LOLOL!!! I just love it!!!!
"Some wag" has a spectacular sense of humor; and it's definitely "contagious." :^)
Imaginary numbers are definitely "cool." They are the reason for the Y-axis (the vertical extension) on the Cartesian plane. Otherwise, we'd be "stuck" only with the X-axis (the horizontal extension)....
Stephen Hawking has had a field day with imaginary numbers, using them to justify his concept of imaginary time. Which concept he evidently needs to obviate any idea of a beginning of time.
Which is so strange to me; for Hawking and Roger Penrose were the very men who confirmed, to a very high degree of mathematical certainty, that the Universe did, indeed, have a beginning in time.
Go figure!
Thank you ever so much for writing, dear grey_whiskers!
