As far as I remember, houses in north Atlanta (either side of p'tree, near buckhead), didn't have sidewalks b/c maids would/should walk in the streets. Not that this is right, no! It was a fact of the segregated city.

Needless to say, both the algebra and the calculus fact have to do the the change in volume of an n-dimensional (hyper)-cube.
The produce rule works the same way, but gaining intiution about these hyper volumes is tricky.

Try completing the square
A(x^2 + B/A x) +C= A[ (x+B/(2A))^2 - B^2/4A^2] + C
= A(x+B/(2A))^2 -[ (B^2 -4AC)/4A]=0
(x+B/(2A))^2= [B^2 - 4AC]/ (4A^2)
x =[ -B \pm \sqrt[B^2-4AC]] / 2A

Do you suppose that the #daughterf^cker forgot the word
"ingenue" and quickly substitutued "enigma?" In general,
he had the vocabulary of a 5th grader. Ingenue would make more sense in the context of the birthday card. And, frankly enigma just sounds stupid.

Thank you very much for writing these. The Taxicab article was charming. It's the only one I have taken the time to read so far.

Didn't anyone else noticed that on Friday, #trumpisadaughterf^cker stopped the media from talking about Epstein and start talking about his corruption wrt firing the BLS manager? Media took the bait. Maxwell got moved to a club-med prison. Crisis management: pile one crisis on top of the other.

Consider the metaphor/clique "bird's-eye view." Birds in the morning seem to be scooping insects and spiders from the air that are too tiny for human eyes to see. But do birds see fine details that we don't? Think of a hawk hunting her prey.
I am very grateful for another gentle introduction!

One can show: Somebody told me this. Or maybe there is somebody who can do this. In the best case, it took me several weeks and a large number of mistakes to be able to do this.

A well-known mathematical fact is like a famous mathematician. Both are oxymoronic. Emphasis on "moron."
