Failures of the imagination

The quote below is from the eminent British scientist Lord Kelvin, who also pronounced that x-rays were a hoax, that heavier than air flying machines would never catch on and that radio had no future…

I often say that when you can measure what you are speaking about, and express it in numbers, then you know something about it; but when you cannot measure it, when you cannot express it in numbers, your may knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever that may be.

Lord Kelvin, 1891

I’d turn that statement about and remark that once you have a number in your grasp, your problems have only just started. And that numbers shorn of context are a meagre and entirely unsatisfactory way of expressing our understanding of the world.

When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.

Arthur C. Clarke,  Profiles of the Future (1962)

I often think that Arthur C. Clarke penned his famous laws in direct juxtaposition to the dogmatic statements of Lord Kelvin. It’s nice to think so anyway. 🙂
