TED-ED: A clever way to estimate enormous numbers - Michael Mitchell

The video tutorial explains scientific notation as a method to express large and small numbers in a manageable format. It introduces the concept of using powers of 10 for quick estimations, especially in Fermi problems, which involve making rapid order-of-magnitude estimations with limited data. The tutorial highlights Enrico Fermi's contributions and provides a practical example of estimating the number of piano tuners in Chicago using these techniques.

What is the main purpose of using scientific notation?
