Lynn and John’s first guest is Dr. Andrew Newberg, co-author of How Enlightenment Changes Your Brain: The New Science of Transformation. In this original and groundbreaking book, Andrew Newberg, M.D., and Mark Robert Waldman turn their attention to the pinnacle of the human experience: enlightenment.

In segment two, Pagan Kennedy, author of Inventology: How We Dream Up Things That Change the World tells how a father cleans up after his toddler and imagines a cup that won't spill. An engineer watches people using walkie-talkies and has an idea. A doctor figures out how to deliver patients to the operating room before they die. By studying inventions like these — the sippy cup, the cell phone, and an ingenious hospital bed — we can learn how people imagine their way around "impossible" problems to discover groundbreaking answers.
