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.

The term googol was coined in 1938 by Milton Sirrota (he was 9 years old the time he invented the term), nephew of Edward Kasner, an American mathematician. Kasner was famous for his book Mathematics and the Imagination where he introduced the term googol. Continue reading

## How to do Print Screen on iPads

As mathematics teachers, we often need images of things we draw or scribble. Sometimes, we also need to take a picture or a snapshot of our screen. There are many ways to do this on PCs and Macs. In Windows for instance, we press the Print Screen key and on Macs, we press the key combinations Command+Shift+3 (try replacing 3 with 4 or 5 and see what happens). However, with the wide use of tablets nowadays, it is also important to know to perform this function on then such as iPads.

Now, how do we print screen on iPads?

With just a few steps, it is possible to take a snapshot of your iPad screen.
