atoms

At the atomic level, matter does not even exist with certainty; it only exists as a tendency to exist.

Chess is a game with simple rules and pieces, a small sixty-four-space board, but there are more possible chess games than there are atoms in the universe.

This world and everything in it is only temporary; eternity is out there, we swim in it. And within our temporary bodies we carry inside of us eternity. There are but atoms separating us from the everlasting. Merely atoms.

When we look at a solid lump of iron or rock, we are 'really' looking at what is almost entirely empty space. It looks and feels solid and opaque because our sensory systems and brains find it convenient to treat it as solid and opaque. It is convenient for the brain to represent a rock as solid because we can't walk through it. 'Solid' is our way of experiencing things that we can't walk through or fall throug, because of the electromagnetic forces between atoms. 'Opaque' is the experience we have when light bounces off the surface of an object, and none of it goes through.

Also unlike a planet, an electron__f excited by heat or light__an leap from its low-energy shell to an empty, high-energy shell. The electron cannot stay in the high-energy state for long, so it soon crashes back down. But this isn__ a simple back-and-forth motion, because as it crashes, the electron jettisons energy by emitting light.

Every atom in your body spins and danceslike a bee around the queen,like a whirling dervish,like the stars spiraling in a galaxy.Yet why do you sit motionlessly watching Dancing With the Stars?

When you do the math and examine how much energy is produced per atomic union, you find that fusing anything to iron__ twenty-six protons costs energy. That means post-ferric fusion* does an energy-hungry star no good. Iron is the final peal of a star__ natural life.

Consider now the Milky Way. Here also we see an innumerable dust, only the grains of this dust are no longer atoms but stars; these grains also move with great velocities, they act at a distance one upon another, but this action is so slight at great distances that their trajectories are rectilineal; nevertheless, from time to time, two of them may come near enough together to be deviated from their course, like a comet that passed too close to Jupiter. In a word, in the eyes of a giant, to whom our Suns were what our atoms are to us, the Milky Way would only look like a bubble of gas.

The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.

The air around you is filled with floating atoms, sliding down the Earth's spacetime curve. Atoms first assembled in the cores of long-dead stars. Atoms within you, everywhere, disintegrating in radioactive decays. Beneath your feet, the floor - whose electrons refuse to let yours pass, thus making you able to stand and walk and run. Earth, your planet, a lump of matter made out of the three quantum fields known to mankind, held together by gravity, the so-called fourth force (even though it isn't a force), floating within and through spacetime.

A writer observes. A writer records for posterity. The moments in the transience of the labyrinth of time that would go unrecorded otherwise! A writer records for value. A writer records for sentimentalism. A writer tries in earnest to carry the emotions and sentiments that make us what we ultimately are. For what are we? Empty spaces in an atom!

I think that we were both the same star in the beginning of the universe and as the star exploded we drew apart. Our atoms merging into two different bodies, but over time our atoms found a way and found each other again.

After our negotiations were completed, the dome would be imploded and launched toward the nearest black hole, so that none of its atoms would ever contaminate this particular universe again. I thought that last part was overkill.

Nothing is forever. Except atoms.

Originally, the atoms of carbon from which we__e made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life__he carbohydrates, amino acids, proteins, and lipids__s by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

[Think] of an experience from your childhood. Something you remember clearly, something you can see, feel, maybe even smell, as if you were really there. After all you really were there at the time, weren't you? How else could you remember it? But here is the bombshell: you weren't there. Not a single atom that is in your body today was there when that event took place. Every bit of you has been replaced many times over (which is why you eat, of course). You are not even the same shape as you were then. The point is that you are like a cloud: something that persists over long periods, while simultaneously being in flux. Matter flows from place to place and momentarily comes together to be you. Whatever you are, therefore, you are not the stuff of which you are made. If that does not make the hair stand up on the back of your neck, read it again until it does, because it is important.

I have tried to read philosophers of all ages and have found many illuminating ideas but no steady progress toward deeper knowledge and understanding. Science, however, gives me the feeling of steady progress: I am convinced that theoretical physics is actual philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics), and it has taught us new methods of thinking (complementarity) which are applicable far beyond physics.

[About describing atomic models in the language of classical physics:]We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.
