See how a little part of everywhere in the world is inside your phone. Meet Dr. Joshua A. Bell, cultural anthropologist at the National Museum of Natural History. Joshua studies the natural history of cellphones, cradle to grave. Take a journey with him along a supply chain from the mines that produce cellphone minerals to the millions of discarded cellphones. Consider how cellphones have revolutionized our communications and changed our personal interactions. Reflect with Joshua about the implications of a cellphone being one of our most intimate possessions.
