...dips in the middle, the way coffee does when it is stirred in a cup. In perfect deference to the laws of physics, the metal's highly reflective surface takes the form of a parabola, the shape of solid mirrors used in conventional telescopes to focus starlight into a sharp image. Says Ermanno Borra, the Laval astrophysicist who built it: "It's a wonderfully simple arrangement...
...pauses before biting into a muffin. "I really shouldn't," he says during a day of campaigning in Scotland. "I'm fat."

Post is turned out in corporate splendor--a sharp, dark gray suit. His tone is impassioned, as urgent as a preacher's. His message: Etiquette builds better relationships. Boiled down, he says, Biz Et has three aims: "Think before acting, make choices that build relationships, and do it sincerely." The well-tailored young business crowd pays rapt attention.
