“The Echo in Plato’s Cave” Continues.

Filed under: General — m759 @ 1:00 PM

The previous post, "Colorful Tales," on the Nov. 28, 2016, death
of one Angus Fletcher, together with the remarks indexed above,
suggest a review from 

The archives of The New York Times  —

"THE ANATOMY OF INFLUENCE
Literature as a Way of Life

By Harold Bloom
357 pp. Yale University Press. $32.50.

Sam Tanenhaus is the editor of the Book Review.

A version of this review appeared in print
on May 22, 2011, on Page BR1 of the 
Sunday Book Review with the headline:
'An Uncommon Reader.'"

"By this time, Bloom had burrowed into a cave,
its lamplit forms and shapes merging into
an occult mythos scarcely intelligible
even to other scholars. 'Bloom had an idea,' 
Christopher Ricks said; 'now the idea has him.' 
Cynthia Ozick, meanwhile, called him an 'idol-maker.' 
In contrast to Cleanth Brooks . . . ."

Colorful Tales

Filed under: General — m759 @ 1:23 PM

“Perhaps the philosophically most relevant feature of modern science
is the emergence of abstract symbolic structures as the hard core
of objectivity behind— as Eddington puts it— the colorful tale of
the subjective storyteller mind.”

— Hermann Weyl, Philosophy of  Mathematics and
    Natural Science 
, Princeton, 1949, p. 237

Harvard University Press on the late Angus Fletcher, author of
The Topological Imagination  and Colors of the Mind

From the Harvard webpage for Colors of the Mind

Angus Fletcher is one of our finest theorists of the arts,
the heir to I. A. Richards, Erich Auerbach, Northrop Frye.
This… book…  aims to open another field of study:
how thought— the act, the experience of thinking—
is represented in literature.

. . . .

Fletcher’s resources are large, and his step is sure.
The reader samples his piercing vision of Milton’s

Satan, the original Thinker,
leaving the pain of thinking
as his legacy for mankind.

A 1992 review by Vinay Dharwadker of Colors of the Mind —

A Penny for My Thoughts?
by Maureen Dowd

“If an online newspaper in Pasadena, Calif., can outsource coverage to India, I wonder how long can it be before some guy in Bangalore is writing my column….”

New York Times teaser for a column of Sunday, November 30, 2008 (St. Andrew’s Day)

DH News Service, Bangalore, Tuesday, Dec. 2, 2008:

“Monday evening had a pleasant surprise in store for sky-watchers as the night sky sported a smiley, in the form of a crescent moon flanked by two bright planets Jupiter and Venus…”

Meanwhile, at National Geographic:

Jupiter, Venus, Moon Make “Frown”

A Midrash for Maureen:

The poet’s eye, in fine frenzy rolling,
Doth glance from heaven to earth,
    from earth to heaven;

And as imagination bodies forth
The forms of things unknown,
    the poet’s pen

Turns them to shapes
    and gives to airy nothing

A local habitation and a name.
Such tricks hath strong imagination,
That if it would but
    apprehend some joy,

It comprehends some
    bringer of that joy….”

Cover of  'The Last Theorem,' a novel by Arthur C. Clarke and Frederik Pohl

The Last Theorem
, a novel by
Arthur C. Clarke and Frederik Pohl

From the publisher's description:

"The Last Theorem is a story of one man’s mathematical obsession, and a celebration of the human spirit and the scientific method. It is also a gripping intellectual thriller….

In 1637, the French mathematician Pierre de Fermat scrawled a note in the margin of a book about an enigmatic theorem: 'I have discovered a truly marvelous proof of this proposition which this margin is too narrow to contain.' He also neglected to record his proof elsewhere. Thus began a search for the Holy Grail of mathematics– a search that didn’t end until 1994, when Andrew Wiles published a 150-page proof. But the proof was burdensome, overlong, and utilized mathematical techniques undreamed of in Fermat’s time, and so it left many critics unsatisfied– including young Ranjit Subramanian, a Sri Lankan with a special gift for mathematics and a passion for the famous 'Last Theorem.'

When Ranjit writes a three-page proof of the theorem that relies exclusively on knowledge available to Fermat, his achievement is hailed as a work of genius, bringing him fame and fortune…."

For a similar third-world fantasy about another famous theorem, see the oeuvre of Ashay Dharwadker.

Note the amazing conclusion of Dharwadker's saga (thus far)–

Dharwadker devises a proof of the four-color theorem that leads to…

Grand Unification
of the Standard Model
with Quantum Gravity!

Theories of Everything

Ashay Dharwadker now has a Theory of Everything.
Like Garrett Lisi’s, it is based on an unusual and highly symmetric mathematical structure. Lisi’s approach is related to the exceptional simple Lie group E8.* Dharwadker uses a structure long associated with the sporadic simple Mathieu group M24.

GRAND UNIFICATION

OF THE STANDARD MODEL WITH QUANTUM GRAVITY

by Ashay Dharwadker

Abstract

“We show that the mathematical proof of the four colour theorem [1] directly implies the existence of the standard model, together with quantum gravity, in its physical interpretation. Conversely, the experimentally observable standard model and quantum gravity show that nature applies the mathematical proof of the four colour theorem, at the most fundamental level. We preserve all the established working theories of physics: Quantum Mechanics, Special and General Relativity, Quantum Electrodynamics (QED), the Electroweak model and Quantum Chromodynamics (QCD). We build upon these theories, unifying all of them with Einstein’s law of gravity. Quantum gravity is a direct and unavoidable consequence of the theory. The main construction of the Steiner system in the proof of the four colour theorem already defines the gravitational fields of all the particles of the standard model. Our first goal is to construct all the particles constituting the classic standard model, in exact agreement with t’Hooft’s table [8]. We are able to predict the exact mass of the Higgs particle and the CP violation and mixing angle of weak interactions. Our second goal is to construct the gauge groups and explicitly calculate the gauge coupling constants of the force fields. We show how the gauge groups are embedded in a sequence along the cosmological timeline in the grand unification. Finally, we calculate the mass ratios of the particles of the standard model. Thus, the mathematical proof of the four colour theorem shows that the grand unification of the standard model with quantum gravity is complete, and rules out the possibility of finding any other kinds of particles.”

Hard Core

(continued from yesterday)

Bertram Kostant, Professor Emeritus of Mathematics at MIT, on an object discussed in this week’s New Yorker:

A word about E(8). In my opinion, and shared by others, E(8) is the most magnificent ‘object’ in all of mathematics. It is like a diamond with thousands of facets. Each facet offering a different view of its unbelievable intricate internal structure.”

Hermann Weyl on the hard core of objectivity:

“Perhaps the philosophically most relevant feature of modern science is the emergence of abstract symbolic structures as the hard core of objectivity behind– as Eddington puts it– the colorful tale of the subjective storyteller mind.” (Philosophy of Mathematics and Natural Science, Princeton, 1949, p. 237)


Steven H. Cullinane on the symmetries of a 4×4 array of points:

A Structure-Endowed Entity

“A guiding principle in modern mathematics is this lesson: Whenever you have to do with a structure-endowed entity S, try to determine its group of automorphisms, the group of those element-wise transformations which leave all structural relations undisturbed.  You can expect to gain a deep insight into the constitution of S in this way.”

— Hermann Weyl in Symmetry

Let us apply Weyl’s lesson to the following “structure-endowed entity.”

4x4 array of dots

What is the order of the resulting group of automorphisms?

The above group of
automorphisms plays
a role in what Weyl,
following Eddington,
  called a “colorful tale”–

The Diamond 16 Puzzle

The Diamond 16 Puzzle

This puzzle shows
that the 4×4 array can
also be viewed in
thousands of ways.

“You can make 322,560
pairs of patterns. Each
 pair pictures a different
symmetry of the underlying
16-point space.”

July 17, 2008

A Crackpot with Power

The following is an greatly abbreviated version of a sci.math group thread on an attempted proof of the four-color theorem.

  • Chip Eastham 2000-10-13 :

    There is a nicely presented approach to proving the Four Color Theorem… at the following… site:

    http://www.geocities.com/dharwadker/index.html

  • “Default” 2000-10-13:

    Where in the proof is the hypothesis of “requiring N colors” (not colorable with N-1 colors) used?

  • Michael Varney 2000-10-14:

    (Following some banter) Go play elsewhere if you buy into 4CT crackpot proofs.

  • “Default” 2000-10-14:

    The proposed 4CT proof is hardly crackpot, and may contain some new ideas (or reformulations of old ones).

  • Michael Varney 2000-10-14:

    That’s what all crackpots say. Join the club.

  • David Eppstein 2000-10-14:

    My first-glance reaction is that it’s an amazing collection of undigested chunks of heavy equipment. It seems more designed to confuse any expert (by making sure it contains something the expert doesn’t understand) than to convince anyone of the truth of the 4CT.

  • “Default” 2000-10-15:

    Skimming the proof I did not see any place where the minimality of the chromatic number N was used, nor any explanation of why a 12-fold covering is introduced (other than it fits the numerology needed to rule out a Steiner system). This makes me skeptical about the proof, but it’s hardly crackpot.

The author of this attempted proof, Ashay Dharwadker, is now an editor of the following Open Directory Project categories:

Science: Math: Combinatorics   and
Science: Math: Combinatorics: Graph Theory.

I agree with “Default,” Eppstein, and Varney.

As “Default” notes, the proof is invalid,  since it does not even use the hypotheses of the theorem.  I pointed this out in November 2000 in a sub-page of a website in the Open Directory combinatorics category,

I also agree with Eppstein that Dharwadker’s writing seems “designed to confuse.” 

Finally, I strongly agree with Varney that Dharwadker is a crackpot.  I reluctantly arrived at this conclusion only last night, after learning that

  1. Dharwadker, who formerly had edited only the graph theory Open Directory category, now is a co-editor of its parent category, combinatorics, and that
  2. My website containing a criticism of Dharwadker’s work has been deleted from the Open Directory combinatics listings. This site, “Diamond Theory,” is only incidentally related to Dharwadker’s attempted proof, and has been in the Open Directory combinatorics listing for about two years.  

Crackpots are annoying, but crackpots with power are both contemptible and infuriating.  I am currently trying to rectify the appalling mistake made by whoever appointed Dharwadker to a position of responsibility.
