The promise of a smooth career, which my first calm introduction toThornfield Hall seemed to pledge, was not belied on a longer acquaintance with the place and its inmates. Mrs. Fairfax turned out to be what she appeared, a placid-tempered, kind-natured woman,
of competent education and average intelligence. My pupil was a lively child, who had been spoilt and indulged, and therefore was sometimes wayward;
I have heard it asserted by some, that as America hath flourished under her former connection with Great Britain, that the same connection is necessary towards her future happiness, and will always have the same effect. Nothing can be more fallacious than this kind of argument. We may as well assert, that because a child has thrived upon milk, that it is never to have meat; or that the first twenty years of our lives is to become a precedent for the next twenty.
We all know that cities are great engines of innovation. One reason that's the case, as Emily Badger recently pointed out, is that cities grow "superlinearly": interpersonal connections grow at an greater rate than sheer population, and with that super proximity comes a super exchange of ideas. The secrets of industry, as economist Alfred Marshall once wrote, are truly "in the air."
Every year, billions of tons of rock and soil vanish from Earth’s surface, scoured from mountains and plains and swept away by wind, rain, and other elements. The chief driver of this dramatic resurfacing is climate, according to a new study. And when the global temperature falls, erosion kicks into overdrive.
Scientists have long debated what drives most of the world’s erosion: Is it predominantly triggered by climate, or is it the result of mountain-building, tectonic activity? Most previous studies of erosion have relied on measuring the amounts of sediment that accumulate somewhere after being carried away from their sources and deposited elsewhere. But such analyses focus on the aftereffects of erosion, not the process itself, says Frédéric Herman, a geophysicist at the University of Lausanne in Switzerland. And most research has looked at limited regions of Earth—a particular mountain range, say, and not the planet as a whole.
