AMSE Science Report with guest Keith Houston

Keith Houston, author of the book, Empire of the Sum: The Rise and Reign of the Pocket Calculator joined us to recently to speak on our podcast AMSEcast. We talked about counting and ciphering from the earliest days of humanity up to the momentous creation of those wonderful pocket devices in the 1970's. One of the historic models we spoke about was the TI 81 that became a worldwide sensation for Texas Instruments.
