The Einstein and bulldozers puzzle solution.

So what's the link between Einstein and bulldozers? It was quite intriguing for me to find out on Saturday that bulldozers can use GPS systems.

Damian Pope, the usual presenter of the regular Perimeter Institute's Black Hole sessions used this puzzle to give us an unusual example of modern physics use in everyday life. It is well known that the success of GPS systems depends on Einstein's Relativity Theory (check out for example Clifford Will's EinsteinFest presentation starting at minute 62:20, as I documented it in one of my previous posts).
