Single Idea 17008
[filed under theme 26. Natural Theory / D. Laws of Nature / 6. Laws as Numerical
]
Full Idea
You have made the astonishing discovery that Kepler's ellipses result simply from the conception of attraction or gravitation and passage in a planet.
Gist of Idea
You have discovered that elliptical orbits result just from gravitation and planetary movement

report of Isaac Newton (Principia Mathematica [1687]) by Gottfried Leibniz - Letter to Newton 1693.03.07

A Reaction
I quote this to show that Newton made 'an astonishing discovery' of a connection in nature, and did not merely produce an equation which described a pattern of behaviour. The simple equation is the proof of the connection.
