"Happiest thought of my life"
A freely falling frame is an inertial frame!
Principle of Equivalence Einstein's 'thought experiments'

March 1912
ALL acceleration derived from gravitational and inertial forces are 'metrical in origin'
Let us break up Newton's law into two parts:
Einstein's basic premise
1912: Einstein returns to Zurich
Einstein - Grossman collaboration
Einstein's basic premise: 1912
Einstein-Grossmann paper - 1913

Newtonian Gravity
In regions where no matter is present
In regions where matter is present
Conservation Laws
Einstein's field equations
Newtonian limit
Einstein-Hilbert field equations
The Schwarzschild Solution
On the Hypotheses which lie at the Bases of Geometry. Bernhard Riemann
Nature and Nature's laws lay hid at night: God said, Let Newton be! and all was light.
