Megastructures
From the Great Pyramid at Giza to the towering skyscrapers of today, humans have engineered massive constructions for at least 5,000 years. But why? How do biology and human emotions affect our desire to build gigantic structures? Why were the earliest mega-structures almost always pyramids? Why do people have the urge to build tall, and how do mega-structures on earth echo a basic principle embedded in the very structure of the universe?

World of Weapons
Humans have small teeth and no claws or armor, so how do we project our power? Warfare has defined traditional history, but Big History digs deeper to reveal how it all began. We see how bat poop and ancient trees shaped the history of weapons, and link the gun all the way back to a change in our bodies that turned us into throwing machines.

They form natural boundaries, dictate how we spread around the planet, create natural defenses, and control our weather. From the World War that began with a gunshot in the Balkans to the feuds of the Appalachians, mountains have also been flashpoints for violence. They provide minerals and metals that make civilization possible, and the water that feeds billions, yet we were never designed to live in their extreme environments. Without mountains earth would be desolate and uninhabitable, and scientists now believe that an invisible mountain range made life possible ...

Secret codes run the world. The code of life, DNA, is the operating system for all organisms, which spawned intelligent life like us who eventually created codes of our own--language that allows us to talk and the alphabet that lets us write. We've even created an entire digital universe built of binary code that powers the machinery of the modern age. But is it possible that the universe itself runs on code?
