Sumi is the Japanese word for a form of activated charcoal that is used domestically in a wide range of applications. It is produced by firing certain species of oak or bamboo in clay kilns at temperatures of up to 1000 degrees celsius for as long as ten days. Unlike the ordinary charcoal used at a barbecue, sumi retains the natural shape of the raw wood while becoming harder and denser. After being removed from the kiln, washed and properly prepared, Sumi has the appearance and feel of polished stone.
Sumi also refers to the ink used for writing with a writing brush, particularly in calligraphy, a style called sumi-e in Japan.
The Philosophy of Sumi-e is contrast and harmony, expressing simple beauty and elegance. The Tai Chi diagram demonstrates the perfectly balanced interchange of the two dynamically opposed forces of the Universe, the dot represents integration. Sumi-e employs these principles of nature's vitality in its design and execution. The balance and integration of these forces and the eternal interaction of Yin Yang are the ultimate goal of Sumi-e. The art of brush painting, aims to depict the spirit, rather than the semblance of the object. In creating a picture the artist must grasp the spirit of the subject. Sumi-e attempts to capture the Chi or "life spirit" of the subject, painting in the language of the spirit. Patience is essential in brush painting. Balance, rhythm and harmony are the qualities the artist strives for by developing patience, self-discipline and concentration. The goal of the brush painter is to use the brush with both vitality and restraint. Constantly striving to be a better person because his character and personality come through in his work.
Sumi also means Software Usability Measurement Inventory which is a commercial questionnaire and analysing solution for determining the usability of software. more information on [1].
