context_page_description: Franz Ulrich Theodor Aepinus was a German and Russian Empire natural philosopher. Aepinus is best known for his researches, theoretical and experimental, in electricity and magnetism.
context_section_description: His principal work, Tentamen Theoriae Electricitatis et Magnetismi (An Attempt at a Theory of Electricity and Magnetism), published at St Petersburg in 1759, was the first systematic attempt to apply mathematical reasoning to these subjects. 
  He also published a treatise, in 1761, De Distributione Caloris per Tellurem (On the Distribution of Heat in the Earth), and he was the author of memoirs on different subjects in astronomy, mechanics, optics and pure mathematics, contained in the journals of the learned societies of St Petersburg and Berlin. His discussion of the effects of parallax in the transit of a planet over the sun's disc excited great interest, having appeared (in 1764) between the dates of the two transits of Venus that took place in the 18th century.
