The thread discusses Hack's Law, which describes the mathematical relationship between the length of a river and its drainage area. It explores the underlying reasons for this pattern in nature, such as gravity and friction, and highlights the consistency of this law across different river systems worldwide.

#science #technology #nature #geology It's not something that we tend to think about- but rivers are mathematical. Hack's Law states that a river, stream or brook has a length that is proportional to its drainage area raised to the power of 0.6 The question is why? It's obvious that there is a link between size and width of river basins, but this theory holds mostly true all over the world. Gravity and friction play a part. But rivers are not random. https://www.quantamagazine.org/why-are-rivers-so-mathematical-20260810/

Why are rivers so mathematical? Natalie Wolchover writes for Quanta about Hack's law — that any stream has a length that’s proportional to its drainage area raised to the power of 0.6 — and the explanations that underly it. https://flip.it/EIqEbO #Rivers #Science #Mathematics
