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.

Niels Bohr 

In his first meeting with Werner Heisenberg in early summer 1920, in response to questions on the nature of language, as reported in Discussions about Language (1933); quoted in Defense Implications of International Indeterminacy (1972) by Robert J. Pranger, p. 11, and Theorizing Modernism : Essays in Critical Theory (1993) by Steve Giles, p. 28

The atoms come into my brain, dance a dance, and then go out — there are always new atoms, but always doing the same dance, remembering what the dance was yesterday.

Quote in context:

“For instance, the scientific article may say, “The radioactive phosphorus content of the cerebrum of the rat decreases to one-half in a period of two weeks.” Now what does that mean? It means that the phosphorus that is in the brain of a rat — and also in mine, and yours — is not the same phosphorus as it was two weeks ago. It means the atoms that are in the brain are being replaced: the ones that were there before have gone away. So what is this mind of ours: what are these atoms with consciousness? Last week’s potatoes! They now can remember what was going on in my mind a year ago — a mind which has long ago been replaced. To note that the thing I call my individuality is only a pattern or dance, that is what it means when one discovers how long it takes for the atoms of the brain to be replaced by other atoms. The atoms come into my brain, dance a dance, and then go out — there are always new atoms, but always doing the same dance, remembering what the dance was yesterday.”

For every atom belonging to me as good belongs to you.

Quote in context: 

I CELEBRATE myself, and sing myself,

And what I assume you shall assume,

For every atom belonging to me as good belongs to you.”

— Walt Whitman, “Song of Myself,”  Leaves of Grass (1891)

Did you know that the phrase “and sing myself” didn’t appear in the 1855 version?

“First direct observation of the orbital structure of an excited hydrogen atom”!
