Fourier transform by Ciro Santilli 35 Updated +Created
Continuous version of the Fourier series.
Of course, every function defined on a finite line segment (i.e. a compact space).
Therefore, the Fourier transform can be seen as a generalization of the Fourier series that can also decompose functions defined on the entire real line.
As a more concrete example, just like the Fourier series is how you solve the heat equation on a line segment with Dirichlet boundary conditions as shown at: Section "Solving partial differential equations with the Fourier series", the Fourier transform is what you need to solve the problem when the domain is the entire real line.
Conjecture by Ciro Santilli 35 Updated +Created
A conjecture is an open problem in mathematics for which some famous dude gave heuristic arguments which indicate if the theorem is true or false.

Diode by Ciro Santilli 35 Updated +Created
Ideally can be thought of as a one-way ticket gate that only lets electrons go in one direction with zero resistance! Real devices do have imperfections however, so there is some resistance.
First they were made out of vacuum tubes, but later semiconductor diodes were invented and became much more widespread.

Education is broken by Ciro Santilli 35 Updated +Created
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:

Peter Gregory from Silicon Valley shows his hate for university in a fake TED talk
. Source. Key moment: someone from the crowd cries:
The true value of a college education is intangible!
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.
