Becoming a Southern Lady, An Essay

She felt like an outsider who didn’t fit in with Southern ladies—that is until, after studying us, she finally figured us out. “All you have to do,” she told me, “is say two things: ‘How’s yo’ momma?’ and ‘Love yo’ hair’.”

Welcome to the Quietest Square Inch in the U.S.

The quietest inch isn’t a sound vacuum. It represents a place with a minimum of human-made noise. The discipline of acoustic ecology, which is dedicated to understanding the natural sounds that come through loud and clear when we're not around, outlines an important distinction between sound and noise.  The blip of water droplets from a forest canopy? Sound. The tinny din of Taylor Swift through smartphone speakers? Noise.

Cooling is as important to civilization as making fire — only much harder

Chilled, Tom Jackson’s enthralling history of how refrigeration changed the world, takes us from Mesopotamian ice-houses to the Large Hadron Collider  It’s a fascinating journey and Jackson conducts it in the manner of a wizard. From heat-pumps we whisk in a flash to 18th-century BC Terqa, on the west bank of the Euphrates, where the new king Zimri-lim sets about building an ice-house. We race, shivering and sweltering by turns, around the ancient world, to fifth-century BC Persia, to Egypt, from stone jars in water-pits to ceramic pots standing in kraters of snow (and, incidentally, giving sense to the naming of sorbet). Cold — colder than it should be — is always, in this narrative, as magical as Kubla Khan’s ‘sunny pleasure-dome with caves of ice’
