UNESCO Niels Bohr Medal

The UNESCO Niels Bohr Medal was first minted in 1985 to commemorate the 100th anniversary of the birth of the Danish nuclear physicist Niels Bohr. It is awarded by UNESCO to recognise those who have made outstanding contributions to physics through research that has or could have a significant influence on the world.

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 principle of complementarity.
