Rhythms Which are Seen and Unseen

4.8

The rhythms of the wind can be felt and even heard. But there are many rhythms that we cannot hear or see, but which we can draw or measure.

In chemistry there are tiny particles called molecules, too small for the eye to see. They move in a definite rhythm in liquids or gases, but we cannot see them.

In electronics (electronics is the science of the movement of electromagnetic waves), if the radar waves moving through space could be seen, they would look like this.

The rhythms of electronics were a mystery to men a hundred years ago. But now we know that light and sound and the atom in its orbit, each moves in its own rhythm.

So, in this wonderful world there are rhythms that men can see, like those of sea waves. And there are unseen rhythms that we cannot see, but which we can measure by scientific instruments. Many mysteries about these unseen forces remain to be solved.
