Problem: Background: Kobe Bean Bryant (born August 23, 1978) is an American former professional basketball player. He played his entire 20-year career with the Los Angeles Lakers of the National Basketball Association (NBA). He entered the NBA directly from high school and won five NBA championships with the Lakers. Bryant is an 18-time All-Star, 15-time member of the All-NBA Team, and 12-time member of the All-Defensive team.
Context: Standing at 6 feet 6 inches tall (1.98 m) and weighing 205 pounds (93 kg), Bryant played primarily as a shooting guard. He was often cited as one of the most dangerous scorers in the NBA. Bryant has drawn frequent comparisons to Jordan, after whom he modeled his playing style. Like Jordan, he became most known for shooting a fall-away jump shot. Chris Ballard of Sports Illustrated described another of Bryant's most famous moves as the "jab step-and-pause": Bryant jabbed his non-pivot foot forward to let the defender relax, but instead of bringing the jab foot back, he pushed off of it and drove around his opponent to get to the basket.  Bryant established a reputation for taking shots in the closing moments of tight games, even when he was double or triple-teamed, and was noted as one of the premier closers in the NBA. In a 2012 annual survey of NBA general managers, Bryant was selected for the 10th consecutive season as the player general managers would want to take a clutch shot with a game on the line. Bryant enjoyed being the villain, and reveled in being booed and then silencing the crowd with his play. His ability to make difficult shots has also drawn criticism of his shot selection. Throughout his career, Bryant was disparaged for being a selfish, high-volume shooter; he missed more field goal attempts in his career than any other player in NBA history. Phil Jackson, who coached Bryant for many years, stated that Bryant "tends to force the action, especially when the game isn't going his way. When his shot is off, Kobe will pound away relentlessly until his luck turns." According to Bryant, "I would go 0 for 30 before I would go 0 for 9; 0 for 9 means you beat yourself, you psyched yourself out of the game."  In addition to his abilities on offense, Bryant also established himself as a standout defensive player. Bryant rarely drew charges when he played defense, which he believed spared his body and contributed to his longevity. Some critics have suggested that Bryant's defensive accolades in his later years were based more on his reputation than his actual play.  Bryant was also lauded for his work ethic. Throughout his first 16 seasons, his body was resilient, and he exhibited a high pain threshold while often playing through injuries. A fierce competitor, Bryant made opponents and teammates alike the objects of his scorn. Many players have considered him difficult to play with because of his high level of commitment and performance. According to sportswriter Mark Heisler of Forbes, "circa 2004-2007, Kobe was the most alienated superstar the NBA had ever seen." He did, however, lead the Lakers to two championships after the departure of Shaquille O'Neal; during this period, he became more of a mentor to his teammates than he had been earlier in his career. Bryant's longtime head coach Phil Jackson noted that the biggest difference between his first and second stints in coaching the Lakers was that during the latter period, "[Bryant] embraced the team and his teammates, calling them up when we were on the road and inviting them out to dinner. It was as if the other players were now his partners, not his personal spear-carriers."
Question: What is notable about his player profile?
Answer: He was often cited as one of the most dangerous scorers in the NBA.

Problem: Background: 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.
Context: 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.
Question: What is the south-point chariot?
Answer:
The south-pointing chariot was another mechanical device credited to Zhang Heng.
