Guiding Stars: To find our way around these days we rely on smartphones and a network of global positioning satellites in orbit around the Earth. But if you wanted to navigate your way around in the good old days you had to rely on the stars to help find your way.
A really simple way this can be done is to find Polaris, the "North Pole star." From anywhere in the Northern Hemisphere this star is visible (albeit on the horizon if you are very close to the equator) and can be found by following the two pointer stars in the front of the bowl of the Big Dipper, part of the constellation Ursa Major. Find Polaris and you have found north, from there, the rest is easy.
