Imagine an ant working at the top of a mountain. Next to it, there’s a sluice of melt water running and, at that moment, the ant removes a tiny particle from the rock face. A few hundred molecules of water quickly seize upon the shortcut, and gravity takes care of the rest. The individual rivulets on the mountain’s face eventually run together in a small brook, jostling pebbles and twigs along its bubbly trough. Running ever downwards, doubling in speed and force, the stream now catches up rocks, branches and other streams join the flow. Almost effortlessly, a mighty river is born carving its way through the massive granite over millennia. The imprint upon the surrounding landscape is a culmination of billions of tiny actions – wind, rain fall, freezes and even one tiny ant.
