals.
Like Noam Chomsky, he proposes education has been a system of indoctrination more than anything else e.g. twitter.com/daviddeutschoxf/status/1406374921748496386:
All compulsory education, "tough" or not, "love" or not, in camps or not, and whether it "traumatises" or not, is a violation of human rights.
At twitter.com/DavidDeutschOxf/status/1051475227476185089 another good quote by Churchill:
Headmasters have powers at their disposal with which Prime Ministers have never yet been invested.
The same video also mentions in passing that john Wheeler used to be Deutsch's boss, but I can't find a reference for it very easily.

Quote selection by Charles Bukowski (2016)
Source.
Generally speaking, you're free until you're about 4 years old. Then you go to grammar school and then you start becoming... oriented and shoved into areas. You lose what individualism you have, if you have enough of course, you retain some of it... Then you work the 8 hour job with almost a feeling of goodness, like you're doing something. Then you get married like marriage is a victory, and you have children like children is a victory... Marriage, birth, children. It's something they have to do because there's nothing else to do. There's no glory in it, there's no steam, there's no fire. It's very, very flat... You get caught into the stricture of what you're supposed to be and you have no other choice. You're finally molded and melded into what you're supposed to be. I didn't like this.

Gifted education Updated 2025-07-16
If school weren't bullshit, 99% of students would be in gifted education for what they truly love and are good at.
What is sad about many programs is that they are exclusivist and non scalable, selecting people some how and non scalably educating them. We need a more "here's some projects let's do them whoever can" approach to things, maybe like Google Summer of Code.
School Updated 2025-07-16
Basically the same remarks as for university, just 10 times more useless, see also: Section "Motivation".

University Updated 2025-09-09
One major issue is that teachers don't have the right incentive to, nor are selected to, teach well. Thus the existence of Rate My Professors! But we can do better...
Which is why Ciro Santilli wants to destroy its current format with OurBigBook.com. He believes that we can find a more efficient organization to achieve both the social and research functions of university, by first doing as much as possible online
