There's an article by three British scientists in the scientific journal Physical Review Letters that says, in part: A general continuum theory for the distribution of hairs in a bundle is developed treating individual fibers as elastic filaments with random intrinsic curvatures, applying this formalism to the iconic problem of the ponytail. The iconic problems of the ponytail? Where's the problem? Who better to explain than our math guy, Keith Devlin of Stanford University?
Many lives are being turned completely upside down by the eurozone crisis. That's especially true in Ireland, where they're still clearing up the mess left when the property bubble burst. Thousands of homes lie empty and unsold. And as NPR's Philip Reeves reports, some people have been left with colossal debts.
PHILIP REEVES, BYLINE: Step, for a minute, into the strange world of Jill Godsil. She lives among the farms and villages and rolling hills of Ireland's Wicklow County. The countryside's spectacular.
As Phil reported, things are still pretty tough for the people of Ireland, but there's one man who thinks things there will start to look up before too long. He's prepared to put money on it, billions in fact.
Michael Hasenstab is what's known as a contrarian investor. He's just about the only person prepared to bet that Ireland's fortunes will greatly improve over the next couple of years. Michael Hasenstab joins us from Templeton Investments in San Mateo, California.

The latest research, however, shows that people with GEDs are, in fact, no better off than dropouts when it comes to their chances of getting a good job.
This is raising lots of questions, especially in school districts with high dropout rates and rising GED enrollments.
