About the coin

The design displays parts of the equation that Josip Plemelj solved as a first person in the world. Numbers and symbols rotate on circumferences that depict planet rotation, movement in space, as well as composing individual unsolvable elements into whole. That way the design shows both fields of Josip Plemelj's work, i.e. mathematics and astronomy. The inscription ‘JOSIP PLEMELJ 1873’, the name of the issuing country ‘SLOVENIJA’ and the year of issuance ‘2023’ are integrated in the design. The coin’s outer ring bears the 12 stars of the European flag.
