Quantum control system Updated +Created
Some people call it "operating System".
The main parts of those systems are:
  • sending multiple signals at very precise times to the system
  • reading out some quantum error correction bits and sending error correcting signals back in a control loop

The old man lost his horse Updated +Created
Another notable reference is in Lost Horse LLC, MacKenzie Bezos's charity instrument.
Breakdown:
  • 塞翁 sai4 weng1: TODO his name?
  • 失马 shi1 ma3: lost horse
  • 焉知 yan1 zhi1: who knows, literary
  • 非福 fei1 fu2: bad (or) good

Zen master and the little boy scene from Charlie Wilson's War
. Source. This is how Ciro Santilli first heard the old man lost his horse! The scene happens after the Americans seem to have had sucess in arming the Taliban in the 1980s to fight the Soviets, and then they decide to stop all monetary help to rebuild the country, which then leads to a terrorism threat many years later.

High Mountain and Flowing Water Updated +Created
Composed by Bo Ya for the guqin.
But there is an awesome guzheng adaptation which is perhaps better known in modern times, partly because it is not as long/slow. TODO origin.

Electronic band theory Updated +Created
How are the bands measured experimentally?
Why are there gaps? Why aren't bands infinite? What determines the width of gaps?

Leonard Susskind Updated +Created
The bald confident chilled out particle physics guy from Stanford University!
One can't help but wonder if he smokes pot or not.
Also one can't stop thinking abot Leonard Hofstadter from The Big Bang Theory upoen hearing his name.

Dance of the Yi People Updated +Created
Composed by Wang Huiran in 1960.
The Yi people are one of the 55 Chinese ethnic minorities officially recognized by the Chinese government.

Quantum advantage Updated +Created
Similar to quantum supremacy, but add the goal that the computation must be useful, i.e. make money or solve some open mathematical problem, Ciro Santilli's wife was quite excited about the possibility of finding some counter examples in number theory with quantum computers.

Integrated circuit Updated +Created
It is quite amazing to read through books such as The Supermen: The Story of Seymour Cray by Charles J. Murray (1997), as it makes you notice that earlier CPUs (all before the 70's) were not made with integrated circuits, but rather smaller pieces glued up on PCBs! E.g. the arithmetic logic unit was actually a discrete component at one point.
The reason for this can also be understood quite clearly by reading books such as Robert Noyce: The Man Behind the Microchip by Leslie Berlin (2006). The first integrated circuits were just too small for this. It was initially unimaginable that a CPU would fit in a single chip! Even just having a very small number of components on a chip was already revolutionary and enough to kick-start the industry. Just imagine how much money any level of integration saved in those early days for production, e.g. as opposed to manually soldering point-to-point constructions. Also the reliability, size an weight gains were amazing. In particular for military and spacial applications originally.

Business film Updated +Created
Ciro Santilli defines a "business film" as a film about business, enterprises or entrepreneurship. Political thrillers are closed related as well.
This is one of his favorite film genres!
Some lists:
Samurai cinema Updated +Created
Chanbara (チャンバラ).
Those movies are "all the same". A quasi lone superhuman samurai with a good inside but painful problems helping out random people, mostly villagers in trouble and bitches in debt.
Modulation Updated +Created
Modulation basically means encoding data on a carrier wave.
Image that we are at a point in history where spark-gap transmitters can send Morse code.
But now people want to send voice. How to do it?
It would not be practical without modulation: Why can't you send voice without modulation?

Register transfer level Updated +Created
Register transfer level is the abstraction level at which computer chips are mostly designed.
The only two truly relevant RTL languages as of 2020 are: Verilog and VHDL. Everything else compiles to those, because that's all that EDA vendors support.
Much like a C compiler abstracts away the CPU assembly to:
  • increase portability across ISAs
  • do optimizations that programmers can't feasibly do without going crazy
Compilers for RTL languages such as Verilog and VHDL abstract away the details of the specific semiconductor technology used for those exact same reasons.
The compilers essentially compile the RTL languages into a standard cell library.
Examples of companies that work at this level include:
