The fact that Science walks forward on two feet, namely theory and experiment, is nowhere better illustrated than in the two fields for slight contributions to which you have done me the great honour of awarding the the Nobel Prize in Physics for the year 1923. Sometimes it is one foot that is put forward first, sometimes the other, but continuous progress is only made by the use of both-by theorizing and then testing, or by finding new relations in the process of experimenting and then bringing the theoretical foot up and pushing it on beyond, and so on in unending alterations.

The pathetic thing about it is that many scientists are trying to prove the doctrine of evolution, which no science can do.

There is no likelihood that man can ever tap the power of the atom

There is no likelihood man can ever tap the power of the atom. The glib supposition of utilizing atomic energy when our coal has run out is a completely unscientific Utopian dream, a childish bug-a-boo. Nature has introduced a few fool-proof devices into the great majority of elements that constitute the bulk of the world, and they have no energy to give up in the process of disintegration.

Interest and attention will insure to you an education.

Religion and science, then, in my analysis are the two great sister forces which have pulled, and are still pulling, mankind onward and upward.

Fullness of knowledge always and necessarily means some understanding of the depths of our ignorance, and that is always conducive to both humility and reverence.
