This musical genre is named for the grass that grows underfoot in the Eastern U.S. region. But its artistic roots are in Scotland, England, and Ireland, where fiddle music, reels and jigs came from, crossing the Atlantic with immigrants. If you've never seen the accompanying dance style, "Appalachian flatfooting," check out the videos on YouTube. It's worth watching.

The Dow is actually a very small index. To get a better feel for how the American economy is performing, check the Standard & Poor's 500 (commonly abbreviated as "S&P 500"). It's much more reflective, though the Dow steals all the headlines!

We're not sure how many people got their affairs in order and said goodbye to loved ones based solely on the idea that the Mayan calendar didn't extend past the year 2012.

If you got this question right, you might know the story. After a newspaper prematurely printed an obituary for Nobel that criticized him for contributing to modern warfare, he founded the Nobel Prizes so he'd be remembered for something good. It worked out pretty well, wouldn't you say?

This short and sweet rhyming poem is by Robert Frost. Its final refrain is, "For I have promises to keep/And miles to go before I sleep/And miles to go before I sleep." Why repeat the final line, when nothing else in the poem is doubled? That kind of artistic choice is what made the man a great poet!
