"Geese Migration"
I was traveling in Montana recently with my father, and we saw a flock of migrating geese.
Pointing to it he asked me, "Of course you know that geese fly in a "V" formation to reduce aerodynamic drag. But do you know why one side of the "V" is longer than the other?"
As I was pondering the physics he said...
"Because there are more geese in it."
