Dear Stan,

I wish I could understan/d you better. Your thought processes are way over my
poor head I'm afraid. My chess abilities have been sadly put to shame by a
seven year old. I'm giving up chess - at least for now.

Carolyn

p.s. I only meant that Dmitri might be able to enlighten us as to his father's
thoughts on the subject.

Re: [NABOKV-L] Chess and the asymetric universe >But I do think the asymmetry of
the board/pieces is of greater importance than Stan admits. (CK).

Carolyn:

Brief overture:

The following two statements are BOTH true ... But INCOMPLETE:

1. The standard* 8 x8 chessboard is SYMMETRICAL
2. The same chessboard is ASYMMETRICAL

(* yes, ‘standard’ means the nearest rightmost square is on the right-hand side
for BOTH players! White Q square d1 is white on left; Black Q square d8 is black
on right. Some of us oldies prefer the English over the Pagan (Algebraic)
notation! White’s Q1 = Black’s Q8; vice versa)

Further progress is a problem unless you understand that symmetry and asymmetry
are properties that depend on WHICH TRANSFORMATIONs you are APPLYING.



1. A Rotation of 180 degrees (clockwise or anti-clockwise) about a vertical
axis through its midpoint leaves the chessboad looking the same => a symmetrical
transformation.

2. A Rotation of 90 degrees about a vertical axis through its midpoint ALTERS
the chessboad’s disposition, INTERCHANGING BLACK/WHITE squares => an
asymmetrical transformation.
Each chess PIECE DESIGN (Staunton etc) has its own set of
symmetries/assymmetries. But you can play Chess with 32 COINS!


Progress Test: are 1 and/or 2 true for a 7 x 7 ‘chessboard?’

As well as these trivial ‘geometrical’ manipulations, there’s an infinite
number of abstract symmetries/asymmetries, many with physical analogues.

What about the following KEY transformation (call it BW) to a fully-populated,
intitial chess board?:
CHANGE WHITE-to-BLACK/BLACK-to-WHITE applied to all squares AND pieces but NOT
to starting RULE? (New White starts):

You’ve effectively achieved a MIRROR reflection (imagine the mirror placed
vertically behind the original “black” player). If I’m standing behind the
original “white” player I now see in the mirror the reflected “black” player,
playing second in the reflected game! So BW and Reflection identically switch
first/second player!


This, I repeat, is the ONLY TRUE game-changing Chess asymmetry: white has a
marginal STATISTICAL advantage. None of the board/piece/setup conventions OFFER
this ADVANTAGE, regardless of mathematical symmetries/asymmetries.


Back to your text:

>Too bad we haven't Dmitri to consult (CK)

As my T-shirt says: “F**k Google. Ask Stan!”

We all miss Dmitri Nabokov, but of his many, many admired achievements, command
of the profound mathematics/physics of symmetry/antisymmetry is not apparent in
any publications I’ve encountered. Refs requested.

His dad’s esteemed corpus does often refer to these concepts (always beautifully
aphoristically!), but at what is a mathematically trivial level compared with
their cosmic implications.


Tongue-in-cheek (advanced readers only ;=)):
Does ignorance or misogyny explain the absence of EMMY NOETHER (1882-1935) in
any of VN’s works? The greatest female mathematician (so far!) whose eponymous
Theorem connects each CONSERVATION LAW with an abstract SYMMETRY group. Their
careers overlapped in space-time and suffering. Emma was expelled from
Go:ttingen in 1933 (the Nazi’s first wave of anti-Semitic legislation) and ended
in the USA (Bryn Mawr, Philadelphia)

Martin Gardener, the late-great maths-amateur popular populariser is a much
better source. By all means read the Ambidextrous Universe. The FIRST thing
you’ll learn is what I said in my Overture.

The statement “X is asymmetrical” is meaningless/incomplete without adding “ ...
(asymmetrical) with respect to some given transformation”


> ... he (MG) does mention that if the universe were not asymmetrical it wouldn't
>exist. In other words, matter and anti-matter would cancel each other out. (CK)

As reported, this is highly garbled and difficult to unwind. MG is referring to
the well-established CHARGE REVERSAL TRANSFORMATION. (Separately C[harge],
[P]arity, and T[ime] REVERSAL are each asymmetric, but combined as CPT, believed
to be symmetric).

Each elementary particle in the Standard Model has an ANTI-particle ‘partner’
(electron/positron; proton/anti-proton, neutrino/anti-neutrino, ...).
With same mass (and other properties) but opposite charge/quantum-spin.
Particles and anti-particles are right NOW colliding EVERYWHERE (INCLUDING
so-called VACUUMS) by the gaZILLIONS into tiny ‘bursts’ of energy (radiation).
The UNIVERSE has NOT disappeared (yet a while) because these particles are ALSO
APPEARING as opposite-C pairs spontaneously in an endless quantum ‘stew.’ Atoms
that make up some of our every matter, have corresponding C-transformed atoms =
anti-matter. CERN has created millions of Anti-Hydrgen atoms and can observe
them for several microseconds (an ETERNITY in quantum terms) before anihilation
... O dear ...


This is major VN-DIGRESSION. Let me refer you to Wiki
At this time, the apparent asymmetry of matter and antimatter in the VISIBLE
universe is one of the greatest unsolved problems in physics

Ending on a VN cum non-Tech Literary-Science note:

Following two quotes are cited in the browsable anthology:
http://www.findingpatterns.info/scrapbook/tag/text

Vladimir Nabokov said of the gap between science and art:
'a mere dimple of a ditch that a small frog could straddle'

Freeman Dyson, end. Chap 1, 'Infinite in all Directions'

"This quick tour of the universe will begin with superstrings and end with
butterflies. There will be a couple of intermediate stops on the way. Like Dante
on his tour of the Inferno, I find at each level some colorful characters to add
human interest to an otherwise intimidating scene. I will not explain what
butterflies and superstrings are. To explain butterflies is unnecessary because
everyone has seen them. To explain superstrings is impossible because nobody has
seen them. But please do not think I am trying to mystify you. Superstrings and
butterflies are examples illustrating two different aspects of the universe and
two different notions of beauty. Super-strings come at the beginning and
butterflies at the end because they are extreme examples. Butterflies are at the
extreme of concreteness, superstrings at the extreme of abstraction. They mark
the extreme limits of the territory over which science claims jurisdiction. Both
are, in their different ways, beautiful. Both are, from a scientific point of
view, poorly understood. Scientifically speaking, a butterfly is at least as
mysterious as a superstring. When something ceases to be mysterious it ceases to
be of absorbing concern to scientists. Almost all the things scientists think
and dream about are mysterious...................

I was thinking of Lewis Carroll of course (the Red Queen and theRed King) and
you are right - something I never seem to get correct is that the Queen is on
