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.
The official language of Greece is Greek. This breaks up into many dialects of Greek with subtle changes in pronunciation and so a Macedonian Greek, a Greek from Athens or Epâ¦irus and a Greek from the island of Crete will all understand each other very easily.
