It’s actually obvious and might fall under the “Duh!” heading for some, but it only recently sunk in on me that the Born Rule is really just another case of the Pythagorean theorem. The connection is in the way the coefficients of a quantum superposition, when squared, must sum to unity (one).
For that matter, Special Relativity, which is entirely geometric, is yet another example of the Pythagorean theorem, but that’s another story. (One I’ve already told. See: SR #X6: Moving at Light Speed)
The obvious connection is the geometry behind how a quantum state projects onto the basis eigenvectors axes.

It’s hard to express how weird the year number 2023 seems. (I can go on about it a little because it’s 
So. Here we are in 2023. Weird. Very weird. As I’ve said many times, I remember wondering whether the year 1984 would turn out to be anything like its infamous eponymous book. And the year 2001, also famous but more from the movie than the book, once seemed like the very distant future to me.
I’m generally not one for traditions or custom. I tend to see these as the enemies of thought and imagination. (Ralph Waldo Emerson: “A foolish consistency is the hobgoblin of little minds.”) I have always craved the new, the roads I haven’t yet traveled. Trying a new restaurant is more fun than revisiting an old haunt.
