There are infinitely many deltahedra, but only eight that are convex.

He always used to dine at my father's house of a Sunday.

The stunned and broken-handed killer struggled to turn, but the big American grabbed the mangled paw and twisted hard.

Conventional statistical analyses presuppose that intrinsic variability is white noise. White noise yields a jagged and irregular line with a fractal dimension of 1.5, because successive observations are statistically independent of each other. Its fractal dimension indicates the extent to which white noise occupies 2-D space. White noise is uncorrelated noise. By contrast, the successive observations of pink noise tend to be positively correlated. This results in a less jagged trial series, and lower fractal dimensions that fall in the interval between 1 and 1.5.
