Differing logic

Was sent this in an email which probably means that you've already seen it .....

An astronomer, biologist, an engineer and a mathematician were crossing the border into Scotland from England on a train when they saw a field with a black sheep in it.

The astronomer said, "Look--all sheep on Earth are black."

The biologist said, "Look, in Scotland the sheep are black."

The engineer replied, "No, in Scotland some of the sheep are black."

The mathematician rolled his eyes to heaven and said, very patiently, "In Scotland, there exists at least one field, in which there is at least one sheep which is black on at least one side."
