Germline Updated +Created
It is quite mind blowing when you think about it, that the huge majority of your body's cells is essentially just there to support a tiny ammount of germline, which are the only cells that can actually pass on! It is fun to imagine the cell type tree for this, with a huge branching of somatic cells, and only a few germline going forward.

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:
Gauge theory Updated +Created
The term and idea was first introduced initialized by Hermann Weyl when he was working on combining electromagnetism and general relativity to formulate Maxwell's equations in curved spacetime in 1918 and published as Gravity and electricity by Hermann Weyl (1918). Based on perception that symmetry implies charge conservation. The same idea was later adapted for quantum electrodynamics, a context in which is has even more impact.
Gene expression profiling Updated +Created
Gauge field Updated +Created
A random field you add to make something transform locally the way you want. See e.g.: Video "Deriving the qED Lagrangian by Dietterich Labs (2018)".
Quantum superposition Updated +Created
Quantum superposition is really weird because it is fundamentally different than "either definite state but I don't know which", because the superposition state leads to different measurements than the non-superposition state.
Examples:
Greisen-Zatsepin-Kuzmin limit Updated +Created
GIMP Updated +Created
It's not super easy to use at first.
And it sometimes says that the basic drawing thing you want to do is off the project's scope.
But as you learn more about it and further generalize the concepts, there are often reasonable reasons for those design choices.
And the UI looks good :-)
Examples:
GitHub's replacement of master branch with main (2020) Updated +Created
By GitHub around Black Lives Matter, due to a possible ludicrous relationship with slavery of black people:For the love of God, the word "master" is much more general than black slavery. If you are going to ban it, you might as well ban the word "evil".
Several software projects followed the purge from their codebases, maybe GitHub followed someone else's lead, it's hard to say.
The words "whitelist" and "blacklist" were also targeted.
Ainan Celeste Cawley Updated +Created
His father fought a lot with the stupid educational system to try and move his son to his full potential and move to more advanced subjects early.
A crime of society to try and prevent it. They actually moved the family from Singapore to Malaysia for a learning opportunity for the son. Amazing.
This is the perfect illustration of one of Ciro Santilli's most important complaints about the 2020 educational system:and why Ciro created OurBigBook.com to try and help fix the issue.

TSMC Updated +Created
One of the companies that has fabs, which buys machines from companies such as ASML and puts them together in so called "silicon fabs" to make the chips
As the quintessential fabless fab, there is on thing TSMC can never ever do: sell their own design! It must forever remain a fab-only company, that will never compete with its customers. This is highlighted e.g. at youtu.be/TRZqE6H-dww?t=936 from Video "How Nvidia Won Graphics Cards by Asianometry (2021)".

How Taiwan Created TSMC by Asianometry (2020)
Source. Some points:
  • UCM failed because it focused too much on the internal market, and was shielded from external competition, so it didn't become world leading
  • one of TSMC's great advances was the fabless business model approach.
  • they managed to do large technology transfers from the West to kickstart things off
  • one of their main victories was investing early in CMOS, before it became huge, and winning that market

Wikipedia reads:
Any contributor could create and own new Knol articles, and there could be multiple articles on the same topic with each written by a different author.
so basically exactly what Ciro Santilli wants to do on OurBigBook.com. Ominous.
Like any closed source "failure", everything was deleted. wiki.archiveteam.org/index.php/Knol
Ruth Lawrence Updated +Created
en.wikipedia.org/wiki/Ruth_Lawrence
When Lawrence was five, her father gave up his job so that he could educate her at home.
At Oxford, her father continued to be actively involved in her education, accompanying her to all lectures and some tutorials. Lawrence completed her bachelor's degree in two years, instead of the normal three, and graduated in 1985 at the age of 13 with a starred first and special commendation.

he had tried it once before - with an older daughter, Sarah, one of three children he had by a previous marriage.
That experiment ended after he separated from Sarah's increasingly concerned mother, Jutta. He soon found a woman more in tune with his radical ideas in his next spouse, Sylvia Greybourne
Maxwell's equations are Lorentz invariant Updated +Created
Subtle is the Lord by Abraham Pais (1982) chapter III "Relativity, the special theory" mentions that this fact and its importance (we want the laws of physics to look the same on all inertial frames, AKA Lorentz covariance) was first fully relized by poincaré in 1905.
And at that same time poincaré also immediately started to think about the other fundamental force then known: gravity, and off the bat realized that gravitational waves must exist. general relativities is probably just "the simplest way to make gravity Lorentz covariant".
Note that:
and for that to be true for all possible and then we must have:
i.e. the matrix inverse is equal to the transpose.
Conversely, if:
is true, then
These matricese are called the orthogonal matrices.
TODO is there any more intuitive way to think about this?
How to visualize the commit tree Updated +Created
Generate a minimal test repo. You should get in the habit of doing this to test stuff out.
#!/usr/bin/env bash

mkdir git-tips
cd git-tips
git init

for i in 1 2 3 4 5; do
  echo $i > f
  git add f
  git commit -m $i
done

git checkout HEAD~2
git checkout -b my-feature

for i in 6 7; do
  echo $i > f
  git add f
  git commit -m $i
done
gitk Updated +Created
For the newbs.
Slick? No. But gitk does the job, like any one of the other 100 billion free Git UI viewers out there
gitk master HEAD
https://raw.githubusercontent.com/cirosantilli/media/master/gitk.png
Many IDEs are also implementing this now (e.g. VS Code, Eclipse. Most free IDE GIt implementations are still crap, but that is the future, because you want to edit, view history, edit, view history, commit, edit.
git log --graph Updated +Created
For the strong.
git log --abbrev-commit --decorate --graph --pretty=oneline master HEAD
Output:
* b4ec057 (master) 5
* 0b37c1b 4
| * fbfbfe8 (HEAD -> my-feature) 7
| * 7b0f59d 6
|/
* 661cfab 3
* 6d748a9 2
* c5f8a2c 1
If we also add the --simplify-by-decoration, which you very often want want on a real repository with many commits:
* b4ec057 (master) 5
| * fbfbfe8 (HEAD -> my-feature) 7
|/
* c5f8a2c 1
As we can see, this removes any commit that is neither:
  • under a branch or tag
  • at the intersection of too branches or tags
