An engineer, a mathmatician and an arts graduate were given the task of finding the height of a church steeple (the first to get the correct solution wins a $1000).

The engineer tried to remember things about differential pressures, but resorted to climbing the steeple and lowering a string on a plumb bob until it touched the ground and then climbed down and measured the length of the string.

The Mathematician layed out a reference line, measured the angle to the top of the steeple from both ends and worked out the height by trigonometry.

However, the arts graduate won the prize. He bought the vicar a beer in the local pub and he told him how high the church steeple was.
