Scope Resolution

Filed under: General — Tags: , — m759 @ 9:00 AM

Wikipedia on a programming term

The scope resolution operator helps to identify
and specify the context to which an identifier refers,
particularly by specifying a namespace. The specific
uses vary across different programming languages
with the notions of scoping.  In many languages
the scope resolution operator is written

 "::".

In a completely different context, these four dots might represent
a geometric object  — the four-point plane .

Her Work

Filed under: General — m759 @ 11:35 PM

From the above L.A. Times  article

Where then does the morbid negativity in her work come from?

"Oh boy! That's an even bigger mystery," Andres says, laughing. "You see, I don't like talking about this stuff, because it has to do with psychic phenomena and stuff going on inside me I don't necessarily understand or want to understand. But the truth is that there is some pretty dark and scary content in the work, an acceptance of dark energies which exist whether we like it or not.

"I am mostly interested in getting at a place, a mental reality, that the day-to-day human body couldn't express: a half-way place between film and the body that points to a strange, unexplainable way of seeing stuff, of feeling stuff, of knowing stuff, of being completely different."

The New York Times  this evening reports that Andres died on Jan. 6.

"Here is a recipe for preparing a copy of the Mathieu group M24.
The main ingredient is a genus-3 regular polyhedron X

The most delicate part of this recipe is to hold the polyhedron
by the 24 vertices and immerse the rest of it in 3-dimensional space."

Two examples from the Wikipedia article  "Archimedean solid" —

Iain Aitchison said in a talk last year at Hiroshima that
the Mathieu group M24  can be represented as permuting
naturally the 24 edges  of the cuboctahedron.

The 24 vertices  of the truncated  octahedron are labeled 
naturally by the 24 elements of S4  in a permutahedron

Can M24  be represented as permuting naturally
the 24 vertices  of the truncated octahedron?

Resonant Clarity

Filed under: General — Tags: , , — m759 @ 11:00 AM
 

Abstract for a talk at the City University of New York:

The Experience of Meaning 
Jan Zwicky, University of Victoria 
09:00-09:40 Friday, April 5, 2013

Once the question of truth is settled, and often prior to it, what we value in a mathematical proof or conjecture is what we value in a work of lyric art: potency of meaning. An absence of clutter is a feature of such artifacts: they possess a resonant clarity that allows their meaning to break on our inner eye like light. But this absence of clutter is not tantamount to 'being simple': consider Eliot's Four Quartets  or Mozart's late symphonies. Some truths are complex, and they are simplified  at the cost of distortion, at the cost of ceasing to be  truths. Nonetheless, it's often possible to express a complex truth in a way that precipitates a powerful experience of meaning. It is that experience we seek — not simplicity per se , but the flash of insight, the sense we've seen into the heart of things. I'll first try to say something about what is involved in such recognitions; and then something about why an absence of clutter matters to them.
