"The (83, 83) Möbius-Kantor configuration here described by Coxeter is of course part of the larger (94, 123) Hesse configuration. Simply add the center point of the 3×3 Galois affine plane and the four lines (1 horizontal, 1 vertical, 2 diagonal) through the center point." An illustration—

A Many-Sided Theory

Filed under: Uncategorized — m759 @ 5:48 PM

On this date 106 years ago…

Prefatory note from Hudson's classic Kummer's Quartic Surface ,
Cambridge University Press, 1905—

RONALD WILLIAM HENRY TURNBULL HUDSON would have
been twenty-nine years old in July of this year; educated at
St Paul's School, London, and at St John's College, Cambridge,
he obtained the highest honours in the public examinations of the
University, in 1898, 1899, 1900; was elected a Fellow of St John's
College in 1900; became a Lecturer in Mathematics at University
College, Liverpool, in 1902; was D.Sc. in the University of London
in 1903; and died, as the result of a fall while climbing in Wales,
in the early autumn of 1904….

A many-sided theory such as that of this volume is
generally to be won only by the work of many lives;
one who held so firmly the faith that the time is well spent
could ill be spared.

— H. F. Baker, 27 March 1905

For some more recent remarks related to the theory, see
Defining Configurations and its updates, March 20-27, 2011.

Crazy Arms
Ray Price
Chart position: No. 1, 1956
(written by Ralph E. Mooney)

Now blue ain't the word for the way that I feel
And a storm is brewing in this heart of mine
This ain't no crazy dream I know that it's real
You're someone else's love now, you're not mine

Crazy arms that reach to hold somebody new
But my yearning heart keeps saying you're not mine
My troubled mind knows soon to another you'll be wed
That's why I'm lonely all the time

Please take these treasured dreams I had for you and me
And take all the love I thought was mine
Someday my crazy arms will hold somebody new
But right now I'm so lonesome I could die

Crazy arms that reach to hold somebody new
But my yearning heart keeps saying you're not mine
My troubled mind knows soon to another you'll be wed
You're someone else's love now, you're not mine
Well you're someone else's love now, you're not mine

Combinatorial Delight

Filed under: Uncategorized — m759 @ 12:00 PM

See Margaret Atwood in this journal.

This link was suggested by the phrase "combinatorial* delight" in last night's quote from Nabokov, which also appears in Douglas Glover's review essay, "Her Life Entire," in Books in Canada , Volume 17, Number 7, October 1988—

Cat's Eye  is Atwood's seventh novel. It is dense, intricate, and superb, as thematically diverse and complex as anything she has written. It is what you might expect from a writer at mid-career, mid-life: a portrait of the artist, a summation of what she knows about art and people. It is also an Atwoodian Under the Volcano , a vision of Toronto as Hell.

See also Under the Volcano  and Toronto in this journal.

Existence, or at least a minute part

So does the verse of galaxies divine
Which I suspect is an iambic line.
I'm reasonably sure that we survive
And that my darling somewhere is alive…."

Defining Configurations*

Filed under: Uncategorized — m759 @ 7:00 PM

The On-Line Encyclopedia of Integer Sequences has an article titled "Number of combinatorial configurations of type (n_3)," by N.J.A. Sloane and D. Glynn.

From that article:

  • DEFINITION: A combinatorial configuration of type (n_3) consists of an (abstract) set of n points together with a set of n triples of points, called lines, such that each point belongs to 3 lines and each line contains 3 points.
  • EXAMPLE: The unique (8_3) configuration consists of the triples 125, 148, 167, 236, 278, 347, 358, 456.

The following corrects the word "unique" in the example.

http://www.log24.com/log/pix11/110320-MoebiusKantorConfig500w.jpg

* This post corrects an earlier post, also numbered 14660 and dated 7 PM March 18, 2011, that was in error.
   The correction was made at about 11:50 AM on March 20, 2011.

_____________________________________________________________

Update of March 21

The problem here is of course with the definition. Sloane and Glynn failed to include in their definition a condition that is common in other definitions of configurations, even abstract or purely "combinatorial" configurations. See, for instance, Configurations of Points and Lines , by Branko Grunbaum (American Mathematical Society, 2009), p. 17—

In the most general sense we shall consider combinatorial (or abstract) configurations; we shall use the term set-configurations as well. In this setting "points" are interpreted as any symbols (usually letters or integers), and "lines" are families of such symbols; "incidence" means that a "point" is an element of a "line". It follows that combinatorial configurations are special kinds of general incidence structures. Occasionally, in order to simplify and clarify the language, for "points" we shall use the term marks, and for "lines" we shall use blocks. The main property of geometric configurations that is preserved in the generalization to set-configurations (and that characterizes such configurations) is that two marks are incident with at most one block, and two blocks with at most one mark.

Whether or not omitting this "at most one" condition from the definition is aesthetically the best choice, it dramatically changes the number  of configurations in the resulting theory, as the above (8_3) examples show.

Update of March 22 (itself updated on March 25)

For further background on configurations, see Dolgachev—

http://www.log24.com/log/pix11/110322-DolgachevIntro.gif

Note that the two examples Dolgachev mentions here, with 16 points and 9 points, are not unrelated to the geometry of 4×4 and 3×3 square arrays. For the Kummer and related 16-point configurations, see section 10.3, "The Three Biplanes of Order 4," in Burkard Polster's A Geometrical Picture Book  (Springer, 1998). See also the 4×4 array described by Gordon Royle in an undated web page and in 1980 by Assmus and Sardi. For the Hesse configuration, see (for instance) the passage from Coxeter quoted in Quaternions in an Affine Galois Plane.

Update of March 27

See the above link to the (16,6) 4×4 array and the (16,6) exercises using this array in R.D. Carmichael's classic Introduction to the Theory of Groups of Finite Order  (1937), pp. 42-43. For a connection of this sort of 4×4 geometry to the geometry of the diamond theorem, read "The 2-subsets of a 6-set are the points of a PG(3,2)" (a note from 1986) in light of R.W.H.T. Hudson's 1905 classic Kummer's Quartic Surface , pages 8-9, 16-17, 44-45, 76-77, 78-79, and 80.

Time Travel Poem

Filed under: Uncategorized — m759 @ 7:11 PM

From "This Week's Hype II," a post at Peter Woit's physics weblog this afternoon, a comment—

TedUnger says:
March 17, 2011 at 5:34 pm

"… there’s been nothing from these CERN scientists
except some lousy boring data on physics!
They better at least give us some time travel or else!

You know that is what Joe Public is thinking."

The commenter's identity is not clear. Even less clear is the identity of his subject, Joe Public.

For some remarks on time travel from literature rather than science, see "Damnation Morning" in this journal.

Erin O'Connor's St. Patrick's Day post this morning says,

"[Roddy] Doyle’s take on the Irish struggle for independence,
A Star Called Henry , has a lovely touch of magical realism."

Note that the remarks by Henry Baker in this morning's post here  were dated Thursday, 11 September 1913.

Related material—

Yet they were of a different kind
The names that stilled your childish play,
They have gone about the world like wind,
But little time had they to pray
For whom the hangman’s rope was spun,
And what, God help us, could they save:
Romantic Ireland’s dead and gone,
It’s with O’Leary in the grave.

William Butler Yeats, "September 1913"

Remarks on Reality

Filed under: Uncategorized — m759 @ 9:12 AM

Conclusion of "The Place of Pure Mathematics" —

"Dogmas and philosophies, it would seem, rise and fall. But gradually accumulating throughout the ages, from the earliest dawn of history, there is a body of doctrine, a reasoned insight into the relations of exact ideas, painfully won and often tested. And this remains the main heritage of man; his little beacon of light amidst the solitudes and darknesses of infinite space; or, if you prefer, like the shout of children at play together in the cultivated valleys, which continues from generation to generation.

Yes, and continues for ever! A universe which has the potentiality of becoming thus conscious of itself is not without something of which that which we call memory is but an image. Somewhere, somehow, in ways we dream not of, when you and I have merged again into the illimitable whole, when all that is material has ceased, the faculty in which we now have some share, shall surely endure; the conceptions we now dimly struggle to grasp, the joy we have in the effort, these are but part of a greater whole. Some may fear, and some may hope, that they and theirs shall not endure for ever. But he must have studied Nature in vain who does not see that our spiritual activities are inherent in the mighty process of which we are part; who can doubt of their persistence.

And, on the intellectual side, of all that is best ascertained, and surest, and most definite, of these; of all that is oldest and most universal; of all that is most fundamental and far-reaching, of these activities, Pure Mathematics is the symbol and the sum."

— From a 1913 address by geometry saint Henry Frederick Baker, who died on this date in 1956

The feast of another saint, Patrick, also falls on 3/17.  The date itself is related, if only by chance, to the following remark—

“317 is a prime, not because we think so,
or because our minds are shaped in one way
rather than another, but because it is so,
because mathematical reality is built that way.”

— From a 1940 book by the somewhat less saintly number theorist G. H. Hardy

In the Texas oil town where I grew up, fierceness won fights, but I was thin-skinned— an unfashionably bookish kid whose brain wattage was sapped by a consuming inner life others didn’t seem to bear the burden of. I just seemed to have more frames per second than other kids."

This post was prompted by two remarks…

    The Accidental Mathematician— "The Girl Who Played with Fermat's Theorem."

"The worst thing about the series is the mathematical interludes in The Girl Who Played With Fire….

Salander is fascinated by a theorem on perfect numbers—
one can verify it for as many numbers as one wishes, and it never fails!—
and then advances through 'Archimedes, Newton, Martin Gardner,*
and a dozen other classical mathematicians,' all the way to Fermat’s last theorem."

2.  "The fact that the pattern retains its symmetry when you permute the rows and columns
     is very well known to combinatorial theorists who work with matrices."
     [My italics; note resemblance to the Brualdi-Ryser title above.]

     –Martin Gardner in 1976 on the diamond theorem

* Compare Eric Temple Bell (as quoted at the MacTutor history of mathematics site)—

    "Archimedes, Newton, and Gauss, these three, are in a class by themselves
     among the great mathematicians, and it is not for ordinary mortals
     to attempt to range them in order of merit."

     This is from the chapter on Gauss in Men of Mathematics .

A Latin square  of order n  is a n × n  array with entries from the symbol set {1, 2, …, n }, such that each symbol occurs once in each row and once in each column. Now it is not hard to show that, up to permutations of the rows, columns and symbols, there are only two Latin squares of order 4:

1 2 3 4
2 1 4 3
3 4 1 2

Paradigms Lost

Filed under: Uncategorized — Tags: — m759 @ 5:48 PM

(Continued from February 19)

The cover of the April 1, 1970 second edition of The Structure of Scientific Revolutions , by Thomas S. Kuhn—

IMAGE- A Galois cube: model of the 27-point affine 3-space

If Galois geometry is thought of as a paradigm shift from Euclidean geometry,
both images above— the Kuhn cover and the nine-point affine plane—
may be viewed, taken together, as illustrating the shift. The nine subcubes
of the Euclidean  3×3 cube on the Kuhn cover do not  form an affine plane
in the coordinate system of the Galois  cube in the second image, but they
at least suggest  such a plane. Similarly, transformations of a
non-mathematical object, the 1974 Rubik  cube, are not Galois  transformations,
but they at least suggest  such transformations.

not unrelated to the problems of commensurability  discussed by Kuhn.

Ash Wednesday Surprise

Filed under: Uncategorized — m759 @ 11:07 AM

IMAGE- Errol Morris- 'The Ashtray'- at The New York Times

 Part 3 of 5  (See also Part 1 and Part 2) begins as follows…

"Incommensurable. It is a strange word. I wondered, why  did Kuhn choose it? What was the attraction? 

Here’s one clue. At the very end of 'The Road Since Structure,' a compendium of essays on Kuhn’s work, there is an interview with three Greek philosophers of science, Aristides Baltas, Kostas Gavroglu and Vassiliki Kindi. Kuhn provides a brief account of the historical origins of his idea. Here is the relevant segment of the interview.

T. KUHN: Look, 'incommensurability' is easy.

V. KINDI: You mean in mathematics?

T. KUHN: …When I was a bright high school mathematician and beginning to learn Calculus, somebody gave me—or maybe I asked for it because I’d heard about it—there was sort of a big two-volume Calculus book by, I can’t remember whom. And then I never really read it. I read the early parts of it. And early on it gives the proof of the irrationality of the square root of 2. And I thought it was beautiful. That was terribly exciting, and I learned what incommensurability was then and there. So, it was all ready for me, I mean, it was a metaphor but it got at nicely what I was after. So, that’s where I got it.

'It was all ready for me.' I thought, 'Wow.' The language was suggestive. I imagined √2 provocatively dressed, its lips rouged. But there was an unexpected surprise. The idea didn’t come from the physical sciences or philosophy or linguistics, but from mathematics ."

A footnote from Morris (no. 29)—

"Those who are familiar with the proof [of irrationality] certainly don’t want me to explain it here; likewise, those who are unfamiliar with it don’t want me to explain it here, either. There are many simple proofs in many histories of mathematics — E.T. Bell, Sir Thomas Heath, Morris Kline, etc., etc. Barry Mazur offers a proof in his book, 'Imagining Numbers (particularly the square root of minus fifteen),' New York, NY: Farrar, Straus and Giroux. 2003, 26ff. And there are two proofs in his essay, 'How Did Theaetetus Prove His Theorem?', available on Mazur’s Harvard Web site."

There may, actually, be a few who do  want the proof. They may consult the sources Morris gives, or the excellent  description by G.H. Hardy in A Mathematician's Apology , or, perhaps best of all for present purposes, the proof as described in a "sort of a big two-volume Calculus book" (perhaps the one Kuhn mentioned)…  See page 6 and page 7 of  Volume One  of Richard Courant's classic Differential and Integral Calculus  (second edition, 1937, reprinted many times through 1970, and again in a Wiley Classics Library Edition in 1988).

THE ULTIMATUM

I don’t want to die in
a language I can’t understand.
— Jorge Luis Borges

Comment 71

"I agree with one of the earlier commenters that this is a piece of fine literary work. And in response to some of those who have wondered 'WHAT IS THE POINT?!' of this essay, I would like to say: Must literature always answer that question for us (and as quickly and efficiently as possible)?"

For an excellent survey of the essay's historical context, see The Stanford Encyclopedia of Philosophy article

A search for some background on Dmitri Tymoczko, the subject of yesterday's evening entry on music theory, shows that his name and mine once both appeared in the same web page— "This Week's Finds in Mathematical Physics (Week 234)," by John Baez, June 12, 2006 (linked to by the Wikipedia article on transformational music theory).

In that page, Baez speculates on the possibility of a connection between music theory and Mathieu groups and says—

"For a pretty explanation of M24, also try this:

Steven H. Cullinane, Geometry of the 4 × 4 square, http://finitegeometry.org/sc/16/geometry.html."

I know of no connection* between the groups I discussed there and music theory. For some background on Tymoczko's work, see the helpful survey "Exploring Musical Space," by Julian Hook (Science  magazine, 7 July 2006).

* Apart, that is, from the tesseract (see Geometry of the 4 × 4 Square) shown by Tymoczko in a 2010 lecture

http://www.log24.com/log/pix11/110305-TymoczkoTesseract.jpg

This is perhaps "Chopin's tesseract" from section 8.5 of Tymoczko's new book

Susanne for Suzanne

From pages 7-8 of William York Tindall’s Literary Symbolism  (Columbia U. Press, 1955)—

                                     ... According to Cassirer's Essay 
on Man, as we have seen, art is a symbolic form, parallel in respect 
of this to religion or science. Each of these forms builds up a universe 
that enables man to interpret and organize his experience; and each 
is a discovery, because a creation, of reality. Although similar in func- 
tion, the forms differ in the kind of reality built. Whereas science
builds it of facts, art builds it of feelings, intuitions of quality, and 
the other distractions of our inner life— and in their degrees so do 
myth and religion. What art, myth, and religion are, Cassirer con- 
fesses, cannot be expressed by a logical definition. 

Nevertheless, let us see what Clive Bell says about art. He calls 
it "significant form," but what that is he is unable to say. Having 
no quarrel with art as form, we may, however, question its signifi- 
cance. By significant he cannot mean important in the sense of 
having import, nor can he mean having the function of a sign; 
for to him art, lacking reference to nature, is insignificant. Since, 
however, he tells us that a work of art "expresses" the emotion of 
its creator and "provokes" an emotion in its contemplator,he seems 
to imply that his significant means expressive and provocative. The 
emotion expressed and provoked is an "aesthetic emotion," contem- 
plative, detached from all concerns of utility and from all reference. 

Attempting to explain Bell's significant form, Roger Fry, equally 
devoted to Whistler and art for art's sake, says that Flaubert's "ex- 
pression of the idea" is as near as he can get to it, but neither Flaubert 
nor Fry tells what is meant by idea. To "evoke" it, however, the artist 
creates an "expressive design" or "symbolic form," by which the 
spirit "communicates its most secret and indefinable impulses." 

Susanne Langer,who occupies a place somewhere between Fry 
and Cassirer, though nearer the latter, once said in a seminar that a 
work of art is an "unassigned syntactical symbol." Since this defini- 

End of page 7 

tion does not appear in her latest book, she may have rejected it, but 
it seems far more precise than Fry's attempt. By unassigned she prob- 
ably intends insignificant in the sense of lacking sign value or fixed 
reference; syntactical implies a form composed of parts in relation- 
ship to one another; and a symbol, according to Feeling and Form, 
is "any device whereby we are enabled to make an abstraction." Too 
austere for my taste, this account of symbol seems to need elaboration, 
which, to be sure, her book provides. For the present, however, taking 
symbol to mean an outward device for presenting an inward state, 
and taking unassigned and syntactical as I think she uses them, let 
us tentatively admire her definition of the work of art.
