[music playing] [motor revving]

JASON SILVA: What does it take to power a global civilization to connect billions of people across continents? It takes the power of transportation. From the beginning, speed and strength were paramount in the hunt, on the battlefield, for holding together far-flung empires. We sought new forms of power, harnessing the forces of nature to drive us forward—the horse, the wheel, steam power, jet engine. Every new innovation powered our next great leap.

Transportation has become our exoskeleton allowing us to transcend our biology. [music playing] Faster than sound, farther than the moon, our inventions give us a level of power we never imagined. With our machines we carved through solid rock, tunneled beneath the sea floor, connecting the world, mixing distant cultures. Freedom of movement has given us freedom of mind.

The flow of people and materials exposes us to new ideas and new understanding. This is the story of how transportation turned society inside out, how engines and animals powered the rise of civilization, and how the innovations that drive humanity forward made us modern. This is "Origins."
