Question:
Jane Jacobs (born Jane Butzner; May 4, 1916 - April 25, 2006) was an American-Canadian journalist, author, and activist who influenced urban studies, sociology, and economics. Her book The Death and Life of Great American Cities (1961) argued that urban renewal did not respect the needs of city-dwellers. It also introduced the sociological concepts "eyes on the street" and "social capital". Jacobs organized grassroots efforts to protect neighborhoods from "slum clearance", in particular Robert Moses' plans to overhaul her own Greenwich Village neighborhood.
In 1935, during the Great Depression, she moved to New York City with her sister Betty. Jane Butzner took an immediate liking to Manhattan's Greenwich Village, which did not conform to the city's grid structure. The sisters soon moved there from Brooklyn. During her early years in the city, Jacobs held a variety of jobs working as a stenographer and freelance writer, writing about working districts in the city. These experiences, she later said, "... gave me more of a notion of what was going on in the city and what business was like, what work was like." Her first job was for a trade magazine as a secretary, then an editor. She sold articles to the Sunday Herald Tribune, Cue magazine, and Vogue. She studied at Columbia University's School of General Studies for two years, taking courses in geology, zoology, law, political science, and economics. About the freedom to pursue study across her wide-ranging interests, she said: For the first time I liked school and for the first time I made good marks. This was almost my undoing because after I had garnered, statistically, a certain number of credits I became the property of Barnard College at Columbia, and once I was the property of Barnard I had to take, it seemed, what Barnard wanted me to take, not what I wanted to learn. Fortunately my high-school marks had been so bad that Barnard decided I could not belong to it and I was therefore allowed to continue getting an education.

Question:
Hunter was born in New York City, the son of Gertrude (nee Gelien) and Charles Kelm. His mother, from Hamburg, was a German Roman Catholic immigrant, and his father was Jewish. Hunter's father was reportedly abusive, and within a few years of his birth, his parents divorced. Tab grew up in California with his mother, older brother Walter, and maternal grandparents, John Henry and Ida (nee Sonnenfleth)
One of Hunter's first films for Warners was The Sea Chase (1955), supporting John Wayne and Lana Turner. It was a big hit, but Hunter's part was relatively small. Rushes were seen by William Wellman, who cast Hunter to play the younger brother of Robert Mitchum in Track of the Cat (1955). It was a solid hit and Hunter began to get more notice. His breakthrough role came when he was cast as the young Marine Danny in 1955's World War II drama Battle Cry. His character has an affair with an older woman, but ends up marrying the girl next door. It was based on a bestseller by Leon Uris and became Warner Bros largest grossing film of that year, cementing Hunter's position as one of Hollywood's top young romantic leads. In September 1955 the tabloid magazine Confidential reported Hunter's 1950 arrest for disorderly conduct. The innuendo-laced article, and a second one focusing on Rory Calhoun's prison record, were the result of a deal Henry Willson had brokered with the scandal rag in exchange for not revealing his more prominent client Rock Hudson's sexual orientation to the public. Not only did this have no negative effect on Hunter's career, a few months later he was named Most Promising New Personality in a nationwide poll sponsored by the Council of Motion Picture Organizations. In 1956, he received 62,000 Valentines. Hunter, James Dean and Natalie Wood were the last of the actors placed under exclusive studio contract to Warner Bros. Warners decided to promote him to star status, teaming him with Natalie Wood in two back-to-back films, a Western, The Burning Hills (1956), directed by Heisler, and The Girl He Left Behind (1956), a service comedy. These films also proved to be hits with audiences and Warners planned a third teaming of Hunter and Wood. Hunter rejected the third picture, thus ending Warner's attempt to make Tab and Natalie the William Powell and Myrna Loy of the 1950s. Hunter was Warner Bros.' most popular male star from 1955-1959.

Question:
Shen Kuo (Chinese: Chen Gua ; 1031-1095), courtesy name Cunzhong (Cun Zhong ) and pseudonym Mengqi (now usually given as Mengxi) Weng (Meng Xi Weng ), was a Han Chinese polymathic scientist and statesman of the Song dynasty (960-1279). Excelling in many fields of study and statecraft, he was a mathematician, astronomer, meteorologist, geologist, zoologist, botanist, pharmacologist, agronomist, archaeologist, ethnographer, cartographer, encyclopedist, general, diplomat, hydraulic engineer, inventor, academy chancellor, finance minister, governmental state inspector, poet, and musician.
Since the time of the engineer and inventor Ma Jun (c. 200-265), the Chinese had used the south-pointing chariot, which did not employ magnetism, as a compass. In 1044 the Collection of the Most Important Military Techniques (Wu Jing Zong Yao ; Wujing Zongyao) recorded that fish-shaped objects cut from sheet iron, magnetized by thermoremanence (essentially, heating that produced weak magnetic force), and placed in a water-filled bowl enclosed by a box were used for directional pathfinding alongside the south-pointing chariot. However, it was not until the time of Shen Kuo that the earliest magnetic compasses would be used for navigation. In his written work, Shen Kuo made the first known explicit reference to the magnetic compass-needle and the concept of true north. He wrote that steel needles were magnetized once they were rubbed with lodestone, and that they were put in floating position or in mountings; he described the suspended compass as the best form to be used, and noted that the magnetic needle of compasses pointed either south or north. Shen Kuo asserted that the needle will point south but with a deviation, stating "[the magnetic needles] are always displaced slightly east rather than pointing due south." Shen Kuo wrote that it was preferable to use the twenty-four-point rose instead of the old eight compass cardinal points -- and the former was recorded in use for navigation shortly after Shen's death. The preference of use for the twenty-four-point-rose compass may have arisen from Shen's finding of a more accurate astronomical meridian, determined by his measurement between the pole star and true north; however, it could also have been inspired by geomantic beliefs and practices. The book of the author Zhu Yu, the Pingzhou Table Talks published in 1119 (written from 1111 to 1117), was the first record of use of a compass for seafaring navigation. However, Zhu Yu's book recounts events back to 1086, when Shen Kuo was writing the Dream Pool Essays; this meant that in Shen's time the compass might have already been in navigational use. In any case, Shen Kuo's writing on magnetic compasses has proved invaluable for understanding China's earliest use of the compass for seafaring navigation.
