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.

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.

One of the chief inhibitions to human progress arises because of the extreme slowness with which the advances in knowledge become translated into action for the benefit of society as a whole. There is no step more important for the removal of that inhibition than that of providing for intimate contact between the leaders in the fields of pure and applied science.

Civilization consists in the multiplication and refinement of human wants.

Willard Gibbs did for statistical mechanics and for thermodynamics what Laplace did for celestial mechanics and Maxwell did for electrodynamics, namely, made his field a well-nigh finished theoretical structure.

Science walks forward on two feet, namely theory and experiment. Sometimes it is one foot which is put forward first, sometimes the other, but continuous progress is only made by the use of both.
