Keith & Russ talk with Shiv Khanna, professor of physics, Virginia Commonwealth University. Khanna talks about why reducing matter to a very small scale dramatically changes their properties, and offers the example of gold and aluminum and how they change when they are broken down into very small particles. Khanna also explains the concept of "superatoms" and how these superatoms can expand the periodic table into 3 dimensions. http://www.people.vcu.edu/~khanna/ Aired May 19, 2013.
