Anatomy * Antonio Scarpa publishes ', the first work to give an accurate depiction of cardiac innervation, and to include the discovery that the inner ear is filled with fluid. Astronomy * Ernst Chladni publishes ''Über den Ursprung der von Pallas gefundenen und anderer ihr ähnlicher Eisenmassen und über einige damit in Verbindung stehende Naturerscheinungen'' ("On the Origin of the Pallas Iron and Others Similar to it, and on Some Associated Natural Phenomena") in which he proposes that meteorites have their origins in outer space. * Completion of the Radcliffe Observatory for the University of Oxford, Thomas Hornsby being the first observer. Biology * Erasmus Darwin publishes the first edition of ''Zoonomia'', a medical work in two volumes that touches upon proto-evolutionary concepts, notably arguing that all extant organisms are descended from one common ancestor.

Jurij Vega
Baron Jurij Bartolomej Vega (also spelled Veha; ; ; born Vehovec, March 23, 1754 – September 26, 1802) was a Slovene mathematician, physicist, and artillery commissioned officer. Early life Born into a farmer's family in the small village of Zagorica, east of Ljubljana in present-day Slovenia, Jurij Vega was six years old when his father, Jernej Veha, died. He was first educated in Moravče and then attended high school for six years (1767–1773) at the Jesuit College in Ljubljana ('), where he studied Latin, Greek, religion, German, history, geography, science, and mathematics. At the time, the college had around 500 students. He was a schoolmate of Anton Tomaž Linhart, the Slovenian writer and historian. Vega completed high school in 1773 at the age of 19. Afterward, he studied at the Lyceum of Ljubljana (''Licej v Ljubljani'') and became a navigational engineer in 1775. A copy of his ''Tentamen philosophicum''—a list of questions for his comprehensive examination— ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cotton Gin
A cotton gin—meaning "cotton engine"—is a machine that quickly and easily separates cotton fibers from their seeds, enabling much greater productivity than manual cotton separation.. Reprinted by McGraw-Hill, New York and London, 1926 (); and by Lindsay Publications, Inc., Bradley, Illinois, (). The separated seeds may be used to grow more cotton or to produce cottonseed oil. Handheld roller gins had been used in the Indian subcontinent since at earliest 500 and then in other regions. The Indian worm gear, worm-gear roller gin was invented sometime around the 16th century and has, according to Lakwete, remained virtually unchanged up to the present time. A modern mechanical cotton gin was created by English-American inventor Eli Whitney in 1793 and patented in 1794. Whitney's gin used a combination of a wire screen and small wire hooks to pull the cotton through, while brushes continuously removed the loose cotton lint to prevent jams. It revolutionized the cotton indus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an sufficiency of disclosure, enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private la ...

Eli Whitney
Eli Whitney Jr. (December 8, 1765January 8, 1825) was an American inventor, widely known for inventing the cotton gin in 1793, one of the key inventions of the Industrial Revolution that shaped the economy of the Antebellum South. Whitney's invention made upland short cotton into a profitable crop, which strengthened the economic foundation of slavery in the United States and prolonged the institution. Despite the social and economic impact of his invention, Whitney lost much of his profits in legal battles over patent infringement for the cotton gin. Thereafter, he turned his attention to securing contracts with the government in the manufacture of muskets for the newly formed United States Army. He continued making arms and inventing until his death in 1825. Early life and education Whitney was born in Westborough, Massachusetts, on December 8, 1765, the eldest child of Eli Whitney Sr., a prosperous farmer, and his wife Elizabeth Fay, also of Westborough. The younger Eli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

James Watt
James Watt (; 30 January 1736 (19 January 1736 OS) – 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1776, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. At the time engineers such as John Smeaton were aware of the inefficiencies of Newcomen's engine and aimed to improve it. Watt's insight was to realise that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. Eventually, he adapted his engine to produce rot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
