What is Googol ?
A googol is a large number equal to (i.e., a 1 with 100 zeros following it). Written out explicitly,
The term was invented by Milton Sirotta, the 9-year nephew of mathematician Edward Kasner, who had asked his nephew what he thought such a large number should be called. Such a number, Milton apparently replied after a short thought, could only be called something as silly as a “googol.”
What is Googolplex ?
Later, another mathematician devised the term googolplex for 10 to the power of googol – that is, 1 followed by 10 to the power of 100 zeros. Frank Pilhofer has determined that, given Moore’s Law (which is that computer processor power doubles about every 1 to 2 years), it would make no sense to try to print out a googolplex for another 524 years – since all earlier attempts to print a googolplex out would be overtaken by the faster processor.
Googol Vs Google
Larry Page and Sergey Brin, the founders of Google, named their search engine after the term googol. In 1997, Larry was brainstorming names with other Stanford graduate students, including Sean Anderson, and looking at available domain names. Anderson miskeyed googol as “google” and found it available. Larry liked it and the name “Google” stuck. Google’s corporate headquarters is called the GooglePlex, an affectionately tongue-in-cheek reference to the origins of the company name.
How big is actually Googol And Googolplex ?
How big is a googolplex, exactly? Well, we barely have enough time to even attempt to help you visualize it. It’s enormous. So enormous, in fact, that there are more zeroes in a googolplex than there are particles in the observable universe. A common estimate of the number of particles in the observable universe is 10 to the power of 80-less than a googol, and less than the number of zeroes in a googolplex. (Admittedly, this estimate does not include photons and dark matter.) Carl Sagan once said that writing out googolplex would be impossible, because the known universe simply doesn’t have enough space. So, yeah, like we said—enormous.
