Extractions: Important Astronomers, their Instruments and Discoveries by Paul M. Rybski Part 3 The Story of the Earliest Reflecting Telescopes Italian monk Niccolo Zucchi proposed (1616) a concave mirror to replace the refractor's objective lens. The poor shape of his mirror, added to the lack of means of viewing the image without blocking the mirror, caused Zucchi to give up on the idea. French astronomer Marin Mersenne proposed (1630) developing a reflector that used two concave mirrors, the smaller secondary mirror to reflect the light through a hole in the center of the larger primary mirror. Unfortunately, he was dissuaded from working on it further by French mathematician René Descartes. Scottish mathematician James Gregory proposed (1663) a two-mirror reflector with a concave, paraboloidal primary and concave, ellipsoidal secondary, the secondary bringing light to a focus inside the telescope tube and a convex eyepiece delivering light to the eye. Sadly, he did not construct a working version because he could not find a craftsperson skilled enough to grind and polish the required mirrors. English mathematician and physicist Isaac Newton (1648-1727) designed and constructed a two-mirror reflector (1668), a concave primary delivering a converging cone of light to a flat secondary mounted at a 45° angle to the optical axis which directed the light to a focus outside the tube where an eyepiece could be placed. A second such reflector was built and presented to the Royal Society in January of 1672.

Extractions: [Note: World Population in 1700 was about 625 million; in 1980 it was over 4 billion] Machine Tools The Newcomen and Watt Steam Engines Thomas Newcomen (1663-1729) was an English blacksmith, who invented an atmospheric engine. Steam was admitted to a cylinder, condensed by a jet of cold water, and the vacuum created on the inside of the cylinder allowed atmospheric pressure to operate a piston, which was forced downward on its working stroke. In partnership with Thomas Savery who had patented a steam pump along similar lines in 1698, Newcomen and his other partner, John Calley, built their first engine on the site of a water-filled mine shaft in 1712. Newcomen engines were slow and inefficient, but they were better than any other device yet invented for pumping water out of mines. The Steam Locomotive and the Steamboat Watt's patent for the separate condenser covered the use of high pressure steam, but since he was fearful of boiler explosions and bursting pipes he refused to develop such an engine. He even went so far as to suppress the working model of a high pressure engine, made by his assistant William Murdock in 1785. When Watt's patent expired in 1800, there were other inventors in England and America who advocated the use of high pressure steam. Richard Trevithick (1771-1833) had gained his experience around steam engines in the Cornish mines. By 1801, he had perfected his designs for a cylindrical boiler and high pressure engine and built several full size steam carriages which were patented and run on the English roads. During the first decade of the l9th Century, he built several more steam carriages, known as locomotives, which were used for hauling coal and ore out of the mines.
Small Telescopes In Research And Education problem of casting strong mechanical mountings suitable for large telescopes wassolved by the use of the steam hammer invented by James Nasmyth (18081890). http://www.darksky.org/~ida/gnat/information/White Papers/kochhar.htm
Extractions: Koramangala, Bangaore 500 034, India (Paper presented at UN sponsored meeting in Bonn Germany Sep 1996) Historical Perspective About 200 years ago. a 9.5 cm aperture telescope was called a large telescope. London was then the centre of the world optical trade with John Dollond (1706-61), his son-in-law Jess Ransden (d.1800) and son Peter Dollond (d.1820) as the leading telescope makers. At that time, it was not possible to make good quality flint glass blanks of larger size, and the lenses were ground by trial and error. Credit for providing a scientific basis for optical engineering as well as for making large sized lens telescopes goes to Munich based Joseph Fraunhofer (1787-1826), who started his career as an 11 year old orphan in virtual bondage at an optics shop and rose to such eminence that on his death he received a state funeral. Originally, reflecting telescopes were made from the unwieldy speculum metal, an alloy of copper and tin. The invention, in 1856, of the silver-on-glass technique by the chemist Justus von Liebig (1803-1873) in a different context made it possible to make large, low-weight astronomical mirrors. the problem of casting strong mechanical mountings suitable for large telescopes was solved by the use of the steam hammer invented by James Nasmyth (1808-1890). With the advent of large telescopes, the centre of astronomical activity shifted from Europe to the USA, which had the requisite clear skies, funds, and a desire for intellectual leadership. In recent time, advance in technology, telecommunications, and international cooperation have freed observatories from the limitations of national boundaries and made it possible to collectively install large telescopes at globally selected sites.

Extractions: The Industrial Revolution Towards the end of 18th century, there was an increase in technical and economic development which resulted in the domestic and agrarian economy being replaced by one which was dominated by machinery and manufacturing. The invention of the steam engine in 1712 was a major innovation, opening up development in this period. Originally developed for draining mines by Thomas Newcomen , it was rapidly adapted for use in factories and on the railways by James Watt Richard Arkwright Samuel Crompton , and Richard Trevithick The conditions in Britain were favourable for such changes: The innovations included: New materials : iron and steel New energy sources : coal and the steam-engine : particularly in the textile industry New transportation systems : steam trains, canals, and better roads

LITTLE ENGINEERING GIANT Brunel brought the problem to James Nasmyth, (18081890) (See More Great Engineers on this web site) who, in solving Brunel's problem, invented the steam http://www.engr.mun.ca/~gpeters/5101brun.html
Extractions: Peter Hay, in his book on Brunel, [1] quotes from Nicholson's British Encyclopaedia, 1909: "Engineers are extremely necessary for these purposes; wherefore it is requisite that, besides being ingenious, they should be brave in proportion." Thus we are advised that engineers must not only be smart; they must also have nerve. We will spend a little time on such an engineer, Isambard Kingdom Brunel, who was involved in many projects. You may recall that he was mentioned in the "Out of the Fiery Furnace" video, in connection with his building of the iron ship "Great Britain", and we will see more of that shortly. He is interesting for several reasons. In his day, he ranked among the top half dozen engineers working in that heady Victorian period when the results of the Industrial Revolution were "transforming society". You may recall words said by Michael Charlton in the video just mentioned, which were published in "The Engineer" in 1910, and quoted in Rolt's biography of Brunel [14]: "In all that constitutes an engineer in the highest, fullest and best sense, Brunel had no contemporary, no predecessor.
