async (JavaScript) by Ciro Santilli 37 Updated 2025-07-16
async is all present in JavaScript for two reasons:
Like PCR, but does not require thermal cycling. Thus the "isothermal" in the name: iso means same, so "same temperature".
Not needing the thermo cycling means that the equipment needed is much smaller and cheaper it seems.

This is perhaps the most popular version of Great doubt in 21st century China
Fuller quote as seen e.g. at: www.hrfjw.com/fjrw/hcrw/ywfs/324750.html
大疑大悟,小疑小悟,不疑不悟
translation;
Great doubt, great underestanding. Small doubt, small understanding. No doubt, no understanding.

This is where Ciro Santilli stored his code since he started coding nonstop in 2013.
He does not like the closed source aspect of it, but hey, there are more important things to worry about, the network effect is just too strong.

While most of this is useless as you would expect from the channel, it does give one key idea: you can change charge locally, but things somehow still work out.
And this has something to do with the general intuition of special relativity that only local measures make much sense, as evidenced by Einstein synchronization.
Hyperfine structure by Ciro Santilli 37 Updated 2025-07-16
Small splits present in all levels due to interaction between the electron spin and the nuclear spin if it is present, i.e. the nucleus has an even number of nucleons.
As the name suggests, this energy split is very small, since the influence of the nucleus spin on the electron spin is relatively small compared to other fine structure.
TODO confirm: does it need quantum electrodynamics or is the Dirac equation enough?
The most important examples:
Equations of motion by Ciro Santilli 37 Updated 2025-07-16
These are the final equations that you derive from the Lagrangian via the Euler-Lagrange equation which specify how the system evolves with time.
It is non-trivial to determine what is the smallest legal ELF file, or the smaller one that will do something trivial in Linux.
In this example we will consider a saner hello world example that will better capture real life cases.
