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 [[Saint Petersburg|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.<ref name="EB1911" />
