Understanding the Inventions That Changed the World

We're surrounded by great inventions that have transformed our daily lives, from the steam engine to the Internet. Begin your exploration of great inventions by considering just how pervasive inventions truly are. Do we notice them in the world around us? Do we know how they work? Who invented them, and why?

Step back to the Stone Age and look at the craft of pottery and the development of metals. Although we might think of ancient people as "primitive," early humans were remarkably observant about the world around them, which led to several complex inventions.

One of the recurring themes in the history of invention is the way technology leads to material abundance. See how the Agricultural Revolution changed life for early humans. Then trace the development of alcoholic beverages from the earliest days of civilization through the Middle Ages and consider the cultural insights alcohol can offer.

In addition to creating material abundance, technology, whether it's an oxcart or a telecommunications network, facilitates interaction between people. Explore the role of trade in early societies and how ships, coins, and the alphabet shaped the civilizations of the ancient Mediterranean.

To study the way people have used technology to secure and maintain political power, journey east to China and examine the role of the crossbow in the Warring States Era. As the world's first machine with interchangeable parts, the crossbow is a marvel of engineering that shaped the political history of China for centuries.

We're all familiar with the glory of Roman engineering, from the Romans' system of roads to their impressive monuments. How did these structures work from a technical standpoint? And why build them? Delve into Roman history and explore the way in which technology served state ends.
