Re: General Quiz

Hi bobbym,

The Answers #5502 (James Hargreaves) and #5503 (Moog synthesizer) are correct! Magnificent!

#5504.  Name the French chemist (September 28, 1852 – February 20, 1907)  who won the 1906 Nobel Prize in Chemistry for his work in isolating fluorine from its compounds. He was one of the original members of the International Atomic Weights Committee.

#5505.  Sir Isaac Newton's Philosophiæ Naturalis Principia Mathematica, known as the Principia, is published by the Royal Society of London. In it, Newton describes his theory of universal gravitation, explains the laws of mechanics and gives a formula for the speed of sound. The writing ofPrincipia Mathematica ushers in a tidal wave of changes in thought, significantly accelerating the scientific revolution by providing new and practical intellectual tools and becomes the foundation of modern physics. In which year was it published?

Re: General Quiz

Hi bobbym,

and

are both correct. Marvelous!

#5506. Name the instrument / gadget : A type of non-magnetic compass which is based on a fast-spinning disc and rotation of the Earth (or another planetary body if used elsewhere in the universe) to automatically find geographical direction.

#5507. Name the inventor : The electric-powered washing machine, invented in 1908, was a great time- and sweat-saving device—but only for those who could afford it and had regular electricity. He noticed that many in his Fort Worth community didn’t fit that description. In 1934, he purchased four electric washing machines and installed them in the same building. He charged people by the hour to clean their clothes in his “washateria,” now better known as a laundromat.

H bobbym,

The Answer #5509 is correct. Marvelous!

#5510. Name the German physicist (born 16 March 1929 in Rochlitz; died 15 January 1996 in Ulm) who developed the first working fiber-optical data transmission system in 1965. He received a patent for an "electro-optical transmission system utilizing lasers". From 1954 to 1979 he worked for the german Telefunken GmbH. Later, from 1979 to 1995, he was professor at the Technical University Munich. In 1982, he was awarded 'Fellow of the Institute of Electrical and Electronics Engineers (IEEE)'.

#5511.   Name the Scottish engineer and long-term inventor (21 August 1754 – 15 November 1839) . He was employed by the firm of Boulton and Watt and worked for them in Cornwall, as a steam engine erector for ten years, spending most of the rest of his life in Birmingham, England. He was the inventor of the oscillating cylinder steam engine, and gas lighting is attributed to him in the early 1790s, also the term "gasometer". However, Archibald Cochrane, ninth Earl of Dundonald, had already in 1789 used gas for lighting his family estate.

Re: General Quiz

Hi bobbym,

the Answers : #5510 - Manfred Börner and #5511 - William Murdoch (sometimes spelled Murdock).

The Answer #5510 is correct. Marvelous!

#5512. Name the British inventor (13 April 1771 – 22 April 1833) and mining engineer from Cornwall, England. Born in the mining heartland of Cornwall, He was immersed in mining and engineering from an early age. The son of a mining captain, he performed poorly in school, but went on to be an early pioneer of steam-powered road and rail transport. His most significant contribution was the development of the first high-pressure steam engine. He also built the first full-scale working railway steam locomotive.  On 21 February 1804 the world's first locomotive-hauled railway journey took place as his unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales.

#5513.  Name the German-Swiss chemist who is best known for inventing the fuel cell (1838) and his discoveries of guncotton and ozone (18 October 1799 – 29 August 1868). It was while doing experiments on the electrolysis of water at the University of Basel that he first began to notice a distinctive odor in his laboratory. This smell gave him the clue to the presence of a new product from his experiments. Because of the pronounced smell, he coined the term "ozone" for the new gas, from the Greek word "ozein", meaning "to smell".

Re: General Quiz

Hi bobbym,

The Answers : #5512 - Richard Trevithick and #5513 - Christian Friedrich Schönbein.

The Answer #5513 is correct. Excellent!

#5514. An autogyro, also known as gyroplane, gyrocopter, or rotaplane, is a type of rotorcraft which uses an unpowered rotor in autorotation to develop lift, and an engine-powered propeller, similar to that of a fixed-wing aircraft, to provide thrust. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing through the rotor disc to generate rotation. It was invented by the Spanish engineer Juan de la Cierva to create an aircraft that could fly safely at slow speeds. When was the autogyro first flown (at Cuatro Vientos Airfield in Madrid)?

#5515.  Name the American farmer who patented barbed wire, a product that forever altered the development of the American West (January 18, 1813 – October 9, 1906). (The Western United States, commonly referred to as the American West or simply the West, traditionally refers to the region comprising the westernmost states of the United States.)

#5516. Name the German inventor and industrialist (13 December 1816 – 6 December 1892). His name has been adopted as the SI unit of electrical conductance. He was also the founder of the electrical and telecommunications company named after him.

#5517. Name the British Army officer who was active in the development and adoption of the tank during the First World War  (21 October 1868 – 15 January 1951). He was also a war correspondent and author of several allegorical works of fiction on military themes, including a lastingly influential book on tactics and good practice. He is credited with having coined the word "tank" as a code-name for the first tracked, armoured fighting vehicles.

Re: General Quiz

Hi bobbym,

The Answer, #5517 (Sir Ernest Dunlop Swinton) is correct. Good work!

#5518.  Name the Scottish chemist and inventor of waterproof fabrics (29 December 1766 – 25 July 1843). He devoted all his spare time to science, particularly chemistry, and before he was twenty resigned his clerkship to take up the manufacture of chemicals. In this he was highly successful, inventing various new processes. His experiments with one of the by-products of tar, naphtha, led to his invention of waterproof fabrics, the essence of his patent being the cementing of two thicknesses of cloth together with natural (India) rubber, the rubber being made soluble by the action of the naphtha.

#5519.  Name the British engineer, best known for his invention of the steam turbine (13 June 1854 – 11 February 1931). He worked as an engineer on dynamo and turbine design, and power generation, with great influence on the naval and electrical engineering fields. He also developed optical equipment, for searchlights and telescopes.

After John Napier invented logarithms and Edmund Gunter created the logarithmic scales (lines, or rules) upon which slide rules are based, it was him who first used two such scales sliding by one another to perform direct multiplication and division; and he is credited as the inventor of the slide rule in 1622. He also introduced the "×" symbol for multiplication as well as the abbreviations "sin" and "cos" for the sine and cosine functions.

#5521. Name the English metallurgist  (18 February 1871 – 14 July 1948), usually credited with the invention of "rustless steel" (later to be called "stainless steel" in the anglophone world).
