Dr. Richard Bulliet, a Professor Emeritus at Columbia University renowned for his work in archaeology, and Dr. Kai James, a computational engineer who employs modeling to validate historical theories, delve into the origins of the wheel. They propose a fascinating idea that prehistoric miners in the Carpathian Mountains engineered the wheel around 6,000 years ago. The discussion covers the wheel's impact on mining and transport, the cultural shifts during the Copper to Bronze Age, and the intricate relationship between early technology and environmental factors.
