It isn't Trump. It's the majority of USA citizens. They voted.
No idea how to read the paper's title. Once upon a time there were things called prepositions, like "of", "for", "with", "on"... Probably now they're too modern-writer reduced cell-activity difficult.
I wonder which server they use. I've only had headaches trying to use Matrix for collaboration, especially if people were on different servers.

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 – 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 – but still not quite correct – 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! 🙏 Unfortunately it's the same as on Sci-Hub, the "accepted version". It'll have to do.
Won't people rebel to this? Where's one's dignity?
