Book, Life of Sir Isaac Newton
... Life of Sir Isaac Newton...Life of Sir Isaac Newton...Life of Sir Isaac Newton Author: Brewster Publisher... Library Great Ocean Road Life of Sir Isaac Newton Brewster Label ...This item is from the ‘Pattison Collection’, a collection of books and records that was originally owned by the Warrnambool Mechanics’ Institute, which was founded in Warrnambool in 1853. By 1886 the Warrnambool Mechanics’ Institute (WMI) had grown to have a Library, Museum and Fine Arts Gallery, with a collection of “… choice productions of art, and valuable specimens in almost every branch and many wonderful national curiosities are now to be seen there, including historic relics of the town and district.” It later included a School of Design. Although it was very well patronised, the lack of financial support led the WMI in 1911 to ask the City Council to take it over. In 1935 Ralph Pattison was appointed as City Librarian to establish and organise the Warrnambool Library as it was then called. When the WMI building was pulled down in 1963 a new civic building was erected on the site and the new Warrnambool Library, on behalf of the City Council, took over all the holdings of the WMI. At this time some of the items were separated and identified as the ‘Pattison Collection’, named after Ralph Pattison. Eventually the components of the WMI were distributed from the Warrnambool Library to various places, including the Art Gallery, Historical Society and Flagstaff Hill. Later some were even distributed to other regional branches of Corangamite Regional Library and passed to and fro. It is difficult now to trace just where all of the items have ended up. The books at Flagstaff Hill Maritime Village generally display stamps and markings from Pattison as well as a variety of other institutions including the Mechanics’ Institute itself. RALPH ERIC PATTISON Ralph Eric Pattison was born in Rockhampton, Queensland, in 1891. He married Maude Swan from Warrnambool in 1920 and they set up home in Warrnambool. In 1935 Pattison accepted a position as City Librarian for the Warrnambool City Council. His huge challenge was to make a functional library within two rooms of the Mechanics’ Institute. He tirelessly cleaned, cleared and sorted a disarrayed collection of old books, jars of preserved specimens and other items reserved for exhibition in the city’s museum. He developed and updated the library with a wide variety of books for all tastes, including reference books for students; a difficult task to fulfil during the years following the Depression. He converted all of the lower area of the building into a library, reference room and reading room for members and the public. The books were sorted and stored using a cataloguing and card index system that he had developed himself. He also prepared the upper floor of the building and established the Art Gallery and later the Museum, a place to exhibit the many old relics that had been stored for years for this purpose. One of the treasures he found was a beautiful ancient clock, which he repaired, restored and enjoyed using in his office during the years of his service there. Ralph Pattison was described as “a meticulous gentleman whose punctuality, floorless courtesy and distinctive neat dress were hallmarks of his character, and ‘his’ clock controlled his daily routine, and his opening and closing of the library’s large heavy doors to the minute.” Pattison took leave during 1942 to 1945 to serve in the Royal Australian Navy, Volunteer Reserve as Lieutenant. A few years later he converted one of the Museum’s rooms into a Children’s Library, stocking it with suitable books for the younger generation. This was an instant success. In the 1950’s he had the honour of being appointed to the Victorian Library Board and received more inspiration from the monthly conferences in Melbourne. He was sadly retired in 1959 after over 23 years of service, due to the fact that he had gone over the working age of council officers. However he continued to take a very keen interest in the continual development of the Library until his death in 1969. The Pattison Collection, along with other items at Flagstaff Hill Maritime Village, was originally part of the Warrnambool Mechanics' Institute’s collection. The Warrnambool Mechanics’ Institute Collection is primarily significant in its totality, rather than for the individual objects it contains. Its contents are highly representative of the development of Mechanics' Institute libraries across Australia, particularly Victoria. A diversity of publications and themes has been amassed, and these provide clues to our understanding of the nature of and changes in the reading habits of Victorians from the 1850s to the middle of the 20th century. The collection also highlights the Warrnambool community’s commitment to the Mechanics’ Institute, reading, literacy and learning in the regions, and proves that access to knowledge was not impeded by distance. These items help to provide a more complete picture of our community’s ideals and aspirations. The Warrnambool Mechanics Institute book collection has historical and social significance for its strong association with the Mechanics Institute movement and the important role it played in the intellectual, cultural and social development of people throughout the latter part of the nineteenth century and the early twentieth century. The collection of books is a rare example of an early lending library and its significance is enhanced by the survival of an original collection of many volumes. The Warrnambool Mechanics' Institute’s publication collection is of both local and state significance. Life of Sir Isaac Newton Author: Brewster Publisher: William Tegg & Co.

... observations. Sir Isaac Newton (1643-1727) was a great figure...Isaac Newton, Author; Sam. Smith and Benj. Walford... corpuscular theory to explain his observations. Sir Isaac Newton (1643 ...This 300 year old book deals with the theory of light and colour and with investigations of the colours of thin sheets, 'Newton's rings', and diffraction of light. Newton uses a wave theory of light and his corpuscular theory to explain his observations. Sir Isaac Newton (1643-1727) was a great figure in the history of optical science. His classic 'Opticks' was first published in English in 1704. This Latin edition of 1706 was published to satisfy a wider scientific audience in Europe. Newton was Lucasian Professor at Cambridge 1669-1693 and a fellow of Trinity College. He achieved fame as a creative mathematician and for his law of universal gravitation which explains planetary motions. He retired from research in 1693 to become a government official in London.This book is highly significant as a milestone in the study of optics. Although not a very rare book, only one other copy is listed by WorldCat in an Australian institution.Latin edition of Newton's 'Optics' translated by Samuel Clarke. This copy is bound in full calf leather of the period, 348 pages, with fold-out figures plus a 24 page appendix 'Enumeratio linearum tertii ordinis' and a 43 page appendix 'Tractus de quadratura curvarum'. It is in outstandingly good condition.Inscribed on the fly leaf in pencil is that this is the 2nd edition, the first in Latin, and that Newton gave Clarke 500 pounds for the translation.refraction, optics, newton, reflection -

... isaac newton stevens... graham vincent joyce harold shields ian william bruce isaac ...The first Eltham Police Station was in the small building opposite Dalton Street rented from Mr Jarrold in 1857. In 1859 a dedicated Police Residence was built at 728 Main Road. A small weatherboard Police Station was attached to the side of the residence and a blue stone cell at the rear. Also on site were stables for the police horses. The Eltham Courthouse was built in 1860 and is the oldest public building in the district. In 1959 the Victoria Police purchased a house in Pryor Street to be refurbished as the Eltham Police Station. In 1961 the Police in Eltham move into Pryor Street refurbished buildings and office. During 2001 to 2002, the Eltham Police Station was demolished and a new complex constructed on site.

William Oughtred is credited with its invention in 1621, however many others including Isaac Newton have made improvements or modifications over the years. From 1625 to 1800 there were approximately 40 different styles brought forward. with the following 100 years sees over 250 designs created.There have been different versions and modifications to suit scientific, mathematical and engineering requirements. It is interesting to note that many of the buildings of the 19th and 20th centuries have been designed with the use of slide rules. Their use has declined in the last 25-30 years with the advent of computers and specialist calculators.While not directly linked in any way to the history of Warrnambool, this slide rule would have been a item in use by students doing maths at upper secondary level as well as other applications which would make it a familiar object to many people.Coated bamboo with sliding metal framed glass panel or cursor . The bamboo is in three sections with the middle section movable. It is marked in various graduated measurements mainly in dark blue but with some in green and red.It is inside a dark grey rectangular box with a slide off lid on one end.There is a celluloid panel on the back with a conversion table printed on it.

Instrument - Navigational Sextant, 1882-1890
... writings of Isaac Newton (1643–1727). Earlier links can be found... writings of Isaac Newton (1643–1727). Earlier links can be found ...A sextant is an astronomical instrument used to determine latitude and longitude at sea by measuring angular distances, especially the altitudes of the sun, moon, and stars. It is a doubly reflecting navigation instrument and used mainly by sailors to measure the angular distance between two visible objects. The name comes from the Latin sextans, or “sixth part of a unit,” because the sextant’s arc can be 60° or 120° of a circle depending on the model used. The primary use was to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. This angle and the time when it was measured is used in order to determine Greenwich Mean Time and hence longitude. Sighting the height of a landmark on land can also give a measure of distance from that object. History: The development of the sextant was as an improvement over the octant, an instrument designed to measure one's latitude. The octant was first implemented around 1731-present but can only measure angles up to 45°. As larger angles were needed to allow the measurement of lunar objects - moon, stars and the sun - at higher angles, the octant was superseded by the sextant. The sextant is a similar instrument but better made and allows larger angles from 60° to 120°. This improvement allows distances to be accurately calculated thereby giving longitude when used with a chronometer. The sextant was derived from the octant in 1757, eventually making all previous instruments used for navigational positioning obsolete. The sextant had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. It should be noted that the octant and quadrant are in the same family as they were, and all are, regarded as sextants. The sextant is representative of it's type and although not fully complete it demonstrates how 18th,19th and 20th century mariners determined their latitude and longitudinal to determine their position on a chart, allowing them to navigate there way across the world's oceans. It also demonstrates the skill and workmanship of the early instrument makers that operated scientific instrument businesses from London and other areas of England to provide most of the navigational instrumentation used by commercial and military navies of the time.Sextant with square, fitted box of polished wood, "Hezzanith" brand.

Octant, Late 18th to mid-19th century
... later in the unpublished writings of Isaac Newton (1643–1727... to the sextant was also found later in the unpublished writings of Isaac ...An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or “one-eighth of a circle,” for the Octant’s arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. History: The principle of the Octant as an instrument to measure ones latitude was first implemented around 1742-present but was superseded by the improvement of the octant to a sextant, a very similar instrument, better made and able to measure bigger angles 120°, allowing the measurement of Luna distances to give longitude when used with an accurate chronometer. The sextant started to appear around 1730 and had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a Sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. Henry Hemsley was a lesser-known instrument maker and optician working in London in the late 17th and early 18th century. However, it should be noted that there were two Henry Hemsley opticians and instrument makers around this period. (Henry Hemsley 1, 1786-89, who had premises at 85 Fleet St London and Henry Hemsley 2, 1828-56), whose workshop was at 135-138 Radcliff Highway London. Therefore, based on the inscribed workshop address Henry Hemsley 2 is responsible for making this example.The octant is representative of its type and although not fully complete it demonstrates how 18th and 19th-century mariners determined their latitude on a chart to navigate their way across the world's oceans in the 18th and 19th century. It also demonstrates the skill and workmanship of the early instrument makers that operated from London at this time and provided most of the navigational instrumentation use by commercial and military navies of the time.Octant, ebony wooden frame and handle.

This book of lectures on optics & geometry by Isaac Barrow, from 1674, was published in London in Latin to make it available to scholars across Europe. Isaac Barrow (1630-1677) was a graduate of Cambridge (BA 1649, MA 1652) and a mathematician. He became Lucasian Professor of Mathematics at Cambridge in 1663 and was tutor to Newton. This book includes Barrow's studies in geometric optics and the nature of light; material that would have encouraged Newton's better known research.This book has historical significance as it details the contemporary development of the knowledge of optics in the late 17th century. It is quite rare as no other copies are listed on WorldCat for Australia.Book, bound in full calf leather of the period, about optics and geometry by Isaac Barrow, in Latin. It has a title page, 12 introductory pages and 151 pages of text divided into 13 "lectures". There are 13 fold-out figures illustrating geometric constructs. It is in good condition except that the front cover is at present detached.optics, geometry, isaac barrow
