In many countries scientific-funding panels are totally corrupt anyway... Shit happens to shit.

The question of what an electron really is, is still open as far as I know. Even the question of whether it's a "particle", is still open. In many or most theories the question of "what it is" is somewhat bypassed. In quantum field theory you describe electrons as a field (like the electromagnetic field), but all fields have the peculiar property that they show energy exchanges in very localized, point-like regions of space โ that's why you can think of them as particles sometimes. Take a look at Wald's book to get an idea.
There are even still open theories that try to describe electrons as mini charged black holes; not to speak about strings, and so on...
The usual misleading sensationalistic title. It isn't the "shape of the electron" at all. A less misleading โ but still not quite correct โ explanation is that they have determined the statistical distribution of electron quantum states in a material. Very roughly speaking, it tells us where we're more or less likely to find an electron in the material, and in what kind of state. Somewhat very distantly like a population density graph on a geographical map. Determining such a population density doesn't mean "revealing the shape of a person".
The paper can also be found on arXiv. What they determine is the so-called quantum geometric tensor. I find the paper's abstract also misleading:
The Quantum Geometric Tensor (QGT) is a central physical object...
but it's a statistical object more than a "physical" one.
It's a very neat and important study, and I don't understand the need to be so misleading about it :(
Cheers! for some reason my search didn't bring that up!
Unfortunately they cannot yet be resized on the fly, as instead some vertical-tab extensions allow you to do. But it's a step in the right direction!
Cheers! ๐ Unfortunately it's the same as on Sci-Hub, the "accepted version". It'll have to do.
Restored! Maybe worth a post update?
It's just part of a player's roleplay.
"Ethical and legal objections". The point in this case is that what's legal is unethical, and what's ethical is illegal. Analogous to other situations through history and countries, for example in the USA when it was illegal for black people to sit in certain parts of a bus, or in Germany when marriage with Jewish people was illegal.
As human beings, it's always important to make the ethical choice.
I'm actually a physics teacher ๐ In fact, as I write in the post, these questions are more about self-reflection. They bring to light some interesting points or issues about Newtonian mechanics and the way we teach it.
