But the fact that some geniuses were laughed at does not imply that all who are laughed at are geniuses. They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown.
— Carl Edward Sagan (American astronomer, astrophysicist, cosmologist, author, science popularizer and science communicator, 1934 – 1996)
