Study This Example, Part II

Filed under: Uncategorized — Tags: — m759 @ 11:06 AM

(Continued from 10:09 AM today)

The quotation below is from a webpage on media magnate
Walter Annenberg.

Annenberg Hall at Harvard, originally constructed to honor
the Civil War dead, was renamed in 1996 for his son Roger,
Harvard Class of ’62.

www.broadcastpioneers.com/
walterannenberg.html

“It was said that Roger was ‘moody and sullen’
spending large parts of his time reading poetry
and playing classical music piano. It had been
reported that Roger attempted suicide at the
age of eleven by slitting his wrists. He recovered
and was graduated Magna Cum Laude from
Episcopal Academy in our area. For awhile,
Roger attended Harvard, but he was removed
from the school’s rolls after Roger stopped doing
his school work and spent almost all his time
reading poetry in his room. He then was sent to
an exclusive and expensive treatment center
in Bucks County, Pennsylvania. At that facility,
Roger became more remote. It was said that he
often didn’t recognize or acknowledge his father.
On August 7, 1962, Roger Annenberg died from
an overdose of sleeping pills.”

A more appropriate Annenberg memorial, an article
in The Atlantic  magazine on June 25, notes that…

“Among those who ended up losing their battles
with mental illness through suicide are
Virginia Woolf, Ernest Hemingway, Vincent van Gogh,
John Berryman, Hart Crane, Mark Rothko, Diane Arbus,
Anne Sexton, and Arshile Gorky.”

The authors of the following offer an introduction to symmetry
in quilt blocks.  They assume, perhaps rightly, that their audience
is intellectually impaired:

“A quilt block is made of 16 smaller squares.
Each small square consists of two triangles.”

Study this example of definition.
(It applies quite precisely to the sorts of square patterns
discussed in the 1976 monograph Diamond Theory , but
has little relevance for quilt blocks in general.)

Die Scheinung des Wesens

Filed under: Uncategorized — Tags: , — m759 @ 4:00 AM

… und Nachtformen des Urgrundes

From George , by Friedrich Gundolf (Berlin, Bondi, 1920):

Wenn das Schlußgedicht des Teppichs "Der Schleier"
das ganze gestaltige "Leben" des Dichters als
einen Traum-nu des Geistes zeigt so ist damit
der Geistestag vollbracht und der Geist selbst
der dies vermag ist am Ende seiner Herrschaft
er steht vor dem Urgrund der ihn bewegt:
er erkennt sich selbst wenn nicht als Stoff
so doch als Kraft zu träumen. Die kosmische Nacht
in die er blickt ist zugleich Widerspiel des Gestaltenreiches
das er als Geist der Erde verwirk licht
und Widerspiel des Gesetzes das er als Geist des Lebens
verewigt kurz sie ist Traum und Tod "Traum"
nicht als die Fülle der Gesichte sondern als "Maja"
die Scheinung des Wesens vermöge
deren der Urgrund sich der Bindung im Raum immer wieder entzieht
wie er im Tod der Bindung durch die Zeit entgeht.
Traum ist die Aufhebung des Raum-Ichs,
Tod die Aufhebung des Zeit-Ichs— beides sind
Nachtformen des Urgrundes
die raumschaffende und -vernichtende Bewegung und
das zeitschaffende und -vernichtende Sein.

Dream Palace

Or: Mathematics and Narrative, Continued

In memory of a Stanford Arabist who reportedly died yesterday:

From preface to Ajami's 'The Dream Palace of the Arabs'

Another dream palace, from science fiction:

From Catherine Asaro’s  The Spacetime Pool :

She couldn’t believe him. That he sounded sane made none of this more plausible. “And you have no idea how this gate works?” she challenged.

His gaze flashed. “Of course I do. It’s a branch. From here to your mountains.”

“A tree, you mean?”

“No. A branch cut to another page. Your universe is one sheet, mine is another.”

She gaped at him. “Do you mean a Riemann sheet?  A branch cut from one Riemann sheet to another?”

“That’s right.” He hesitated. “You know these words?”

She laughed unsteadily. “It’s nonsense. Not the sheets, I mean, but they’re just mathematical constructs! They don’t actually exist. You can’t physically go through  a branch cut any more than you could step into a square root sign.”

He was watching her with an expression that mirrored how she had felt when he told her about his prophecy. “I have no idea what you’re talking about.”

“Complex variable analysis.” She felt as if she were in a play where she only knew part of the script. “A branch cut is like a slit in a sheet of paper. It opens onto another sheet. I suppose you could say the sheets are alternate universes. But they aren’t real.”

“They seem quite real,” he said.

Anyone tackling the Raumproblem  described here
on Feb. 21, 2014 should know the history of coordinatizations
of the 4×6 Miracle Octad Generator (MOG) array by R. T. Curtis
and J. H. Conway. Some documentation:

The above two images seem to contradict a statement by R. T. Curtis
in a 1989 paper.  Curtis seemed in that paper to be saying, falsely, that
his original 1973 and 1976 MOG coordinates were those in array M below—

This seemingly false statement involved John H. Conway's supposedly
definitive and natural canonical coordinatization of the 4×6 MOG
array by the symbols for the 24 points of the projective line over GF(23)—
{∞, 0, 1, 2, 3… , 21, 22}:

An explanation of the apparent falsity in Curtis's 1989 paper:

By "two versions of the MOG" Curtis seems to have meant merely that the
octads , and not the projective-line coordinates , in his earlier papers were
mirror images of the octads  that resulted later from the Conway coordinates,
as in the images below.

Some background on the large Desargues configuration

“The relevance of a geometric theorem is determined by what the theorem
tells us about space, and not by the eventual difficulty of the proof.”

— Gian-Carlo Rota discussing the theorem of Desargues

What space  tells us about the theorem :  

In the simplest case of a projective space  (as opposed to a plane ),
there are 15 points and 35 lines: 15 Göpel  lines and 20 Rosenhain  lines.*
The theorem of Desargues in this simplest case is essentially a symmetry
within the set of 20 Rosenhain lines. The symmetry, a reflection
about the main diagonal in the square model of this space, interchanges
10 horizontally oriented (row-based) lines with 10 corresponding
vertically oriented (column-based) lines.

Vide  Classical Geometry in Light of Galois Geometry.

* Update of June 9: For a more traditional nomenclature, see (for instance)
R. Shaw, 1995.  The “simplest case” link above was added to point out that
the two types of lines named are derived from a natural symplectic polarity 
in the space. The square model of the space, apparently first described in
notes written in October and December, 1978, makes this polarity clearly visible:

Twisty Quaternion Symmetry

Filed under: Uncategorized — m759 @ 9:11 PM

The previous post told how user58512 at math.stackexchange.com
sought in 2013 a geometric representation of Q, the quaternion group.
He ended up displaying an illustration that very possibly was drawn,
without any acknowledgement of its source, from my own work.

On the date that user58512 published that illustration, he further
pursued his March 1, 2013, goal of a “twisty” quaternion model.

On March 12, 2013,  he suggested that the quaternion group might be
the symmetry group of the following twisty-cube coloring:

IMAGE- Twisty-cube coloring illustrated by Jim Belk

Illustration by Jim Belk

Here is part of a reply by Jim Belk from Nov. 11, 2013, elaborating on
that suggestion:

IMAGE- Jim Belk's proposed GAP construction of a 2x2x2 twisty-cube model of the quaternion group 

Belk argues that the colored cube is preserved under the group
of actions he describes. It is, however, also preserved under a
larger group.  (Consider, say, rotation of the entire cube by 180
degrees about the center of any one of its checkered faces.)  The
group Belk describes seems therefore to be a  symmetry group,
not the  symmetry group, of the colored cube.

I do not know if any combination puzzle has a coloring with
precisely  the quaternion group as its symmetry group.

(Updated at 12:15 AM June 6 to point out the larger symmetry group
and delete a comment about an arXiv paper on quaternion group models.)

“In addition to Pearl, Bob’s other cousin, Bill Bailey,
