It's fairly easy to use 32 dominoes, each two squares in
size, to cover a regular 8x8 chess board.
 What if you remove one of the corners from the board.
 Can it still be covered?
 How many dominoes will it take?
 What if you remove two adjacent corners.
 Can the board be covered now?
 How many dominoes will it take?
 What about removing opposite corners?

Starting with these questions the talk goes on to explore pattern,
possibility and proof, looking at necessary versus sufficient, and
how we can be sure that something really is impossible.

with the wellknown popular maths question
about covering a chess board with dominoes,
and move on from there.
