I really don't like how science communication is typically done, which is all of the math is stripped out, and all the ideas are told as if they were thought experiements, and it makes it easy to get the impression that what scientists do all day is just think abstractly about stuff.

So that's why I linked the preprint directly. Just note that this is a preprint, and it hasn't yet been peer-reviewed, and, of course, not all of the work is shown in any article, even a scientific one.
