Enthusiastic book recommendations! Martha's savoring the biography of Alexander von Humboldt, the 19th-century explorer, polymath, and naturalist who revolutionized our understanding of nature and predicted the effects of human activity on climate. Grant's enjoying A Brief History of Everyone Who Ever Lived, about how the study of DNA is rewriting our understanding of history itself. And a customer is startled when a salesperson waves goodbye with a friendly Preesh! Is Preesh really a word you might use to say you appreciate someone's business? Plus, where would you hunt for a tizzy? All that, and whang, sloomy, abbiocco, receipt vs. recipe, scorn vs. scone, the language of emotions, poronkusema, a brain-tickling puzzle about the letter P, and the story behind the unit of distance called a smoot.
