Cracroft Caverns
Cracroft Caverns, also known as the Cashmere Caverns, are a series of large chambers in the hill of the Cashmere suburb of Christchurch, New Zealand. Constructed secretly during the Second World War in response to the Japanese threat, they were intended to house operational headquarters in the event of attack. The military commandeered the Cracroft Wilson estate, founded by Sir John Cracroft Wilson in 1854, for their Southern Group headquarters, and work on the tunnels began in 1942. Railways were built for access and for the removal of waste soil. The largest cavern was 7 metres high, 10 metres wide and 30 metres long. Prestressed concrete was used to line the caverns. Officers based in the estate house would come down stairs into the tunnels, while others were to enter through the access tunnels. Construction came to a sudden halt in 1944 as the threat of invasion receded, even though work on the bunkers was nearly complete. The weekend before the military left the estate, fir ...

Cashmere, New Zealand
Cashmere is a suburb which rises above the southern end of the city of Christchurch in New Zealand's South Island. Geography Cashmere is situated on the north side of the Port Hills, immediately above the southern terminus of Colombo Street and approximately five kilometres south of the city centre. The suburb's location on the Port Hills offers it a commanding view over the rest of the mostly flat city. Cashmere's proximity to the rest of the Port Hills has also made it a favourite for recreation, with the upper reaches of the suburb dominated by Victoria Park with its multiple bike and walking tracks and connections to further tracks running the length of the Port Hills. Above Victoria Park is Sugarloaf, a peak which is the location of a transmission tower used for local radio and TV stations. The Ōpāwaho / Heathcote River marks the northern extent of the suburb, flowing roughly along the base of the Port Hills. History Cashmere takes its name from Sir John Cracroft Wilso ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Cracroft Wilson
Sir John Cracroft Wilson (21 May 1808 – 2 March 1881), also known as Nabob Wilson, was a British-educated civil servant in India, farmer and politician in New Zealand. Early life John Cracroft Wilson was born in Onamore, India, the son of Alexander Wilson , a judge in the Madras Civil Service and a noted botanist, and Elizabeth Clementina Wilson ( Cracroft). His mother was from a long established family—the Cracrofts of Hackthorn Hall in Lincolnshire. Her family name was given to him as a second Christian name, a custom that has been followed by the family ever since; they are thus known as the Cracroft Wilsons. He was educated at Haileybury College and Brasenose College, Oxford. He returned to India in 1828 and entered the Bengal Civil Service as a cadet, advancing to become a magistrate. Advancing to the rank of assistant commissioner to William Sleeman, he was assigned to the Doab region in 1832 where he investigated men who were accused of thuggee. He married Elizabeth ...

Christchurch City Libraries
Christchurch City Libraries is operated by the Christchurch City Council and is a network of 21 libraries and a mobile book bus. Following the 2011 Christchurch earthquake the previous Christchurch Central Library building was demolished, and was replaced by a new central library building in Cathedral Square, ''Tūranga'', which opened in 2018. Early history The library began as the Mechanics' Institute in 1859, when 100 subscribers leased temporary premises in the then Town Hall. The collection consisted of a few hundred books. By 1863, with the help of a grant from the Provincial Government, the Mechanics' Institute opened a building on a half-acre of freehold land on the corner of Cambridge Terrace and Hereford Street, purchased the year before at a cost of £262.10.0. This site was to remain the home of the library until 1982. Debt, dwindling subscribers and other problems forced the institute to hand over the building to the Provincial Government in 1873. By this time t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring Laser Gyroscope
A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation. Interference between the counter-propagating beams, observed externally, results in motion of the standing wave pattern, and thus indicates rotation. Description The first experimental ring laser gyroscope was demonstrated in the US by Macek and Davis in 1963. Various organizations worldwide subsequently developed ring-laser technology further. Many tens of thousands of RLGs are operating in inertial navigation systems and have established high accuracy, with better than 0.01°/hour bias uncertainty, and mean time between failures in excess of 60,000 hours. Ring laser gyroscopes can be used as the stable elements (for one degree of freedom each) in an ine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2011 Christchurch Earthquake
A major earthquake occurred in Christchurch on Tuesday 22 February 2011 at 12:51 p.m. local time (23:51 UTC, 21 February). The () earthquake struck the entire of the Canterbury region in the South Island, centred south-east of the central business district. It caused widespread damage across Christchurch, killing 185 people, in New Zealand's fifth-deadliest disaster. Christchurch's central city and eastern suburbs were badly affected, with damage to buildings and infrastructure already weakened by the magnitude 7.1 Canterbury earthquake of 4 September 2010 and its aftershocks. Significant liquefaction affected the eastern suburbs, producing around 400,000 tonnes of silt. The earthquake was felt across the South Island and parts of the lower and central North Island. While the initial quake only lasted for approximately 10 seconds, the damage was severe because of the location and shallowness of the earthquake's focus in relation to Christchurch as well as ...
