The medal is made by Danish sculptor Rikke Raben for the Niels Bohr Institute. On the front is a portrait of Niels Bohr, the atom sign and stars. The illustration on the back is inspired by a quote from Bohr: What is it that we human beings ultimately depend on? We depend on our words. We are suspended in language. Our task is to communicate experience and ideas to others. On the back of the medal: Unity of Knowledge – the title of a lecture given by Bohr at Columbia University in 1954. Nosce te ipsum is Latin and means "know thyself". This quote originates from the Oracle of Delphi, in the Temple of Apollo in Greece.
