A world written in mathematics

The path a planet takes and the line a thrown stone draws are described by the same family of curves. Neptune was found by calculation before any telescope reached it. Mathematics done purely for its own sake turns up working inside machines a century later, and why it fits so well has still not been explained.

첫째 단서 — 구조Shapes that recur in nature settle into a handful of equations. The path a planet takes and the line a thrown stone draws are described by the same family of curves. Things that looked unrelated tie into one line.
둘째 단서 — 목적Equations were made to explain, and they do more than explain. They predict. They find on paper what no one has seen yet. Neptune was found by calculation before any telescope reached it.
셋째 단서 — 질서Pure mathematics done for its own sake turns up working inside a machine a century later. Why mathematics fits this world so well has still not been explained.

An equation on paper works a century later in your pocket. No one has yet explained why it fits.
