Some context: Napalm Death are a British extreme metal band formed in Meriden, West Midlands, England, in 1981. While none of its original members remain in the group since December 1986, the lineup of vocalist Mark "Barney" Greenway, bassist Shane Embury, guitarist Mitch Harris and drummer Danny Herrera has remained consistent of the band's career since 1992's Utopia Banished, although, from 1989 to 2004, Napalm Death were a five-piece band after they added Jesse Pintado as the replacement of one-time guitarist Bill Steer; following Pintado's departure, the band reverted to a four-piece rather than replace him. Napalm Death are credited as pioneers of the grindcore genre by incorporating elements of crust punk and death metal, using a noise-filled sound that uses heavily distorted, down-tuned guitars, grinding overdrive bass, high speed tempo, blast beats, and vocals which consist of incomprehensible growls, or high-pitched shrieks, extremely short songs, fast tempos, and sociopolitical lyrics. The band's debut album Scum, released in 1987 by Earache Records, proved substantially influential throughout the global metal community.
In April 2005, their next album The Code Is Red...Long Live the Code was released. It features guest appearances from Jeffrey Walker (Carcass), Jamey Jasta (Hatebreed vocalist) and Jello Biafra (formerly of Dead Kennedys, and Lard among many other bands). The album continued the band's progressive approach to their brutal brand of extreme metal, with their trademark grindcore sound retained. Also in 2005, Embury and Herrera joined the extreme metal band Anaal Nathrakh for one tour. Napalm Death finished recording their follow-up album titled Smear Campaign in June 2006, and it was released on 15 September 2006 to strong reviews from fans and critics alike. The main lyrical focus is criticism of the United States Government and other governments who are strongly religious. The album features a guest appearance by Anneke van Giersbergen, vocalist for the Dutch rock band The Gathering. There is a limited edition digipak version of Smear Campaign, which has two new songs, "Call That an Option?" and "Atheist Runt". They played a series of headline shows in support of the release including the Koko in Camden with Gutworm. In early 2006 Napalm Death headlined a tour with Kreator, A Perfect Murder, and Undying. On 27 August 2006, Jesse Pintado died in a hospital in the Netherlands due to liver failure, prompting Mitch Harris to express his sadness at the loss of someone he thought of as "a brother" on the band's official website. After the Smear Campaign tour, the band did a 2007 "World Domination Tour". Bassist Shane Embury is currently working on a project with Mick Kenney of Anaal Nathrakh, their work together will be released on FETO Records at the end of 2007. In November 2008, Napalm Death's fourteenth studio album, entitled Time Waits for No Slave, leaked onto the internet; it was officially released on 23 January 2009. Similar to Smear Campaign, Time Waits For No Slave also had a digipak version containing two extra songs ("Suppressed Hunger" and "Omnipresent Knife In Your Back").

Some context: Shen Kuo (Chinese: Chen Gua ; 1031-1095), courtesy name Cunzhong (Cun Zhong ) and pseudonym Mengqi (now usually given as Mengxi) Weng (Meng Xi Weng ), was a Han Chinese polymathic scientist and statesman of the Song dynasty (960-1279). Excelling in many fields of study and statecraft, he was a mathematician, astronomer, meteorologist, geologist, zoologist, botanist, pharmacologist, agronomist, archaeologist, ethnographer, cartographer, encyclopedist, general, diplomat, hydraulic engineer, inventor, academy chancellor, finance minister, governmental state inspector, poet, and musician.
Since the time of the engineer and inventor Ma Jun (c. 200-265), the Chinese had used the south-pointing chariot, which did not employ magnetism, as a compass. In 1044 the Collection of the Most Important Military Techniques (Wu Jing Zong Yao ; Wujing Zongyao) recorded that fish-shaped objects cut from sheet iron, magnetized by thermoremanence (essentially, heating that produced weak magnetic force), and placed in a water-filled bowl enclosed by a box were used for directional pathfinding alongside the south-pointing chariot. However, it was not until the time of Shen Kuo that the earliest magnetic compasses would be used for navigation. In his written work, Shen Kuo made the first known explicit reference to the magnetic compass-needle and the concept of true north. He wrote that steel needles were magnetized once they were rubbed with lodestone, and that they were put in floating position or in mountings; he described the suspended compass as the best form to be used, and noted that the magnetic needle of compasses pointed either south or north. Shen Kuo asserted that the needle will point south but with a deviation, stating "[the magnetic needles] are always displaced slightly east rather than pointing due south." Shen Kuo wrote that it was preferable to use the twenty-four-point rose instead of the old eight compass cardinal points -- and the former was recorded in use for navigation shortly after Shen's death. The preference of use for the twenty-four-point-rose compass may have arisen from Shen's finding of a more accurate astronomical meridian, determined by his measurement between the pole star and true north; however, it could also have been inspired by geomantic beliefs and practices. The book of the author Zhu Yu, the Pingzhou Table Talks published in 1119 (written from 1111 to 1117), was the first record of use of a compass for seafaring navigation. However, Zhu Yu's book recounts events back to 1086, when Shen Kuo was writing the Dream Pool Essays; this meant that in Shen's time the compass might have already been in navigational use. In any case, Shen Kuo's writing on magnetic compasses has proved invaluable for understanding China's earliest use of the compass for seafaring navigation.
