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: In May 2013, the club launched a new crest to improve the reproducibility of the design in print and broadcast media, particularly on a small scale. Critics[who?] suggested that it was external pressure from sports manufacturers Nike, Inc. that evoked the redesign as the number of colours has been reduced and the radial effect have been removed, making the kit more cost efficient to reproduce.[citation needed] The redesign was poorly received by supporters, with a poll on an Everton fan site registering a 91% negative response to the crest. A protest petition reached over 22,000 signatures before the club offered an apology and announced a new crest would be created for the 2014–15 season with an emphasis on fan consultation. Shortly afterwards, the Head of Marketing left the club.

What was the approval rating of the original Everton crest?

QUES: Orthodox Judaism collectively considers itself the only true heir to the Jewish tradition. The Orthodox Jewish movements consider all non-Orthodox Jewish movements to be unacceptable deviations from authentic Judaism; both because of other denominations' doubt concerning the verbal revelation of Written and Oral Torah, and because of their rejection of Halakhic precedent as binding. As such, Orthodox Jewish groups characterize non-Orthodox forms of Judaism as heretical; see the article on Relationships between Jewish religious movements.

Orthodox Jewish groups reject what precedent?
