Source sentences:
text: The highest curvature occurs where the curve has its highest and lowest points, and indeed in the picture these appear to be the most sharply curved portions of the curve, while the curve is almost a straight line midway between those points.
text: Intuitively, curvature measures the failure of a curve to be a straight line, while torsion measures the failure of a curve to be planar.
text: If the curvature is always zero then the curve will be a straight line.
