Array of Things began as a failed workshop for high school students. Three years ago, Charlie Catlett, director of the Computation Institute’s Urban Center for Computation and Data and senior computer scientist at Argonne National Laboratory, and fellow researchers were helping students assemble simple air quality monitors with the intent to deploy them in downtown Chicago to teach about collecting data in a major city. (The Computation Institute is a joint initiative between the University of Chicago and Argonne.)
