A new exhibit at the Smithsonian's National Museum of Natural History charts how cellphones have changed our lives and our planet. The exhibit, "Cellphone: Unseen Connections," builds on a longstanding partnership between Smithsonian and GW. In addition to GW and Smithsonian scholars, as many as 100 students—GW undergraduate, graduate and Ph.D. students, as well as D.C. area high school students—contributed to the research.
