“If, in some cataclysm, all of scientific knowledge were to be destroyed, and only
one sentence passed on to the next generations of creatures, what statement would
contain the most information in the fewest words? I believe it is the atomic
hypothesis (or the atomic fact, or whatever you wish to call it) that all things are
made of atoms—little particles that move around in perpetual motion, attracting
each other when they are a little distance apart, but repelling upon being squeezed
into one another. In that one sentence, you will see, there is an enormous amount
of information about the world, if just a little imagination and thinking are applied.”
