Navigation is the science of finding the way from one place to another. It applies to all forms of traveling, be it on land, sea, air, or even space. Navigation techniques are most useful when traveling over water. Compared to land travel, reaching a destination over water is complicated and dangerous without special skills. There are no roads to follow or landmarks to look for. A simple mistake could have deadly results.
