Lead each into a room in which there is a kettle of water on the
floor, a stove, and a table, and ask them to boil the water.
They'll both pick the kettle up off the floor and put it on the
stove.
Now repeat the experiment with the kettle sitting on the table.
The physicist will pick the kettle up from the table and put it
on the stove.
The mathematician, on the other hand, will move the kettle from
the table to the _floor_, and smugly announce that he has now
reduced this to a previously solved problem.
