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

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.

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.

I have suggested that scientific progress requires a favorable environment.

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.

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

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.
