Q.E.D.

Q.E.D. is an initialism of the Latin phrase quod erat demonstrandum, meaning "which is what had to be proven". The phrase is traditionally placed in its abbreviated form at the end of a mathematical proof or philosophical argument when what was specified in the enunciation—and in the setting-out—has been exactly restated as the conclusion of the demonstration. The abbreviation thus signals the completion of the proof.

Etymology and early use

The phrase quod erat demonstrandum is a translation into Latin from the Greek ὅπερ ἔδει δεῖξαι (hoper edei deixai; abbreviated as ΟΕΔ). Translating from the Latin into English yields, "what was to be demonstrated"; however, translating the Greek phrase ὅπερ ἔδει δεῖξαι produces a slightly different meaning. Since the verb "δείκνυμι" also means to show or to prove, a better translation from the Greek would read, "The very thing it was required to have shown." The phrase was used by many early Greek mathematicians, including Euclid and Archimedes.

Development

The manga was first serialised in Magazine GREAT in 1997, and continued as a Magazine E-no segment in 2009 after Magazine GREAT's cessation. Currently, Q.E.D. is serialized in Magazine Plus, and, as of October 2014, 49 volumes of tankōbon have been released.

Q.E.D. (U.S. TV series)

Q.E.D. is a 1982 adventure television series set in Edwardian England, starring Sam Waterston as Professor Quentin Everett Deverill. The Professor was a scientific detective in the mold of Sherlock Holmes, and the series had a smattering of what would later be called steampunk. In the show, the lead character was known primarily by his initials, Q.E.D; the reference here is that Q.E.D. usually stands for quod erat demonstrandum, a statement signalling the end of a proof.

The first game of the Halo franchise, it was released on November 15, 2001, as a launch title for the Xbox gaming system, and is considered the platform's "killer app". More than five million copies were sold worldwide by November 2005. Microsoft released versions of the game for Microsoft Windows and Mac OS X in 2003, and the surrounding storyline was adapted and elaborated into a series of novels, comic books, and live-action web series.

Players battle various aliens as they attempt to uncover the secrets of the eponymous Halo, a ring-shaped artificial world. The game has been commended for elements such as its story, the variety of strategies players can employ, and its multiplayer mode; however, the repetitive nature of its level design was criticized by some reviewers.
