" In human manufacturing, use of interchangeable parts was a revolutionary innovation, and hard work to achieve. How did Nature achieve it? How could uniformity, if achieved by careful adjustment, stand up to the ravages of time? And if the building blocks are supremely stable, and resistant to change, how did they arise in the first place?

Maxwell was alert to , and intrigued by, this issue, seeing in it evidence of benevolent Creation. As he put it:

'Natural causes, as we know, are at work, which tend to modify, if they do not at length destroy, all the dimensions of the earth and the whole solar system. But though in the course of ages catastrophes have occurred and may yet occur in the heavens, though ancient systems may be dissolved and new systems evolved out of their ruins, the molecules out of which these systems are built-the foundation stones of the material universe-remain unbroken and unworn.

They continue this day as they were created-perfect in number and measure and weight, and form the innefaceable characters impressed on them we may learn that those aspirations after accuracy in measurement, truth in statement, and justice in action, which we reckon among our noblest attributes as men, are ours because they are essential constituents of the image of Him who in the beginning created, not only the heaven and the earth, but the materials which heaven and earth consist. "
