“Most physicists enjoy the outdoors. They are mushroom gatherers, bird watchers, hikers, amateur mountaineers whose idea of weekend relaxation is to climb a mountain. Several physics summer schools and research centers are located in or near mountainous areas. I have not seen such uniform recreational impulses in other professions, an observation which prompts speculation on the connection between the nature of inquiry in physics and mountain climbing.”

“Climb the mountains and get their good tidings.”

“Any road followed precisely to its end leads precisely nowhere. Climb the mountain just a little bit to test that it's a mountain. From the top of the mountain, you cannot see the mountain.”
