Why does thunder rumble? Acoustic professor Trevor Cox explains that it has to do with the way lightning is a jagged line. "Each little kink is actually generating the sound, and the reason thunder rumbles is because the sound takes different time to come from different kinks because they're all slightly different distances from you," he says.
Ever wonder why your voice sounds so much better when you sing in the shower? It has to do with an acoustic "blur" called reverberation. From classical to pop music, reverberation "makes music sound nicer," acoustic engineer Trevor Cox tells Fresh Air's Terry Gross. It helps blend the sound, "but you don't want too much," he warns.
Teen years are sort of a "rehearsal" for adulthood, author Meg Wolitzer tells Fresh Air's Terry Gross, and that's particularly true at the performing arts summer camp where her latest novel begins. It's 1974, and the main character, Jules, a newcomer to the camp, is invited into a circle of 15- and 16-year-olds who nickname themselves — with knowing irony — The Interestings.
Opening nights of new incarnations of late-night TV talk shows are good, mostly, for first impressions — or, in the case of Jay Leno, sometimes a second impression. It's not fair to make strong judgments on the content alone, because a first show always is top-heavy with ideas, special guests and nervousness. But it is fair game to judge the set, the environment, the overall mood, and how well the host fits into the history of late-night television.
For the past 37 years, Robert Caro has devoted his life to writing the definitive biography of Lyndon Johnson. So far, The Years of Lyndon Johnson has four acclaimed volumes and has shown readers just how complex the 36th president was, as both a politician and a man.

Every year, students come into my office and say, "I don't know what I want to do with my life." Of course, plenty of people in the world don't have the luxury of such cluelessness, but my students don't look like they're enjoying their privilege; they look scared and depressed, as though they've already failed some big test of character. They might find some comfort in Michael Sims' new biography of the young Henry David Thoreau called, simply, The Adventures of Henry Thoreau.
