A googol number is a large numeral represented by a 1 followed by 100 zeros.

## Take a closer look now

A googol number is a numeral represented by a 1 followed by 100 zeros. The concept of a googol was invented by mathematician Edward Kasner in the 1930s, who asked his young nephew Milton Sirotta to come up with a name for the extremely large number. Sirotta reportedly replied, “Why don’t you call it a googol?” The term has since entered popular culture, and even inspired the name of the world’s largest search engine, Google.

Here are some interesting facts about googol numbers:

- A googol is larger than the number of atoms in the observable universe.
- It would take over 10^90 times the age of the universe to count to a googol.
- A googolplex is an even larger number than a googol, represented by a 1 followed by a googol of zeros.
- The symbol for a googol can be represented as 10^100, or as the shorthand “1e100” in scientific notation.
- In mathematics, a googol is used as an example of a really big number, but it is rarely used in practical calculations.
- The concept of a googol inspired other large number names, such as googolplexian and googolduplex.
- In the animated series “Phineas and Ferb,” the title characters build a rollercoaster with a duration that lasts one “ferbtillion” googolplexes.

As Kasner himself put it, a googol is “a number which we, who are beyond a mere physical counting of the sands of time, know to be exceedingly, even incomprehensibly vast.”

The video “How Big is a Googol?” attempts to provide a visualization of the enormity of a googol by comparing it to the size of our observable universe. Even a line of pollen specks stretching to the Andromeda Galaxy falls short of a googol by 70 orders of magnitude. By converting the width of each speck into volume and filling the observable universe with pollen specks, a total of 4 x 10^95 specks is obtained, still short of a googol by a factor of 100,000 visible universes.

Google is the word that is more common to us now, and so it is sometimes mistakenly used as a noun to refer to the number

10 100. That number is a googol, so named by Milton Sirotta, the nephew of the American mathematician Edward Kasner, who was working with large numbers like 10 100.

A googol is the large number

10100. In decimal notation, it is written as the digit 1 followed by one hundred zeroes: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.

In 1920, Edward Kasner ‘s nine-year-old nephew, Milton Sirotta, coined the term googol, which is

10 100, and then proposed the further term googolplex to be "one, followed by writing zeroes until you get tired".

## Interesting facts on the topic

**Interesting:**A googol is such a large number that our minds can’t even comprehend it, and because it’s so large it doesn’t have a particularly important role in mathematics. It’s even estimated that there are only 4 x 1079 atoms in the universe, which is less than a googol.

**Did you know that,**Googol is also called "ten duotrigintillion" on the short scale, "ten thousand sexdecillion" on the long scale, and "ten sexdecilliard" on the Peletier long scale. A googolplex is a mathematical number 10 googol, or equivalent to . It is written as 1 followed by 10 100 zeros; in simple words, it is 1 followed by googol zeros.

**Interesting:**Googol is a quantity that surpasses even the number of hydrogen atoms in the observable universe, is a number dating back to the mid 1900s and is still used by mathematicians today. This drawing from Yumi, a 7 years old girl gave me the idea for this article. A googol is the large number 10100.

## I am confident you will be intrigued

A googol is 10 to the 100th power, which is 1 followed by 100 zeros. While this is an unimaginably large number, there’s still an infinite quantity of larger numbers.

Written out in ordinary decimal notation, it is 1 followed by 10100 zeroes; that is, a 1 followed by a googol of zeroes.

It’s impossible to write out, but in scientific notation it looks like 1 x 1010^100.
