Like other watershed figures, Kant has contributed to the shape of world civilization, and the conceptualization we have of the world today. His practical ideas, such as the Categorical Imperative and its implications (1785), informed the Universal Declaration of Human Rights (1948), the Political and Economic Covenants (1966), and the International Criminal Court (2002). His exploration of natural sciences and his metaphysical ideas, particularly those of his pre-critical period (1747–1770), are stunning. Kant gave the first account of the evolutionary reciprocity of spacetime and momentum-energy, and formulated the first general law of free field radiation (1747). He suggested the conceptual solution of the three body problem, which emerges in the interplay of Earth, Moon, and Sun (1754). He was the first to construct a detailed evolutionary cosmology (1755). His ideas on biospherical dynamics allowed him to predict the rhythms of the monsoon and the oscillation of coastal winds (1755–1757). He suggested that the building blocks of matter are energy bubbles (1756)—an idea that is useful today in superstring theory in the guise of Calabi-Yau manifolds.
