Einstein thought in pictures

Logic will take you from A to B. Imagination will take you everywhere.
Einstein

"Einstein thought in curious pictures, then in fictional "thought experiments," then got some math and a Laputan raft of scientists to do the experiments. That we can work back from some imaginings and thought experiments to mathematics and physical experiments might be the most important thing we do as a species. Before anything can be done, it must first be imagined howerever imperfectly. In a sea of photons the waves can be as long as a universe."
George Zebrowski, "After the Stars are Gone." From the book Year Million: Science at the Edge of Knowledge.
