There is not enough space in the universe to write down the number googolplex. But can you write down a googol?


There are numbers so ridiculously huge that there just is not enough space in the universe to write them down. What's even more amazing, is that these astronomically large numbers are actually of utmost importance, and even crucial, for understanding the world.

The two largest meaningful numbers are the googol (which has since become world famous in the form of Google) and the googolplex. The googol got its name from a nine year old nephew of mathematician Edward Kasner. He asked his nephews for any ideas they might have to name a really big number, and that is what nine year old Milton Sirotta came up with.

Kasner decided that 10^100—or, the number one followed by one hundred zeroes—would henceforth be known as a googol. Young Milton suggested an even larger number, the googolplex. He said it must be a number 1 followed by as many zeroes as could be written down before one gets tired.

Kasner felt it needed a better definition. It would be 10^googol, or 1 followed by a googol of zeroes. Therefore, a googolplex is 10^10^100. Carl Sagan once pointed out that it would physically impossible to write down all the zeroes in a googolplex, because there simply isn't enough room in the universe!

Americans eat a dramatically higher amount of sugar than they did 200 years ago! Find out how much!


Processed foods, supermarkets, and fast food have revolutionized the way Americans get that tasty, bad-for-you sugar into their bodies. In fact, the amount of sugar Americans consume every five days now is about the same that they consumed in a year just 200 years ago.

Sugar is the most popular ingredient added to foods in the United States. It's added to everything from sweets to processed foods to "healthy" things like peanut butter. The biggest culprit of sugar in the American diet? Soft drinks. A single teaspoon of corn syrup adds up to 20 calories.

The average American ate 2 pounds of sugar a year back in the early 1800s. That is increased to 123 pounds of sugar a year in 1970. Today? 152 pounds of the sweet stuff. That's the same as eating 3 pounds of sugar a week!

Nutritionists suggest only 10 percent of American's diets should come from sugar. Based on a 2,000 calories a day diet, that's only about 13.3 teaspoons a day. That is dwarfed by the reality of a whopping 42.5 teaspoons a day for the average American. Next time you ask for sugar in your coffee, maybe you should think twice!

Chances are, queen ants will outlive your pets! Find out how long they live


It's a little depressing to think that a tiny bug will outlive most of your pets, but the Queen ant has a life span up to 30 years. They have the longest life span of any known insect. In fact, German Entomologist Hermann Appel held a queen of Lasius niger in captivity for 28.75 years.

Queen ants are the primary reproducing ant in a colony, usually being the mother to all other ants in the colony. They come from larvae that is specially fed 'royal jelly' to become sexually mature. Some species only need a single mother queen while others may have hundreds of fertile queens to create an overcrowded colony.

Once a colony is established, the queen ant lays eggs continuously. She picks and chooses which eggs to fertilize by using sperm cells retained from nuptial flight, which is a phase in the ant's life that consists of mating then moving on to start new colonies.

Despite being the queen, she has very little control over what the colony does. Her role has nothing to do with making decisions or commanding authority, she simply keeps reproducing. However, she is waited on hand and foot, being provided with food and having her waste disposed so she doesn't need to move. Talk about room service!

Some awesome lists!

A 'jiffy' is an actual unit of time, but it means different things across various fields of study


The term "jiffy" is often used to describe a very short but unspecified period of time, for example: "I'll have it sorted out in a jiffy!" The exact origin of the word is unclear, but it was first attested in 1785.

Gilbert Newton Lewis (1875–1946) proposed a unit of time called the "jiffy" which was equal to the time it takes light to travel one centimeter (approximately 33.3564 picoseconds). Since then, it has been redefined and used for different measurements in different fields of study.

In electronics, a jiffy is the time between alternating current power cycles (1/60 or 1/50 of a second). In computing, a jiffy was originally the time between two ticks of the system timer interrupt. The term "jiffy" is sometimes used in computer animation as a method of defining playback rate, with the delay interval between individual frames specified in 1/100th-of-a-second (10 ms) jiffies.

In astrophysics and quantum physics a jiffy (as defined by Edward R. Harrison) is, the time it takes for light to travel one fermi, which is approximately the size of a nucleon. One fermi is10−15 m, so a jiffy is about 3 × 10−24 seconds. Informally it has been defined as "one light-foot," which works out as approximately one nanosecond.

A human bite may be more dangerous than an animal bite. Find out why!


The wilderness is full of untold dangers that lurk in the forests, lakes, and mountains. Creatures big and small pose huge threats and we're all scared of one thing: Their mouths!

Turns out, the real mouth you should be worried about is your next-door neighbor's.

Humans will bite, or at least come in contact with another human's teeth, for a ton of different reasons. Fists come into contact with teeth in a fight, or an unruly child will take a chomp out of someone's arm when they let their guard down. If the bite breaks the skin it has an incredible risk of infection.

In fact, human bites are often more dangerous than most animal bites due to the germs some human mouths carry that cause infections that are extremely difficult to treat. Surgery, or at least a heavy helping of antibiotics is common on an infected human bite.

While you may brush off a bite from a toddler, try to treat it as if it were a venomous snake bite. Seek medical aid as soon as possible, especially if it's bleeding, and don't get the wound anywhere near your mouth. If swelling, redness, puss, or pain appear, get to a doctor immediately.
