Philip K. Dick,
1928 – 1982

a 1987 edition of
his 1959 novel
Time Out of Joint:

Philip K. Dick as a
window wraith (see below)

The above illustration was suggested by yesterday's quoted New Yorker characterization by Adam Gopnik of Philip K. Dick–

"… the kind of guy who can't drink one cup of coffee without drinking six, and then stays up all night to tell you what Schopenhauer really said and how it affects your understanding of Hitchcock and what that had to do with Christopher Marlowe."

— as well as by the illustrations of Gopnik's characterization in Kernel of Eternity, and by the following passage from Gopnik's 2005 novel The King in the Window:

"What's a window wraith?"

"It's someone who once lived in the ordinary world who lives now in a window, and makes reflections of the people who pass by and look in."

"You mean you are a ghost?!" Oliver asked, suddenly feeling a little terrified.

"Just the opposite, actually. You see, ghosts come from another world and haunt you, but window wraiths are the world. We're the memory of the world. We're here for good. You're the ones who come and go like ghosts. You haunt us."

Related material: As noted, Kernel of Eternity, and also John Tierney's piece on simulated reality in last night's online New York Times. Whether our everyday reality is merely a simulation has long been a theme (as in Dick's novel above) of speculative fiction. Interest in this theme is widespread, perhaps partly because we do exist as simulations– in the minds of other people. These simulations may be accurate or may be– as is perhaps Gopnik's characterization of Philip K. Dick– inaccurate. The accuracy of the simulations is seldom of interest to the simulator, but often of considerable interest to the simulatee.

The cover of the Aug. 20 New Yorker in which the Adam Gopnik essay appears may also be of interest, in view of the material on diagonals in the Log24 entries of Aug. 1 linked to in yesterday's entry:

Adam Gopnik in
The New Yorker of
August 20, 2007–

On Philip K. Dick:

"… the kind of guy who can't drink one cup of coffee without drinking six, and then stays up all night to tell you what Schopenhauer really said and how it affects your understanding of Hitchcock and what that had to do with Christopher Marlowe."

Modernity: A Film by
Alfred Hitchcock
:

"… the most thoroughgoing modernist design element in Hitchcock's films arises out of geometry, as Francois Regnault has argued, identifying 'a global movement for each one, or a "principal geometric or dynamic form," which can appear in the pure state in the credits….'" –Peter J. Hutchings (my italics)

Epilogue:

Adam Gopnik is also the author
of The King in the Window, a tale
of the Christian feast of Epiphany
and a sinister quantum computer.

The Geometry of Qubits

In the context of quantum information theory, the following structure seems to be of interest–

"… the full two-by-two matrix ring with entries in GF(2), M2(GF(2))– the unique simple non-commutative ring of order 16 featuring six units (invertible elements) and ten zero-divisors."

— "Geometry of Two-Qubits," by Metod Saniga (pdf, 17 pp.), Jan. 25, 2007

A 16-element affine space and a corresponding 16-element matrix ring

This ring is another way of looking at the 16 elements of the affine space A4(GF(2)) over the 2-element field.  (Arrange the four coordinates of each element– 1's and 0's– into a square instead of a straight line, and regard the resulting squares as matrices.)  (For more on A4(GF(2)), see Finite Relativity and related notes at Finite Geometry of the Square and Cube.)  Using the above ring, Saniga constructs a system of 35 objects (not unlike the 35 lines of the finite geometry PG(3,2)) that he calls a "projective line" over the ring.  This system of 35 objects has a subconfiguration isomorphic to the (2,2) generalized quadrangle W2 (which occurs naturally as a subconfiguration of PG(3,2)– see Inscapes.)

Saniga concludes:
 

"We have demonstrated that the basic properties of a system of two interacting spin-1/2 particles are uniquely embodied in the (sub)geometry of a particular projective line, found to be equivalent to the generalized quadrangle of order two. As such systems are the simplest ones exhibiting phenomena like quantum entanglement and quantum non-locality and play, therefore, a crucial role in numerous applications like quantum cryptography, quantum coding, quantum cloning/teleportation and/or quantum computing to mention the most salient ones, our discovery thus

  • not only offers a principally new geometrically-underlined insight into their intrinsic nature,
  • but also gives their applications a wholly new perspective
  • and opens up rather unexpected vistas for an algebraic geometrical modelling of their higher-dimensional counterparts."
It would seem that my own
study of pure mathematics
for instance, of the following
"diamond ring"–

is not without relevance to

Four Colours

The previous entry dealt with Plato's myth of the ring of Gyges that conferred invisibility. Another legendary ring, from Hermann Hesse, with some background from Carl Jung:

From C. G. Jung, Collected Works (Princeton U. Press), Volume 12– Psychology and Alchemy (1944)– Part II– "Individual Dream Symbolism in Relation to Alchemy"– Chapter 3, "The Symbolism of the Mandala"– as quoted in Jung, Dreams, published by Routledge, 2001– Page 265–
 

"… the dreamer is wandering about in a dark cave, where a battle is going on between good and evil. But there is also a prince who knows everything. He gives the dreamer a ring set with a diamond….

Visual impression (waking dream):

The dreamer is falling into the abyss. At the bottom there is a bear whose eyes gleam alternately in four colours: red, yellow, green, and blue. Actually it has four eyes that change into four lights. The bear disappears and the dreamer goes through a long dark tunnel. Light is shimmering at the far end. A treasure is there, and on top of it the ring with the diamond. It is said that this ring will lead him on a long journey to the east."

Hermann Hesse, The Journey to the East (1932):

"'… Despair is the result of each earnest attempt to go through life with virtue, justice, and understanding and to fulfil their requirements. Children live on one side of despair, the awakened on the other side. Defendant H. is no longer a child and is not yet fully awakened. He is still in the midst of despair. He will overcome it and thereby go through his second novitiate. We welcome him anew into the League, the meaning of which he no longer claims to understand. We give back to him his lost ring, which the servant Leo has kept for him.'

The Speaker then brought the ring, kissed me on the cheek and placed the ring on my finger. Hardly had I looked at the ring, hardly had I felt its metallic coolness on my fingers, when a thousand things occurred to me, a thousand inconceivable acts of neglect. Above all, it occurred to me that the ring had four stones at equal distances apart, and that it was a rule of the League and part of the vow to turn the ring slowly on the finger at least once a day, and at each of the four stones to bring to mind one of the four basic precepts of the vow. I had not only lost the ring and had not once missed it, but during all those dreadful years I had also no longer repeated the four basic precepts or thought of them. Immediately, I tried to say them again inwardly. I had an idea what they were, they were still within me, they belonged to me as does a name which one will remember in a moment but at that particular moment cannot be recalled. No, it remained silent within me, I could not repeat the rules, I had forgotten the wording. I had forgotten the rules; for many years I had not repeated them, for many years I had not observed them and held them sacred– and yet I had considered myself a loyal League brother.

The Speaker patted my arm kindly when he observed my dismay and deep shame."

The Ring of Gyges

10:31:32 AM ET

Commentary by Richard Wilhelm
on I Ching Hexagram 32:

"Duration is… not a state of rest, for mere standstill is regression.
Duration is rather the self-contained and therefore self-renewing
movement of an organized, firmly integrated whole, taking place in
accordance with immutable laws and beginning anew at every ending."

"Not Being There,"
by Christopher Caldwell
,
from next Sunday's
New York Times Magazine:

"The chance to try on fresh identities was the great boon that life online was supposed to afford us. Multiuser role-playing games and discussion groups would be venues for living out fantasies. Shielded by anonymity, everyone could now pass a 'second life' online as Thor the Motorcycle Sex God or the Sage of Wherever. Some warned, though, that there were other possibilities. The Stanford Internet expert Lawrence Lessig likened online anonymity to the ring of invisibility that surrounds the shepherd Gyges in one of Plato's dialogues. Under such circumstances, Plato feared, no one is 'of such an iron nature that he would stand fast in justice.'Time, along with a string of sock-puppet scandals, has proved Lessig and Plato right."


"The Boy Who Lived,"
by Christopher Hitchens
,
from next Sunday's
New York Times Book Review:

On the conclusion of the Harry Potter series:"The toys have been put firmly back in the box, the wand has been folded up, and the conjuror is discreetly accepting payment while the children clamor for fresh entertainments. (I recommend that they graduate to Philip Pullman, whose daemon scheme is finer than any patronus.)"

I, on the other hand,
recommend Tolkien…
or, for those who are
already familiar with
Tolkien, Plato– to whom
"The Ring of Gyges" may
serve as an introduction.

"It's all in Plato, all in Plato:
bless me, what do they
teach them at these schools!"
C. S. Lewis
