Riemann: manifolds, measurement and curvature

What changed

Developed a way to discuss spaces of arbitrary dimension, local measurement and curvature, separating geometrical hypotheses from the question of which geometry describes physical space.

Scientific scope

The 1854 lecture's account of manifolds, metric measurement and curvature.
