Urban means "related to cities." It may refer to:
Urban (1076–1134) was the first bishop of South East Wales to call himself 'bishop of Llandaff'. He was of a Welsh clerical family and his baptismal name in the Welsh language is given in charter sources as Gwrgan. He Latinised it to the papal name 'Urban'.
Urban came from one of the dominant Anglo-Welsh clerical dynasties of what was called in the eleventh century the diocese of Glamorgan. Two of his brothers are known: one called Caradoc the priest and the other, Gwrgan of Llancarfan. This would indicate that his family origins derived from the important clerical community of Llancarfan. The petition of the 'clergy and people' of Glamorgan in support of his election as bishop says that he had been consecrated priest in the English diocese of Worcester. This more than hints that Urban, as with several other known clerics from the southern Welsh dioceses, had been sent to England to be educated. He was already a leading cleric under his Anglo-Welsh predecessor, Bishop Herewald (1056–1104), occupying the office of archdeacon of Llandaff. At the time of his election as bishop in 1107 he was said to be thirty-one years of age, which if true would give a date of birth of 1076.

In quantum mechanics, "observation" is synonymous with quantum measurement and "observer" with a measurement apparatus and "observable" with what can be measured. Thus the quantum mechanical observer does not have to necessarily present or solve any problems over and above the (admittedly difficult) issue of measurement in quantum mechanics. The quantum mechanical observer is also intimately tied to the issue of observer effect.
A number of interpretations of quantum mechanics, notably "consciousness causes collapse", give the observer a special role, or place constraints on who or what can be an observer. For instance, Fritjof Capra writes:
"The crucial feature of atomic physics is that the human observer is not only necessary to observe the properties of an object, but is necessary even to define these properties. ... This can be illustrated with the simple case of a subatomic particle. When observing such a particle, one may choose to measure — among other quantities — the particle's position and its momentum"
Observer (also known as Brain Guy) is a fictional character in the Mystery Science Theater 3000 television series. He is played by Bill Corbett, and appears in the eighth through tenth seasons of the series.
Observer is a hyperintelligent, psychic alien from a planet of fellow aliens confusingly sharing the name "Observer" (the other two who appear in the series are played by Michael J. Nelson and Paul Chaplin). Supposedly, the Observers "evolved" beyond bodies into dark-green brains, contained in large Petri dishes (not unlike the Providers in the Star Trek episode "The Gamesters of Triskelion"). They are carried around by humanoid host bodies (controllable over a distance of up to 50 yards), rendering their abandonment of their original bodies rather pointless. (As the robot Gypsy points out, "Wouldn't it be more convenient to just keep your brains in your heads?") Thus Observer is, technically, only the brain which is being carried by the host body, but for all intents and purposes, he is considered a humanoid with brain separated from body. Observer joins the mad scientists ("The Mads") after his planet is inadvertently destroyed by Mike Nelson.
Blizzard Entertainment's bestselling real-time strategy game series StarCraft revolves around interstellar affairs in a distant sector of the galaxy, with three species and multiple factions all vying for supremacy in the sector. The playable species of StarCraft include the Terrans, humans exiled from Earth who excel at adapting to any situation; the Zerg, a race of insectoids obsessed with assimilating other races in pursuit of genetic perfection; and the Protoss, a humanoid species with advanced technology and psionic abilities, attempting to preserve their civilization and strict philosophical way of living from the Zerg. Each of these races has a single campaign in each StarCraft real-time strategy game. In addition to these three, various non-playable races have also been part of the lore of the StarCraft series; the most notable of these is the Xel'Naga, a race which features prominently in the fictional histories of the Protoss and Zerg races.
The original game has sold over 10 million copies internationally, and remains one of the most popular games in the world. One of the main factors responsible for StarCraft's positive reception is the attention paid to the three unique playable races, for each of which Blizzard developed completely different characteristics, graphics, backstories and styles of gameplay, while keeping them balanced in performance against each other. Previous to this, most real-time strategy games consisted of factions and races with the same basic play styles and units with only superficial differences. The use of unique sides in StarCraft has been credited with popularizing the concept within the real-time strategy genre. Contemporary reviews of the game have mostly praised the attention to the gameplay balance between the species, as well as the fictional stories built up around them.
Denkmäler deutscher Tonkunst (literally "Monuments of German musical art") is a historical edition of music from Germany, covering the Baroque and Classical periods.
The edition comprises two series: the first appeared in sixty-five volumes between 1892 and 1931, and the second, which was subtitled Denkmäler der Tonkunst in Bayern (Monuments of musical art in Bavaria), in thirty-six volumes between 1900 and 1931. The first series was issued by a Prussian royal commission of celebrity musicians and musicologists in instalments through the music publishers Breitkopf & Härtel in Leipzig, and the second by the Society for the Publication of Monuments of Musical Art in Bavaria.
A parallel series of volumes on Austrian composers, Denkmäler der Tonkunst in Österreich (Monuments of musical art in Austria), was begun in 1959, and as at 2015-10-25 is in progress at one hundred and fifteen volumes.
