In last week’s post, we have talked about large numbers and their importance to scientific studies and everyday life. In this post, we talk about one of the most famous large numbers: googol.

A googol is the name of the number which is $10^{100}$ or a $1$ followed by one hundred zeros. If you are wondering how large it is, well it is fairly large since the number of atoms in the observable universe is only $10^{80}$. That means that we need $10^{20}$ universes, the size of the observable universe, to create a universe with googol number of atoms.

Kasner was famous for his book Mathematics and the Imagination where he introduced the term googol. » Read more

## Exploring Computational Thinking

Exploring Computational Thinking is one of Google’s latest endeavors in K-12 curriculum. Computational thinking (CT), according to Google, involves a set of problem-solving skills and techniques that are commonly used by software engineers to write computer programs. Several of this computational techniques are the following: » Read more
