It never does much good to find out why you can't; put your effort into what you can do.

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

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.

For it goes without saying that this great recognition at this time will aid tremendously our efforts to find the necessarily large funds for the next voyage of exploration farther into the depths of the atom.

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.
