Robbie Robertson
Canadian Musician
I am fascinated by the places that music comes from, like fife-and-drum blues from southern Mississippi or Cajun music out of Lafayette, Louisiana, shape-note singing, old harp singing from the mountains - I love that stuff. It's like the beginning of rock and roll: something comes down from the hills, and something comes up from the delta.
Quote examples
Gregory Benford
American Physicist
In coastal waters rich in runoff, plankton can swarm densely, a million in a drop of water. They color the sea brown and green where deltas form from big rivers, or cities dump their sewage. Tiny yet hugely important, plankton govern how well the sea harvests the sun's bounty, and so are the foundation of the ocean's food chain.

John M. Grunsfeld
American Astronaut
All indications are that three and a half billion years ago, Mars looked like Earth. It had lakes. It had rivers. It had river deltas. It had snow-capped peaks and puffy clouds and blue sky. Three and a half billion years ago, it was a happening place. The same time on Earth, that's when life started. So did life start on Mars?
