Черемуха


В каньоне под горой Зарубкой в Западной пустыне штата Юта.
Quiet and soothing rain drops on the chokecherry bushes.

The hail was almost over. Notch Peak was very picturesque against the cloudy sunset.

Ниши в каньоне под Зарубкой


It was raining. I was sitting in one of those niches happily taking pictures.

ABOUT NOTHING


One of the most surprising recent advances in cosmology is that 75% of the Universe seems to be made of nothing. Charles Lineweaver, What is the Universe Made Of?

Nature abhors a vacuum - and so do we. The idea of a void - of emptiness, nothingness, spaceness, placeness, all such 'lessness' - is at once abhorrent and inconceivable; and yet it haunts us in the strangest, most paradoxical way: 'Nothing is more real than nothing.' ...Nothingness, annihilation, is a reality in this ultimately paradoxical sense. There is, indeed, no space without field; but there are conditions in which the 'field' may be lost - a perceptual-ideal 'Kantian' field which is closely analogous to an Einsteinian field. One's sense ob being is entirely contingent upon, co-extensive with, and contained in such a field. And anything which produces 'fieldness' (or field-defect, or scotoma) is certain to produce a corresponding nothingness. Oliver Sacks, The Oxford Companion to the Mind/The Man Who Mistook His Wife for a Hat. London

We not only believe what we see: to some extent we see what we believe. Richard Gregory, The Intelligent Eye

There is still a deeper message here: Your own body is a phantom, one that your brain has temporarily constructed purely for convenience. V.S. Ramachandran, Phantoms in the Brain

The only possible access we may have to phenomena that transcend human concept and sensory perception is by cultivating states of awareness that themselves transcend language, concepts, and sensory experience. B. Alan Wallace, Choosing Reality: A Buddist View of Physics and the Mind

We shape clay into a pot, but it is the emptiness inside that holds what we want. Tao-te Ching

That "nothing" from which something arose should not... be confused with emptiness of a vacuum. It is nothing in a profound sense. It is nothingness.
John Wheeler, Geons, Black Holes, and Quantum Foam

Real systems are, in this sense, "exciations of the vacuum" - much as surface wavws in a pond are excitations of the pond's water...The vacuum in itself is shapeless, but it may assume specific shapes. In doing so, it becimes a physical reality, a "real world". Henning Genz, Nothingness: The Science of Empty Space

The history of physics is the history of giving up cherished ideas. Space and time are things we've cherished for thounsands of years, and it's clear we-re going to have to give them up. Andrew Strominger

The reality we observe in our laboratories is only an imperfect reflection of a deeper and more beautiful reality, the reality of the equations that display all the symmetries in the theory. Stephen Weinberg, Dreams of a Final Theory

As we explore physics at higher and higher energy, revealing its structure at shorter and shorter distances, we discover more and more symmetry. David Gross, The Role of Symmetry in Fundamental Physics

We must be able to answer the question What is time? as simply and clearly as we answer the question What is heat? Alexander Polyakov, Princeton University, String Theory at the Millenium, Caltech

Nothing is too wonderful to be true. Michael Faraday

If the universe hadn't been suitable for our existence, we wouldn't be asking why it is the way it is. Stephen Hawking
