Researcher David Politzer, a professor from Caltech, just won the 2004 Nobel Prize in physics. Politzer and two other American scientists studied a phenomenon called the “strong force,” an energy that holds the nuclei of atoms together. The “strong force” holds quarks together to form protons and neutrons, two of the basic elements of atoms. Dr. David Baltimore, biologist, Nobel Laureate, and President of Caltech, and Professor Mark Wise, McCone Professor of High Energy Physics at Caltech, join Host Larry Mantle to talk about the Nobel Prize awarded to their colleague, David Politzer.
