Theodosius Dobzhansky Quote
Great ideas often seem simple and self-evident, but only after somebody has explained them to us. Then, how interesting they become! The act of insight is among the most exciting and pleasurable experiences a scientist can have, when he recognizes what all the time was there to be seen, and yet he did not see it.
