on the welfare of the galaxy". Theoretical physicist Thomas Fink defines beauty in The Man's Book both in terms of ships launched and in terms of the number of women, on average, than whom one woman will be more beautiful. He defines one helen (H) as the quantity of beauty to be more beautiful than 50 million women, the number of women estimated to have been alive in the 12th century BCE. Fink also defines a related, but smaller unit called a “helena” (Ha), based on a logarithmic scale, like the Richter scale, or decibels (dB). Ten helena (Ha) is the beauty sufficient for one oarsman (of which 50 are on a ship) to risk his life, or to be the most beautiful of a thousand women. Since the unit is logarithmic on a base of 2, for beauty to increase by 1 Ha, a woman must be the most beautiful of twice as many women, so one helen is equivalent to 25.6 Ha. The most beautiful woman who ever lived would score 34.2 Ha, the equivalent of 1.34 helen, the pick of a dozen women would be 3.6 Ha, or 0.14 helen.
