In The Eye Of The Beholder
What makes your brain tick?
According to researchers, the parts of your body, if you don't use it you lose
it, particularly your brain. The more you use it, the more logic & brainier you
are. Could that be true?
If colour is in my head, then am I an artist ?
It has been said that 1 in 10 of us cannot see what most people saw in a
painting, and almost all outsiders (autistic) do not see the aesthetic in a
painting, then I've to examine my head.
Research indicated that about 10% of the population, and particular among male,
and about 1% of the population are outsiders (autistic), are having minor forms
of symmetrical coordinates or partial colour deficiencies inherited.
And as in science, the sky we perceived blue depends on the different
frequencies of light (colour) available at the time. The highest frequencies we
can detect with our naked eye appears violet (blue-end), and the lowest
frequencies, many times slower than violet, appears red, and in between these
frequencies (colour) appear 'yellowish-GREEN-bluish' colour -- all together they
appear white to us, the visible spectrum.
Everything we see reflect light rather than absorb, well, absorb a bit of the
colour frequency not got, and reflect all other frequencies (colours) of light
back.
The colours we see are the frequencies of the object's true colour -- thus we
perceive roses are red and their leaves are green.
The sky we perceive it's blue because the red frequency is slower to reach us,
and as the fast ultraviolet frequencies of light, after being more effectively
scattered by our atmosphere -- nitrogen and oxygen molecules, and many other
tiny particles in our ozone layer scattered the ultraviolet light.
Followed by blue, green, yellow, orange, and red in that order; and our eyes are
not sensitive to ultraviolet light, thus blue seems predominate our vision, so
we think the sky is blue.
Our brain is also fast to interpret the lower frequencies being least scattered,
not true also being scattered though less effectively than blue during sun set.
Since the fast ultraviolet frequency has gone over the outer edge of the Earth a
bit, sunset appears red, orange, and yellowish to us.
The true is at sunset light had sunk below the horizon, atmosphere is thinner at
the top, and light travels faster in thin air, which bend the light path to
least-time, giving us longer daylight summer time when the Earth axial rotation
tilted towards northern hemisphere.
Solar frequencies (colours) can best be observed in the rainbow colour spectrum,
if you have notice that yellow-green parts of this spectrum are more intense
than other frequencies.
This is due to the Earth do not evenly distribute all the frequencies of light,
and our eyes-brain had evolved to perceive sensitivity in
'yellowish-green-bluish' frequency ranges, thus at night we see warmth with
yellowish-white sodium-vapour lamp than other the cool bluish-green colour of
lights in winter times; and why more countries have adopted the bright
contrasting yellow-green colour for emergency vehicles, particularly near
airports where visibility is vital.
Electrons close together vibrate in steps, which results in a greater intensity
of scattered light than from the same electrons vibrating separately, thus white
clouds are bright, and we still get sunburn from ultraviolet (UV) radiation in
the cloudy days.
But water is transparent to nearly all visible frequencies of light, and only
absorbs a week infrared waves to resonate near the surface of water, and warms
the water on a hot sunny day, but not any deeper.
The sea looks greenish-blue to us because weakened frequency in water is
cyan-like in colour; greenish-blue absorbs red-light frequency, thus look
greenish-blue to us.
And at night, water actually looks dark even with full moon, only the surface of
the water is shiny, thus don't step in them, you don't know how deep the water
could be.
To survive in the dark, night footmen had this saying in the old days...
dark mud, white stone, shiny water ditch.
Even under bright sunlight, the amplitudes of these vibrations are less than 1%
of the radius of the atomic nucleus; it is these tiny electron vibrations that
re-emit the light by which we see this colourful world.
Things do not emit light yet visible to us because they re-emit light
reaching their surface from a source such as moon light, this light falls on
the surface of materials, and either re-emitted without change in frequency,
or absorb the light-wave for heat or both, depends on the material.
Those absorb and re-emit light where it came from is call reflection, and
those bends light from where it came from is call refraction, such as
transparent materials past light from molecule to molecule which bends them.
So on the surface of all the objects around us, the electron cloud of atoms
undergo slight vibration under the influence of illumination of light. These
tiny vibrations over a wide range of frequencies reflect the various colours
of light by which we see these objects. Simply put, we say that we see these
objects by the light they reflect.
When material appears white actually reveal the fact that the electrons are
set into vibration at all the visible frequencies, very little absorption
occurs. And what appears black is a different story, except for a bit of
reflection; dark material absorbs most of the visible frequencies.
Light will take the most efficient path and travel in a straight line, but if
obstructed by objects, such as a reflective mirror, light will kink its
straight path. And in water, light will deviate its path -- in other word,
light will always take the path require the shortest time, that's the
geodesic effect.
In the eye of the beholder
In the rules of additive mixtures, the same thought cannot apply to
oil paintings as oil pigments are not pure, and cannot be thought of as
visible spectrums.
The secret of applying light in oil paintings is a dab of lemon yellow on
white, plus fine linseed oil. Let the oil dry for a month or two and than
re-apply linseed oil on the painting again, the results could be a museum
piece.
And as we don't have pigeon eyes, even perfect eye-brain coordinated
artists at times have problem with spectral lines, due to our eyes overlapping fields of vision.
Parallax displacement or orientation of viewing any objects is the problem along two
different lines of sight, for our eye and brain to measure the angles of inclination between
lines, thus we know that nearby objects have a larger parallax than more distant one when
observed from different positions.
Hemispheric asymmetries in eye-hand coordination for the handedness, may
post further obstacle.
Although our temporal and spatial accuracy were equal for both left and
right handedness movements, manual asymmetries were found in behavioural and
neuron-physiological data, suggesting an asymmetric mode of control for left
vs. right eye-handedness coordination.
For left eye-hand coordination, peak velocity and saccade completion occurred
earlier than for the contra-lateral movements, suggesting that there may be more
time is needed for homing-in on the target.
And for right eye-hand coordination, there is more activation in our occipital
areas, which might indicate a more intense visual processing or visualization
of the target location.
With impaired vision further affect hand-eye coordination, as well as
cognitive, neurological, and physical development skills for would be
artists.
Knowing a bit about our eye-brain pays dividend, since the rod of our eyes
and the cone cells are interconnected for visual receptors to combine the
information in the retina.
Our eyes do much of the decision making process before passing on to our
brain, and our iris do much of the thinking, the intensity reveals in the
size of our pupils -- card players knew from the pupil of opponent.
Eye-hand Coordinates
It so happen that most of our finger patterns form loops, about 60% of us are, others whorls or
bull's eye, about 35%, and only about 5% of finger patterns are 'arches', these
friction ridges enable our fingers to grip the brush for eye-brain coordinates.
Also bear in mind that in our retina ganglion neurons, where about 50-55% are
the W-cells (one of the three major functional cells), and the smallest of the three functional types, for the directional
movement vision.
And about 40% are the X-cells for high-resolution vision, but only about 5-10% are
the Y-cells, also the largest of the three, for peripheral fields and respond to
fast movement.
Not
sure any links with our genetic evolution between neuron cells and finger
patterns, but almost certain that during cell division and folding as in
gamete-genesis and in zygote stages already determined our finger ridge patterns.
Empirical research on the handedness indicated that almost 90% of us are right-handed, and the rest are left-handed, except the
few are ambidextrous, this might be down to the chirality linkages of helix
directions in our genetic evolutions.
Our asymmetrical brain where the dominant hemisphere
controls language, mathematical, and analytical skills, and the handedness, also
receives sensory signals from the opposite side of our body.
Chemical synapses allow neurons to form circuits within
the central nervous system. They are crucial to the biological computations that
underlie perception and thought, and allow the nervous system to connect to and
control other systems of the body.
Scientists have since identified that proteins act as magnets to attract
nerve cells to each halves of the brain, were responsible for the
two halves development that causes it to become asymmetrical, a property that is
critical in allowing the two hemispheres to specialize and operate more efficiently.
Practicing artists should also bear in mind that we are trichromats (our
vision base on blue, green, and red wavelengths), and genetically, nearly 1 in
10 of us male, and particularly so in the West, are having minor forms of
partial colour deficiencies inherited. And the many outsiders (about 1 in 100),
such as autistic artists showing spectral line anomalies in their drawing or
painting due to eye-brain coordinate difficulties. These innate ideas do
reinforce the links between nature and nurture in the aesthetic of the artist's
work.
Also, if intelligence quotient (IQ) means test bear any scientific
significance, social researchers revealed that socially average intelligent
adult scores below 70 out of 100, 2% of these guys fit into the description of
mentally retarded with cognitive impairments, are unlikely to master the science
of art.
And as we live in a cosmic wave universe with added human induced
electromagnetic radiation, we are submerged in these waves as fish in water,
often made our hair stand on ends or gave us the spark; this electromagnetic is
not static at all to artist.
Also our synaptic brain often over loaded with electrons, affecting our nervous system connection to other controlling
body parts - holding a brush to paint is a science on its own.

Note:
(1) Geodesic effect - light will take the most efficient path when travel in a
straight line.
Light is electromagnetic energy that is emitted in the form of waves. We live
in a turbulent sea of electromagnetic radiation. Like any ocean, this sea has
large waves and small waves, short wavelets and long rollers.
The waves crash into objects and are absorbed, scattered, reflected, and
bent. Because of the nature of electromagnetic waves and their interactions with
the environment, the visual system can extract information about the world.
(2) Chirality linkages of monomers as in DNA sequencing, where the 5' to 3'
end prime is the commutator in the 3' to 5' end mirror symmetry.
(3) Handedness could stem from the two major nerve fibre crossings (or
decussations), where the brainstem which attaches to the spinal cord. The
corticospinal decussation is where chemical synapse neuron signals that provide
the basis for non-neuronal cells (or glands) and voluntary motor functions to
the opposite side of the body.
(4) The patterns on our finger could stem from the binary fission stage of
cell division in the gamete-genesis and in zygote, due to helix nature of DNA
molecule, determine the folding of cells forming the ridges.
(5) Spatial summation is a way of achieving action potential in a neuron
which involves input from multiple cells.
In the eye, a small retinal angle of 10-15 arc, the intensity and area are
inversely variable, 100 quanta on one rod is equal to 1 quantum on 100 rods, due
to the merging of signals of rods onto bipolar, in turn onto ganglion cells.
(6) Cosmic microwave background radiation universe with added human induced
waves since the invention of electricity or mobile phone, we see, hear
more hissing sound or snowy screen anytime we turn the TV or radio on.
And the universe is said to composed of about 4% baryons (quarks in the form
of protons and neutrons, plus other trace elements), about 24%-25% dark matter, and
about 70%-72% dark energy (which about 30% could be baryon matter and putative
dark matter).
