Rosalyn Yalow -- On Eureka moments.

"If you ever have a new idea, and it’s really new, you have to expect that it won’t be widely accepted immediately. It is a long, hard process. Till my dying day I will remember Greer Garson and Walter Pidgeon, in the film Marie Curie, coming back to the laboratory at night and seeing the glowing that meant they had discovered radioactivity. That was exciting! They knew they had it, but it was the culmination of a long process of blood, sweat, and tears. It was followed by a good deal more blood, sweat and tears. You don’t suddenly come out of your bath and say “Eureka!” Science is only in part like that." Rosalyn Yalow -- Particular Passions: Talks With Women Who Shaped Our Times, by Lynn Gilbert.
