The idea of mimicking nature in manmade inventions is not new by any means. The Greeks applied “the golden ratio”, also called the golden mean or golden selection, to their art and architecture. The Pantheon is based on the golden ratio. Even the volutes on ionic columns use these proportions. Medieval alchemists would initially determine a plant’s potential healing qualities by what it looked like. For example, the leaves of the lungwort plant, which resemble the human lung, were used to treat respiratory problems.
