teeny and HUGE Numbers

In Diploma Mathematical Studies we are starting the course looking at the story of Number and how we communicate all sorts of things with different types of Numbers.

You are all probably familiar with Natural Numbers and Integers but there are also Rational, Real and Imaginary numbers. When society needs more from mathematics to push through and develop in some way we develop new systems to make that possible.

Number types tell the story of society and its complexity.

FSU (where my dad did his doctorate) and their famous Powers of ten

We have had these types of numbers in this blog before. Please visit or revisit for your mathematical enjoyment about the scale of the universe(s).
