Quotations
1729: And all astronomers agree that their periodic orbits are in the sesquiplicate proportion of the semi-diameters of their orbits; and so it manifestly appears from the following table. — Andrew Motte, translating Isaac Newton's Philosophiae Naturalis Principia Mathematica
- Note: "in the sesquiplicate proportion" (ratio) means increasing as the square root of the cube, that is, as x3/2, just as "in the duplicate ratio" would mean increasing as the square.
