# Friday math movie - Powers of 10

By Murray Bourne, 29 Feb 2008

Here's a movie that will challenge your view of where you fit in the scheme of things.

Video is a great way to get a sense of scale when talking about powers of 10.

For example, they start with a view that is around 1 m wide, then zoom out to view a 10 m (= 10^{1}) wide square, then 100 m (= 10^{2}) and so on, ending up with a view of the universe.

They then go in the other direction, going smaller and smaller: 1/10 m (= 10^{−1}), 0.01 m (= 10^{−2}) and so on, passing through cells, viruses, and down to the atomic level.

The video was made by IBM in 1977.
