"Consider the discovery of the electron. Could anything at first sight seem more impractical than a body which could only exist in vessels from which all but a minute fraction of the air had been extracted - which is so small that its mass is an insignificant fraction of the mass of an atom of hydrogen - which itself is so small that a cloud of these atoms equal in number to the population of the whole world would be too small to have been detected by any means then known to science ? Now the electron has come into commerce and large workshops and many thousands of workers are employed in its production. It has hardly an exaggeration, I think, to say that any new scientific discovery contains the germ of a new industry. But I think these instances, which I have given, show that scientific discoveries are very efficient means of creating employment. And instead of attempting to reduce unemployment by reducing research, at some level suggested, I think the best hope for a durable cure is to . . . go in for more and more research. In my opinion, it is in laboratories more often than houses of parliament that a cure will be found." J.J. Thomson
