The Seven-Year Glitch

From a post of March 8, 2017 —

This is from posts tagged Glitch.

"There's plenty of dives
to be someone you're not. . . ."

— Rosanne Cash, Seven-Year Ache

"Dr Kennedy’s project, entitled ‘Identity Deception: A Critical History’,
asks when, if ever, it is appropriate to punish a person who engages
in identity deception (pretending to be someone they are not)."

Babes in Tweeland

Filed under: General — Tags: , — m759 @ 11:44 am

The New Yorker   yesterday on a film director —

"Lest viewers become even briefly comfortable with
the enchantments of his staging and of his actors’
performances, Anderson jolts them alert with
ever more audacious contrivances."

"As you can see, we've had our eye on you
for some time now, Mr. Anderson."

Verba Volant, Scripta Manent

Filed under: General — m759 @ 10:50 am

For  Kristen  Breitweiser

"Daisy, when she comes to tea at Nick's house,
refers to the flowers brought by Gatsby as being
appropriate for a funeral and asks 'Where's the corpse?' 
Gatsby enters immediately thereafter. This foreshadows
what will happen to Gatsby. The dialogue is not in the novel…."

— Discussion of the 2000 TV movie version in
Learning Guide to The Great Gatsby 

Correction to the midrash: 

Sorvino actually says, when there is a knock at the door,

"That must be the corpse."

Jersey girls are tough.

Feature

"… what we’re witnessing is not a glitch. It’s a feature…."

A Boston Globe  columnist on June 19.

Literary Symbolism

"… what we’re witnessing is not a glitch. It’s a feature…."

The glitch  encountered on Bloomsday by Agent Smith (who represents 
the academic world) is the author  of the above page, John P. Anderson.
The feature  is the book  that Anderson quotes, James Joyce 
by Richard Ellmann
(first published in 1959, revised in 1982).

Three Mother Cubes

Filed under: General,Geometry — Tags: , , — m759 @ 1:44 pm

From a Toronto Star video pictured here on April 1 three years ago:

The three connected cubes are labeled "Harmonic Analysis," 'Number Theory,"
and "Geometry."

Related cultural commentary from a review of the recent film "Justice League" —

"Now all they need is to resurrect Superman (Henry Cavill),
stop Steppenwolf from reuniting his three Mother Cubes
(sure, whatever) and wrap things up in under two cinematic
hours (God bless)."

The nineteenth-century German mathematician Felix Christian Klein
as Steppenwolf —

Volume I of a treatise by Klein is subtitled
"Arithmetic, Algebra, Analysis." This covers
two of the above three Toronto Star cubes.

Klein's Volume II is subtitled "Geometry."

An excerpt from that volume —

The Table

Filed under: General,Geometry — m759 @ 12:00 pm

John Horgan and James (Jim) McClellan, according to Horgan
in Scientific American  on June 1, 2017

Me: "Jim, you're a scholar! Professor! Esteemed historian of science! And yet you don’t really believe science is capable of producing truth."

Jim: "Science is stories we tell about nature. And some stories are better than other stories. And you can compare stories to each other on all kinds of grounds, but you have no access to"— he pauses for dramatic effect— "The Truth. Or any mode of knowing outside of your own story-telling capabilities, which include rationality, experiment, explanatory scope and the whole thing. I would love to have some means of making knowledge about the world that would allow us to say, 'This is really it. There really are goddamn electrons.'" He whacks the table.

Inscapes

"The particulars of attention,
whether subjective or objective,
are unshackled through form,
and offered as a relational matrix …."

— Kent Johnson in a 1993 essay

Illustration

Commentary

The 16 Dirac matrices form six anticommuting sets of five matrices each (Arfken 1985, p. 214):

1. alpha_1alpha_2alpha_3alpha_4alpha_5,

2. y_1y_2y_3y_4y_5,

3. delta_1delta_2delta_3rho_1rho_2,

4. alpha_1y_1delta_1sigma_2sigma_3,

5. alpha_2y_2delta_2sigma_1sigma_3,

6. alpha_3y_3delta_3sigma_1sigma_2.

The Matrix Hypothesis

Filed under: General — Tags: , — m759 @ 9:20 am

"And so both of these bizarre events put one in mind of
a simple but arresting thesis: that we are  living in the Matrix,
and something has gone wrong with the controllers. . . .
The people or machines or aliens who are supposed to be
running our lives are having some kind of breakdown.
There’s a glitch, and we are in it.

Once this insight is offered, it must be said, everything  else
begins to fall in order."

Adam Gopnik in The New Yorker , Feb. 27, 2017
