What if Newton's Principia had gone differently?

One book puts motion, gravity and the planets under a single set of equations.

If it had gone differently: There is no unified mathematical physics; the study of motion stays a bag of rules of thumb for another century.

1. 1712The practical steam engine, Power stays tied to water, wind and muscle; factories cluster on rivers and stay small.
2. 1720The Enlightenment, Absolutism keeps its intellectual cover; 'rights of man' never enters common speech.
3. 1780The Industrial Revolution, Growth stays flat and Malthusian; most people alive in 1900 live about as their great-grandparents did.
4. 1905Einstein's relativity, Physics keeps Newton's absolute space and time; the road to nuclear energy, GPS and modern cosmology is blocked.
