Hurricanes topple plenty of trees, but when you think about it, the more amazing thing is that many trees can stand up to these 100-mile-per-hour winds.
Now a French scientist has come up with an explanation for the resilience of trees. And astonishingly, the answer was first described by Leonardo da Vinci 500 years ago.
Leonardo noticed that when trees branch, smaller branches have a precise, mathematical relationship to the branch from which they sprang. Many people have verified Leonardo's rule, as it's known, but no one had a good explanation for it.

In 2011, Novak Djokovic had just about the best year a male tennis player has ever had, including wins at three of the four Grand Slam tournaments.
"This is the athlete of the year," says Jon Wertheim of Sports Illustrated. "This is a brutal, brutal sport. This guy is playing on six continents, every surface....This is one of the all time great years in open tennis history."
This year, Djokovic also kept to a gluten-free diet. Must have been particularly difficult since his family's business is a pizza parlor.
Harold O'Neal is a jazz pianist with an unusual resume. Born in Tanzania and raised in Kansas City, Miss., O'Neal is also a hip-hop dancer, martial artist and actor. He's just released a new album with an unusual back story of its own: Marvelous Fantasy is a largely improvised collection of solo piano pieces, an homage to the music of silent films.

A few strings of lights and an inflatable Santa are enough for some people when it comes to holiday decorations. But not for the Garabedian family of the Bronx, whose over-the-top Christmas displays have been a traffic-snarling must-see for nearly four decades. And "traditional" is definitely not the right word for this holiday attraction.
The first giveaway might be the music the Garabedians play through speakers outside their home. Instead of a Christmas carol, you're more likely to hear a hit single from a singer like Engelbert Humperdinck.
