Commissioned by the University of Edinburgh’s College of Science and Engineering to celebrate King’s Building’s centenary, Scottish artist and alumna Katie Paterson’s Ideas open to the public. 100 three-line texts, each a thought experiment rendered in stainless steel, are planted throughout the campus, inviting a cosmic treasure hunt. “The artwork has never been created as an outdoor experience, with such immensity,” states Paterson. “There couldn’t be a more apt context.”
