A Reassuring Fable

Modern science has been a voyage into the unknown with a lesson in humility waiting at every stop. Our common sense intuitions can be mistaken, our preferences don’t count. We do not live in a privileged reference frame. If we crave some cosmic purpose, then let us find ourselves a worthy goal.

What exactly is happening when you pick up a knife, or push a swing, or make a wave in a waterbed by pressing down on it periodically? When we investigate deeply, we find that there is no physical contact. Instead, the electric charges on your hand are influencing the electrical charges on the knife or swing or waterbed, and vise versa. Despite everyday experience and common sense, even here, there is only the interaction of electric fields. Nothing is touching anything.

An extraterrestrial being newly arrived on Earth - scrutinizing what we mainly present to our children in television, radio, movies, newspapers, magazines, the comics, and many books - might easily conclude that we are intent on teaching them murder, rape, cruelty, superstition, credulity, and consumerism. We keep at it, and through constant repetition many of them finally get it. What kind of society could we create if, instead, we drummed into them science and a sense of hope?

Books, purchasable at low cost, permit us to interrogate the past with high accuracy; to tap the wisdom of our species; to understand the point of view of others, and not just in power; to contemplate - with the best teachers - the insights, painfully extracted from Nature, of the greatest minds that ever were, drawn from the entire planet and from all from all of our history. They allow people long dead to talk inside our heads. Books can accompany us everywhere. Books are patient where we are slow to understand, allow us to go over the hard parts as many times as we wish, and are never critical of our lapses. Books are key to understanding the world and participating in a democratic society.

We detect the light from distant quasars only because the laws of electromagnetism are the same ten billion light-years away as here. The spectra of those quasars are recogonizable only because the same chemical elements are present there as here, and because the same laws of quantum mechanics apply. The motion of galaxies aroud one another follows familiar Newtonian gravity. Gravitational lenses and binary pulsar slow-downs reveal general relativity in the depths of space. We could have lived in a Universe with different laws in every province, but we do not. This fact cannot but elicit feelings of reverence and awe.
