To do easily what is difficult for others is the mark of talent. To do what is impossible for talent is the mark of genius. – Henri Frederic Amiel

I think this is the most extraordinary collection of talent, of human knowledge, that has ever been gathered together at the White House, with the possible exception of when Thomas Jefferson dined alone. – John F. Kennedy, in an address to Nobel Prize winners

Geniuses are the luckiest of mortals because what they must do is the same as what they most want to do. – W. H. Auden
