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.
We have all heard stories of the Smiths and where they came from, what they did, how many there are, and so on. Well take if from me-a researcher of the Smith name, as well as having the privilege of being one myself-many stories are correct. Our last namesâ¦ are a story handed down for hundreds of years and yet many people donât know what the story means, nor do some care.
