Atoms Quote by Erwin Schrodinger

“Why are atoms so small? ... Many examples have been devised to bring this fact home to an audience, none of them more impressive than the one used by Lord Kelvin: Suppose that you could mark the molecules in a glass of water, then pour the contents of the glass into the ocean and stir the latter…” quote by Erwin Schrodinger

“Why are atoms so small? ... Many examples have been devised to bring this fact home to an audience, none of them more impressive than the one used by Lord Kelvin: Suppose that you could mark the molecules in a glass of water, then pour the contents of the glass into the ocean and stir the latter thoroughly so as to distribute the marked molecules uniformly throughout the seven seas; if you then took a glass of water anywhere out of the ocean, you would find in it about a hundred of your marked molecules.”

Erwin Schrodinger

About This Quote

Source Book: “What Is Life?” (1944)

Even tiny molecules disperse uniformly when mixed, illustrating how individual parts become indistinguishable in a vast system.

In simple terms: Molecules spread out evenly in large volumes.
