later, in 1955, Jean Meffroy restarted Haret’s research using new techniques. Soon after his return to Romania, Haret abandoned research, focusing for the rest of his life on teaching and, as Minister of Education, on the reform of the education system. He only published an article on the secular acceleration of the Moon in 1880 and one on Jupiter’s Great Red Spot (1912). In 1910 he published Social mechanics, which used mathematics to explain social behaviour (somehow anticipating the fictional "psychohistory" branch of mathematics developed by Hari Seldon, the fictional character of Isaac Asimov's Foundation, published 40 years later).
