Question: Duke was born in New York City, the only child of tobacco and hydroelectric power tycoon James Buchanan Duke and his second wife, Nanaline Holt Inman, widow of Dr. William Patterson Inman. At his death in 1925, the elder Duke's will bequeathed the majority of his estate to his wife and daughter, along with $17 million in two separate clauses of the will, to The Duke Endowment he had created in 1924. The total value of the estate was not disclosed, but was estimated variously at $60 million to $100 million (equivalent to $837 million to $1.395 billion in 2018), the majority culled from J.B. Duke's holds in Lucky Strike cigarettes. Duke spent her early childhood at Duke Farms, her father's 2,700-acre (11 km2) estate in Hillsborough Township, New Jersey.

Duke married twice, the first time in 1935 to James H. R. Cromwell, the son of Palm Beach society doyenne Eva Stotesbury. Cromwell, a New Deal advocate like his wife, used her fortune to finance his political career. In 1940 he served several months as U.S. Ambassador to Canada and ran unsuccessfully for the U.S. Senate. The couple had a daughter, Arden, who died one day after her birth. They divorced in 1943.  On September 1, 1947, while in Paris, Duke became the third wife of Porfirio Rubirosa, a diplomat from the Dominican Republic. She reportedly paid his second wife, actress Danielle Darrieux, $1 million to agree to an uncontested divorce. Because of her great wealth, Duke's marriage to Rubirosa attracted the attention of the U.S. State Department, which cautioned her against using her money to promote political agenda. Further, there was concern that in the event of her death, a foreign government could gain too much leverage. Therefore, Rubirosa had to sign a pre-nuptial agreement; during the marriage, though, she gave Rubirosa several million dollars in gifts, including a stable of polo ponies, sports cars, a converted B-25 bomber, and, in the divorce settlement, a 17th-century house in Paris. One of Doris Duke's best friends was Brazilian socialite and "jetsetter" Aimee de Heeren.  She reportedly had numerous affairs, with, among others, Duke Kahanamoku, Errol Flynn, Alec Cunningham-Reid, General George S. Patton, Joe Castro, and Louis Bromfield.  Duke posted a bail of $5,000,000 for her friend, former Philippine First Lady Imelda Marcos after the latter was arrested for racketeering.

Question: Zhang Heng (Chinese: Zhang Heng ; AD 78-139), formerly romanized as Chang Heng, was a Han Chinese polymath from Nanyang who lived during the Han dynasty. Educated in the capital cities of Luoyang and Chang'an, he achieved success as an astronomer, mathematician, scientist, engineer, inventor, geographer, cartographer, artist, poet, statesman, and literary scholar. Zhang Heng began his career as a minor civil servant in Nanyang. Eventually, he became Chief Astronomer, Prefect of the Majors for Official Carriages, and then Palace Attendant at the imperial court.

Zhang Heng is often credited with inventing the first odometer, an achievement also attributed to Archimedes (c. 287-212 BC) and Heron of Alexandria (fl. AD 10-70). Similar devices were used by the Roman and Han-Chinese empires at about the same period. By the 3rd century, the Chinese had termed the device the ji li gu che, or "li-recording drum carriage" (the modern measurement of li = 500 m/1640 ft).  Ancient Chinese texts describe the mechanical carriage's functions; after one li was traversed, a mechanically driven wooden figure struck a drum, and after ten li had been covered, another wooden figure struck a gong or a bell with its mechanically operated arm. However, there is evidence to suggest that the invention of the odometer was a gradual process in Han Dynasty China that centered on the "huang men"--court people (i.e. eunuchs, palace officials, attendants and familiars, actors, acrobats, etc.) who followed the musical procession of the royal "drum-chariot". There is speculation that at some time during the 1st century BC the beating of drums and gongs was mechanically driven by the rotation of the road wheels. This might have actually been the design of Luoxia Hong (c. 110 BC), yet by at least 125 the mechanical odometer carriage was already known, as it was depicted in a mural of the Xiao Tang Shan Tomb.  The south-pointing chariot was another mechanical device credited to Zhang Heng. It was a non-magnetic compass vehicle in the form of a two-wheeled chariot. Differential gears driven by the chariot's wheels allowed a wooden figurine (in the shape of a Chinese state minister) to constantly point to the south, hence its name. The Song Shu (c. AD 500 ) records that Zhang Heng re-invented it from a model used in the Zhou Dynasty era, but the violent collapse of the Han Dynasty unfortunately did not allow it to be preserved. Whether Zhang Heng invented it or not, Ma Jun (200-265) succeeded in creating the chariot in the following century.
