"Robert F. Young - The Second Philadelphia Experiment" - читать интересную книгу автора (Young Robert F) In our own story, KING'S EVIL (F&SF, Oct. 1956), mention was made of of the first
"Philadelphia experiment"—of which every school-child knows—kites, keys, thunder and lightning. Up till now, however, that this experiment had not been the last, efcap'd the publick Knowledge. We will say no more, but allow the reader to read on . . . perhaps rueful and regretful that the subject of the knowledge was ever discovered at all. The Second Philadelphia Experiment Robert F. Young (NOTE: WITH THE EXCEPTION of the opening paragraph, which is included to indicate the probable chronological point in the Autobiography at which the pages dealing with the second Philadelphia experiment originally occurred, the following document has never before been published. Why, after removing the pages from the rest of, his manuscript, Dr. Franklin did not burn them in keeping with his intention, is anybody's guess, and how they could have gone undiscovered for so many years is a mystery which will probably never be resolved. In any event, the account of the second Philadelphia experiment has finally come to light, happily providing us with an instance of the Greco-Overby Audio-Temporal Throwback Principle in action—an instance that predates the discovery of the principle by over three hundred years.) What gave my book * (* A pamphlet on the sameness of lightning and electricity, published in England circa 1752.) the more sudden and general celebrity was the success of one of its proposed experiments, made by Messrs. Dalibard and De Lor at Marly, for drawing lightning from the clouds. This engag'd the public attention every where. M. de Lor, who had an apparatus for experimental philosophy, and lectur'd in that branch of science, undertook to repeat what he called the Philadelphia Experiments; and, after they were performed before the king and court, all the curious of Paris flocked to see them. I receiv'd in the success of a similar one I made soon after with a kite at Philadelphia, as both are to be found in the histories of electricity. I would like, however, to make some mention of a second experiment which I conduct'd not long after that time in the privacy of my home and which result'd in a most singular phenomenon. In anticipation of the noble uses to which electricity will some day be put, I had for some time been seeking to improve upon the Leyden jar in the hope of applying my discovery toward some practical purpose, and to this end I had devis'd a sort of super-jar from a large and thick-walled demijohn, which I had previously stripp'd of its wicker casing. The intervening years have dimm'd my memory insofar as the exact arrangement of the apparatus which I then assembl'd is concern'd, but I do recall that in addition to the Leyden jar it consist'd among other things of a glass lamp chimney, a quartz paperweight, a brass doorkey, a kite, a tuning fork, an iron wille, and two pewter plates. I had sent the kite and key aloft earlier in the evening, having first ascertain'd that there was a good likelihood of a thunderstorm, and I purpos'd to convert the electrical fluid which would drench the immediate area once the key procur'd lightning from the clouds, into light. The apparatus assembl'd to my satisfaction, I sat down before my work table to wait. Distant rumblings of thunder sound'd, and occasionally the darkness beyond the windows leap'd into brief and blinding brightness. Not wishing to jeopardize the safety of any of the members of my family, I had arrang'd matters so that none of them would be present during the experiment, and hence I had the entire house to myself. The rumbling grew in volume, and the brightnesses increas'd both in frequency and in intensity. I had to proceed on the assumption that the kite was still aloft, since were I to leave the apparatus the moment for which I eagerly wait'd might come and go during my absence, leaving me no more enlighten'd than I had been before. The thought that I might be playing with forces the true nature of which I could not even guess at cross'd my mind, but I did not let it dissuade me from my purpose, having come to the |
