Maybe it is a notation issue.

What is a negative number? What is multiplication? What is a complex "number"? Complex are not even orderable. Is complex addition an overloading of the addition operator. Same with multiplication?

What i squared is -1 ? What does -1 even mean? Is the sign, a kind of operator?

The geometric interpretation help. These are transformations. Instead of 1 + i, we could/should write (1,i)

A lot of math is not very clear because it is not very well taught. The notations are unclear. For instance, another example is: what is the difference between a matrix and a tensor? But that is another debate for anyone who wants to think about it. The definition found in books is often kind of wrong making a distinction that shouldn't really exist more often than not.


Isn't it the mathematics that is lagging? Amplituhedron? Higher dimensional models?

Fun fact: I got to read the thesis of one my uncles who was a young professor back in the 90's. Right when they were discovering bosons. They were already modelling them as tensors back then. And probably multilinear transformations.

Now that I am grown I can understand a little more, I was about 10 years old back then. I had no idea he was studying and teaching the state of the art. xD


Tensors are pretty old in physics; they are a central concept in Einstein's General Relativity.

You can find tensors even in some niche stuff in macroeconomics.


Tensors are like 200 years old in mathematics. Gauss talked about Tensors.

What was new was not tensors. It was the representation in SU of mesons for photon-photon collisions. But even saying that is skimming the surface. I can't read beyond the knowledge gap.

SO(3)*, not SU

Does is overlap with Contributor License Agreement?

Do these administrations still purchase licenses for software or do they just create open source maintained by government employees? How much are they willing to pay? Because people in Europe are notoriously paid less so I am curious of the financial aspect. Also curious about the logistics of ownership and support...

I know that my city's administration has a quite active development department.

I don't know the current salary ranges,but they offer other values like vacation days, Work-Life-Balance (proper time tracking to avoid extra hours etc), part-time.offera, child care options and some other benefits, which most corporations won't give in addition to being the state, which means they won't go bankrupt, won't do reductions in force in the way companies do it, ...


Does getting these roles require French citizenship? Asking for a friend ;)

To work in French civil service (as a fonctionnaire) you need to be a EU/EEA citizen but not necessarily French.

Interesting. Have you ever seen a non-French(/Walloon/Monegasque/French Swiss) person work in French civil service?

I could see there being.. biases that make it much harder in practice. Not particular to France, but anywhere in Europe.

My friend might just start brushing up on their French.


I would say that for most jobs you just need a work permit. Only when doing "core" tasks where one acts on state's authority the barriers are higher.

Isn't that measuring the speed of json encoding instead?


Nice, first time I try this game... Guess I am not a natural.. It's not like othello/reversi haha.


now that you say it :o

Should be astro lakes or something.


Islands is just a catchy name I guess. I always thought the markojs terms for it made sense, but are more technical / less catchy: they called it “full page hydration” -> everything needs to be delivered as js and “component level hydration” -> islands, only specific component sub-trees need to be hydrated.

Then “sub-component level hydration” would be resumability like in qwik where only events and their dependencies get serialised as client js.


Yeah. Well to their defense, it is probably to be understood as islands of interactivity lost in a sea of static elements. The term is definitely more evocative.


Would be great if it could be used as a wasm library... Just saying... Is it? I would actually need and use this.


Tough luck, something is coming from my end at some point this year. The remix guys are coming with something too. You won't force me to useReact, sorry... ;D


There is no loyalty. They eho have the best models win.

The only way remains to try and lock consumers into your ecosystem.
