Island hopping
THE picture above shows the River Pregel as it
flowed through the town of Konigsberg in the 18th
century. As you cas see, there was an island in the
middle and seven bridges crossing the river. The
citizens of Konigsberg used to enjoy strolling across
the river via one of its many bridges and one of
themposed this puzzle to the great mathematician,
Leonard Euler: "Is it possible to start from a point
of your own choice, and cross each of the bridges
without going over any bridge twice?"What do you
think Euler's answer was?
