About This Episode
This is an extended audio interview from “The Salt of the Earth” on StarTalk Radio with Neil deGrasse Tyson.
Scientifically speaking, table salt is simply sodium + chloride. But historically, salt has had a major impact on human culture and society. Neil interviews Mark Kurlansky, author of Salt: A World History, to find out how the marriage of these two elements on the periodic table have periodically seasoned the flow of human events.
Please note that this is the raw interview, with minor edits made to the original interview by our producer to address recording issues, not content. Enjoy!
