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.
Fort Smith's name comes from General Thomas Adams Smith (1781â1844), who commanded the United States Army Rifle Regiment in 1817, headquartered near St. Louis. General Smith had ordered Army topographical engineer Stephen H. Long (1784â1864) to find a suitable site on the Arkansas River for a fort.
