page coverage in the New York Times.[36] It took many years for British sea captains to adopt Franklin's advice on navigating the current; once they did, they were able to trim two weeks from their sailing time.[37][38] In xxxx, the oceanographer and cartographer Matthew Fontaine Maury noted that Franklin only charted and codified the Gulf Stream, he did not discover it: Though it was Dr. Franklin and Captain Tim Folger, who first turned the Gulf Stream to nautical account, the discovery that there was a Gulf Stream cannot be said to belong to either of them, for its existence was known to Peter Martyr d'Anghiera, and to Sir Humphrey Gilbert, in the 16th century.[39] Electricity His discoveries resulted from his investigations of electricity. Franklin proposed that "vitreous" and "resinous" electricity were not different types of "electrical fluid" (as electricity was called then), but the same electrical fluid under different pressures. He was the first to label them as positive and negative respectively,[40] and he was the first to discover the principle of conservation of charge.[41] In xxxx he published a proposal for an experiment to prove that lightning is electricity by flying a kite in a storm that appeared capable of becoming a lightning storm. On May 10, xxxx Thomas-François Dalibard of France conducted Franklin's experiment using a 40-foot (12 m)-tall iron rod instead of a kite, and he extracted electrical sparks from a cloud. On June 15 Franklin
may possibly have conducted his famous kite experiment in Philadelphia, successfully extracting sparks from a cloud. Franklin's experiment was not written up with credit[42] until Joseph Priestley's xxxx History and Present Status of Electricity; the evidence shows that Franklin was insulated (not in a conducting path, where he would have been in danger of electrocution). Others, such as Prof. Georg Wilhelm Richmann were indeed electrocuted during the months following Franklin's experiment. In his writings, Franklin indicates that he was aware of the dangers and offered alternative ways to demonstrate that lightning was electrical, as shown by his use of the concept of electrical ground. If Franklin did perform this experiment, he may not have done it in the way that is often described, flying the kite and waiting to be struck by lightning, as it could have been dangerous.[43] Instead he used the kite to collect some electric charge from a storm cloud, which implied that lightning was electrical.[citation needed] On October 19 in a letter to England explaining directions for repeating the experiment, Franklin wrote: When rain has wet the kite twine so that it can conduct the electric fire freely, you will find it streams out plentifully from the key at the approach of your knuckle, and with this key a phial, or Leiden jar, may be charged: and from electric fire thus obtained spirits may be kindled, and all other electric experiments [may be] performed which
are usually done by the help of a rubber glass globe or tube; and therefore the sameness of the electrical matter with that of lightening completely demonstrated.[44] Franklin's electrical experiments led to his invention of the lightning rod. He noted that conductors with a sharp rather than a smooth point were capable of discharging silently, and at a far greater distance. He surmised that this knowledge could be of use in protecting buildings from lightning by attaching "upright Rods of Iron, made sharp as a Needle and gilt to prevent Rusting, and from the Foot of those Rods a Wire down the outside of the Building into the Ground;...Would not these pointed Rods probably draw the Electrical Fire silently out of a Cloud before it came nigh enough to strike, and thereby secure us from that most sudden and terrible Mischief!" Following a series of experiments on Franklin's own house, lightning rods were installed on the Academy of Philadelphia (later the University of Pennsylvania) and the Pennsylvania State House (later Independence Hall) in xxxx.[45] In recognition of his work with electricity, Franklin received the Royal Society's Copley Medal in xxxx and in xxxx he became one of the few 18th century Americans to be elected as a Fellow of the Society. The cgs unit of electric charge has been named after him: one franklin (Fr) is equal to one statcoulomb. Wave theory of light Franklin was, along with his contemporary Leonhard Euler, the only major scienti
