Step aside John, James, Mary, and Jane—the most popular name in the world is believed to be Muhammad. According to the Independent, an estimated 150 million men and boys around the world share this name. The popularity is thanks to a Muslim tradition of naming each first-born son after the Islamic prophet.

Not everyone lives in a booming city or sprawling suburb. Many people still make their homes outside of bustling locations—especially in India, which has the largest number of people living in rural areas (approximately 893 million people live outside of the city), according to Reuters. China also has an impressively large rural population, with 578 million living outside of major centers.

The 1933 Double Eagle was a $20 U.S. coin made of gold that never went into circulation. A few of the coins were made, but most were destroyed—save for nine that were presumed stolen by U.S. mint workers. After years circulating the globe and falling into the hands of a few notable owners—including the king of Egypt—one of the coins was auctioned off at Sotheby's in 2002 for a stunning $7,590,020. That made it the most expensive coin ever sold at auction.

Due to overfishing and disease, the oyster population in Maryland's Chesapeake Bay was seriously suffering. But thanks to dedicated work by scientists at the Horn Point Laboratory, the Army Corps, the National Oceanic and Atmospheric Administration, and the Nature Conservancy, the state is now the location of the world's largest man-made oyster reef. Home to more than one billion oysters, the area is a no-fishing zone, which will hopefully give the population a chance to recover.

There are more than 24 time zones around the world.

f the Earth's time zones were each one hour apart, then we would have 24 times zones, which sounds pretty straightforward. However, the situation is a little more complicated than that. Since many time zones only differ by 30 or 45 minutes, they don't fit into a neat and tidy 24 hour span, which means that there are more than 24, though it's hard to say exactly how many.
