neil, thanks a lot...
years ago, i wrote a short storie, sinister,
in spanish siniestra
which can be the name of a woman, a property of a sort of darkness, or
it can refer to left sides too...
that woman had a problem, a progresive sickness... her left side was
melting down, sort of melting down...
the idea shocked me so much that i made a drawing of a nude women sat on
a elegant armchair with her right side like a beautiful woman and with
her left side like a mess mass hunged at her right side of the body.
this was funny, but there is more...
i've already share with you that i suffer dislexy, even typing, not only
writing... i change b and p
i'm really interested on the differences between our 2 cerebral
hemispheres...
marchall mc luhan worked with it, and each hemisphere have a property.
but the funny thing is that the capacity of language or motion or making
music is not placed simetric in our brain... or i have not the right
information...
....
did the speakers talk about god or a similar entity?
did they lucubrate about god symmetry?
as far as i've read (the 3 books and other religious text), god is not
worry about symetry, but he "created" a symmetric nature.
as far as i remember, no kabala writer wrote about the symmetric
event... sufi poetry or bagavad ghita...
... may be sacred music (christian, jew, sufi or hinduist...)
...
did gilles deleuze talked about symmetrics in the rizoma?
i did not find it.
i think we have french members in NetB that can know about it.
i mean, there may be members in NetB who know more about what i've
commented... if i'm wrong in any hypothesis, please, tell me, even if i
talk from the wrong point of view... the wrong place to watch at it.
---
in my creative work, i always break symmetry because i feel my brain
when it stands in front of asymmetries: i feel physically how it works !
one of the things i'm doing is working at the input of sound: i record
my voice from left speaker to right speaker and so on, and that makes a
sort of brain massage... try it...
what my brain feels in front of symmetries is... relief !
and, for instances, drawing symmetric mandalas smooth me down
isn't it funny?

early neolithic sculptures in regular forms, cognitive recognition of
symmmetric forms (by animals/humans and artists), cuniform, babylonian
maths and greek geometry, methods for solving (and working out)
quadratic and cubic equations (respectively) - (method and conic
sections), algebra in place of derived solution tables, mathematical
transformations and group theory (*no transformation is part of the
subset of symmetrical transformations, or 'operations' - nothing is
something.. ), the alhambra, bell ringing, the lack of a solution for
quintic equations and 'atoms' of symmetry - shapes divided by shapes,
indivisible symmetries
phew.. i won't start on the last 20 minutes and misquote einstein :)

neil, if you go,
could you write just a little bit of what you heard there?
(pleasepleaseplease)

SYMMETRY
Today we will be discussing symmetry, from the most perfect forms in
nature, like the snowflake and the butterfly, to our perceptions of
beauty in the human face. There's symmetry too in most of the laws
that govern our physical world.
The Greek philosopher Aristotle described symmetry as one of the
greatest forms of beauty to be found in the mathematical sciences,
while the French poet Paul Valery went further, declaring; “The
universe is built on a plan, the profound symmetry of which is
somehow present in the inner structure of our intellect”.
The story of symmetry tracks an extraordinary shift from its role as
an aesthetic model - found in the tiles in the Alhambra and Bach's
compositions - to becoming a key tool to understanding how the
physical world works. It provides a major breakthrough in
mathematics with the development of group theory in the 19th
century. And it is the unexpected breakdown of symmetry at
sub-atomic level that is so tantalising for contemporary quantum
physicists.
So why is symmetry so prevalent and appealing in both art and
nature? How does symmetry enable us to grapple with monstrous
numbers? And how might symmetry contribute to the elusive Theory of
Everything?
