The harmonic mean is the special case of the power mean and is one of the Pythagorean means. In older literature, it is sometimes called the subcontrary mean. The volume-to-surface area ratio for a cylindrical container with height and radius and the mean curvature of a general surface are related to the harmonic mean.
The name SMITH is probably the most common of all surnames. The only names that give it any competition for this title would be Jones and Johnson. The most widely accepted derivation of the name is from the Anglo-Saxon SMITAN and the Germanic verb âSmioanâ meaning to smite or strike.
In the 1990 and 2000 Census results, Smith was the most popular last name in the United States. Maybe your last name is Smith, or Garcia or Miller: do you know the meaning and the history of this part of you that you write and say daily? One reason that the name is so common is because blacksmithing was a specialized craft practiced in many places.
