Roy non hanno potuto non confessare che niente e' stato fatto mai che possa uguagliarlo. I personaggi citati da Piazzi sono l'Astronomo Reale di Greenwich Nevil Maskelyne (1732-1811) ed il Generale William Roy (?-1790) che diresse il programma della riunione delle reti di triangolazione francesi ed inglesi, cui lo stesso Piazzi aveva in parte assistito, durante il suo soggiorno in Francia.

Extractions: RAMSDEN (JESSE, 1735-1800, optician and mechanican 1 page, folio, partly mounted on an album leaf, integral address, recipient's endorsement (presumably autograph), postal marking, red wax seal in two portions, London, 24 August 1784 Jesse Ramsden was acknowledged to be the most skilful and capable instrument maker of the eighteenth century. He developed techniques that enabled him to increase greatly the precision of astronomical, surveying and navigational instruments. His greatest contribution to the technology of his time was probably the development of the dividing engine. He supplied many of the observatories of Europe with new achromatic telescopes equipped with accurately divided circles. His most famous work was a five-foot vertical circle for the Palermo observatory. He was elected a member of the Royal Society and of the Imperial Academy of St Petersburg and the Copley medal was awarded to him in 1795. George Goodriche (1764-1786), who died when only twenty-one years of age, laid the foundations of an important branch of stellar astronomy by discovering the first known short-period variable star (Algol) and also by establishing a remarkably accurate estimate of its period. He was elected a Fellow of the Royal Society shortly before his death. In 1783, Major-General William Roy (1726-1790), a royal engineer, was appointed by the government to carry a series of triangles from London to Dover, and connect them with the triangulation already made between Paris and the north coast of France, in order to determine the relative positions of the observatories of Paris and Greenwich. Roy selected Hounslow Heath for the base line, which was measured in the summer of 1784 three times over by means of cased glass tubing, seasoned pine rods, and a coffered steel chain, all made by Ramsden, and the discrepancy between the several measurements under three inches. The work excited considerable scientific and general interest.

Extractions: Jesse Ramsden (1735-1800) Jesse Ramsden, the son of a Yorkshire innkeeper, was born October 6, 1735. At the age of 16 he was apprenticed, first to a cloth worker and later to a scientific instrument maker in London. By the time he finished his apprenticeship he was highly skilled in engraving and his reputation rapidly increased after 1762 when he opened his own business. A few years later he married Sarah Dollond, the youngest sister of Peter Dollond. Ramsdens inventive genius led to the development of a new universal equatoreal, two new micrometers, and a new construction of eyeglasses. A telescopic eyepiece of his design is still used today. But his most important and well-known invention was a new engine for dividing mathematical instrument scales. While the best dividers at that time achieved an accuracy of no better than 3 seconds of arc, Ramsdens divider made it possible to inscribe lines accurate to ½ second. The British government awarded him a handsome premium for this invention. By 1789 he and his workmen had constructed nearly a thousand sextants. He made important improvements in theodolites and transits, invented a pyrometer to measure thermal expension, and a device for determining telescopic powers. His most famous work was a five-foot vertical circle for the Palermo Observatory. Another well-known instrument from his shop was the four-foot diameter theodolite delivered to General William Roy for his survey to link the Paris and Greenwich Observatory meridians. This was done with unprecedented accuracy owing largely to Ramsdens theodolite.

Extractions: Jesse Ramsden Scientific instrument maker and inventor, and maker of the first effective screw-cutting lathes. He was born at Salterhebble , Halifax on 6th October 1735. His father was an inn-keeper. He attended Heath Grammar School Originally working in the textile trade being apprenticed to a cloth-maker, he moved to London in 1755 and was apprenticed to a maker of scientific and mathematical instruments. By 1762, he had his own business in London, and was recognised as the most skilful designer of mathematical, astronomical, surveying and navigational instruments of his time. In 1765, he married Sarah, daughter of John Dolland His instruments were used by Lord Nelson, and the Duke of Wellington, and at the Piazzi Observatory in Palermo, the Dublin Observatory, and in 1793 he produced the largest telescope then in existence. His theodolite was used to produce the first Ordnance Survey of Britain. In 1773, he devised his circular dividing engine for graduating and marking the scales of scientific instruments accurate to 0.00001 inches, winning prizes from the Commissioners of Longitude . He was elected Fellow of the Royal Society in 1786, and received the Copley Medal in 1795.

Extractions: Máquinas de Ramsden, Holtz, Wimshurst e Bonetti Estas páginas são uma reorganização em português do material mais completo contido nas páginas em inglês aqui. O texto a seguir apresenta uma história do desenvolvimento das máquinas eletrostáticas, com uma breve descrição das máquinas mais importantes. O material foi compilado de várias fontes, na maior parte livros e artigos em inglês, francês e alemão do fim do século XIX e início do XX, assim como de minhas experiências. Na seção em inglês, podem ser encontradas mais figuras e referências sobre as origens de todo o material. Muitos dos "links" no texto abaixo apontam para páginas em inglês. Eu me interessei pelo assunto na adolescência, lendo velhos livros de física que ainda descreviam as máquinas mais importantes. Construí algumas máquinas pequenas, mas acabei deixando o assunto de lado por vários anos, apenas rodando as máquinas de tempos em tempos, que sempre me saudavam com algumas faíscas. Com o advento do WWW, achei que seria interessante montar uma página sobre máquinas eletrostáticas, o que fiz em 1996, e passei a estudar mais o assunto, voltando a construir e estudar estas máquinas. Pesquisando na Biblioteca de Obras Raras e no Museu da Escola de Engenharia da UFRJ, e através de contatos pela Internet, consegui levantar grande parte da história destas máquinas. As máquinas de atrito apenas realizam de forma mais prática, geralmente por rotação de um isolador atritado com um material adequado, o efeito conhecido desde a antiguidade, de que alguns materiais ficam eletrizados quando atritados. O contato reforçado pelo atrito provoca transferência de cargas entre os materiais, que são a seguir afastados, o que aumenta a tensão elétrica entre as cargas separadas.
