This chart was published in 1976 so it’s obviously outdated and some of the proportions are way off. For example, Astatine (At) looks rather large despite the fact that is one of the rarest elements on Earth, with a total existing amount of less than one gram at any given time. Francium (Fr) is also extremely rare - there is at most one ounce in the Earth’s crust at any time - and yet it looks larger than Neodymium (Nd) which, although it belongs to the rare-earth metals, is not rare at all. Its abundance in the Earth’s crust is about 38 mg/kg, which is the second highest among rare-earth elements, following cerium.
made from 3D printed pieces, ‘the wheel of life’ by czechdesigner monika horcicova is a skeletal sculpture that is based on a symbol of infinity. the round structure refers to the repeated cycle of conception and death, with walking legs used to evoke the image of people in motion. the idea explores the fragility of human bones, which despite this are able to carry the weight of the whole human figure during its life. the plaster composite pieces were 3D printed and then placed in a form and casted in a polyurethane resin, the individual pieces were then assembled into a single object.
