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.

Question: Joy Division were an English post-punk band formed in 1976 in Salford, Greater Manchester. Originally named Warsaw, the band consisted of singer-songwriter Ian Curtis, guitarist and keyboardist Bernard Sumner, bass player Peter Hook and drummer Stephen Morris. The band was formed by Sumner and Hook after attending a 4 June 1976 Sex Pistols concert at the Lesser Free Trade Hall in Manchester. While Joy Division's early recordings were heavily influenced by early punk, they evolved a unique sound, aided by producer Martin Hannett, which earned their reputation as pioneers of the post-punk movement.

Joy Division's style quickly evolved from their punk roots. Their sound during their early inception as Warsaw was described as generic and "undistinguished punk-inflected hard-rock". Critic Simon Reynolds observed how the band's originality only "really became apparent as the songs got slower", and their music took on a "sparse" quality. According to Reynolds, "Hook's bass carried the melody, Bernard Sumner's guitar left gaps rather than filling up the group's sound with dense riffage and Steve Morris' drums seemed to circle the rim of a crater." According to music critic Jon Savage, "Joy Division were not punk but they were directly inspired by its energy". In 1994 Sumner said the band's characteristic sound "came out naturally: I'm more rhythm and chords, and Hooky was melody. He used to play high lead bass because I liked my guitar to sound distorted, and the amplifier I had would only work when it was at full volume. When Hooky played low, he couldn't hear himself. Steve has his own style which is different to other drummers. To me, a drummer in the band is the clock, but Steve wouldn't be the clock, because he's passive: he would follow the rhythm of the band, which gave us our own edge." By Closer, Curtis had adapted a low baritone voice, drawing comparisons to Jim Morrison of the Doors (one of Curtis's favourite bands). Sumner largely acted as the band's director, a role he continued in New Order. While Sumner was the group's primary guitarist, Curtis played the instrument on a few recorded songs and during a few shows. Curtis hated playing guitar, but the band insisted he do so. Sumner said, "He played in quite a bizarre way and that to us was interesting, because no one else would play like Ian". During the recording sessions for Closer, Sumner began using self-built synthesisers and Hook used a six-string bass for more melody. Hannett "dedicated himself to capturing and intensifying Joy Division's eerie spatiality". Hannett believed punk rock was sonically conservative because of its refusal to use studio technology to create sonic space. The producer instead aimed to create a more expansive sound on the group's records. Hannett said, "[Joy Division] were a gift to a producer, because they didn't have a clue. They didn't argue". Hannett demanded clean and clear "sound separation" not only for individual instruments, but even for individual pieces of Morris's drumkit. Morris recalled, "Typically on tracks he considered to be potential singles, he'd get me to play each drum on its own to avoid any bleed-through of sound". Music journalist Richard Cook noted that Hannett's role was "crucial". There are "devices of distance" in his production and "the sound is an illusion of physicality".
