    “…the nonlinear characterization of Billy Pilgrim
    emphasizes that he is not simply an established
    identity who undergoes a series of changes but
    all the different things he is at different times.”

A 2x4 array of squares

This suggests that the above structure
be viewed as illustrating not eight  parts
but rather 8! = 40,320 parts.

Narrative

Filed under: General — m759 @ 2:00 PM

In memory of weather buff Stephen Fybish,
who reportedly died at 80 on August 30.

The Eye of Harvey meets the Eye of Shangri-La

   

Today's New York Times  on Fybish

"Winter was his favorite season. He liked to taste the snow,
'since that’s one of the purer forms of water that we’re likely
to encounter here in the Big Apple,' he said."

Space, Time, Gravity

Or:  An Apple for Marcela

Scene from the college class Astronomy 101 in "Transformers:
Revenge of the Fallen" (June 24, 2009) —

Professor—  "Space. Time. Gravity. " 

          (Bites apple, drops it and kicks it to students.)

Coed (catching apple)—  "Thank you."

Professor to coed—  "Finish that for me."

Professor to students—

"We're going on a journey together, you and I, today.
All you eager, nubile, young minds on the very cusp
of adulthood. And I shall be your consort, your guide,
your chaperone, into the heart of darkness."

the "nubile" link above

The Palpatine Dimension

Filed under: General,Geometry — Tags: — m759 @ 9:00 AM

A physics quote relayed at Peter Woit's weblog today—

"The relation between 4D N=4 SYM and the 6D (2, 0) theory
is just like that between Darth Vader and the Emperor.
You see Darth Vader and you think 'Isn’t he just great?
How can anyone be greater than that? No way.'
Then you meet the Emperor."

See also uses of the word triality  in mathematics. For instance…

A discussion of triality by Edward Witten

Triality is in some sense the last of the exceptional isomorphisms,
and the role of triality for n = 6  thus makes it plausible that n = 6
is the maximum dimension for superconformal symmetry,
though I will not give a proof here.

— "Conformal Field Theory in Four and Six Dimensions"

and a discussion by Peter J. Cameron

There are exactly two non-isomorphic ways
to partition the 4-subsets of a 9-set
into nine copies of AG( 3,2).
Both admit 2-transitive groups.

— "The Klein Quadric and Triality"

Exercise: Is Witten's triality related to Cameron's?
(For some historical background, see the triality  link from above
and Cameron's Klein Correspondence and Triality.)

Cameron applies his  triality to the pure geometry of a 9-set.
For a 9-set viewed in the context of physics, see A Beginning

From MIT Commencement Day, 2011—

A symbol related to Apollo, to nine, and to "nothing"

A minimalist favicon—

This miniature 3×3 square— http://log24.com/log/pix11A/110518-3x3favicon.ico — may, if one likes,
be viewed as the "nothing" present at the Creation.

Khora as Synchronicity

Frontiers of Speculation

 m759 @ 8:02 AM

Peter Woit has a post on Scientific American 's new Garrett Lisi article, "A Geometric Theory of Everything."

The Scientific American  subtitle is "Deep down, the particles and forces of the universe are a manifestation of exquisite geometry."

See also Rhetoric (Nov. 4, 2010) and Exquisite Geometries (May 19, 2009).

This morning's post on khora  and Cardinal Manning, and,
from Hawking's birthday this year, Big Apple.

Within this  post, by leading us to the apple,
Derrida as usual plays the role of Serpent.
