The day when the scientist, no matter how devoted, may make significant progress alone and without material help is past. This fact is most self-evident in our work. Instead of an attic with a few test tubes, bits of wire and odds and ends, the attack on the atomic nucleus has required the development and construction of great instruments on an engineering scale.

In the Radiation Laboratory we count it a privilege to do everything we can to assist our medical colleagues in the application of these new tools to the problems of human suffering.

Let us cherish the hope that the day is not far distant when we will be in the midst of this next adventure.

The day when the scientist, no matter how devoted, may make significant progress alone and without material help is past. This fact is most self-evident in our work.

No individual is alone responsible for a single stepping stone along the path of progress, and where the path is smooth progress is most rapid.

The atomic bombs will surely shorten the war, and let us hope that they will effectively end war as a possibility in human affairs.

I am mindful that scientific achievement is rooted in the past, is cultivated to full stature by many contemporaries and flourishes only in favorable environment. No individual is alone responsible for a single stepping stone along the path of progress, and where the path is smooth progress is most rapid. In my own work this has been particularly true.
