Ah, the jewel of computational physics.
Also known as an ab initio method: no experimental measurement is taken as input, QED is all you need.
But since QED is thought to fully describe all relevant aspects molecules, it could be called "the" ab initio method.
For one, if we were able to predict protein molecule interactions, our understanding of molecular biology technologies would be solved.
No more ultra expensive and complicated X-ray crystallography or cryogenic electron microscopy.
And the fact that quantum computers are one of the most promising advances to this field, is also very very exciting: Section "Quantum algorithm".

Git tips / Understand the commit tree Updated 2025-07-16
This is the most important thing to understand Git!
You must:
  • be able to visualize the commit tree
  • understand how each git command modifies the commit DAG

First there were dominant Elmer and Geophysics Corporation of America dominating the market.
Then a Japanese government project managed to make Nikon and Canon Inc. catch up, and in 1989, when Ciro Santilli was born, they had 70% of the market.
youtu.be/SB8qIO6Ti_M?t=240 In 1995, ASML had reached 25% market share. Then it managed the folloging faster than the others:
Option 1) git commit. Doh!!!
Option 2) git rebase. Basically allows you to do arbitrary modifications to the tree. The most important ones are:
Atomic, Molecular and Optical Physics Updated 2025-07-16
AMO is a slightly more general area than condensed matter physics, including related phenomena with smaller numbers atoms and optics. The two terms are however sometimes used as synonyms. The term AMO has gained wide usage and acceptability, see e.g.:
If Ciro had had greater foresight, this might have been what he studied at university!

Autodidacticism Updated 2025-07-16
There are two types of people:
  • those who are autodidacts
  • those who didn't really learn
Some possible definitions:
  • learning without a gun pointed at your head
  • learning from an e-book or video rather than from a talking head 5 rows of chairs in front of you
    How that is different from a video, you tell me.
Automatic programming Updated 2025-10-18
We use the term "automatic programming" to mean "generating code from natural language".
The ultimate high level of which is of course to program with:which is basically the goal of artificial general intelligence, especially according to The Employment Test definition of AGI.
The term has not always had that sense:
automatic programming has always been a euphemism for programming in a higher-level language than was then available to the programmer
sums it up.
But in the current AI boom, this is the sense that matters, so that's what we will go with.
