QUES: The hourglass uses the flow of sand to measure the flow of time. They were used in navigation. Ferdinand Magellan used 18 glasses on each ship for his circumnavigation of the globe (1522). Incense sticks and candles were, and are, commonly used to measure time in temples and churches across the globe. Waterclocks, and later, mechanical clocks, were used to mark the events of the abbeys and monasteries of the Middle Ages. Richard of Wallingford (1292–1336), abbot of St. Alban's abbey, famously built a mechanical clock as an astronomical orrery about 1330. Great advances in accurate time-keeping were made by Galileo Galilei and especially Christiaan Huygens with the invention of pendulum driven clocks along with the invention of the minute hand by Jost Burgi.

QUES: The revived Georgian style that emerged in Britain at the beginning of the 20th century is usually referred to as Neo-Georgian; the work of Edwin Lutyens includes many examples. Versions of the Neo-Georgian style were commonly used in Britain for certain types of urban architecture until the late 1950s, Bradshaw Gass & Hope's Police Headquarters in Salford of 1958 being a good example. In both the United States and Britain, the Georgian style is still employed by architects like Quinlan Terry Julian Bicknell and Fairfax and Sammons for private residences.

At the start of rescue operations on May 12, 20 helicopters were deployed for the delivery of food, water, and emergency aid, and also the evacuation of the injured and reconnaissance of quake-stricken areas. By 17:37 CST on May 13, a total of over 15,600 troops and militia reservists from the Chengdu Military Region had joined the rescue force in the heavily affected areas. A commander reported from Yingxiu Town, Wenchuan, that around 3,000 survivors were found, while the status of the other inhabitants (around 9,000) remained unclear. The 1,300 rescuers reached the epicenter, and 300 pioneer troops reached the seat of Wenchuan at about 23:30 CST. By 12:17 CST, May 14, 2008, communication in the seat of Wenchuan was partly revived.
