“Words form the sinew and muscle that hold societies upright, he argued. Consider the Koran, the Bible, the American Constitution, but also letters from fathers to sons, last wills, blessings, curses. Thousands upon thousands of words infused with the full spectrum of emotions fill in the nooks and corners of human life.”

“It's only a two-day hike. But it lasts a lifetime.”

“If you are you, breathe. If you breathe, you talk. If you talk, you ask. If you ask, you think. If you think, you search. If you search, you experience. If you experience, you learn. If you learn, you grow. If you grow, you wish. If you wish, you find. And if you find, you doubt. If you doubt, you question. If you question, you understand and if you understand, you know. If you know, you want to know more. If you want to know, more you are alive.”

“The Lord's Prayer is 66 words, the Gettysburg Address is 286 words, there are 1,322 words in the Declaration of Independance, but the government regulations on the sale of cabbage total 26,911 words.”

“A climate's changes are tough to quantify. Butterflies can help. Entomologists prefer "junk species--" the kind of butterflies too common for most collections-- to keep up with what's going on in the insect's world. They're easy to find and observe. When do something unusual, something's changed in the area.Art Shapiro's team at UC Davis monitors ten local study sites, some since the 1970s. The ubiquitous species are the study's go-tos, helping distinguish between lasting changes (climate warming, habitat loss) and ones that will right themselves (one cold winter, droughts like last year's). Consistency is key; they collect details year after year, no empty data sets between.A few species have disappeared from parts of the study area altogether, probably a lasting change. On the other hand, seemingly big news in 2012 might be just a year's aberration. Two butterflies came back to the city of Davis last year, the umber skipper after 30 years, the woodland skipper after 20-- both likely a result of a dry winter with near-perfect breeding conditions of sunny afternoons and cool nights.”

“There are few other four-letter words that hold us all in as much thrall as love.”

“The formal scientific definition of theory is quite different from the everyday meaning of the word. It refers to a comprehensive explanation of some aspect of nature that is supported by a vast body of evidence.”
