19、mart, Tesla had been very sick in the 1870s before he moved to the U.S. His doctors thought he might not survive. Since there was relatively little else he could do during that period of time, he read all the books he could at the local library. Among those books were several of Mark Twains earlier

20、works, which Tesla described as “so interesting as to make me completely forget my hopeless state”. He went on to say that those books may have been the reason for his recovery (恢复).The Irish Times reports that the writer and the inventor became friends in the 1890s.
