A googol is a large number that is equal to 10 raised to the power of 100, or 1 followed by 100 zeros. The term was coined in 1938 by mathematician Edward Kasner’s nine-year-old nephew, Milton Sirotta. While not technically a technology term, it did inspire the name of the search engine Google, which signifies the company’s mission to provide a vast amount of information.


The phonetic transcription of the keyword “Googol” in the International Phonetic Alphabet (IPA) is /ˈɡuːɡəl/.

Key Takeaways

  1. A googol is a large number, represented as 1 followed by 100 zeros, and often used to demonstrate the concept of extremely large quantities.
  2. The term “googol” was coined by the nine-year-old nephew of mathematician Edward Kasner, who needed a name for a number larger than any that had been previously defined.
  3. Googol is not related to Google, the tech company, but the name “Google” was inspired by the concept of a googol to reflect the company’s mission to organize the massive amount of information on the web.


The term “Googol” is significant in the field of technology as it represents an incredibly large number (1 followed by 100 zeros) and symbolizes the vast potential of information processing and retrieval.

The term gained prominence when it inspired the name of the ubiquitous search engine, Google, which aims to organize and provide access to the seemingly limitless amount of information available on the internet.

By choosing a modified version of this term, Google’s founders highlighted their mission to develop innovative search algorithms and tools to help people navigate the ever-expanding digital universe effectively and efficiently.


A googol is an immense number, often used as a representation for quantifying incredibly large quantities or comparing vast probabilities. Coined by mathematician Edward Kasner in the early 20th century, the term “googol” refers to the numeral 1 followed by 100 zeros, or equivalently, it is 10 raised to the power of 100.

Googol’s purpose is primarily to illustrate the concept of extremely large numbers, by providing context and examples for understanding their scale. By grasping the magnitude of a googol, one can better comprehend the vastness and range of values in complex mathematical principles, such as infinity, exponential growth, and combinatorics.

While a googol is not used directly in calculations or daily applications, it provides an invaluable tool for highlighting the tremendous differences between colossal and relatively smaller numbers. For example, it is often utilized when considering the probabilities involved in various scientific phenomena, like the occurrences of particles in the universe or in quantum physics.

The concept of googol may also serve as a rhetorical device that assists in explaining the nuances of big data analysis, cryptography, and estimations of astronomical events. By harnessing the power of this extreme number, scientists, mathematicians, and educators can effectively communicate the enormous scale of the subjects they study and contribute to a broader understanding of our complex world.

Examples of Googol

It seems you are referring to “Google” instead of “Googol”. A Googol is a large number (10^100), while Google is a technology company. Here are three real-world examples related to Google’s technology:

Google Search Engine: Google’s primary product is its search engine, which processes billions of search queries every day. It uses algorithms and artificial intelligence (AI) to analyze and rank web pages, providing users with the most relevant and useful information for their search queries.

Google Maps: Google Maps is a web mapping service offering satellite imagery, aerial photography, street maps, 360° panoramic views of streets (Street View), real-time traffic conditions, and route planning. It helps users navigate and explore the world around them, find places, and get directions.

Google Assistant: Google Assistant is an AI-based virtual assistant that can engage in two-way conversations with users, offering assistance in multiple languages. It can answer questions, send messages, make appointments, control smart home devices, and provide personalized recommendations based on individual preferences. It is available on smartphones, smart speakers, and other compatible devices.

Googol FAQ

What is a googol?

A googol is a very large number equal to 10 to the power of 100, or 1 followed by 100 zeros. It was coined by mathematician Edward Kasner’s nephew, Milton Sirotta, in 1938.

How do you write a googol?

A googol is written as 1, followed by 100 zeros. Here’s what it looks like: 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.

How big is a googol?

A googol is an extremely large number and is often used to illustrate the concept of infinity or an unimaginably large quantity. While it’s difficult to compare this number to anything in the real world, it is far greater than the number of atoms in the observable universe.

What’s the significance of a googol?

The concept of a googol was introduced to help people understand the difference between an extremely large number and infinity. It has been used in various contexts to illustrate the point, such as in probability theory, combinatorics, and popular culture.

What is a googolplex?

A googolplex is an even larger number than a googol. It is defined as 10 to the power of a googol, or 1 followed by a googol zeros.
