The science of energy allows us to perceive the divine force that sustains the universe. There is a force we call electromagnetism.

It cannot be grasped with any of the five senses—we can know it only from its effects and related phenomena. Indeed, we cannot explain it in any other terms.

Yet it permeates all of our experience, and from it we derive great light and power.

It manifests itself in the pull of a magnet, in the light of the sun, in the waves that carry our network of communication through air and empty space, in the work performed by our machines, and in endless more phenomenon.

Yet it is one.

For its Creator is one.
