input: Zhang Heng's mechanical inventions influenced later Chinese inventors such as Yi Xing, Zhang Sixun, Su Song, and Guo Shoujing. Su Song directly named Zhang's water-powered armillary sphere as the inspiration for his 11th-century clock tower. The cosmic model of nine points of Heaven corresponding with nine regions of earth conceived in the work of the scholar-official Chen Hongmou (1696-1771) followed in the tradition of Zhang's book Spiritual Constitution of the Universe. The seismologist John Milne, who created the modern seismograph in 1876 alongside Thomas Gray and James A. Ewing at the Imperial College of Engineering in Tokyo, commented in 1886 on Zhang Heng's contributions to seismology. The historian Joseph Needham emphasized his contributions to pre-modern Chinese technology, stating that Zhang was noted even in his day for being able to "make three wheels rotate as if they were one." More than one scholar has described Zhang as a polymath. However, some scholars also point out that Zhang's writing lacks concrete scientific theories. Comparing Zhang with his contemporary, Ptolemy (83-161) of Roman Egypt, Jin Guantao, Fan Hongye, and Liu Qingfeng state: Based on the theories of his predecessors, Zhang Heng systematically developed the celestial sphere theory. An armillary constructed on the basis of his hypotheses bears a remarkable similarity to Ptolemy's earth-centered theory. However, Zhang Heng did not definitely propose a theoretical model like Ptolemy's earth-centered one. It is astonishing that the celestial model Zhang Heng constructed was almost a physical model of Ptolemy's earth-centered theory. Only a single step separates the celestial globe from the earth-centered theory, but Chinese astronomers never took that step. Here we can see how important the exemplary function of the primitive scientific structure is. In order to use the Euclidean system of geometry as a model for the development of astronomical theory, Ptolemy first had to select hypotheses which could serve as axioms. He naturally regarded circular motion as fundamental and then used the circular motion of deferents and epicycles in his earth-centered theory. Although Zhang Heng understood that the sun, moon and planets move in circles, he lacked a model for a logically structured theory and so could not establish a corresponding astronomical theory. Chinese astronomy was most interested in extracting the algebraic features of planetary motion (that is, the length of the cyclic periods) to establish astronomical theories. Thus astronomy was reduced to arithmetic operations, extracting common multiples and divisors from the observed cyclic motions of the heavenly bodies.

Problem: Background: Blues Traveler is an American rock band formed in Princeton, New Jersey in 1987. The band's music covers a variety of genres, including blues rock, psychedelic rock, folk rock, soul, and Southern rock. It is known for extensive use of segues in their live performances, and was considered a key part of the re-emerging jam band scene of the 1990s, spearheading the H.O.R.D.E. touring music festival. Currently, the group comprises singer and harmonica player John Popper, guitarist Chan Kinchla, drummer Brendan Hill, bassist Tad Kinchla, and keyboardist Ben Wilson.
Context: On August 20, 1999, Bobby Sheehan was found dead in his New Orleans, Louisiana home, where he had been recording music with some friends the night before. Sheehan's death was ruled an accidental drug overdose, with cocaine, Valium, and heroin found in his system. The remaining members of Blues Traveler convened and agreed that Sheehan would have wanted them to continue as a band. Auditions for a new bassist were held in concert, and included Chan Kinchla's younger brother Tad, who was unanimously determined to be the best choice for the role. Additionally, an open call was sent for a permanent keyboard player, a role of which Sheehan had often been a proponent. In January 2000, Ben Wilson of the jump blues band Big Dave & the Ultrasonics was chosen, and has since become a central contributor to the band's songwriting. The band discarded their concept album material, instead releasing a smaller online EP, Decisions of the Sky: A Traveler's Tale of Sun and Storm, and went to work collectively composing a new set of songs with the new lineup. The resulting album was Bridge, which had the working title Bridge Outta Brooklyn as a tribute to Sheehan (with both the acronym B.O.B. and his nickname "Brooklyn Bobby"). The songs "Girl Inside My Head" and "Just for Me" received airplay, but the album's sales fell somewhat short of expectations. The live album What You and I Have Been Through and the compilation Travelogue: Blues Traveler Classics were both released in 2002.
Question: How did the new members work out for the band?
Answer: since become a central contributor to the band's songwriting.

Question: Victoria Wood, (19 May 1953 - 20 April 2016) was an English comedian, actress, singer and songwriter, screenwriter, producer and director. Wood wrote and starred in dozens of sketches, plays, musicals, films and sitcoms over several decades, and her live comedy act was interspersed with her own compositions, which she performed on the piano. Much of her humour was grounded in everyday life and included references to quintessentially "British" activities, attitudes and products. She was noted for her skills in observing culture and in satirising social classes.

On New Year's Day 2011 Wood appeared in a BBC drama Eric and Ernie as Eric Morecambe's mother, Sadie Bartholomew. For the 2011 Manchester International Festival, Wood wrote and directed That Day We Sang, a musical set in 1969 with flashbacks to 1929. It tells the story of a middle-aged couple who find love after meeting on a TV programme about a choir they both sang in 40 years previously. Although the characters are imaginary, the choir sang with the Halle Orchestra in Manchester's Free Trade Hall on a record that sold more than a million copies. Apart from the pieces on the 1929 recording (Purcell's "Nymphs and Shepherds" and the Evening Benediction from Hansel and Gretel) the score for the musical was written by Wood. On 22 December 2012 Wood was a guest on BBC Radio Two's Saturday morning Graham Norton Show. On 23 December BBC One screened Loving Miss Hatto, a drama written by Wood about the life of concert pianist Joyce Hatto, the centre of a scandal over the authenticity of her recordings and her role in the hoax. In April 2013, Wood produced a documentary about the history of tea named Victoria Wood's Nice Cup of Tea. In 2013 she played retired constable-turned-security-guard Tracy in BBC Scotland's Case Histories starring Jason Isaacs. She appeared in an episode of QI, broadcast on 13 December 2013, and around the same time made two return appearances on I'm Sorry I Haven't a Clue during the show's 60th series. In March 2014, Wood voiced the TV advertisement for the tour of the old set of Coronation Street. On 5 December 2014 Wood was a guest on BBC's The Graham Norton Show. On 26 December 2014, a television adaptation of That Day We Sang, starring Michael Ball and Imelda Staunton, was shown on BBC Two. In early 2015, Wood took part in a celebrity version of The Great British Bake Off for Comic Relief and was crowned Star Baker in her episode. She co-starred with Timothy Spall in Sky television's three-part television adaptation of Fungus the Bogeyman, which was first shown on 27, 28 & 29 December 2015, her last acting project and final role.
