Area

Area is the quantity that expresses the extent of a two-dimensional figure or shape, or planar lamina, in the plane. Surface area is its analog on the two-dimensional surface of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).

The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m²), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares. In mathematics, the unit square is defined to have area one, and the area of any other shape or surface is a dimensionless real number.

Memoria

Memoria was the term for aspects involving memory in Western classical rhetoric. The word is Latin, and can be translated as "memory."

It was one of five canons in classical rhetoric (the others being inventio, dispositio, elocutio, and pronuntiatio) concerned with the crafting and delivery of speeches and prose.

The art of rhetoric grew out of oratory, which was the central medium for intellectual and political life in ancient Greece. Legal proceedings, political debates, philosophical inquiry were all conducted through spoken discourse. Many of the great texts from that age were not written texts penned by the authors we associate them with, but were instead orations written down by followers and students. In Roman times, while there was a much greater body of written work, oration was still the medium for critical debate. Unlike public speakers of today, who use notes or who read their speeches, good orators were expected to deliver their speeches without such aids.

Memoria was the discipline of recalling the arguments of a discourse. It generally received less attention from writers than other parts of rhetoric, as there is less to be said about the subject. However, the need to memorize speeches did influence the structure of discourse to some extent. For example, as part of dispositio, some attention was paid to creating structures (such as the divisio, an outline of the major arguments of a discourse) that would also aid memory. Some writers also discussed the use of various mnenomic devices to assist speakers.

Demetrio Stratos

Efstratios Dimitriou (Greek: Ευστράτιος Δημητρίου; April 22, 1945 – June 13, 1979), better known as Demetrio Stratos, was a Greek lyricist, multi-instrumentalist, music researcher, and co-founder, frontman and lead singer of the Italian progressive rock band Area – International POPular Group.

Born and raised in Alexandria, Egypt, of Greek parents, he studied piano and accordion at the "National Conservatoire". In 1957 he was sent to Nicosia, Cyprus, and, at the age of 17, moved to Milan, Italy, to attend the Politecnico di Milano University at the Architecture Faculty, where he formed his first musical group. In 1967, Demetrio Stratos joined the Italian beat band I Ribelli, and in 1972, founded Area.

Stratos recorded many records, and toured festivals in Italy, France, Portugal, Switzerland, Netherlands, Cuba, U.S. with Area, as well as a solo artist and in collaboration with other artists. He worked together with musicians, singers, writers, poets, directors, men of learning such as Mogol, Lucio Battisti, Gianni Sassi, Gianni Emilio Simonetti, Juan Hidalgo, Walter Marchetti, John Cage, Tran Quang Hai, Merce Cunningham, Jasper Johns, Andy Warhol, Grete Sultan, Paul Zukofsky, Nanni Balestrini, Claude Royet-Journoud, and Antonio Porta.
