**Euler is everywhere!**

There are many useful applications
to Euler circuits and paths. In mathematics, networks can be used to solve
many difficult problems, like the Konigsberg Bridge
problem. They can also be used to by mail carriers who want to have
a route where they don't retrace any of their previous steps. Euler circuits
and paths are also useful to painters, garbage collectors, airplane pilots
and all world navigators, like you!
To get a better sense of how
Euler circuits and paths are useful in the real world,

check out any (or all) of
the following examples.

1. Take a trip through the
Boston Science Museum.

2. Fly the friendly skies and
pretend **you** are the pilot.

3. Navigate a trip to see all
different regions of the world.
