“The world is blue at its edges and in its depths. This blue is the light that got lost. Light at the blue end of the spectrum does not travel the whole distance from the sun to us. It disperses among the molecules of the air, it scatters in water. Water is colorless, shallow water appears to be the color of whatever lies underneath it, but deep water is full of this scattered light, the purer the water the deeper the blue. The sky is blue for the same reason, but the blue at the horizon, the blue of land that seems to be dissolving into the sky, is a deeper, dreamier, melancholy blue, the blue at the farthest reaches of the places where you see for miles, the blue of distance. This light that does not touch us, does not travel the whole distance, the light that gets lost, gives us the beauty of the world, so much of which is in the color blue.”—
“The real problem with people fussing over Pluto all the time is it represents the priorities of the public - preserving traditions rather than accepting facts. The pursuit of science is about building a sustainable catalog of truths, and there is no advantage in altering truths to appease nostalgia.”—
“When we try to pick out anything by itself we find that it is bound fast by a thousand invisible cords that cannot be broken, to everything in the universe.”—John Muir - conservationist, naturalist, founder of the Sierra Club, and champion of protected wilderness.
