Epigraph to The Dark Interval ,  by John Dominic Crossan —

“I am the pause between two notes that fall
into a real accordance scarce at all:
for Death’s note tends to dominate
Both, though, are reconciled in the dark interval,
tremblingly.
                And the song remains immaculate.”

—Rilke, The Book of Hours , I 

"What we do may be small, but it has
a certain character of permanence."

Design Warmed Over

Filed under: General — m759 @ 1:00 pm

Today's announcement of the 2019 Pritzker Architecture Prize
to Arata Isozaki suggests a review.

Isozaki designed the Museum of Contemporary Art building
in Los Angeles in 1986.

Death of a Salesman

Filed under: General — Tags: — m759 @ 12:00 pm

Yesterday's online LA Times  had an obituary for a
traveling salesman:

"Besides writing and teaching, Borg was a frequent speaker,
usually racking up 100,000 frequent flier miles a year.
He and Crossan, along with their wives, led annual tours
to Turkey to follow the path of the Apostle Paul and to give
a sense of his world. They also led tours to Ireland to
showcase a different brand of Christianity."

Borg and Crossan were members of the Jesus Seminar.
For Crossan, see remarks on "The Story Theory of Truth."

See also, from the date of Borg's death, a different salesman joke.

Some backstory —

Inscribed hexagon (1984)

The well-known fact that a regular hexagon
may be inscribed in a cube was the basis
in 1984 for two ways of coloring the faces
of a cube that serve to illustrate some graphic
aspects of embodied Galois geometry

Inscribed hexagon (2013)

A redefinition of the term "symmetry plane"
also uses the well-known inscription
of a regular hexagon in the cube—

Edifice Complex

Filed under: General,Geometry — Tags: , , , — m759 @ 7:00 pm

"Total grandeur of a total edifice,
Chosen by an inquisitor of structures
For himself. He stops upon this threshold,
As if the design of all his words takes form
And frame from thinking and is realized."

— Wallace Stevens, "To an Old Philosopher in Rome"

The following edifice may be lacking in grandeur,
and its properties as a configuration  were known long
before I stumbled across a description of it… still…

 a certain character of permanence…."

For some background, see Configurations and Squares.

For some quite different geometry of the 4×4 square that  is
original with me, see a page with that title. (The geometry's
importance depends in part on its connection with the
Miracle Octad Generator (MOG) of R.T. Curtis. I of course
had nothing to do with the MOG's discovery, but I do  claim credit
for discovering some geometric properties of the 4×4 square
that constitutes two-thirds of the MOG as originally defined .)
