This episode explores the invention of the wheel, a deceptively simple creation that revolutionized transportation, machinery, and human civilization. First appearing around 3500 BCE as a potter’s tool, the wheel evolved into a cornerstone of mobility, enabling carts, chariots, and expanded trade networks. It later powered mills, engines, and modern infrastructure—driving industrial growth and technological advancement.

More than just a physical tool, the wheel became a symbol of progress, cycles, and transformation. From ancient warfare to space exploration, its rotating motion has moved not just people and machines, but entire societies forward.
