The CSI Effect
In the fall of 2000, CBS introduced a show about a bunch of attractive, stylish crime scene investigators who, using an array of high-tech, sometimes science fiction-y tools, crack cases with ironclad, incontrovertible evidence and then – just as breezily, it seems – nab the bad guys. All within a span of about 42 minutes. The show, of course, was CSI, and before long it had become a veritable...

Brushstrokes across the sky
In 1745, Swiss astronomer Jean-Philippe Loys de Chéseaux discovered a new object in the sky that somewhat resembled the Greek letter “omega.” Or maybe it looked like a swan of sorts. In actuality, it’s a nursery for a multitude of newly born stars. Now known as the Omega Nebula, the 17th member of Charles Messier’s famed catalog has also been called the Swan, the Lobster and the Horseshoe and...
