Form and Structure

Filed under: General — m759 @ 11:26 am

In memory of George F. Simmons, a mathematician
who reportedly died Aug. 6 at the age of 94  —

"It seems to me that a worthwhile distinction can be made
between two types of pure mathematics.  The first …
centers attention on particular functions and theorems
which are rich in meaning and history…. The second is
concerned primarily with form and structure."

— George F. Simmons, Introduction to Topology and
     Modern Analysis
(1963)

" . . . Only by the form, the structure, 
Can words or music reach
The stillness . . . ."

— Adapted from T. S. Eliot's Four Quartets 
     
by replacing "pattern" with "structure."

Two posts related to Eliot's theological interests:

Form:  Jan. 10, 2012.
Structure:  June 6, 2016.

"Logos," a Greek word used in philosophy and theology,
is, in modern usage, also a brief form of "logotypes,"
a name for the branding symbols used by businesses.

concept, see Logo in this journal.

Congruent Subarrays

Fury Road: Jukebox Hero*

Filed under: General — Tags: — m759 @ 10:11 pm

"Fury: OK. Your turn. Prove you're not a Skrull.

[Carol calmly blasts energy out of her fists towards a jukebox
on the opposite side of the room before resting her head
back on her fist. Fury continues to look towards the jukebox,
both concerned and confused]

Fury: And how is that supposed to prove to me that you're not a Skrull?

Carol: It's a photon blast.

Fury: And…?

Carol: A Skrull can't do that. So a full-bird colonel turned spy turned
SHIELD agent must have pretty high security clearance. Where's Pegasus?

[The scene changes to a black car driving through an empty highway
next to a mountain, before changing to the inside of the car showing Fury
driving and Carol in the passenger seat]

Fury: So the Skrulls are alien races which infiltrate and overtake alien planets.
And you're a Kree, a race of noble warriors.

Carol: Heroes. Noble warrior heroes."

Schoolgirl Space — Tetrahedron or Square?

Filed under: General — Tags: , , — m759 @ 9:03 pm

The exercise in the previous post  was suggested by a passage
purporting to "use standard block design theory" that was written
by some anonymous author at Wikipedia on March 1, 2019:

Here "rm OR" apparently means "remove original research."

Before the March 1 revision . . .

The "original research" objected to and removed was the paragraph
beginning "To explain this further."  That paragraph was put into the
article earlier on Feb. 28 by yet another anonymous author (not  by me).

An account of my own (1976 and later) original research on this subject 
is pictured below, in a note from Feb. 20, 1986 —

'The relativity problem in finite geometry,' 1986

On Steiner Quadruple Systems of Order 16

Cullinane's 1978  square model of PG(3,2)

The following paragraph from the above image remains unchanged
as of this morning at Wikipedia:

"A 3-(16,4,1) block design has 140 blocks of size 4 on 16 points,
such that each triplet of points is covered exactly once. Pick any
single point, take only the 35 blocks containing that point, and
delete that point. The 35 blocks of size 3 that remain comprise
a PG(3,2) on the 15 remaining points."

Exercise —

Prove or disprove the above assertion about a general "3-(16,4,1) 
block design," a structure also known as a Steiner quadruple system
(as I pointed out in the March 5 post).

Relevant literature —

A paper from Helsinki in 2005* says there are more than a million
3-(16,4,1) block designs, of which only one has an automorphism
group of order 322,560. This is the affine 4-space over GF(2),
from which PG(3,2) can be derived using the well-known process
from finite geometry described in the above Wikipedia paragraph.

Double Veil

Filed under: General — Tags: , , — m759 @ 9:48 pm

"If you want to win, you need to know just one thing and not to waste your time
on anything else: the pleasures of erudition are reserved for losers. The more
a person knows, the more things have gone wrong."

— Eco, Umberto. Numero Zero  (p. 9). HMH Books. Kindle Edition. 

"All this notwithstanding, I dreamed what all losers dream, about one day writing
a book that would bring me fame and fortune. To learn how to become a great
writer, I became what in the last century was called the nègre  (or ghostwriter,
as they say today, to be politically correct) for an author of detective stories who
gave himself an American name to improve sales, like the actors in spaghetti
westerns. But I enjoyed working in the shadows, hidden behind a double veil
(the Other’s and the Other’s other name)."

purchase of the rights to the Harry Potter  books by
