Your chemistry high school teacher lied to you when they told you that there was such a thing as a vacuum, that you could take space and move every particle out of it.

God in the beginning formed matter in solid, massy, hard, impenetrable, movable particles, of such sizes and figures, and with such other properties, and in such proportion to space, as most conduced to the end for which he formed them.

Empty space is a boiling, bubbling brew of virtual particles that pop in and out of existence in a time scale so short that you can't even measure them.

The main ingredient of the first quantum revolution, wave-particle duality, has led to inventions such as the transistor and the laser that are at the root of the information society.

My smile has been my ticket to the world. Smiling releases the same feel-good hormones you get jogging. Caring for your lips and gums is important. I brush my teeth morning and night, alternating toothpaste brands. In addition to flossing, I use a Water Pik to massage my gums and remove food particles.

Neutrinos alone, among all the known particles, have ethereal properties that are striking and romantic enough both to have inspired a poem by John Updike and to have sent teams of scientists deep underground for 50 years to build huge science-fiction-like contraptions to unravel their mysteries.

There never was one particle of... jealousy... in the heart of Hyrum Smith.

Happiness is a sunbeam which may pass through a thousand bosoms without losing a particle of its original ray; nay, when it strikes on a kindred heart, like the converged light on a mirror, it reflects itself with redoubled brightness. It is not perfected till it is shared.

In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace.

In the far, far future, essentially all matter will have returned to energy. But because of the enormous expansion of space, this energy will be spread so thinly that it will hardly ever convert back to even the lightest particles of matter. Instead, a faint mist of light will fall for eternity through an ever colder and quieter cosmos.

Things on a very small scale behave like nothing that you have any direct experience about. They do not behave like waves, they do not behave like particles, they do not behave like clouds, or billiard balls, or weights on springs, or like anything that you have ever seen.

Experience is never limited, and it is never complete; it is an immense sensibility, a kind of huge spider-web of the finest silken threads suspended in the chamber of consciousness, and catching every air-borne particle in its tissue.

Elon Musk is talking about silicon nanoparticles pulsing through our veins to make us sort of semi-cyborg computers. But why not take a noninvasive approach? I've been working and trying to think and invent a way to do this for a number of years and finally happened upon it and left Facebook to do it.

JUST AS EVERY PARTICLE OF NATURE IS USEFUL, SO SHOULD EVERY MOMENT OF YOUR LIFE BE USEFUL TO YOU AND TO OTHERS.

We say that a human being is a person and a distinctive, fixed self with a name and a life. He has an identity. But what is this self really made of, except from the basic elements such as hydrogen, carbon, oxygen, phosphorus etc. and their subatomic particles? If a person is a specific, static, unchanged entity and existence, then what if an accident or a disease completely alters his body features? What if fear or madness changes his thoughts and perceptions? If dementia takes away his memories, or if drugs alter his emotions? And what if life circumstances, good or bad luck, modify his motives, his plans and his desires? Is it still the person we say he is? Or is selfhood a ghost, a useful fiction of the brain? An ever-shifting kaleidoscope of thoughts, feelings and perceptions? Flashes of hopes and desires? A bundle of alternating opinions and ideologies, of conflicting instincts and urges? If we take away all these from him, what would be left behind? If every drop of the ocean evaporates, is not the whole ocean gone? The immutable selfhood is a very old illusion and the last of illusions we 're going to abandon; if we ever will?

Which came first - the observer or the particle?

I like to work in watercolor, with as little under-drawing as I can get away with. I like the unpredictability of a medium which is affected as much by humidity, gravity, the way that heavier particles in the wash settle into the undulations of the paper surface, as by whatever I wish to do with it. In other mediums you have more control, you are responsible for every mark on the page - but with watercolor you are in a dialogue with the paint, it responds to you and you respond to it in turn. Printmaking is also like this, it has an unpredictable element. This encourages an intuitive response, a spontaneity which allows magic to happen on the page. When I begin an illustration, I usually work up from small sketches - which indicate in a simple way something of the atmosphere or dynamics of an illustration; then I do drawings on a larger scale supported by studies from models - usually friends - if figures play a large part in the picture. When I've reached a stage where the drawing looks good enough I'll transfer it to watercolor paper, but I like to leave as much unresolved as possible before starting to put on washes. This allows for an interaction with the medium itself, a dialogue between me and the paint. Otherwise it is too much like painting by number, or a one-sided conversation.

"Every particle of dust on a patch of earth

If the giddiness of life and the pressure of time might make us tumble from our tight line, let us inhale the wisdom of our Inspirational and reshape our "inner void" into an "inner space" and refurbish it with the fundamental, vital particles of our everyday experience. ("One drink after work.")

We seem to inhabit a universe made up of a small number of elements-particles-bits that swirl in chaotic clouds, occasionally clustering together in geometrically logical temporary configurations.

When we say two bodies 'touch', what we mean (without knowing it) is that both electromagnetic fields are interacting to avoid physical interpenetration and ... that happens well before subatomic particles touch!

"Electrons, when they were first discovered, behaved exactly like particles or bullets, very simply. Further research showed, from electron diffraction experiments for example, that they behaved like waves. As time went on there was a growing confusion about how these things really behaved ---- waves or particles, particles or waves? Everything looked like both.

"Imagination is not, as some poets have thought, simply synonymous with good. It may be either good or evil. As long as art remained primarily mimetic, the evil which imagination could do was limited by nature. Again, as long as it was treated as an amusement, the evil which it could do was limited in scope. But in an age when the connection between imagination and figuration is beginning to be dimly realized, when the fact of the directionally creator relation is beginning to break through into consciousness, both the good and the evil latent in the working of imagination begin to appear unlimited. We have seen in the Romantic movement an instance of the way in which the making of images may react upon the collective representations. It is a fairly rudimentary instance, but even so it has already gone beyond the dreams and responses of a leisured few. The economic and social structure of Switzerland is noticeably affected by its tourist industry, and that is due only in part to increased facilities of travel. It is due not less to the condition that (whatever may be said about their 'particles') the mountains which twentieth-century man sees are not the mountains which eighteenth-century man saw.

?In modern physics, there is no such thing as "nothing." Even in a perfect vacuum, pairs of virtual particles are constantly being created and destroyed. The existence of these particles is no mathematical fiction. Though they cannot be directly observed, the effects they create are quite real. The assumption that they exist leads to predictions that have been confirmed by experiment to a high degree of accuracy.
