Size zero Size zero Size zero or size 0 is a women's clothing size in the US catalog sizes system. Size 0 and 00 were invented due to the changing of clothing sizes over time (referred to as vanity sizing or size inflation), which has caused the adoption of lower numbers. For example, a 2011 size 0 is equivalent to a 2001 size 2, and is larger than a 1970 size 6 or 1958 size 8. Modern size 0 clothing, depending on brand and style, fits measurements of chest-stomach-hips from 30-22-32 inches (76-56-81 cm) to 36-28-36 inches (90-71½-90 cm). Size 00 can
Brain size to body size. The relationship is not proportional, however; the brain-to-body mass ratio varies. The largest ratio found is in the shrew. Averaging brain weight across all orders of mammals, it follows a power law, with an exponent of about 0.75. This power law formula applies to the "average" brain of mammals taken as a whole, but each family (cats, rodents, primates, etc.) departs from it to some degree, in a way that generally reflects the overall "sophistication" of behavior. Primates, for a given body size, have brains 5 to 10 times as large as the formula predicts. Predators tend
