Title: What are amenable groups and why are groups non-amenable

Abstract: I will give an introduction to amenable

groups and explain the result of Kevin Whyte that a

countable non-amenable group admits a

"translation-like" action by a non-abelian free group.

I will also discuss (without proof) a measure theoretic

analogue of this result due to D. Gaboriau and R. Lyons.
