**Google** is named after **Googol**, which is the digit 1 followed by one hundred zeros (in decimal representation).

The term was coined in 1920 by nine-year-old

Milton Sirotta, nephew of American mathematicianEdward Kasner. Kasner popularized the concept in his book Mathematics and the Imagination.

A googol is of the same order of magnitude as the factorial of 70 (70! being approximately 1.198 googol, or 10 to the power 100.0784), and its only prime factors are 2 and 5 (100 of each). In binary it would take up 333 bits.

The googol is of no particular significance in mathematics, but is useful when comparing with other incredibly large quantities such as the number of subatomic particles in the visible universe or the number of possible chess games. Kasner created it to illustrate the difference between an unimaginably large number and infinity, and in this role it is sometimes used in teaching mathematics. Indeed, it is not even a round figure. Its formal name is tenduotrigintillion.

**Let's analyze Google:**

**Google**'s buildings are numbered **0**, **1**, ** e**,

**π**, and Φ(phi); all of which have mathematical significance.

**IPO**raised $2,718,281,828, which is the product of "

**" and $1 billion, where "**

*e***e**" is the base of the

**natural logarithm**.

For their second public offering Google will sell 14,159,265 shares, which is the first 8 digits after the decimal point in

**π**= 3.14159265....

**Google **played with numbers to select and attract mathematicians, as **Google** loves numbers. There were the numbers again: **π** and ** e**.

** Now let's analyze Google colors:**

You probably see **Google** logo at least once a day, but you certainly don't remember the colors. Anyway, take a closer look at the **Google** logo:

They neither decided which colors to pick nor just a random pick, so **Google** will not do anything random or without a reason. And the colors don't appear random. When we take a closer look at the colors and play around you'll see the earlier mentioned favorite number "** e**" again.

The colors of the logo are

**b**lue

**r**ed

**y**ellow

**b**lue

**g**reen

**r**ed. So that makes

**b**

**r**

**y**

**b**

**g**

**r**. Seems meaningless, but let's get it going on in

**b**

**r**

**y**

**b**

**g**

**r**=

**2**18 25 2

**7 18**

**2718**looks familiar, and it's nothing more than the mentioned number "

*again!*

**e**"The colors may explain in **Google**-style how they did come from googol(plex) to **Google**. The only thing we have to do is solve it.
