Science can give mankind a better standard of living, better health and a better mental life, if mankind in turn gives science the sympathy and support so essential to its progress.

If scientific reasoning were limited to the logical processes of arithmetic, we should not get very far in our understanding of the physical world

Science has a simple faith, which transcends utility. Nearly all men of science, all men of learning for that matter, and men of simple ways too, have it in some form and in some degree. It is the faith that it is the privilege of man to learn to understand, and that this is his mission. If we abandon that mission under stress we shall abandon it forever, for stress will not cease. Knowledge for the sake of understanding, not merely to prevail, that is the essence of our being. None can define its limits, or set its ultimate boundaries.

Science can give mankind a better standard of living, better health and a better mental life, if mankind in turn gives science the sympathy and support so essential to its progress.

There has been a great deal said about a 3,00-mile high-angle rocket. The people who have been writing these things that annoy me, have been talking about a 3,000-mile high-angle rocket shot from one continent to another, carrying an atomic bomb and so directed as to be a precise weapon which would land exactly on a certain target, such as a city.

The question of whether a device will come into being depends upon three things: first, whether there is a practical use for it that warrants its development and manufacturing costs; second, whether the laws of physics applying to the elements available for its design allow the attainment of the needed ranges, sensitivities, or the like; and third, whether the pertinent art of manufacture has advanced sufficiently to allow a useful embodiment to be built successfully.

Science has a simple faith, which transcends utility... It is the faith that it is the privilege of man to learn to understand, and that this is his mission.
