The medal
In 1985, the 100th anniversary of the birth of Niels Bohr, UNESCO minted a gold medal to commemorate the father of quantum physics and one of the most eminent scientists of the 20th century. Sculpted by Siv Holme-Muse of Sweden, the medal bears the profile of Bohr while the rear depicts his drawing of electrons orbiting around an atomic structure, his formula ''E2-E1=hy2'' representing electrons in relation to hydrogen, and his signature. It also bears the inscription: ''Contraria sunt complementa'' (Opposites are complementary), Bohr's Complementarity (physics), principle of complementarity.2013 awards
