Feb 9th is National Pizza Day in the USA! This is a good time to learn about the "pizza effect." It helps explain why assumptions about the history and development of certain cultural practices and traditions help build hardy historical myths. Learn about the "pizza renaissance" in Italy, the "Hindu renaissance across India, the "Cornish pasty renaissance" in south-west England, and the "Clancy Brothers" or "traditional music renaissance" in Ireland! Listen while enjoying your favorite pizza pie!
