Finding your way from A to B while at the same time contemplating the universe:

Most of us can easily identify Polaris in the night sky and know that it accurately represents ‘true’ North, the pole of the Earth’s rotational axis. Stars and constellations other than Polaris are also useful for orientation. But unlike Polaris they are subject to the diurnal and seasonal wheeling of the sky, its apparent motion due to the Earth’s rotation.  What you see on the horizon depends of course additionally on your latitude & longitude. Thanks to  Kepler, Newton and co, everything can be precisely calculated… and rendered on your smartphone!
