Proposed a century ago to better explain the mind-bending behavior of the smallest constituents of the universe, quantum theory has implications far beyond the atom. This rich set of laws has applications both practical and extraordinary — from the technology that has revolutionized modern life to the possibility of parallel worlds. Our audience joined Alan Alda as he accompanied Brian Greene, Nobel Laureate William Phillips and other leading thinkers at the vanguard of quantum research on an accessible multimedia exploration of the astounding weirdness of the quantum world. This program is part of the Big Ideas Series, made possible with support from the John Templeton Foundation.
