    Complex projective space ℂP¹ can be seen as the compactification of the complex plane ℂ easily as follows. Define S:ℂ→ℂP¹ (stereography!) by S(z) = [z,1] where [z,w] is the complex line thru the point (z,w)≠0. The point [1,0] then plays the role of infinity.

  19. x became associated with unknown quantities because the printer was running out of letter and choose x over y and z 🤯 From the book “Here’s Looking at Euclid”

    In La géométrie Descartes introduces what has become standard alge-
braic notation. It is the first book that looks like a modern math book
full of as, b's and c's and x's, y's and 2s. It was Descartes's decision to use
lowercase letters from the beginning of the alphabet for known quanti
ties, and lowercase letters from the end of the alphabet for the unknowns.
When the book was being printed, however, the printer started to run out
of letters. He inquired if it mattered if «, y or z was used. Descartes replied
not, so the printer chose to concentrate on x, since it is used less frequently
in French than y or z. As a result, × became fixed in math- and the wider
culture- as the symbol for the unknown quantity. That is why paranormal
happenings are classified in the X-files and why Wilhelm Röntgen came
up with the term X-ray.
