Wgtd's The Morning Show With Greg Berg

The recent thefts at The Louvre in Paris brought to mind a past Morning Show conversation about Leonardo da Vinci and his most famous painting, the Mona Lisa, which is displayed at the Louvre. Bulent Atalay is the author of "Math and the Mona Lisa: The Art and Science of Leonardo da Vinci." This interview was recorded and initially broadcast in 2014.
