Numerous number systems beyond the real:
complex numbers, octonions, omnions which can eat whole black
      holes.
It's axiomatic that your personal history, preferences, how you feel
account for nothing at all.

20th century experiments demonstrated that electrical charge is
      quantized; that is, it comes in
multiples of individual small units called the elementary charge, e,
      approximately equal to 1.602
x 10-19 coulombs (except for particles called quarks which have
      charges that are multiples of
1/3e).

Why has the experimentalism of the avant-garde, which has failed in
      the novel, succeeded in
poetry? Because poetry is always experimental; while the novel, on
      the contrary, by its nature,
cannot be . . . which is to say that experimentalism is synonymous
      with poetry, and that applied
to the novel, it leads simply to the substitution of the novel with
      poetry. --Alberto Moravia

Man made the town, Fibonacci inflated zero to be the wheel
around which the universe turns and language is the soul
walking and talking quietly or going angrily to war.
"Counting is in its very essence magical, if any human practice is at all.
      For numbers are things no one has ever seen or heard or touched."
      As are words.

Joan Didion thought the scariest stanza in all of poetry
begins Row, row, row your boat gently
down the stream. The elements, the material penumbra,
irresolvable for the mortal, readily dissolve in words and numbers.
