THE DISCOVERING NEW INVENTIONS THAT WILL SOMEDAY EVEN TAKE US TO THE STARS

A:Benjamen franklin(1706-1790),his kite experiment demonstrate that lighting is electricity,he was the first to use the terms ‘positive and negative charge’,franklin was one of seventeen children.,he quit school at age of ten to become a printer,his life is the classic story of self-made man achieving wealth and fame through determination and intelligency- B:JAME WAATT(1736-1819),was born in scotland .although he conducted no electrical experiment,he must not be overlooked,he was an instrument maker by trade and set up a repair shop in glasgow in 1757.watt through that the stream engine would replace animal power where the number of horses replaced seemed as obvious way to measure the charge for performances.interestingly,watt measured the rate of work exerted by a horse drawing rubbish up an old mine shaft and found it amounted about 22,000ft -ibs per minute.he added a margin of 50% arriving at 33.000 ft-ibs) (C)Willian thomson lord kelvin(1824-1907) was best the know in his invention of a new temperature scale based on the concdpt of absolute zero temperature at -273’c(460’f)to the end of his life,thomson maintained fierce oposition to the idea that energy emitted by radio activity came from within the atom.one of the greatest scientific discoveries of the 19th century.thomson died opposing one of the most vital innovations in the history of sciences
