William Broad

William Broad talks about yoga, a practice thousands of years old. His book The Science of Yoga describes what’s uplifting and beneficial about the practice of yoga and what’s flaky and even dangerous. He looks at the burgeoning global yoga industry, which attracts true believers and charismatic hustlers.

We talked yesterday with David Sanger, who writes for our partner The New York Times, about the very disturbing notion that North Korea has already become a nuclear power, and the possibility that Pyonyang could sell nuclear materials to enemy nations, or even terrorists. Sanger wrote his article with his colleague William Broad, who has another article in the Times today about whether Americans would know what to do in order to try and survive a nuclear bomb attack.
