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.

We have reached the age, those of us to whom fortune has assigned a post in life's struggle, when beaten and smashed and biffed by the lashing of the dragon's tail, we begin to appreciate that the old man was not such a fool after all. We saw our parents wrestling with the same dragon, and we thought, though we never spoke a thought aloud, 'Why doesn't he hit him on the head?' Alas, comrads, we know now. We have hit the dragon on the head and we have seen the dragon smile.

From the beginning of the Radiation Laboratory, I have had the rare good fortune of being in the center of a group of men of high ability, enthusiastic and completely devoted to scientific pursuits.

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.

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.

Oh, somewhere in this favoured land the sun is shining bright; The band is playing somewhere; and somewhere hearts are light; And somewhere men are laughing; and little children shout; But there is no joy in Mudville- great Casey has struck out.
