"Some 30 paces east of the spooky old Chateau Marmont is
the intersection of Selma and Sunset Boulevard." . . . . 
"Though it is not much of an intersection, the owner of
the liquor store on that corner might resent that you have
slotted his parking lot in the Twilight Zone. . . .
And directly across Sunset from Selma looking south is
where the infamous Garden of Allah used to stand. . . ."

To Forge a Head

Filed under: Uncategorized — m759 @ 12:25 PM

The title was suggested by a 2014 Vanity Fair  piece
by James Toback (Harvard '66).

"He squinted at this vision of a Qualityless world for a while,
conjured up more details, thought about it, and then squinted
some more and thought some more and then finally circled
back to where he was before.

Squareness.

That's the look. That sums it. Squareness. When you subtract
quality you get squareness. Absence of Quality is the essence
of squareness."

And when you add  quality?

The Source (Not by Michener)

Filed under: Uncategorized — m759 @ 11:18 AM
 

Wikipedia:  Taiji (philosophy)

Etymology

The word 太極 comes from I Ching : "易有太極,是生兩儀,兩儀生四象,四象生八卦,八卦定吉凶,吉凶生大業。"

Taiji  (太極) is a compound of tai   "great; grand; supreme; extreme; very; too" (a superlative variant of da   "big; large; great; very") and ji   "pole; roof ridge; highest/utmost point; extreme; earth's pole; reach the end; attain; exhaust". In analogy with the figurative meanings of English pole, Chinese ji  極 "ridgepole" can mean "geographical pole; direction" (e.g., siji  四極 "four corners of the earth; world's end"), "magnetic pole" (Beiji  北極 "North Pole" or yinji  陰極 "negative pole; cathode"), or "celestial pole" (baji  八極 "farthest points of the universe; remotest place"). Combining the two words, 太極 means "the source, the beginning of the world".

Common English translations of the cosmological Taiji  are the "Supreme Ultimate" (Le Blanc 1985, Zhang and Ryden 2002) or "Great Ultimate" (Chen 1989, Robinet 2008); but other versions are the "Supreme Pole" (Needham and Ronan 1978), "Great Absolute", or "Supreme Polarity" (Adler 1999).

Shift Lock key from manual typewriter, linking to Levin's 'The Philosopher's Gaze'

"As many philosophers have noted, in the German language,
the word Schein  bears three distinct meanings:

(i) shining, radiance, luminosity

(ii) manifesting, phenomenal appearing, showing itself, coming to light

(iii) illusion, deception, semblance, 'mere' appearance

In the Greek language of Plato's thought, the first two meanings were
bound together by their etymology. But Plato's metaphysics, drawing
a line of irreconcilable separation between the reality of a higher realm
of pure Ideas and the illusoriness of a lower realm consisting of sensuous
appearances, exhibits a logic that he saw connecting inextricably all three
of these seemingly unconnected meanings."

Design Grammar***

Filed under: Uncategorized — m759 @ 10:22 PM

The elementary shapes at the top of the figure below mirror
the looking-glass property  of the classical Lo Shu square.

The nine shapes at top left* and their looking-glass reflection
illustrate the looking-glass reflection relating two orthogonal
Latin squares over the three digits of modulo-three arithmetic.

Combining these two orthogonal Latin squares,** we have a
representation in base three of the numbers from 0 to 8.

Adding 1 to each of these numbers yields the Lo Shu square.

* The array at top left is from the cover of
Wonder Years:
Werkplaats Typografie 1998-2008

** A well-known construction.

*** For other instances of what might be
called "design grammar" in combinatorics,

Rosalind Krauss in 1978

"To get inside the systems of this work,
whether LeWitt's or Judd's or Morris's,
is precisely to enter
a world without a center,
a world of substitutions and transpositions
nowhere legitimated by the revelations
of a transcendental subject. This is the strength
of this work, its seriousness, and its claim to modernity." 

Wikipedia

"The center of
the quaternion group,
Q8 = {1, −1, i, −i, j, −j, k, −k} ,
is {1, −1}."

Smith College in 2011 on some music by Dan Brown's brother —

"Using the conventions of a traditional five-movement
Roman Catholic Mass to revere Darwin’s body of work,
Gregory Brown, Smith’s assistant director of choral
activities and a composer of choral music, is
collaborating with Craig Phillips, an early music specialist
and member of the classical a cappella male quartet
New York Polyphony, to create the piece Missa Charles Darwin . 
Brown is building the work in three large-scale sections and
scoring it for a male vocal quartet, which will be performed by
New York Polyphony."

https://www.smith.edu/insight/stories/darwin.php

Dan Brown has said his brother's Missa  helped suggest his new novel Origin .

Material from Smith College related to a performance of
Missa Charles Darwin  at the college on Feb. 4, 2011 —

Dan Brown, in the following passage, claims that an eight-ray star with arrowheads
at the rays' ends is "the mathematical symbol for entropy."  Brown may have first
encountered this symbol at a questionable "Sacred Science" website.  Wikipedia
discusses some even less  respectable uses of the symbol.

My own version of the above symbol (from the pure mathematics of group actions
on a 3×3 square) appeared here the day before  the Friday, Feb. 4, 2011,
Smith College Darwin Mass . . .

From today's online Harvard Crimson

"I open my textbook to page 48, where I’m greeted by
the Russian word for 'hopeless' in bold typeface.
I chuckle, and my Russian teacher throws me a look
of concern. For a moment, I contemplate telling her
the truth: that I find the word 'hopeless' funny, that
I find entertainment in life’s small, meaningless ironic
miseries. I open my mouth, only to mutter 'ничего,' 
the Russian word for 'nothing.' As she turns to face
the blackboard, I silently laugh in my head;
sometimes dark humor is best enjoyed alone."

Another 35-Year Wait

Filed under: Uncategorized — Tags: — m759 @ 9:00 PM

The title refers to today's earlier post "The 35-Year Wait."

A check of my activities 35 years ago this fall, in the autumn
of 1982, yields a formula I prefer to the nonsensical, but famous,
"canonical formula" of Claude Lévi-Strauss.

The Lévi-Strauss formula

My "inscape" formula, from a note of Sept. 22, 1982 —

S = f ( f ( X ) ) .

Still Point for a Dance

"At the still point of the turning world. Neither flesh nor fleshless;
Neither from nor towards; at the still point, there the dance is,
But neither arrest nor movement. And do not call it fixity,
Where past and future are gathered. Neither movement from nor towards,
Neither ascent nor decline. Except for the point, the still point,
There would be no dance, and there is only the dance."

From a web page quoted here on the
Feast of St. Louis, 2003 —

Case 9 of  Hekiganroku: 
Joshu's Four Gates

A monk asked Joshu,
"What is Joshu?" (Chinese: Chao Chou)

Joshu said,
"East Gate, West Gate,
 North Gate, South Gate."

Setcho's Verse:

Its intention concealed,
    the question came;
The Diamond King's eye was
    as clear as a jewel.
There stood the gates,
    north, south, east, and west,
But the heaviest hammer blow
    could not open them.

Two Zen Classics, 1977, p. 172)

The epigraph to Lefebvre's
The Production of Space   (1974, translated in 1991) —

in ¿Águila o Sol?  (1951).)

Broken Symmetries

Filed under: Uncategorized — Tags: — m759 @ 11:00 AM

From posts tagged Design Deadline

A quotation from Lefebvre:

"… an epoch-making event so generally ignored
that we have to be reminded of it at every moment.
The fact is that around 1910 a certain space was shattered…
the space… of classical perspective and geometry…."

— Page 25 of The Production of Space 
    (Blackwell Publishing, 1991)

This suggests, for those who prefer Harvard's past glories
to its current state, a different Raum  from the Zeit  1910.

In January 1910 Annals of Mathematics , then edited at Harvard,
published George M. Conwell's "The 3-space PG (3, 2) and Its Group."
This paper, while perhaps neither epoch-making nor shattering, has
a certain beauty. For some background, see this journal on February 24, 2009.
