Dialectics of Nature  is an unfinished 1883 work by Friedrich Engels that applies Marxist ideas – particularly those of dialectical materialism – to nature. Engels wrote most of the manuscript between 1872 and 1882, which was a melange of German, French and English notations on the contemporary development of science and technology; however, it was not published within his lifetime. In later times, Eduard Bernstein passed the manuscripts to Albert Einstein, who thought the science confused (particularly the mathematics and physics) but the overall work worthy of a broader readership. After that in 1925, the Marx–Engels–Lenin Institute in Moscow published the manuscripts(a bilingual German/Russian edition).
