Thirty spokes converge upon a single hub;
It is on the hole in the center that the use of
the cart hinges.
We make a vessel from a lump of clay;
It is the empty space within the vessel that
makes it useful.
We make doors and windows for a room;
But it is these empty spaces that make the
room livable.
Thus, while the tangible has advantages,
It is the intangible that makes it useful.

asymmetry and life
The term chiral (once again) is used to describe an object that is non-superimposable on its mirror image. amongst others, there are mathematical, physical, and biochemical implications of chirality. within itself--a particular molecule can be symmetrical when cut through a certain plane, while another molecule has no such plane. between two molecules--two mirror images of a molecule that cannot be superimposed onto each other are referred to as enantiomers or optical isomers.
chirality, is a subtle mystery of nature, more fundamental then asymmetry (something chiral can still have rotational symmetry). but asymmetry is interesting in in of its self.
how did asymmetry come to be in nature? there is a deep connection here to the origin of life. ("...life is asymmetric.") what initially caused something asymmetrical to form?

"So far as we can tell, the earth and the universe are, as near as makes no difference, uniform, symmetric environments and there can have been no sophisticated chemistry proceeding during the early stages of evolution. And yet life is asymmetric. The process we are seeking to understand must take a symmetric world and from it create asymmetric life. Somehow, the earth's initial symmetry must be broken to create asymmetric life forms.
"Other theories posit that the chirality of biological chemistry arose prior to the emergence of life, either in outer space or on the earth. Supporters of space as an origin for chirality point to meteorite observations...
"Some observers look for an earthly explanation for asymmetry; for example, the earth's spin and magnetic field together create an asymmetric system that might produce chiral chemical effects. However, experiments indicate that such effects would be minimal. They also note that some rocks are asymmetric....
"Physically, at least, the human brain seems to be a symmetrical organ, with two, apparently identical, hemispheres. However, when in use, our brains exhibit a widely described asymmetry of operation, exemplified [by the way our right hand is controlled with the left hemisphere of the brain]."

she's got a website entitled : Obsessive Consumption: What did I buy today?
(ha, 'n I added her as a facebook friend:)
my depressing post; art v. the power of the "PEN"
(the thread is said to represent the interrelationships of different California populations affected by the prison system; ('n each 6-inch thread represents 10 people)
on exhibition at the Intersection for the Arts
the exhibition features work by inmates incarcerated in the California prison system--alongside artists on the outside, friends and family members--'n artists who just wanna give insight into how imprisonment affects everybody.
