input: Hughes met his first wife, Danne Emerson, in London in 1967. Together they became involved in the counterculture of the 1960s, exploring drug use and sexual freedom. They divorced in 1981; she died of a brain tumor in 2003. Their son, Danton, Hughes's only child, was named after the French revolutionary Georges Danton. Danton Hughes, a sculptor, committed suicide in April 2001. He had been in a long term relationship with fashion designer Jenny Kee, who found his body on 15 April. Robert Hughes later wrote: "I miss Danton and always will, although we had been miserably estranged for years and the pain of his loss has been somewhat blunted by the passage of time".  Hughes was married to his second wife, Victoria Whistler, a housewife from California, from 1981 until a divorce in 1996.  In 1999, Hughes was involved in a near-fatal car accident south of Broome, Western Australia. He was returning from a fishing trip and driving on the wrong side of the road when he collided head on with another car carrying three occupants. He was trapped in the car for three hours before being airlifted to Perth in critical condition. Hughes was in a coma for five weeks after the crash. In a 2000 court hearing, Hughes's defence barrister alleged that the occupants of the other car had been transporting illicit drugs at the time of the accident and were at fault. In 2003 Hughes pleaded guilty to dangerous driving causing bodily harm and was fined A$2,500. He also allegedly described the crown prosecutor, Lloyd Rayney, as a "curry muncher", which resulted in a defamation action and out-of-court settlement. Hughes recounts the story of the accident and his recovery in the first chapter of his 2006 memoir Things I Didn't Know.  In 2001, Hughes wed his third wife, the American artist and art director Doris Downes. "Apart from being a talented painter, she saved my life, my emotional stability, such as it is", he said.

input: 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.

input: 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.
