  1. Specifically this section:

    > When Ohm first published his work, this was not the case; critics reacted to his treatment of the subject with hostility. They called his work a “web of naked fancies”[11] and the Minister of Education proclaimed that “a professor who preached such heresies was unworthy to teach science.”[12] The prevailing scientific philosophy in Germany at the time asserted that experiments need not be performed to develop an understanding of nature because nature is so well ordered, and that scientific truths may be deduced through reasoning alone.[13] Also, Ohm’s brother Martin, a mathematician, was battling the German educational system. These factors hindered the acceptance of Ohm’s work, and his work did not become widely accepted until the 1840s. However, Ohm received recognition for his contributions to science well before he died.

    > In the 1850s, Ohm’s law was widely known and considered proved. Alternatives such as “Barlow’s law”, were discredited, in terms of real applications to telegraph system design, as discussed by Samuel F. B. Morse in 1855.[14]
