Something to Read
Eric M. Friedlander, President of the
American Mathematical Society (AMS),
in the March 2011 AMS Notices —
"I think the best thing the AMS does by far is the Notices .
It could easily be in all doctors’ and dentists’ offices."
Notices : "Really?"
Friedlander: "It could be."

Stevie Nicks

On the author discussed
here yesterday,
Siri Hustvedt:
“… she explores
the nature of identity
in a structure* of
crystalline complexity.”

J. G. Ballard on "the architecture of death":
"… a huge system of German fortifications that included the Siegfried line, submarine pens and huge flak towers that threatened the surrounding land like lines of Teutonic knights. Almost all had survived the war and seemed to be waiting for the next one, left behind by a race of warrior scientists obsessed with geometry and death."
— The Guardian, March 20, 2006
From the previous entry, which provided a lesson in geometry related, if only by synchronicity, to the death of Jewish art theorist Rudolf Arnheim:
"We are going to keep doing this until we get it right."
Here is a lesson related, again by synchronicity, to the death of a Christian art scholar of "uncommon erudition, wit, and grace"– Robert R. Wark of the Huntington Library. Wark died on June 8, a date I think of as the feast day of St. Gerard Manley Hopkins, a Jesuit priest-poet of the nineteenth century.
From a Log24 entry on the date of Wark's death–
Samuel Pepys on a musical performance (Diary, Feb. 27, 1668):
"When the Angel comes down"
"When the Angel Comes Down, and the Soul Departs," a webpage on dance in Bali:
"Dance is also a devotion to the Supreme Being."
"I went to Bali to a remote village by a volcanic mountain…."
The above three quotations were intended to supply some background for a link to an entry on Taymor, on what Taymor has called "skewed mirrors," and on a related mathematical concept named, using a term Hopkins coined, "inscapes."
They might form part of an introductory class in mathematics and art given, like the class of the previous entry, in Purgatory.
Wark, who is now, one imagines, in Paradise, needs no such class. He nevertheless might enjoy listening in.

The Crown of Geometry
(according to Logothetti
in a 1980 article)
The crown jewels are the
Platonic solids, with the
icosahedron at the top.
Related material:
"[The applet] Syntheme illustrates ways of partitioning the 12 vertices of an icosahedron into 3 sets of 4, so that each set forms the corners of a rectangle in the Golden Ratio. Each such rectangle is known as a duad. The short sides of a duad are opposite edges of the icosahedron, and there are 30 edges, so there are 15 duads.
Each partition of the vertices into duads is known as a syntheme. There are 15 synthemes; 5 consist of duads that are mutually perpendicular, while the other 10 consist of duads that share a common line of intersection."

That essay was written 15 years

to be the birthday of
Sir Laurence Olivier, who,
were he alive today, would
be 100 years old.
