In ancient Greek medicine, each of the four humours became associated with an element. Blood was the humor identified with air, since both were hot and wet. Other things associated with air and blood in ancient and medieval medicine included the season of spring, since it increased the qualities of heat and moisture; the sanguine temperament (of a person dominated by the blood humour ...
QI (Quite Interesting) is a British comedy panel game quiz show for television created and co-produced by John Lloyd. The series currently airs on BBC Two and is presented by Sandi Toksvig. It features permanent panellist Alan Davies and three guest panellists per episode; the panellists are mostly comedians. The series was presented by Stephen ...
Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. A related term is magnetizability, the proportion between magnetic moment and magnetic flux density. [3] A closely related parameter is the permeability, which expresses the total ...
t. e. Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities. In these contexts, the capital letters and the small letters represent distinct and unrelated entities.
Chi, or the earth, symbolizes solid matter. Sui, the water, symbolizes liquids. Ka, the fire, is the symbol of combustion, or the elements in an energy-releasing state. Fu, the wind, symbolizes gases. Ku, the void, is representative of the formless subatomic energy that is the basis for the structure of all things.
The Chi-Rho symbol. The Chi Rho (☧, English pronunciation / ˈkaɪ ˈroʊ /; also known as chrismon[1]) is one of the earliest forms of the Christogram, formed by superimposing the first two (capital) letters— chi and rho (ΧΡ)—of the Greek ΧΡΙΣΤΟΣ (rom: Christos) in such a way that the vertical stroke of the rho intersects the ...
Permittivity as a function of frequency can take on real or complex values. In SI units, permittivity is measured in farads per meter (F/m or A 2 ·s 4 ·kg −1 ·m −3). The displacement field D is measured in units of coulombs per square meter (C/m 2), while the electric field E is measured in volts per meter (V/m).
In physics, denotes electric or magnetic susceptibility. In rhetoric, both chiastic structure (a literary device) and the figure of speech Chiasmus derive from their names from the shape of the letter Chi. In mechanical engineering, chi is used as a symbol for the reduction factor of relevant buckling loads in the EN 1993, a European Standard ...
