It was printed in four editions in various years. The book made Franklin famous worldwide. == Background == Franklin was first attracted to the study of electricity when he saw showman Archibald Spencer do magic demonstrations in Boston in 1743 and in Philadelphia in 1744. He purchased Spencer's equipment for his electricity experiments. Franklin then began turning over his printing business affairs in 1746 to his business partner David Hall. He was forty years old and went into semi-retirement so he could do research on electricity. Peter Collinson in 1746 donated to the Library Company of Philadelphia (founded by Franklin) a Leyden jar battery and an account of the new German experiments in electricity. Collinson was a wealthy Quaker cloth merchant, a Fellow of the Royal Society and one of the founders of the Society of Antiquaries of London. Franklin made use of the unique battery and other associated equipment that was additionally provided by Thomas Penn, son of William Penn. He worked with a team on this electrical research who were Ebenezer Kinnersley, Thomas Hopkinson, and Philip Syng. This was the first scientific research laboratory in America. Franklin did his experimentation with static electricity in the middle of 1747 and referred to it as "these new wonders." He considered his findings as non-speculative and something anyone could repeat or prove if they wished. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Experiments and Observations on Electricity」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
