Double Writing (Petty)
''A Declaration Concerning the newly invented Art of Double Writing'' was a pamphlet of 6 leaves, written by Sir William Petty (1623-1687) and first published in 1648. It contained information regarding his invention of the "Art of Double Writing", especially a claim for patent rights. It did not contain any information on what his invention exactly was. William Petty was educated in France and in Holland, and returned to England in 1646, to finish his education in the medical science at Oxford University. He was quite active in many fields of scientific discovery and inventions and developed an instrument for double-writing in 1647. It is mentioned in his first printed publication, titled '' The Advice to Hartlib'' (1647). Petty went to Ireland in 1652 to assist Oliver Cromwell in his conquest and arranged the Down Survey, a cadastral survey of Ireland, between 1654 and 1656. It would take twelve years, until Petty's next publication appeared in print: the '' Proceedings between ...

William Petty
Sir William Petty FRS (26 May 1623 – 16 December 1687) was an English economist, physician, scientist and philosopher. He first became prominent serving Oliver Cromwell and the Commonwealth in Ireland. He developed efficient methods to survey the land that was to be confiscated and given to Cromwell's soldiers. He also remained a significant figure under King Charles II and King James II, as did many others who had served Cromwell. Petty was also a scientist, inventor, and merchant, a charter member of the Royal Society, and briefly a Member of the Parliament of England. However, he is best remembered for his theories on economics and his methods of ''political arithmetic''. He is attributed with originating the laissez-faire economic philosophy. He was knighted in 1661. He was the great-grandfather of the 1st Marquess of Lansdowne (better known to history as the 2nd Earl of Shelburne), who served as Prime Minister of Great Britain, 1782–1783.

Wikisource
Wikisource is an online digital library of free-content textual sources on a wiki, operated by the Wikimedia Foundation. Wikisource is the name of the project as a whole and the name for each instance of that project (each instance usually representing a different language); multiple Wikisources make up the overall project of Wikisource. The project's aim is to host all forms of free text, in many languages, and translations. Originally conceived as an archive to store useful or important historical texts (its first text was the ), it has expanded to become a general-content library. The project officially began on November 24, 2003 under the name Project Sourceberg, a play on the famous Project Gutenberg. The name Wikisource was adopted later that year and it received its own domain name. The project holds works that are either in the public domain or freely licensed; professionally published works or historical source documents, not vanity products. Verification was initial ...

Robert Boyle
Robert Boyle (; 25 January 1627 – 31 December 1691) was an Anglo-Irish natural philosopher, chemist, physicist, alchemist and inventor. Boyle is largely regarded today as the first modern chemist, and therefore one of the founders of modern chemistry, and one of the pioneers of modern experimental scientific method. He is best known for Boyle's law, which describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. Among his works, '' The Sceptical Chymist'' is seen as a cornerstone book in the field of chemistry. He was a devout and pious Anglican and is noted for his writings in theology. Biography Early years Boyle was born at Lismore Castle, in County Waterford, Ireland, the seventh son and fourteenth child of The 1st Earl of Cork ('the Great Earl of Cork') and Catherine Fenton. Lord Cork, then known simply as Richard Boyle, had arrived in Dublin from England i ...

Epistle To The Hebrews
The Epistle to the Hebrews ( grc, Πρὸς Ἑβραίους, Pros Hebraious, to the Hebrews) is one of the books of the New Testament. The text does not mention the name of its author, but was traditionally attributed to Paul the Apostle. Most of the Ancient Greek manuscripts, the Old Syriac Peshitto and some of the Old Latin manuscripts have the epistle to the Hebrews among Paul's letters. However, doubt on Pauline authorship in the Roman Church is reported by Eusebius. Modern biblical scholarship considers its authorship unknown, written in deliberate imitation of the style of Paul, with some contending that it was authored by Priscilla and Aquila. Scholars of Greek consider its writing to be more polished and eloquent than any other book of the New Testament, and "the very carefully composed and studied Greek of Hebrews is not Paul's spontaneous, volatile contextual Greek". The book has earned the reputation of being a masterpiece.Powell, Mark A. ''Introducing the New Test ...

Pantograph
A pantograph (, from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other. Using the same principle, different kinds of pantographs are used for other forms of duplication in areas such as sculpting, minting, engraving, and milling. Because of the shape of the original device, a pantograph also refers to a kind of structure that can compress or extend like an accordion, forming a characteristic rhomboidal pattern. This can be found in extension arms for wall-mounted mirrors, temporary fences, pantographic knives, scissor lifts, and other scissor mechanisms such as the pantograph used on electric locomotives and trams. History The ancient Greek engineer Hero of Alexandria described pant ...

Duchy Of Bavaria
The Duchy of Bavaria (German: ''Herzogtum Bayern'') was a frontier region in the southeastern part of the Merovingian kingdom from the sixth through the eighth century. It was settled by Bavarian tribes and ruled by dukes (''duces'') under Frankish overlordship. A new duchy was created from this area during the decline of the Carolingian Empire in the late ninth century. It became one of the stem duchies of the East Frankish realm which evolved as the Kingdom of Germany and the Holy Roman Empire. During internal struggles of the ruling Ottonian dynasty, the Bavarian territory was considerably diminished by the separation of the newly established Duchy of Carinthia in 976. Between 1070 and 1180 the Holy Roman Emperors were again strongly opposed by Bavaria, especially by the ducal House of Welf. In the final conflict between the Welf and Hohenstaufen dynasties, Duke Henry the Lion was banned and deprived of his Bavarian and Saxon fiefs by Emperor Frederick Barbarossa. Fr ...
