True Grid (continued)

Filed under: General,Geometry — Tags: , — m759 @ 12:00 pm

"Rosetta Stone" as a Metaphor
  in Mathematical Narratives

For some backgound, see Mathematics and Narrative from 2005.

Yesterday's posts on mathematics and narrative discussed some properties
of the 3×3 grid (also known as the ninefold square ).

For some other properties, see (at the college-undergraduate, or MAA, level)–
Ezra Brown, 2001, "Magic Squares, Finite Planes, and Points of Inflection on Elliptic Curves."

His conclusion:

When you are done, you will be able to arrange the points into [a] 3×3 magic square,
which resembles the one in the book [5] I was reading on elliptic curves….

This result ties together threads from finite geometry, recreational mathematics,
combinatorics, calculus, algebra, and number theory. Quite a feat!

5. Viktor Prasolov and Yuri Solvyev, Elliptic Functions and Elliptic Integrals ,
    American Mathematical Society, 1997.

Brown fails to give an important clue to the historical background of this topic —
the word Hessian . (See, however, this word in the book on elliptic functions that he cites.)

Investigation of this word yields a related essay at the graduate-student, or AMS, level–
Igor Dolgachev and Michela Artebani, 2009, "The Hesse Pencil of Plane Cubic Curves ."

From the Dolgachev-Artebani introduction–

In this paper we discuss some old and new results about the widely known Hesse
configuration
  of 9 points and 12 lines in the projective plane P2(k ): each point lies
on 4 lines and each line contains 3 points, giving an abstract configuration (123, 94).

Rosalind Krauss
in "Grids," 1979:

"If we open any tract– Plastic Art and Pure Plastic Art  or The Non-Objective World , for instance– we will find that Mondrian and Malevich are not discussing canvas or pigment or graphite or any other form of matter.  They are talking about Being or Mind or Spirit.  From their point of view, the grid is a staircase to the Universal, and they are not interested in what happens below in the Concrete.

Or, to take a more up-to-date example…."

"He was looking at the nine engravings and at the circle,
checking strange correspondences between them."
The Club Dumas ,1993

"And it's whispered that soon if we all call the tune
Then the piper will lead us to reason."
Robert Plant ,1971

The nine engravings of The Club Dumas
(filmed as "The Ninth Gate") are perhaps more
an example of the concrete than of the universal.

An example of the universal*– or, according to Krauss,
a "staircase" to the universal– is the ninefold square:

The image “http://www.log24.com/theory/images/grid3x3.gif” cannot be displayed, because it contains errors.

"This is the garden of Apollo, the field of Reason…."
John Outram, architect    

For more on the field of reason, see
Log24, Oct. 9, 2006.

A reasonable set of "strange correspondences"
in the garden of Apollo has been provided by
Ezra Brown in a mathematical essay (pdf).

Unreason is, of course, more popular.

* The ninefold square is perhaps a "concrete universal" in the sense of Hegel:

"Two determinations found in all philosophy are the concretion of the Idea and the presence of the spirit in the same; my content must at the same time be something concrete, present. This concrete was termed Reason, and for it the more noble of those men contended with the greatest enthusiasm and warmth. Thought was raised like a standard among the nations, liberty of conviction and of conscience in me. They said to mankind, 'In this sign thou shalt conquer,' for they had before their eyes what had been done in the name of the cross alone, what had been made a matter of faith and law and religion– they saw how the sign of the cross had been degraded."

– Hegel, Lectures on the History of Philosophy ,

"For every kind of vampire,
there is a kind of cross."

Starting Out in the Evening

* The Web version's title has a misprint—
   "living" instead of "lying."

The Shining
of Friday the 13th

From Margalit Fox in today’s New York Times:

“Eddie Barclay, who for three decades after World War II was arguably the most powerful music mogul in Europe and inarguably the most flamboyant, died on [Friday] May 13 in Paris. He was 84….

… Mr. Barclay was best known for three things: popularizing American jazz in France in the postwar years; keeping the traditional French chanson alive into the age of rock ‘n’ roll; and presiding over parties so lavish that they were considered just the tiniest bit excessive even by the standards of the French Riviera….

Among the guests at some of his glittering parties… Jack Nicholson….”

“Joyce’s confidant in Zurich in 1918, Frank Budgen, luckily for us described the process of writing Ulysses…. ‘Not Bloom, not Stephen is here the principal personage, but Dublin itself… All towns are labyrinths…’  While working… Joyce bought a game called Labyrinth, which he played every evening for a time with his daughter, Lucia. From this game he cataloged the six main errors of judgment into which one might fall in seeking a way out of a maze.”

Beyond Geometry

(Title of current L. A. art exhibit)

John Baez:

What is the difference between topology and geometry?

Geometry you learn in high school; topology in college. So, topology costs more.

A bit more seriously….

is not ignorance —
  it is the illusion of knowledge.”

For the illusion of knowledge,
see (for instance)
The Importance of Being Nothingness,
by Craig J. Hogan
(American Scientist, Sept.-Oct. 2001).

A bit more seriously…

“These cases are
neither harmless nor amusing.”
