Happy holidays to all our listeners!

Thanks to J. J. Thomson‘s plum pudding model of the atom, chemistry will be forever associated with 19th-century British Christmas traditions. His model was soon discarded, but it remains a staple of high school chemistry textbooks. On today’s episode, we introduce a new segment, “Tools of the Trade,” that looks at the  models, instruments, and artifacts—whether still in use or long discarded—that help scientists do their jobs. We also visit with Emilio Mignucci, one of the owners of Philadelphia’s famous DiBruno Brothers gourmet foods shop, to find out the story behind ham, that favorite holiday food. Element of the Week: Tin.
