Quote of the Day for 2015-08-11


"The whole secret of the study of nature lies in learning how to use one's eyes."

George Sand (1804-1876) Letter to Juliette Lambert-Adam, April 7, 1868

Translation: Which animals are most like each other? – Rabbit and Duck. Uncredited illustration from Fliegende Blätter, issue #2645 (October 23, 1892). "What were ducks in the scientist's world before the revolution are rabbits afterwards." – Thomas Kuhn (1922-1996) The Structure of Scientific Revolutions, chapter 10. The image is a hand-drawn optical illusion. Look at it one way and it appears to be the head of a duck. Another way and the duck's bill becomes rabbit ears and suddenly it becomes a bunny.
