Roger Joseph Boscovich (see names in other languages; 18 May 1711 – 13 February 1787) was a physicist, astronomer, mathematician, philosopher, diplomat, poet, and Jesuit from Ragusa (today Dubrovnik, in Croatia) who lived for a time in France, England and some Italian states [1]. He is famous for his atomic theory, given as a clear, precisely-formulated system utilizing principles of Newtonian mechanics. This work inspired Michael Faraday to develop field theory for electromagnetic interaction, and was even a basis for Albert Einstein's attempts for a unified field theory, according to Einstein's coworker Lancelot Law Whyte.[2] Also according to John D. Barrow, Professor at Cambridge University and a Fellow of the Royal Society: Boscovich was the first to envisage, seek, and propose a mathematical theory of all the forces of Nature; the first scientific theory of everything. [3] Boscovich also gave many important contributions to astronomy, including the first geometric procedure for determining the equator of a rotating planet from three observations of a surface feature and for computing the orbit of a planet from three observations of its position. In 1753 he also discovered the absence of atmosphere on the Moon.[4] The lunar crater Boscovich is named after him.
