“In a gas, motion has the upper hand; the atoms are moving so fast that...” — William Henry Bragg Quote

“In a gas, motion has the upper hand; the atoms are moving so fast that they have no time to enter into any sort of combination with each other: occasionally, atom must meet atom and, so to speak, each hold out vain hands to the other, but the pace is too great and, in a moment, they are far away from each other again.”

“The chemist, whose science is immediately concerned with the combinations of atoms, has rarely found it necessary to discuss their shapes, and gives them no particular forms in his diagrams. That does not mean that the shapes are unimportant, but rather that the older methods could not define them.”

“When a liquid boils, the temperature has been raised to such a pitch that the evaporating molecules are sufficient in number and speed to lift off the air from the surface of the liquid and push it back en masse.”

“The atoms may be compared to the letters of the alphabet, which can be put together into innumerable ways to form words. So the atoms are combined in equal variety to form what are called molecules.”

“The infinite variety in the properties of the solid materials we find in the world is really the expression of the infinite variety of the ways in which the atoms and molecules can be tied together, and of the strength of those ties.”

“I was having a conversation with my father and he was talking about this thing - strangeness and charm. It's actually the name of the two smallest particles that there are when you split the atom, so I wrote a song around it. I even managed to fit the word 'hydrogen' in there. Isn't that a nice thing for scientists to call them though?”

“Seven decades after it was struck by an atom bomb, Hiroshima is a city of peace and hope.”

“The savages don't have atom bombs.”

“In the lab, we could not see or physically describe the mathematical objects that we called quarks, which we suspected were the key to unlocking the dynamics of the strong force that binds together the clump of protons and neutrons at the center of the atom.”

“When passion has wrecked the body in one life, it is stamped upon the seed atom. In the next descent to rebirth, it is therefore impossible for him to gather sound material with which to build a brain of stable construction.”
