Signal-to-noise ratio is the relationship between meaningful information (a signal) and external factors (background noise). In a broader theoretical sense, it can refer to seeking out meaning from complexity. We do this in our daily lives, constantly and without thought, each time we take mundane actions and, ultimately, whenever we attempt to make sense of the world we live in. The young Scottish artist Katie Paterson toys with this balance. Whether it’s hacking a mobile phone and burying it deep in the Arctic to capture the dying murmurs of a melting iceberg, or working with astronomers to capture the earliest known light of the universe, Paterson’s work—with a nod to scientific research—explores the curiosities within some of our universe’s infinite blips: remote ones, old ones, ones long gone.
