We must not forget that when radium was discovered no one knew that it would prove useful in hospitals. The work was one of pure science. And this is a proof that scientific work must not be considered from the point of view of the direct usefulness of it. It must be done for itself, for the beauty of science, and then there is always the chance that a scientific discovery may become like the radium a benefit for mankind. ”
"When you make a choice and say, 'Come hell or high water, I am going to be this,' then you should not be surprised when you are that. It should not be something that is intoxicating or out of character because you have seen this moment for so long that ... when that moment comes, of course it is here because it has been here the whole time, because it has been [in your mind] the whole time."
