Is the human eye fully grown at birth?

When born, we're bald and toothless. Sadly, many of us die looking the same way. In fact, I've heard the eye is the only body part that remains the same size from birth until death. However, after doing a little research, I discovered this is more rumor than fact.

According to several sites, a typical newborn's eye is around 18 millimeters in diameter. When you are an infant, the size increases to 19.5 millimeters. A fully grown adult's eye measures 24-25 millimeters. In Fact at this is point it is worth pointing out that a fully developed eyeball is about two-thirds the size of a ping-pong ball.

This means a human eye grows only about 28% over the course of its life. Fish supposedly have the ability to increase their eye size "steadily over the course of their entire lives," a talent lost on us "superior" Homo sapiens.

If Hillary Clinton is elected president what would we call Bill Clinton?

The United States has never had a female president, so I had never grappled with this bit of etiquette. Or, to put it another way, there's no precedent for that president.

That said, our first female president will be referred to as "Madam President." This is how female heads of state are referred to in other countries. I can only assume the same rules will apply here. Addressing the president's husband (if she's married) is a bit trickier.

If Hillary Clinton were elected president, we'd most likely still refer to Bill Clinton as either "Mr. President" or "former President Clinton." Even after they're out of office, past commanders in chief retain the title. Call it a perk of the job.

Of course, not every potential presidential candidate is married to a previous ruler of the free world. For example, if Britney Spears were elected to the office (God help us), we'd all address Kevin Federline as "First Gentleman." This is how Dan Mulhern, the spouse of the governor of Michigan, is referred to. Same thing with Jose Miguel Tuason Arroyo, husband of Philippine president Gloria Macapagal-Arroyo.

How many cars are in the world?

Besides having negative effects on our planet, the seemingly excessive number of cars makes parking an unwelcome challenge. Maybe it's time to donate my Ford and start taking the bus.

I love finding one page with all the answers, and the Physics Factbook has just such a page. The stats begin in 1900, when somewhere between 4,142 and 8000 passenger cars existed in the United States (the only country to manufacture cars at that time). In 1985, there were 375 million passenger cars and 109 million commercial vehicles worldwide. Just 85 short years resulted in 6 million percent growth. Not too shabby.

A 1997 report claimed that in that year, over 600 million motor vehicles existed in the world. It went on to predict that if the existing trends continued, that number would double in the next 30 years. So in 2030, we could see 1.2 billion cars. And we thought parking was bad now.

How does the human brain measure up to a computer?

At the risk of ticking off computers everywhere, we believe the human brain could hold more data than any hard drive currently available. Here's why...

Although it's tempting to think of computers as infallible and able to do more in a millisecond than we can do in a day, that's a bit of a misconception. Human beings take a lot of their cognitive abilities for granted. For example, according to a study from MIT, simulating basic actions in robots, like talking, laughing, and walking, requires an amazing amount of memory and processing power.

On the other hand, maybe that's not a fair comparison. After all, in many ways, hard drives are superior to the human brain. As the University of Washington points out, when it comes to multitasking, computers have near limitless potential. As for people, even the smartest of us sometimes have a hard time patting our stomachs and rubbing our heads at the same time.

Do wild animals ever get overweight or obese?

Food is hard to come by in the wild, so rarely will an animal will have the opportunity to overfeed. Occasional access to extra nutrition generally results in a benefit to the next generation, by either the production of more young or a size advantage in the competition for mates.

Some wild animals, especially those that hibernate, put on additional weight in the fall that they can use for energy in the winter. They conserve that energy during the colder months by decreasing activity. The American black bear begins to prepare for hibernation in the summer, and can gain as much as 30 pounds per week. It then loses about half its total weight while wintering-over.

Usually when there's an imbalance between activity spent hunting or foraging and amount of food intake, humans are involved. Captive and domesticated animals can be more prone to a sedentary lifestyle, in which they don't need to expend much energy for their meals. Even animals closer to human populations might behave differently than those in the wilderness.

Who came up with the idea of putting paper umbrellas in cocktails?

Nobody really knows who invented the cocktail umbrella, but that doesn't mean we can't waste a few minutes kicking around some theories.

An amusing article from Metroactive suggests the umbrella may have originated at a famed Bay Area bar named Trader Vic's.

The Straight Dope's digging provided more clues. According to Peter Seely, grandson of the founder, "never in its history had Trader Vic's served a drink with a cocktail umbrella." However the founder's son contradicts this, saying Trader Vic's did indeed serve cocktails with umbrellas until the early 1940s.

While the folks at Trader Vic's may have made the paper umbrella what it is today, they didn't come up with the original idea. According to several sources, Vic's "borrowed" the decoration from a chap named Don the Beachcomber.

Don, Vic, whatever. The real question is, where did these guys get the umbrellas? They didn't make 'em themselves, did they? Though there's no definitive evidence, many believe the umbrellas were a Chinese American invention, possibly designed to shield ice cubes from the sun.

Whoever it was, he or she can take pride in the fact their invention is a part of every mai tai and just as important as the rum. Cheers to that.
