Color Bridge

"I believe I have already suggested that color is the most obvious bridge between emotion and perception, that is, between subjective experience of the psyche and quality objective in nature. Both light up only between the extremes of light and darkness, and in their reciprocal interplay. Thus, outward the rainbow - or, if you prefer it, the spectrum - is the bridge between dark and light, but inwardly the rainbow is, what the soul itself is, the bridge between body and spirit, between earth and heaven."

- Owen Barfield (1898 - 1997)

Everything is Flowing

"...everything is flowing—going somewhere,
animals and so-called lifeless
rocks as well as water."

- John Muir (1838 - 1914)

Light, Shadow, Time

"Our job is to record, each in his own way,
this world of light and shadow and time
that will never come again exactly
as it is today."

- Edward Abbey (1927 - 1989)

Nature's Mirror

"In this secluded spot the soothing silence,
Far from the clank of crowds, I stand or sit, musing,
Thoughts that are the hymns of the praise of things,
Largely learn’d from nature’s schooling.
Give me again O nature your primal sanities!
Thou hast, O nature! elements!
Utterance to my heart beyond the rest.
...
Somehow I feel the globe itself swift-swimming in space.
I merge myself in the scene, in the perfect day,
Never before did I get so close to nature—
absolute and unqualified acceptance of nature—
Never before did she come so close to me.
...
The mirror that nature holds is deep and floating
and ethereal and faithful, I see
my soul reflected in nature."

- Walt Whitman (1819 - 1892)
"The Poet in Nature"

The Intuitive Mind

"The difference between the mathematical and the intuitive mind.—In the one the principles are palpable, but removed from ordinary use; so that for want of habit it is difficult to turn one's mind in that direction: but if one turns it thither ever so little, one sees the principles fully, and one must have a quite inaccurate mind who reasons wrongly from principles so plain that it is almost impossible they should escape notice ... But in the intuitive mind the principles are found in common use, and are before the eyes of everybody. One has only to look, and no effort is necessary; it is only a question of good eyesight, but it must be good, for the principles are so subtle and so numerous, that it is almost impossible but that some escape notice.

...

All mathematicians would then be intuitive if they had clear sight, for they do not reason incorrectly from principles known to them; and intuitive minds would be mathematical if they could turn their eyes to the principles of mathematics to which they are unused. The reason, therefore, that some intuitive minds are not mathematical is that they cannot at all turn their attention to the principles of mathematics. But the reason that mathematicians are not intuitive is that they do not see what is before them, and that, accustomed to the exact and plain principles of mathematics, and not reasoning till they have well inspected and arranged their principles, they are lost in matters of intuition where the principles do not allow of such arrangement. 

...

They are scarcely seen; they are felt rather than seen; there is the greatest difficulty in making them felt by those who do not of themselves perceive them. These principles are so fine and so numerous that a very delicate and very clear sense is needed to perceive them, and to judge rightly and justly when they are perceived, without for the most part being able to demonstrate them in order as in mathematics; because the principles are not known to us in the same way, and because it would be an endless matter to undertake it. We must see the matter at once, at one glance, and not by a process of reasoning."

.- Blaise Pascal (1623 - 1662)

Sand Dunes in the Desert

"Every ripple on the ocean,
every leaf on every tree,
every sand dune in the desert,
every power we never see."

- Sting (1951 - )

"Our Intellect Ingulphs Itself so Far"

"The glory of Him who moveth everything
  Doth penetrate the universe, and shine
  In one part more and in another less.
...
Within that heaven which most his light receives
  Was I, and things beheld which to repeat
  Nor knows, nor can, who from above descends;
...
Because in drawing near to its desire
Our intellect ingulphs itself so far,
That after it the memory cannot go."

- Dante Alighieri (1265 - 1321)

Self-Organized Criticality

"Who could ever calculate the path of a molecule?
How do we know that the creations of worlds are
not determined by falling grains of sand?"

- Victor Hugo (1802 - 1885), Les Miserables 

"How can the universe start with a few types of elementary particles at the big bang, and end up with life, history, economics, and literature? The question is screaming out to be answered bur it is seldom even asked. Why did the big bang not form a simple gas of particles, or condense into one big crystal? We see complex phenomena around us so often that we rake them for granted without looking for further explanation. In fact, until recently very little scientific effort was devoted to understanding why nature is complex.

I will argue that complex behavior in nature reflects the tendency of large systems with many components to evolve into a poised, "critical" state, way out of balance, where minor disturbances may lead to events, called avalanches, of all sizes. Most of the changes take place through catastrophic events rather than by following a smooth gradual path. The evolution to this very delicate state occurs without design from any outside agent. The state is established solely because of the dynamical interactions among individual elements of the system: the critical state is self-organized. Self-organized criticality is so far the only known general mechanism to generate complexity. 

To make this less abstract, consider the scenario of a child at the beach letting sand trickle down to form a pile. In the beginning, the pile is flat, and the individual grains remain close to where they land. Their motion can be understood in terms of their physical properties. As the process continues, the pile becomes steeper, and there will be little sand slides. As time goes on, the sand slides become bigger and bigger. Eventually, some of the sand slides may even span all or most of the pile. At that point, the system is far out of balance, and its behavior can no longer be understood in terms of the behavior of the individual grains. The avalanches form a dynamic of their own, which can be understood only from a holistic description of the properties of the entire pile rather than from a reductionist description of individual grains: the sandpile is a complex system.

The complex phenomena observed everywhere indicate that nature operates at the self-organized critical state. The behavior of the critical sandpile mimics several phenomena observed across many sciences, which are associated with complexity."

How Nature Works

There is Light

 "Wherever there is light, one can photograph.
...
I have a vision of life, and I
try to find equivalents for it in
the form of photographs.
...
In photography there is a reality so subtle
that it becomes more real than reality."

- Alfred Stieglitz (1864 - 1946)

White Hole

"Unless something goes in or out of the horizon,
from the outside a white hole is
indistinguishable from a black hole.
...
The black horizon, like Gandalf,
has magically turned white.
...
Despite the complete difference between
what happens inside them, time’s
sleight of hand on the horizons allows a
white hole and a black hole to be
the same thing outside.
...
A white hole is a black hole with time reversed.
...
...finite are the lives of us all, of
every living organism, every star,
every galaxy, of all stories,
in this universe of joy and pain.
Not even white holes last forever."
