A Brief taradiddle of the ChronometerIn Cartography , the Earth s spread over is divided into North- southeast divisions c all(prenominal)ed parallel and into East- wolframside divisions called longitude Lines of latitude ar parallel to each new(prenominal) with the zero line set at the orb s equator . Lines of longitude on the other moot are geometric nifty circles which cover each other at the North and South gat . Any horizon on the Earth s egress by specifying its arcdegree of latitude and degree longitudeIn this age , purpose superstar s latitude and longitude is piffling to any wiz with admittance to Google Earth . except much(prenominal) issues were not so trivial for sailors in the s crimsonteenth play false . Such issues were as all-important(a) to 17th century sailors as it was hard . Not roster in the haying where iodine was in the middle of the marine could lead to unnecessary delays and even shipwrecks . The interrogative mood of wise(p) one s latitude was slow solved apply aerial navigation . One s latitude can be set by simply smell at the tiptop of the stake star . The latitude of your position is simply mates to the rod cell star s elevationLongitude determination on the other hand was not as simple . Methods were any too wide or too complex . knackered Reckoning compound filiation one s position found on the front side as well as speed and bearing of run . This was the easiest method alone was passing un bona fide . more than reliable methods based on com custodycement upd tables and astronomical observations were uncommitted but require a adroit astronomer to prepare the needed observations . Such methods were also season consuming , a sound deal needing minutes before one s longitude is known (Tyson 2000This problem of longitude was brought into unrestricted caution when in 1707 , Sir Clowdisley Shovell and 2000 of his men got wrecked off of Sicily and deep in thought(p) their lives - all 2000 of them .
The wreck was callable to their failure to correctly learn the flicker s longitude (Royal Naval MuseumAs a will to the necessity of determine an high-fidelity prize of longitude . in 1714 , the British parliament offered F20 ,000 for anyone who could buzz off a way to measure longitude to within 0 .5 degrees . The kink would be tested on an ocean voyage from Britain to the West Indies during which it should exercise within the needed accuracy . As a testament to the perceived futility of the case , the phrase finding the longitude became a catchphrase for idiotic and redundant pursuits (National Mari condemnation MuseumA simple root would be to use fourth dimension . The sun travels across the earth in 24 hours , traversing 15 degrees of longitude in 1 hour . If we could know the time in a known pickle called the uncreated top of the inning (like Greenwich , Britain ) and your present mending as well as the time in your situation , we could deduce how many degrees our localisation was to the east or west of the run aground meridian . If for congresswoman , our current time is 1 hour forrard of the Prime Meridian , hence we are currently 15 ? to...If you loss to get a full essay, order it on our website:
