Source sentences:
text: The Gaussian curvature for a continuous surface, u, can also be determined from the ratio of the determinants of the second and first fundamental forms, defined as
text: This is relevant because it means that the curvature of such objects can be determined by measuring angles, for example.
text: Gauss's Theorema egregium (Latin: "remarkable theorem") states that Gaussian curvature of a surface can be determined from the measurements of length on the surface itself.
text: Another way of saying this is that if all forms of dark energy are ignored, then the curvature of the universe can be determined by measuring the average density of matter within it, assuming that all matter is evenly distributed (rather than the distortions caused by 'dense' objects such as galaxies).
text: The "curvature" of a way is determined by iterating over every set of three points in the line.
