Einstein Relatively Easy

Pin It


In General Relativity, these are the curves that a free particle (that is, a particle upon which no force acts, where ‘force’ in this case excludes gravity, since the effects of gravity are felt entirely through the curvature of space-time) will follow in a curved space-time .

A geodesic could be equivalently defined as:


The Einstein's Derivation of the Geodetic Equation from a variationnal approach (Extract from the Manuscript "The Foundation of the General Relativity of Relativity §9 1916)



[1] Refer to our article Geodesics as proper time maximization to see how this applies also in Special Relativity.

"Five or six weeks elapsed between the conception of the idea for the special theory of relativity and the completion of the relevant publication" Einstein to Carl Seeling on March 11, 1952

"Every boy in the streets of Göttingen understands more about four-dimensional geometry than Einstein. Yet, in spite of that, Einstein did the work and not the mathematicians."
David Hilbert
