Do you have any idea of the kind of balls it took to be a part of this team? Under intense time pressure to work with previously theoretical isotopes that just might save tens of thousands of American lives?
And you judge them? You, with the heat on, comfortable, probably overly fed.
What. A. Putz. You. Are.
Nuclear isotopes were treated with quite a degree of reckleness for a good many years. Also I don't think they were any more heroic then anyone else who assisted with the war effort, although unlike many they were establishing for themselves quite a lucrative career. The men working in coal mines to supply energy to head up the war effort we far more heroic then a bunch of scientists getting paid handsome salarys to do what they like to do anyways, ground breaking science.
