In physics, intensity is the power transferred per unit area, where the area is an imagined surface that is perpendicular to the direction of propagation of the energy. In the SI system, it has units watts per square metre (W/m 2).
The Ancient Greeks spoke Ancient Greek with three different major dialects: Aeolic, Doric and Ionic. They were the first Europeans to both read and write with an alphabet. This alphabet eventually led to the development of all modern European languages.
Modern Greek is a descendant of Proto-Greek, the ancestor of the ancient Greek dialects that were spoken in different areas of Greece before the 4th century BC and which were gradually replaced by a variety of Greek called Common Greek or Koine (ÎºÎ¿Î¹Î½Î®) based on the Attic dialect spoken around Athens.
