Zaza is a 1923 American silent romantic drama film directed and produced by Allan Dwan, and starring Gloria Swanson. This film is based on the 1899 French play of the same name produced on Broadway by David Belasco and starring Mrs. Leslie Carter. A print of the film is housed at the George Eastman House and the Library of Congress.
A previous film version was released by Paramount in 1915 starring Pauline Frederick. A third version, directed by George Cukor and starring Claudette Colbert, was released in 1939.

Zaza is a play, originally written by French playwrights Pierre Berton and Charles Simon, but probably best known in the English-speaking world in the 1898 adaptation by David Belasco. The title character is a prostitute who becomes a music hall entertainer and the mistress of a married man. According to the IMDb, it was produced on stage and in film six times between 1913 and 1956. The IMDB's best-documented instance is the 1939 production starring Claudette Colbert as Zaza, Herbert Marshall as the man whose mistress she becomes, and Bert Lahr as her music-hall partner.

A chord of a circle is a straight line segment whose endpoints both lie on the circle. A secant line, or just secant, is the infinite line extension of a chord. More generally, a chord is a line segment joining two points on any curve, for instance an ellipse. A chord that passes through a circle's center point is the circle's diameter.
Chords of a circle
Among properties of chords of a circle are the following:
The area that a circular chord "cuts off" is called a circular segment.
Chord is from the Latin chorda meaning bowstring.
Chords of an ellipse
The midpoints of a set of parallel chords of an ellipse are collinear.
Chords in trigonometry
Chords were used extensively in the early development of trigonometry. The first known trigonometric table, compiled by Hipparchus, tabulated the value of the chord function for every 7.5 degrees. In the second century AD, Ptolemy of Alexandria compiled a more extensive table of chords in his book on astronomy, giving the value of the chord for angles ranging from 1/2 degree to 180 degrees by increments of half a degree. The circle was of diameter 120, and the chord lengths are accurate to two base-60 digits after the integer part.
In the field of astronomy the term chord typically refers to a line crossing an object which is formed during an occultation event. By taking accurate measurements of the start and end times of the event, in conjunction with the known location of the observer and the object's orbit, the length of the chord can be determined giving an indication of the size of the occulting object. By combining observations made from several different locations, multiple chords crossing the occulting object can be determined giving a more accurate shape and size model. This technique of using multiple observers during the same event has been used to derive more sophisticated shape models for asteroids, whose shape can be highly irregular. A notable example of this occurred in 2002 when the asteroid 345 Tercidina underwent a stellar occultation of a very bright star as seen from Europe. During this event a team of at least 105 observers recorded 75 chords across the asteroid's surface allowing for a very accurate size and shape determination.
Andrew Chord is a fictional character appearing in American comic books published by Marvel Comics. He is African American. His first appearance was in Thor #411. Chord was the mentor of Night Thrasher and the New Warriors. He is also the father of Silhouette and Midnight's Fire and the son-in-law of Warriors villain Tai.
Fictional character biography
Andrew Chord was an American soldier, an army sergeant during the Vietnam war. His unit (calling themselves the "Half Fulls") was in the plateau dus bolovens north of the Se Kong river in Cambodia where they were looking to scout locations for a possible landing base for American aircraft. His unit of six soldiers (including Night Thrasher's father Daryl Taylor, Diego Cassaes a.k.a. the Left Hand and the fathers of the members of the Folding Circle) encountered a mysterious building known as the Temple of the Dragon's Breadth. They soon encountered a seemingly English speaking Cambodian geriatric named Tai who restrained them via magic. Tai explained to the soldiers the history of her people and the need for the soldiers to mate with six young women from her cult. The soldiers were led to believe that through these matings their children would one day rule the world. Five of the soldiers agreed to this pact. Daryl Taylor refused his bride because he was already married to his wife Melody.
