For C. S. Lewis, who was born on this date in 1898,
and Natalie Wood, who died on this date in 1981

"He was accustomed to receiving manuscripts from strangers…."

"Whoever you are— I have always depended on
the kindness of strangers." — A Streetcar Named Desire

From this journal on September 24, 2012

"A single self-transcendence" — Aldous Huxley

From an anonymous author at the website Kill Devil Hill

"This little story… has that climactic moment of 
heightened awareness…. This is a moment where
two individuals become one, empowering them
to transcend the limitations of their own individual
frailty and society. It's an epiphany, an almost
divine spark. It is an experience when one plus one
don't equal two, but something far greater."

Kill Devil Hills also appears in a 1983 film—

"Suppose it were possible to transfer
from one mind to another
the experience of another person."

Lines of Symbols

Filed under: Uncategorized — m759 @ 3:00 PM

C. P. Snow on G. H. Hardy, in Snow's foreword to A Mathematician's Apology

"One morning early in 1913, he found, among the letters on his breakfast table, a large untidy envelope decorated with Indian stamps. When he opened it, he found sheets of paper by no means fresh, on which, in a non-English holograph, were line after line of symbols. Hardy glanced at them without enthusiasm. He was by this time, at the age of thirty-six, a world famous mathematician: and world famous mathematicians, he had already discovered, are unusually exposed to cranks. He was accustomed to receiving manuscripts from strangers, proving the prophetic wisdom of the Great Pyramid, the revelations of the Elders of Zion, or the cryptograms that Bacon has inserted in the plays of the so-called Shakespeare."

Synesis

Filed under: Uncategorized — Tags: , — m759 @ 2:00 PM

From a New York Times  weblog last night—

The Reconstruction of Rome
By ROBERT BEASER

The New York Times , Nov. 27, 2012, 9:00 PM

Logic Pro software enables us to layer complex
technolike tracks and simulate meta, sampled orchestras—
fake orchestras that have on more than one occasion
fooled a jury of the most discriminating composers
into thinking it was the real thing. …

Several decades of cultural relativism has helped to
hasten the decline of the dominance of Western canon….

This next generation is becoming adept at taking small
bits of information, unformed, and assembling it
into larger asynchronous maps, of nonlinear order. 

IT from BITS*

These failures of number agreement—
orchestras… it,  decades… has,  bits… it —
suggest a look at synesis.

Synesis is a traditional grammatical/rhetorical term
derived from Greek σύνεσις (originally meaning "unification,
meeting, sense, conscience, insight, realization, mind, reason").
A constructio kata synesin  (or constructio ad sensum  in Latin)
means a grammatical construction in which a word takes
the gender or number not of the word with which it should
regularly agree, but of some other word implied in that word.
It is effectively an agreement of words with the sense,
instead of the morphosyntactic form. Example:
"If the band are popular, they will play next month." —Wikipedia

The conclusion of Wikipedia's synesis article is of particular interest:

Raiders of the Lost Lottery

Today's midday New York Lottery: 444 and 5222.

See Deuteronomy  4:44 and 5:2-22.

Counterexample

Filed under: Uncategorized — m759 @ 12:25 PM

The non-Coxeter simple reflection group of order 168
is a counterexample to the statement that
"Every finite reflection group is a Coxeter group."

The counterexample is based on a definition of "reflection group"
that includes reflections defined over finite fields.

Today I came across a 1911 paper that discusses the counterexample.
Of course, Coxeter groups were undefined in 1911, but the paper, by
Howard H. Mitchell, discusses the simple order-168 group as a reflection group .

A review of this topic might be appropriate for Jessica Fintzen's 2012 fall tutorial at Harvard
on reflection groups and Coxeter groups. The syllabus for the tutorial states that
"finite Coxeter groups correspond precisely to finite reflection groups." This statement
is based on Fintzen's definition of "reflection group"—

"Reflection groups are— as their name indicates—
groups generated by reflections across
hyperplanes of Rn which contain the origin."

For some background, see William Kantor's 1981 paper "Generation of Linear Groups"
(quoted at the finitegeometry.org page on the simple order-168 counterexample).
Kantor discusses Mitchell's work in some detail, but does not mention the
simple order-168 group explicitly.

Representation

Filed under: Uncategorized — m759 @ 10:31 AM

The title of yesterday's post Will and Representation is of course
a reference to Schopenhauer's philosophical work of that name.

As the post itself indicates, the title is also a punning reference to
mathematical representation theory . 

To avoid confusion, it should be noted that Schopenhauer's
representation , in the original German, was Vorstellung .

The German for mathematical  representation theory is,
on the other hand, Darstellungstheorie . (The mathematical
use of Vorstellung  is non-technical, referring to concepts
of pedagogy. (A group presentation  is a Präsentation .))

Will and Representation*

Filed under: Uncategorized — m759 @ 2:56 PM

Robert A. Wilson, in an inaugural lecture in April 2008—

Representation theory

A group always arises in nature as the symmetry group of some object, and group
theory in large part consists of studying in detail the symmetry group of some
object, in order to throw light on the structure of the object itself (which in some
sense is the “real” object of study).

But if you look carefully at how groups are used in other areas such as physics
and chemistry, you will see that the real power of the method comes from turning
the whole procedure round: instead of starting from an object and abstracting
its group of symmetries, we start from a group and ask for all possible objects
that it can be the symmetry group of 
.

This is essentially what we call Representation theory . We think of it as taking a
group, and representing it concretely in terms of a symmetrical object.

Now imagine what you can do if you combine the two processes: we start with a
symmetrical object, and find its group of symmetries. We now look this group up
in a work of reference, such as our big red book (The ATLAS of Finite Groups),
and find out about all (well, perhaps not all) other objects that have the same
group as their group of symmetries.

We now have lots of objects all looking completely different, but all with the same
symmetry group. By translating from the first object to the group, and then to
the second object, we can use everything we know about the first object to tell
us things about the second, and vice versa.

As Poincaré said,

Mathematicians do not study objects, but relations between objects.
Thus they are free to replace some objects by others, so long as the
relations remain unchanged.

and partitions of the latter as points of the former:

Finite Relativity

(Continued from 1986)

S. H. Cullinane
The relativity problem in finite geometry.
Feb. 20, 1986.

This is the relativity problem: to fix objectively a class of equivalent coordinatizations and to ascertain the group of transformations S mediating between them.

— H. Weyl, The Classical Groups ,
Princeton Univ. Pr., 1946, p. 16

In finite geometry "points" are often defined as ordered n-tuples of a finite (i.e., Galois) field GF(q). What geometric structures ("frames of reference," in Weyl's terms) are coordinatized by such n-tuples? Weyl's use of "objectively" seems to mean that such structures should have certain objective— i.e., purely geometric— properties invariant under each S.

This note suggests such a frame of reference for the affine 4-space over GF(2), and a class of 322,560 equivalent coordinatizations of the frame.

The frame: A 4×4 array.

The invariant structure:

The following set of 15 partitions of the frame into two 8-sets.

occurred to me.  I chose the name It intuitively,
because an IT does not have a heart or soul. 
And I did not understand consciously
at the time of writing that the intellect,
when it is not informed by the heart, is evil."

"Any sufficiently advanced technology is indistinguishable from magic."

"The HP/Autonomy  Debacle," by John C. Dvorak at pcmag.com on Tuesday, Nov. 20, 2012—

"The whole Autonomy  thing was weird since the company seemed to be performing magic. On co-founder Michael Richard Lynch's Wikipedia page, the company is described as 'a leader in the area of computer understanding of unstructured information, an area which is becoming known as meaning-based computing .'

I do not know how gullible HP's board of directors is, but when I see the sudden emergence of something called 'meaning-based computing,' the alarms sound and the bullcrap meter begins to tag the red line."

A story by Terence K. Huwe in Online  magazine, Sept.-Oct. 2011, defines meaning-based computing (MBC), discusses Autonomy , and llnks to…

John Markoff in The New York Times , March 4, 2011— 

"Engineers and linguists at Cataphora, an information-sifting company based in Silicon Valley, have their software mine documents for the activities and interactions of people— who did what when, and who talks to whom. The software seeks to visualize chains of events. It identifies discussions that might have taken place across e-mail, instant messages and telephone calls.

Then the computer pounces, so to speak, capturing 'digital anomalies' that white-collar criminals often create in trying to hide their activities.

For example, it finds 'call me' moments— those incidents when an employee decides to hide a particular action by having a private conversation. This usually involves switching media, perhaps from an e-mail conversation to instant messaging, telephone or even a face-to-face encounter."

Resisting the Bogus

Filed under: Uncategorized — m759 @ 12:00 PM

From remarks by Wallace Stevens featured in recent Log24 posts:

"The poet finds that as between these two sources: the imagination and reality, the imagination is false, whatever else may be said of it, and reality is true; and being concerned that poetry should be a thing of vital and virile importance, he commits himself to reality, which then becomes his inescapable and ever-present difficulty and innamorata. In any event, he has lost nothing; for the imagination, while it might have led him to purities beyond definition, never yet progressed except by particulars. Having gained the world, the imaginative remains available to him in respect to all the particulars of the world. Instead of having lost anything, he has gained a sense of direction and a certainty of understanding. He has strengthened himself to resist the bogus."

The Particulars of Language

Filed under: Uncategorized — Tags: — m759 @ 11:01 AM

This post is in memory of an English church musician whose
death was noted here yesterday evening in a post titled
"The Particulars of Rapture," a phrase from Wallace Stevens.

Sir Philip Ledger, who died on Sunday, was a
"church musician who produced magical settings
of carols," according to The Telegraph  RSS feed.

It is not clear what the Telegraph  meant by "magical settings."

Perhaps the phrase "his settings of carols" in his obituary refers
to the annual service of Nine Lessons and Carols at Cambridge,
where he was for a time director of music at King's College.

If so, the settings would be the Lessons, readings from the Bible
(a "ledger," in the sense defined below).  Such readings should
not be confused with notions from the world of Harry Potter. 

Examples: The Lessons from last Christmas in Cambridge.

Poetry and Truth

From today's noon post

"In all his poems with all their enchantments
for the poet himself, there is the final enchantment
that they are true. The significance of the poetic act
then is that it is evidence. It is instance and illustration.
It is an illumination of a surface,
the movement of a self in the rock.
Above all it is a new engagement with life.
It is that miracle to which the true faith of the poet
attaches itself."

— Wallace Stevens at Bard College, March 30, 1951

Stevens also said at Bard that

"When Joan of Arc said: 

Have no fear: what I do, I do by command.
My brothers of Paradise tell me what I have to do.

these words were the words of an hallucination.
No matter what her brothers of Paradise drove her to do,
what she did was never a poetic act of faith in reality
because it could not be."

There are those who would dispute this.

"In one of the first lines uttered by Daniel Day-Lewis, playing Abraham Lincoln in the new Steven Spielberg film opening Nov. 9, he says, 'I could be bounded in a nutshell, and count myself a king of infinite space— were it not that I have bad dreams.'

The line was ripped straight from 'Hamlet,' by Lincoln's favorite writer, William Shakespeare. Tony Kushner, the Pulitzer Prize-winning playwright ('Angels in America') who wrote the script for the film, says that Shakespeare, much like Lincoln, 'had extraordinary mastery over the darkest parts of the human spirit.'"

The above quotation omits Shakespeare's words prefacing the nutshell part— "O God."

Group Actions

Filed under: Uncategorized — m759 @ 4:30 PM

The December 2012 Notices of the American
Mathematical Society  
has an ad on page 1564
(in a review of two books on vulgarized mathematics)
for three workshops next year on "Low-dimensional
Topology, Geometry, and Dynamics"—

(Only the top part of the ad is shown; for further details
see an ICERM page.)

(ICERM stands for Institute for Computational
and Experimental Research in Mathematics.)

The ICERM logo displays seven subcubes of
a 2x2x2 eight-cube array with one cube missing—

The logo, apparently a stylized image of the architecture 
of the Providence building housing ICERM, is not unlike
a picture of Froebel's Third Gift—

 

Froebel's third gift, the eightfold cube

© 2005 The Institute for Figuring

Photo by Norman Brosterman fom the Inventing Kindergarten
exhibit at The Institute for Figuring (co-founded by Margaret Wertheim)

The eighth cube, missing in the ICERM logo and detached in the
Froebel Cubes photo, may be regarded as representing the origin
(0,0,0) in a coordinatized version of the 2x2x2 array—
in other words the cube invariant under linear , as opposed to
more general affine , permutations of the cubes in the array.

These cubes are not without relevance to the workshops' topics—
low-dimensional exotic geometric structures, group theory, and dynamics.

See The Eightfold Cube, A Simple Reflection Group of Order 168, and 
The Quaternion Group Acting on an Eightfold Cube.

Those who insist on vulgarizing their mathematics may regard linear
and affine group actions on the eight cubes as the dance of
Snow White (representing (0,0,0)) and the Seven Dwarfs—

Descartes Field of Dreams

Filed under: Uncategorized — m759 @ 2:01 PM

(A prequel to Galois Field of Dreams)

The opening of Descartes' Dream ,
by Philip J. Davis and Reuben Hersh—

"The modern world,
our world of triumphant rationality,
began on November 10, 1619,
with a revelation and a nightmare."

For a revelation, see Battlefield Geometry.

For a nightmare, see Joyce's Nightmare.

Some later work of Descartes—

From "What Descartes knew of mathematics in 1628,"
by David Rabouin, CNRS-Univ. Paris Diderot,
Historia Mathematica , Volume 37, Issue 3,
Contexts, emergence and issues of Cartesian geometry,
August 2010, pages 428–459 —

Fig. 5. How to represent the difference between white, blue, and red
according to Rule XII [from Descartes, 1701, p. 34].

A translation —

The 4×4 array of Descartes appears also in the Battlefield Geometry posts.
For its relevance to Galois's  field of dreams, see (for instance) block designs.

Theory

Filed under: Uncategorized — Tags: — m759 @ 11:01 AM

Sean French, in a March 1998 New Statesman
review of a book on Wittgenstein and Hitler,
discusses the author's theory that …

"… the Jew who played the decisive role
in inspiring the Holocaust also played
the decisive role in bringing it to an end.

There is something heroic about this argument
and it would be a good subject for a novel about
the dangers of creating theories out of nothing.
Nabokov should have written it. It is not just
that there are weak links in the theory. There are
no links in the theory."

"Nabokov should have written it."… See Bend Sinister.

For Leonard Cohen Fans

Filed under: Uncategorized — m759 @ 9:00 AM

Leading this morning's online New York Times  
obituaries list is one for a leftist Episcopal priest.

That obituary contains a link to a 1996 Times  story — 

Old Friends, New Foes:
President and a Preacher;
One 60's Activist Runs Columbia;
One Fights It

A check for background on the Columbia president
in that story yields the following from a leftist journalist's
website in a 2012 post dated October 26 (date of the
1917 October Revolution in Russia)—

Click for further details of this leftist allegation, which is
clearly false (because based on a ludicrously bad
misreading of a Rice University puff piece), and would
be libelous if its target were alive.

See a Rice University obituary for the "Nazi spy"
in question, who died on May 25, 2010. (See also
 this journal on that date.)

The same leftist webpage contains a link to another leftist's
attack on a respected charitable organization that may
or may not have, or have had, CIA connections—

The International Rescue Committee (IRC).

In the spirit of Leonard Cohen's "then we take Berlin" lyric,
here is a note on how the IRC logo

might be rendered in a way that is, though less visually appealing,
more logical— i.e., more purely an example of Bauhaus style—

This morning's New York Times  obituaries—

These suggest a look at Solving Nabokov's Lolita Riddle ,

That book discusses Lolita as a character like Lewis Carroll's Alice.

(The Red Queen and Alice of course correspond to figures in
the first two thumbnails above.)

From the obituary associated with the third thumbnail above:

"Front-page headlines combined concision and dark humor." 

The title of this post, Bend Sinister , is not unlike such a headline.
It is the title of a novel by Nabokov (often compared with Orwell's 1984 )
that is discussed in the Lolita Riddle  book.

A Very High Order

From a Washington Post  book review of
The Essays of Leonard Michaels
by Jonathan Yardley, Sunday, July 26, 2009—

"Michaels said that his literary influences included Franz Kafka, Lord Byron and Wallace Stevens (this last is frequently quoted in these essays), but reading that paragraph one can't help thinking that as a young man in the 1950s he must have spent a lot of time listening to Mort Sahl, Lenny Bruce and the other great Jewish comedians of the day, as his own comic voice and timing bear more than passing resemblance to theirs. In another essay, 'A Sentimental Memoir,' he recalls being 'saved' as a young man by a professor of English at the University of Michigan named Austin Warren, and then he meanders into an account of falling 'insanely in love' (which seems to have been a strong predilection with him) with a girl in Warren's class:

'The girl had a slender boyish figure and blondish hair. I thought nobody but me considered her striking or had noticed the subtle perfection of her beautiful face. When I told my friend Julian that the most beautiful girl in Michigan was in Warren's class, he named her. He told me that she modeled naked for art students, she had a horrible reputation for licentiousness, everybody knew who she was, and that he was in love with her too. I decided that I was ready to forgive her everything. To forgive a girl was a very popular sentiment of the day. There were plays, novels, and movies about forgiving bad girls. As for the girl I was ready to forgive, I now suppose there were a couple of hundred other men who were forgiving her at the same time, all of us subject to a sort of spiritual narcissism that has long since gone out of the world. Too bad, I think, since it had extraordinary intensity and made a man feel tortured by goodness, which is a very high order of feeling.' "

'the post-rigorous,' in which intuition suddenly starts to play a part."
