Marx and Engels closely followed the development of the natural sciences throughout their lives, philosophically generalizing their achievements and shedding light on them from the perspective of dialectical materialism.

The problems of theoretical natural sciences occupy a prominent place in one of the most important works of Marxist literature, in Engels' Anti-Dühring, where there is a developed exposition of the constituent elements of Marxist theory.

Numerous observations regarding problems of the natural sciences are found in a series of other works by Marx and Engels, as well as in Marx's foundational work, Capital.

The correspondence between Marx and Engels gives great importance to the problems of the natural sciences. However, Engels provided the most developed exposition, encompassing all the main branches of the natural sciences and mathematics in his work Dialectics of Nature, which he worked on in close collaboration with Marx and which, although unfinished, is magnificent for its richness of thought.
