"Edward Bulwer-Lytton (infamous author of the opening line,
'It was a dark and stormy night') was a Victorian-era writer.
In 1870, he published a science fiction novel, The Power of
the Coming Race,
 which describes an underground race of
superhuman angel-like creatures and their mysterious energy
force, Vril, an 'all-permeating fluid' of limitless power."

Summa Mythologica

Filed under: General,Geometry — Tags:  — m759 @ 10:10 PM 

Book review by Jadran Mimica in Oceania, Vol. 74, 2003:

"In his classic essay of 1955 'The Structural Study of Myth' Levi-Strauss came up with a universal formula of mythopoeic dynamics

[fx(a) : fy(b) :: fx(b) : fa-1(y)]

that he called canonical 'for it can represent any mythic transformation'. This formulation received its consummation in the four massive Mythologiques volumes, the last of which crystallises the fundamental dialectics of mythopoeic thought: that there is 'one myth only' and the primal ground of this 'one' is 'nothing'. The elucidation of the generative matrix of the myth-work is thus completed as is the self-totalisation of both the thinker and his object."

So there.

At least one mathematician has claimed that the Levi-Strauss formula makes sense. (Jack Morava, arXiv pdf, 2003.)

I prefer the earlier (1943) remarks of Hermann Hesse on transformations of myth:

"…in the spirit of the Glass Bead Game, everything actually was all-meaningful, that every symbol and combination of symbols led not hither and yon, not to single examples, experiments, and proofs, but into the center, the mystery and innermost heart of the world, into primal knowledge. Every transition from major to minor in a sonata, every transformation of a myth or a religious cult, every classical or artistic formulation was, I realized in that flashing moment, if seen with a truly meditative mind, nothing but a direct route into the interior of the cosmic mystery, where in the alternation between inhaling and exhaling, between heaven and earth, between Yin and Yang, holiness is forever being created."

Kaleidoscopic Structuralism

Filed under: General — Tags: , , — m759 @ 2:10 pm

The previous post suggests two quotes by Elizabeth Janeway 
from her review of the second volume of The Human Predicament ,
an unfinished trilogy by Richard Hughes.

"The Human Predicament  poses a universal question, and Hughes
is grappling with it really as a structuralist  philosopher."

"Hughes's style is kaleidoscopic , the shaking of vivid moments together
until a pattern emerges." 

— The New York Times Book Review Sunday, August 19, 1973, page 2

For a less literary example of kaleidoscopic structuralism, see

“The History of the Concept of Structure”

Filed under: General — Tags: , — m759 @ 2:41 pm
 

Derrida was the final speaker on the final day. He remained a silent observer for much of the symposium. He looked on as Lacan rose to his feet with obscure questions at the end of each lecture, and as Barthes gently asked for clarification on various moot points. Eventually, however, Derrida, unused to speaking to large audiences, took to the stage, quietly shuffled his notes, and began, ‘Perhaps something has occurred in the history of the concept of structure that could be called an “event”…’ He spoke for less than half an hour. But by the time he was finished the entire structuralist project was in doubt, if not dead. An event had occurred: the birth of deconstruction.

Excerpt from a long poem by Eliza Griswold


The square array above does not  contain Arfken's variant
labels
for ρ1, ρ2, and ρ3, although those variant labels were
included in Arfken's 1985 square array and in Arfken's 1985
list of six anticommuting sets, copied at MathWorld as above.
The omission of variant labels prevents a revised list of the
six anticommuting sets from containing more  distinct symbols
than there are matrices.

Revised list of anticommuting sets:

α1   α2   α3  ρ2  ρ3

γ1   γ2   γ3   ρ1   ρ

δ δ2   δ ρ1   ρ2 

α1    γ1   δσ2  σ3 

α  γ2   δσ1   σ3

α  γ3   δ3  σ1   σ2  .

Annals of Iconic Simplicity

Filed under: General — Tags: — m759 @ 4:16 pm

The New York Times today has an obituary for
Kevin Lippert, the founder and publisher of
Princeton Architectural Press, who reportedly
died at 63 on March 29, 2022.

“'There was a space between the academic,
theory-heavy M.I.T. Press and the coffeetableism
of Rizzoli,' Mr. Lamster wrote, adding that
Princeton Architectural Press would fill the gap
with 'the voice of the young practitioner.'

Mr. Lippert championed emerging architects.
He published Steven Holl’s seminal architectural
manifesto, 'Anchoring,' in 1989, and wrote the
introduction to the book of the same name.
Mr. Holl, in a tribute to Mr. Lippert on his website,
called him 'a committed intellectual and impresario
for the culture of architecture.'”

— Katharine Q. Seelye, April 17, 2022, 2:21 p.m. ET

From the cited tribute to Lippert on Holl's website —

"An excerpt from his publisher’s foreword to Anchoring 

In its iconic simplicity, his work seems to be about
the language of architecture, not in the allusive sense
used by postmodernists nor in the paradigmatic sense
used by so-called 'deconstructivists' but at the level of
essences of tropes and morphs He is the only
American architect of his generation to be directly
influenced by the main lines in modern philosophy and
music, that is to say, by the line leading from Husserl
through to Heidegger and by separate achievements
of Bartok and Schonberg .
"

Actually, although the above "iconic simplicity" passage,
up to the ellipsis after "morphs,"  is  from the foreword
by Lippert, the references that follow the ellipsis — to
Husserl, Heidegger, Bartok, and Schonberg — are not
from Lippert's foreword, but from the introduction  by
one Kenneth Frampton

On Sept. 12, 2001, The Washington Post published 
an opinion essay by General Boyd in which he wrote,
“While we may feel at the moment as though we are
in a trance, we are, in fact, awakening.”

Pythagorean theorem proof by similarly divided squares

Update of 11:30 AM ET April 1, 2022 — A simpler version:

The above picture may be used to to introduce the concept of a "shape constant"
in similar figures — like the shape constant pi  in a circle or the square root of 2
in a square. In each of the three similar figures at right above, the ratio of the
triangular area to the area of the attached square is a shape constant  
the same, because of their similarity, for each of the three shapes. Since the
areas of the top two triangles at right sum to that of the enclosed triangle at left,
their attached square areas sum to the area of the bottom square, Q.E.D.

From a March 18  post, a flashback to February —

"In The Girl Before, the house is almost a shapeshifter as it fits
the needs of the story. Sometimes it feels like an art gallery,
with its inhabitants on display. It's a smart home (of course it is),
and its automated locks and lights and creepily intuitive A.I.
give it the feel of a high-tech prison. Sometimes it's a mausoleum
for Jane, who's dealing with the recent pain of a miscarriage.
Sometimes it's a fortress for Emma, who's dealing with the recent
trauma of a home invasion." —  Joe Reid at Primetimer.com.

She had seen “The Witch” and introduced Eggers

Eggers read Sjón’s books. “I was, like, this guy’s

"Genealogy of the Image in Histoire(s) du Cinéma : Godard, Warburg and the Iconology of the Interstice"

By Dimitrios S. Latsis

* * * * P. 777 —

Godard conceives of the image only in the plural, in the intermediate space between two images, be it a prolonged one (in  Histoire(s)  there are frequent instances of black screens) or a non-existent one (superimposition, co-presence of two images on screen). He comments: ‘[For me] it’s always two, begin by showing two images rather than one, that’s what I call image, the one made up of two’ [18] and elsewhere, ‘I perceived . . . cinema is that which is between things, not things [themselves] but between one and another.’ [19]

Watchmen Squid Game: Pronoun Trouble

Filed under: General — Tags: — m759 @ 8:05 am

"… Wade’s entire life is built around the squid attack. In the episode’s opening, we see that 34 years ago, young Wade was at a carnival in Hoboken, New Jersey, proselytizing as a Jehovah’s Witness when the squid emitted a psychic blast that killed three million people in the New York area. Just before the attack, a girl led him into a house of mirrors, feigning interest in hooking up with him in order to steal his clothes, leaving him naked and humiliated in the fairground attraction. But the cruel prank also saved his life, as mirrors can apparently repel the squid's psychic blast."

Related literary remarks —

"It may have been by chance, and it may have had the side effect of being easy to read, but this way of putting a novel together offered a bridge between the miniaturist in Doerr and the seeker of world-spanning connections. He could focus on the details of every piece in the narrative, but there was pleasure, too, in placing them against each other. Sometimes he would lay out all these micro chapters on the floor so he could see them and discover the resonances between characters across space and time.

'That’s the real joy,' Doerr said, 'the visceral pleasure that comes from taking these stories, these lives, and intersecting them, braiding them.'"

— "A version of this article appears in print on Sept. 20, 2021, Section C, Page 4 of the New York edition with the headline: Bringing His Readers To Higher Ground."
