Back in Russia, Kozlovsky became part of the literary circles including Vasily Zhukovsky, Pyotr Vyazemsky, and Alexander Pushkin. In 1836 and 1837, he contributed three popular scientific articles to Pushkin's journal "Современник" (The Contemporary). The first, in part 1, was "Разборъ парижского математическаго ежегодника на 1836 годъ", a review of the "Annuaire du Bureau des Longitudes" for 1836 edited by François Arago; the second, in part 3, was "О надежде" (On Hope), an article on probability theory; the third, in part 6, was "Краткое начертание теории паровых машин", (A short outline of the theory of steam engines), which was illustrated.
