Atomium

Geschiedenis

The Atomium is a building in Brussels originally constructed for Expo 58, the 1958 Brussels World's Fair. Designed by the engineer André Waterkeyn and architects André and Jean Polak, it stands 102m tall. Its nine 18m diameter stainless steel clad spheres are connected so that the whole forms the shape of a unit cell of an iron crystal magnified 165 billion times. It is now a museum.Tubes of 3m diameter connect the spheres along the 12 edges of the cube and all eight vertices to the centre. They enclose stairs, escalators and a lift (in the central, vertical tube) to allow access to the five habitable spheres which contain exhibit halls and other public spaces. The top sphere includes a restaurant which has a panoramic view of Brussels. In 2013 CNN named it Europe's most bizarre building.SubjectIn the 1950s, faith in scientific progress was great, and a structure depicting atoms was chosen to embody this. The Atomium depicts nine iron atoms in the shape of the body-centred cubic unit cell of an iron crystal, magnified 165 billion times.Though the Atomium depicts an iron unit cell, the balls were originally clad with aluminium. Following the 2004–2007 renovations, however, the aluminium was replaced with stainless steel, which is primarily iron. Likewise, while the subject of Atomium was chosen to depict the enthusiasm of the Atomic Age, iron is not and cannot be used as fuel in nuclear reactions.
