He was also ordered by the Board of Longitude to investigate the comparative accuracy of two additional means of longitude determination based upon observations of the satellites of Jupiter and on occultations of stars by the moon.

He was further entrusted with the testing of a marine chair designed by a certain Mr. Christopher Irwin, which he found to be quite impracticable for assisting observations made at sea. He also presented a memorial in which he proposed that the practical application of the method could be facilitated by the preparation of a nautical ephemeris with auxiliary tables and explanations.

These plans crystallized less than two years later with the publication of the Nautical Almanac for He continued to superintend the ever-increasing work of the computers and comparers of the annual Nautical Almanac until his death more than forty years later. It is still a useful navigational aid even though the lunar distance tables themselves became obsolete by the beginning of the twentieth century, mainly as a result of the exceptionally high degree of reliability of chronometers.

Schiehallion, in Scotland. By observing the slight difference in the zenith distances of certain stars at two observing stations on the north and south faces of the mountain, and making due allowance for the effect of their latitude difference by means of geodetic measurements, Maskelyne identified the residual displacement of This was the first convincing experimental demonstration of the universality of gravitation, in the sense that it operates not only between the bodies of the solar system but also between the elements of matter of which each body is composed.

With the aid of his friend Charles Hutton and John Playfairwho estimated the density of the rocks and total mass of that mountain relative to the mass of the earth, Maskelyne concluded the mean density of the earth to be between 4. No definitive biography of Maskelyne has been written but accounts of his life and work are to be found in standard encyclopedic works such as Encyclopaedia Britannica8th ed.

Edmund Sr. Nevil was still being educated at Westminster School when his mother Elizabeth died in After this Nevil boarded at Vincent Bourne's house in Westminster while he continued his school education.

Just before the death of his mother his interest in astronomy had begun after seeing the eclipse of 25 July Maskelyne writing about his school education said see for example [ 1 ] :- Great mathematicians have become astronomers from the facility mathematics gave them in the attainment of astronomy; but here the love of astronomy was the motive of application to mathematics without which our astronomer soon found he could not make the progress he wished in his favourite science; in a few months, without any assistance he made himself master of the elements of geometry and algebra.

With these helps he soon read the principal books in astronomy and optics and also in The considerable progress he had made in these sciences led him naturally to the University of Cambridge In the summer of the following year he moved to Pembroke College and in he moved again, this time to Trinity College where he studied the mathematical tripos and graduated with a B.

He was ranked as seventh wrangler in the mathematical tripos. As part of his move to gain a fellowship, he was ordained a minister inbecoming a curate at Chipping Barnet in Hertfordshire. Then he became a fellow of Trinity College, Cambridge in By this time he was in close contact with James Bradley who was the Savilian professor of astronomy at Oxford and the Astronomer Royal.

Maskelyne learned much from working with Bradley and assisted him in producing a table of refractions. With Bradley as one of his supporters, on 27 April Maskelyne was admitted to the Royal Society of Londonhis recommendation describing him as On 14 July the Royal Society agreed to send Maskelyne to the island of St Helena to observe a transit of Venus which would take place on 6 June Maskelyne had earlier proposed that the nevil maskelyne biography template expedition should try to nevil maskelyne biography template the parallax of the star Sirius.

An extract from Maskelyne's parallax proposal is at THIS LINK This Venus transit was important since accurate measurements would allow the distance from the Earth to the Sun to be accurately measured and the scale of the solar system determined. He set sail on the ship Prince Henry on 18 January During the voyage he experimented with the lunar position method of determining longitude using the lunar tables produced by Tobias Mayer.

He arrived in St Helena on 6 April in plenty of time to find a good site for observing and to set up his instruments. Sadly, the 6 June was cloudy and he was unable to make measurements of the transit. He spent several months on St Helena trying to compute the parallax of Sirius but eventually decided that his instruments were faulty. Disappointed, Maskelyne set sail for England on the ship Warwick in February Maskelyne entered St Catharine's College, Cambridge ingraduating as seventh wrangler in Originally pursuing his career as a Church of England minister, he was Rector of Shrawardine in Shropshire from to and then Rector of North Runcton in Norfolk from In he was elected a Fellow of the Royal Society of Edinburgh.

Maskelyne's younger sister, Margaretmarried Robert Clive. Maskelyne is buried in the churchyard of St Mary the Virginthe parish church of the village of PurtonWiltshire, England. In the Royal Society appointed Maskelyne as an astronomer on one of their expeditions to observe the transit of Venus. This was an important observation since accurate measurements would allow the accurate calculation of Earth's distance from the Sun, which would in turn allow the actual rather than the relative scale of the Solar System to be calculated.

This would allow, it was argued, the production of more accurate astronomical tables, in particular those predicting the motion of the Moon. Bad weather prevented observation of the transit, but Maskelyne used his journey to trial a method of determining longitude using the position of the moon, which became known as the lunar distance method.

In the Board of Longitude sent Maskelyne to Barbados in order to carry out an official trial of three contenders for a Longitude reward.

He was to carry out observations on board ship and to calculate the longitude of the capital, Bridgetown by observation of Jupiter 's satellites. The three methods on trial were John Harrison 's sea watch now known as H4Tobias Mayer 's lunar tables and a marine chair made by Christopher Irwin, intended to help observations of Jupiter's satellites on board ship.

Both Harrison's watch and lunar-distance observations based on Mayer's lunar tables produced results within the terms of the Longitude Actalthough the former appeared to be more accurate. Harrison's watch had produced Bridgetown's longitude with an error of less than ten miles, while the lunar-distance observations were accurate to within 30 nautical miles.

Maskelyne reported the results of the trial to the Board of Longitude on 9 February The Commissioners understood that the timekeeping and astronomical methods of finding longitude were complementary. The lunar-distance method could more quickly be rolled out, with Maskelyne's proposal that tables like those in his "The British Mariner's Guide" be published for each year.

This proposal led to the establishment of The Nautical Almanacthe production of which, as Astronomer Royal, Maskelyne oversaw. Taking even occasional astronomical observations was also the only way to check that a timekeeper was keeping good time over the course of a long voyage.

The Commissioners also needed to know that more than one sea watch could be made, and that Harrison's methods could be communicated to other watchmakers. Although Harrison and his son later accused Maskelyne of bias against the timekeeping method, charges repeated by authors such as Dava Sobel and Rupert GouldMaskelyne never submitted a method or an idea of his own for consideration by the Board of Longitude.

He was to play a significant role in having marine timekeepersas well as the lunar-distance method, developed, tested and used on board voyages of exploration. Since the observations that fed into the Nautical Almanac were made at the Royal Observatory, Greenwichthe Greenwich meridian became the reference for measurements of longitude in the Royal Navy, and on British Admiralty charts.

It was subsequently chosen for adoption as the international Prime Meridian in Maskelyne took a great interest in various geodetical operations, including the measurement of the length of a degree of latitude in Maryland and Pennsylvania[ 20 ] [ 13 ] executed by Mason and Dixon in —and later the determination of the relative longitude of Greenwich and Paris.

This triangulation was the beginning of the great trigonometrical survey which was subsequently extended all over Britain.
