Rae–Richardson Arctic Expedition
The Rae–Richardson Polar Expedition of 1848 was an early British effort to determine the fate of the lost Franklin Polar Expedition. Led overland by Sir John Richardson and John Rae, the team explored the accessible areas along Franklin's proposed route near the Mackenzie and Coppermine rivers. Although no direct contact with Franklin's forces was achieved, Rae later interviewed the Inuit of the region and obtained credible accounts that the desperate remnants of Franklin's team had resorted to cannibalism. This revelation was so unpopular that Rae was effectively shunned by the British Admiralty and popular opinion, and the search for Franklin continued for several years.

Rada (Fiqh)
Raḍāʿ or riḍāʿa (Arabic: رضاع, رضاعة  pronounced [rɪˈdˤɑːʕ(æ)], "breastfeeding") is a technical term in Sunni Islamic jurisprudence (fiqh) meaning "the suckling which produces the legal impediment to marriage of foster-kinship", and refers to the fact that under Sunni jurispurdence, a wet nurse is considered related to the infant she nurses. The term derives from the infinitive noun of the Arabic word radiʿa or radaʿa ("he sucked the breast of his mother"). Often it is translated as "fosterage" or "milk kinship". The concept of radāʿ derives from Islamic and pre-Islamic notions concerning the state of blood relations whereby a wet nurse (and her close relations) and the baby she is nursing (and his or her close family) are deemed related to one another (a status known as mahram) through the act of breastfeeding. One important consequence is that the wet nurse and her family are forbidden to marry the baby and members of the baby's family (e.g. the nursling's biological brother with the milk-mother's biological daughter). Conversely, the milk-relationship allows usually forbidden familiarities between the two groups, (e.g. if the nursling is male, when he becomes an adult he may view the milk-mother and her close female relatives unveiled or in private, exactly as if he were a relation). Thus, according to some Sahih hadith, nursing an adult male could be used as a workaround to Islamic gender segregation, so that a male may be allowed in proximity to the nursing woman, her sisters and her daughters.

Quran Code
The term Quran code (also known as Code 19) refers to the claim that the Quranic text contains a hidden mathematically complex code. Advocates think that the code represents a mathematical proof of the divine authorship of the Quran and they also think that it can be used to identify orthographic errors within the Quranic text. Proponents of the Quran code claim that the Quran code is based on statistical procedures compared to the Bible code, which is ostensibly based on steganography. However, this claim has not been confirmed by any independent mathematical or scientific institute.

Quetzalcoatl
Quetzalcoatl (/ˌkɛtsɑːlkoʊˈɑːtəl/; Spanish: [ket͡salˈkoatʊl] (listen); Template:Lang-nci-IPA, in honorific form: Quetzalcohuātzin, modern Nahuatl pronunciation (help·info)) is a deity in Mesoamerican culture and literature whose name comes from the Nahuatl language and means "feathered serpent" or "Quetzal-feathered Serpent". The earliest known documentation of the worship of a Feathered Serpent occurs in Teotihuacan in the first century BC or first century AD. That period lies within the Late Preclassic to Early Classic period (400 BC – 600 AD) of Mesoamerican chronology; veneration of the figure appears to have spread throughout Mesoamerica by the Late Classic period (600–900 AD). In the Postclassic period (900–1519 AD), the worship of the feathered-serpent deity centred in the primary Mexican religious center of Cholula. In this period the deity is known to have been named "Quetzalcoatl" by his Nahua followers. In the Maya area he was approximately equivalent to Kukulkan and Gukumatz, names that also roughly translate as "feathered serpent" in different Mayan languages. Quetzalcoatl, the Aztec god of wind, air, and learning, wears around his neck the "wind breastplate" ehecailacocozcatl, "the spirally voluted wind jewel" made of a conch shell. This talisman was a conch shell cut at the cross-section and was likely worn as a necklace by religious rulers, as such objects have been discovered in burials in archaeological sites throughout Mesoamerica, and potentially symbolized patterns witnessed in hurricanes, dust devils, seashells, and whirlpools, which were elemental forces that had significance in Aztec mythology. Codex drawings pictured both Quetzalcoatl and Xolotl wearing an ehecailacocozcatl around the neck. Additionally, at least one major cache of offerings includes knives and idols adorned with the symbols of more than one god, some of which were adorned with wind jewels. In the era following the 16th-century Spanish conquest of the Aztec Empire, a number of records conflated Quetzalcoatl with Ce Acatl Topiltzin, a ruler of the mythico-historic city of Tollan. Historians debate to what degree, or whether at all, these narratives about this legendary Toltec ruler describe historical events. Furthermore, early Spanish sources written by clerics tend to identify the god-ruler Quetzalcoatl of these narratives with either Hernán Cortés or Thomas the Apostle— identifications which have also become sources of a diversity of opinions about the nature of Quetzalcoatl. Among the Aztecs, whose beliefs are the best-documented in the historical sources, Quetzalcoatl was related to gods of the wind, of the planet Venus, of the dawn, of merchants and of arts, crafts and knowledge. He was also the patron god of the Aztec priesthood, of learning and knowledge. Quetzalcoatl was one of several important gods in the Aztec pantheon, along with the gods Tlaloc, Tezcatlipoca and Huitzilopochtli. Two other gods represented by the planet Venus are Quetzalcoatl's ally Tlaloc (the god of rain), and Quetzalcoatl's twin and psychopomp, Xolotl. Animals thought to represent Quetzalcoatl include resplendent quetzals, rattlesnakes (coatl meaning "serpent" in Nahuatl), crows, and macaws. In his form as Ehecatl he is the wind, and is represented by spider monkeys, ducks, and the wind itself. In his form as the morning star, Venus, he is also depicted as a harpy eagle. In Mazatec legends the astrologer deity Tlahuizcalpantecuhtli, who is also represented by Venus, bears a close relationship with Quetzalcoatl.

Qingdao Exchange Building
The Qingdao Exchange Building, built in the 1920s, is the largest products and stock exchange building in modern Shandong. In addition to being a historical witness to the economic development of Qingdao over the last 100 years, it has also been a historical scene of cultural exchanges between China and the West after the opening up of China in the early 20th century. After several changes in the building’s property rights, the building was out of use for a long period of time, with a large number of materials and structures being damaged.
