How Does a Compass Find North?

Hold a compass and the needle settles on north — pulled by an ocean of molten iron 2,900 km beneath your feet. Tonight: the shepherd whose sandals stuck to a magnetic mountain, China's south-pointing spoon, the monk who watched sailors spin a needle in the dark — and the birds that see the field with their eyes. Just long enough to fall asleep to. 🌙
