Broomsday Revisited

Filed under: General,Geometry — m759 @ 9:29 AM

Ivars Peterson in 2000 on a sort of conceptual art —

" Brill has tried out a variety of grid-scrambling transformations
to see what happens. Aesthetic sensibilities govern which
transformation to use, what size the rectangular grid should be,
and which iteration to look at, he says. 'Once a fruitful
transformation, rectangle size, and iteration number have been
found, the artist is in a position to create compelling imagery.' "

"Scrambled Grids," August 28, 2000

Or not.

If aesthetic sensibilities lead to a 23-cycle on a 4×6 grid, the results
may not be pretty —

From "Geometry of the 4×4 Square."

Brick Joke

Filed under: General — Tags: , , — m759 @ 10:56 AM

The “bricks” in posts tagged Octad Group suggest some remarks
from last year’s HBO “Watchmen” series —

Related material — The two  bricks constituting a 4×4 array, and . . .

“(this is the famous Kummer abstract configuration )”
Igor Dolgachev, ArXiv, 16 October 2019.

As is this


The phrase “octad group” does not, as one might reasonably
suppose, refer to symmetries of an octad (a “brick”), but
instead to symmetries of the above 4×4 array.

"You could say UD  currently sits (she’s in the library
at five AM) at the pinnacle of elitism; you could say
she ain’t climbing any higher than atop this soft
leather chair resting on one of the gargantuan rugs
Galbraith or Galbraith junior brought back from India
or Afghanistan. But it’s only the trappings. What’s
been able to be held in amber. This place is the
genuine Henry James (Harvard Law, 1872):
The affluent society, expansive, sedate; and
the cry of pain almost out of earshot."

Presumably UD  means the noted author Henry James.
A fact check does not bear out her "Harvard Law, 1872" remark.

Seeking Kleos

Filed under: General — Tags: — m759 @ 6:22 PM

Rebecca Newberger Goldstein, quoted in a webpage dated
October 7, 2014 (presumably according to Australian time):

"For the Athenians, kleos  mattered more than anything,
according to Goldstein.

'Kleos  is fame: it’s the deed that brings fame, it’s the poem
that sings your triumphs, it’s having your life replicated in
other minds, acquiring a kind of moreness, a kind of
secular immortality.' "

Wikipedia on Broom (or Broome, or Brougham) Bridge,
where on 16 October 1843 Hamilton discovered quaternions:

"The 16 October is sometimes referred to as
Broomsday (in reference to Broome Bridge)
and as a nod to the literary commemorations
on 16 June (Bloomsday in honour of James Joyce)."

Up the River

The careful reader will note that the previous entry has two parts.

Part I, “Spain,” links to the home page of a Spaniard named Jesús.

Part II, “Take This Cup,” links to a page about a poet named César.

I found Jesús in a search for images of “Apocalypse Now” prompted in turn by earlier entries.

I knew of César from library browsing.

This afternoon, I looked at the home page of the site where I found the essay on César; this in turn led to another essay:

The Necessity For Story

by  Frederick Zackel

While it’s a story that’s never been written, a suggested title– Indiana Jones Sails Up The River Of Death–

The image “http://www.log24.com/log/pix04B/041016-Poster2.jpg” cannot be displayed, because it contains errors.

shows how readily we as individuals or we as a culture can automatically visualize a basic story motif. We may each see the particular elements of the story differently, but almost instantaneously we catch its drift.

The hero sails up the river of death to discover what lies within his own heart: i.e., how much moral and physical strength he has.

Indiana Jones sails up the River of Death.

We are following Indiana Jones up the River of Death. We’re going to visit with Colonel Kurtz. (You may not want to get off the boat.)

No, I am not mixing up metaphors.

These are the Story.

For what it’s worth, the birthday of Jesús is April 9… See the entry of April 9, 2003, “Hearts of Darkness.”

The birthday of César is March 16.  See the entry of March 16, 2003,  on the letter A… Here is the logo of the site where I found both César and “The Necessity For Story”–

Midnight in the Garden

Umberto Eco,
Foucault’s Pendulum,
page 176:

Here, too, you entered through a little garden…

Amparo drew me aside as we went in.  “I’ve figured it out,” she said.  “That tapir at the lecture talked about the Aryan age, remember?  And this one talks about the decline of the West.  Blut und Boden, blood and earth.  It’s pure Nazism.”

“It’s not that simple, darling.  This is a different continent.”….

If the outside was seedy, the inside was a blaze of violent colors.  It was a quadrangular hall, with one area set aside for the dancing of the cavalos.  The altar was at the far end, protected by a railing, against which stood the platform for the drums, the atabaques.  The ritual space was still empty….

Atabaque – a large tom-tom
that is used in Afro-Brazilian
religious celebrations”

“Of African origin, and made of jacarandá wood in a conical shape. A calfskin head covers the top of the drum. It is used a lot in capoeria and candomblé and umbanda rituals all over Brazil. There are three kinds of atabaques: Rum, Rumpi, and Lê. Rum has the deepest sound and is a solo drum; Rumpi has a medium sound, and Lê is the highest. These three hold the beat.”

Like the beat, beat, beat of the tom-tom….

— Cole Porter, “Night and Day

Your feats end enormous,
    your volumes immense,
(May the Graces I hoped for
    sing your Ondtship song sense!),
Your genus its worldwide,
    your spacest sublime!
But, Holy Saltmartin,
    why can’t you beat time?

In the name of the former
    and of the latter
    and of their holocaust. Allmen.
