  • Excellent podcast!

    This podcast reviews the latest developments in theoretical physics. As a former physicist, this series is great for me. It enables me to keep in touch with the latest ideas from the field I still love. The hosts do a brilliant job talking through ideas, and the topics teachers are always interesting. more
