"But some numbers, called dimensionless numbers, have the same numerical value no matter what units of measurement are chosen. Probably the most famous of these is the 'fine-structure constant,' .... Physicists love this number not just because it is dimensionless, but also because it is a combination of three fundamental constants of nature."

"Some of the natural world is appealing, some of it is terrifying, and some of it grosses us out. Modern people don't want to be dropped naked into a swamp. We want to tour Yosemite with our water bottles and G.P.S. Devices. The natural world is a source of happiness and fulfillment, but only when prescribed in the right doses."
