Problem: Hardy Rodenstock (born December 7, 1941 in Marienwerder (Kwidzyn), legal name Meinhard Gorke ) is a former publisher and manager of pop and Schlager music in Germany and is a prominent wine collector, connoisseur, and trader, with a special interest in old and rare wines. He became famous for his allegedly uncanny ability to track down old and very rare wines, and for arranging extravagant wine tastings featuring these wines. It has been alleged that Rodenstock is the perpetrator of an elaborate wine fraud. In 1992, a German court found that Rodenstock had "knowingly offered adulterated wine" for sale.

In May 2008, a book about the controversy was published under the title The Billionaire's Vinegar, written by Benjamin Wallace. In the book a tritium test and two carbon-14 tests date the wine circa 1962. Later, a cesium-137 test gave similar results. Rodenstock was not available for comments on the publication of the book. Auctioneer Michael Broadbent, on the other hand, was unhappy with how his relationship to Rodenstock was portrayed in the book. In July 2009 it was announced that Michael Broadbent would sue Random House, the publishers of The Billionaire's Vinegar, for libel and defamation of character, on claims that the book made allegations that suggested that Broadbent had behaved in an unprofessional manner in the way in which he had auctioned some of these bottles and that his relationship and dealings with Hardy Rodenstock was suspected of being improper. The suit was filed in the United Kingdom, whose libel laws are favorable to the plaintiff. Unlike U.S. law, in English defamation law even true allegations can be defamatory. Random House initially stated it did not believe it had defamed Broadbent and would defend the lawsuit. In October 2009, Random House, avoiding trial, entered into a settlement agreement with Broadbent. In a statement read out in open court, Random House apologised unreservedly for making the allegations, and accepted that they were untrue. It gave an undertaking not to repeat the allegations and paid Broadbent undisclosed damages. It removed the book from sale in the United Kingdom. It also was reported that Wallace was not a party to the lawsuit or settlement, that Random House would be making no changes to the book, and that it would continue to publish the book in all territories except the UK. The film rights to The Billionaire's Vinegar have been purchased by a Hollywood consortium, while HBO simultaneously had bought the film rights to the corresponding The New Yorker article.

Problem: 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.
