Genre: Science

We’re surrounded by inventions. Consider the clocks, appliances, and transportation that coordinate our days. Or the televisions, cell phones, and social media that connect us to each other. And the shopping malls, department stores, and catalogs that define the modern retailing experience.
Where did all these inventions come from? How do they work? And how do they reflect—even define—the values of our culture? From prehistoric times to the 21st century, inventions have changed the world, enabling humans to produce more food and energy and to establish social order and cultural meaning. In fact, great inventions have marked a number of key turning points in human history, transforming society and our daily lives. For instance:

The invention of clocks redefined our sense of time, life, and labor.
Telescopes and microscopes led to the scientific method of observation.
Access to clean water has perhaps saved more lives than any other technology in the history of the world.
Coal power gave rise to iron and steel, the basic materials of the Industrial Revolution.
The integrated circuit opened the floodgates for our world of modern electronics.

Now, you can learn the remarkable stories surrounding such monumental inventions—and how consequential these inventions were to history—in Understanding the Inventions That Changed the World. Taught by Professor W. Bernard Carlson of the University of Virginia, who is an expert on the role of innovation in history, these 36 enlightening lectures give you a broad survey of material history, from the ancient pottery wheel to the Internet and social media. Along with recounting the famous inventions you might expect, such as the steam engine, the airplane, and the atomic bomb, this course explores a number of surprising innovations, including beer, pagodas, and the operating room.

You’ll see how each invention is not only a product of engineering know-how, but a result of social and cultural conditions as well. You’ll meet some of the inventors and companies responsible for these innovations, and you’ll investigate what inspired these ideas. You’ll also get an inside look at the sometimes spirited competition between innovators to see who could develop—and market—the best, most cost-effective product.

From ancient China to 21st-century America, from the English coal mines to the high-tech companies of Silicon Valley, this course takes you around the world and across the ages to show you some of the most innovative moments in human civilization. This unique approach to history will boost your technology literacy and give you a completely new appreciation for the everyday objects around you.

Discover the Mechanics of Great Inventions

Material form has shaped the course of human history. In many ways, ours is a story of producing more—more calories, more work, more goods—with the same finite resources. Remarkably, while the materials and production techniques have changed over the centuries, from bronze to semiconductors and from the waterwheel to the assembly line, the process of invention remains largely the same. You’ll discover some key methods that have informed innovation for thousands of years:

Close observation: The great inventors pay attention to details. Close observation allowed ancient metallurgists to develop copper tools and bronze weapons. This same technique allowed 20th-century scientists to develop semiconductors, which are responsible for all of today’s electronics.

Invention by analogy: Inventors often borrow an existing idea and adapt it to another purpose. For instance, ancient potters created coiled pots modeled on the woven baskets already in existence. Similarly, Thomas Edison dreamed up motion pictures as a visual equivalent of the sound recordings played on a phonograph.

Thinking in terms of systems: Inventions don’t exist in a vacuum. Edison’s incandescent light bulb required a network of wires and generators. Likewise, cable television and cellular telephones require networks of computers, cables, satellites, and devices in order to work. Many inventors you study succeeded because they didn't design one machine but an entire system of coordinated devices.

Cultural contact: The story of inventions is the story of cultural contact, from the way merchants developed currencies and alphabets to facilitate trade between different societies, to the 21st-century political revolutions spurred on by social media and the introduction of new ideas into closed societies. You’ll compare and contrast how different cultures approach technical problems, and you’ll see how ideas spread around the globe.

Some of the great innovations you’ll explore are “vernacular inventions,” meaning they are the product of a group or community rather than a single individual. But with modern inventions in particular, we often know the individual responsible. In addition to studying how invention happens, you’ll enjoy learning about the personalities of notable figures such as

Leonardo da Vinci,
Prince Henry the Navigator,
Thomas Edison,
Nikola Tesla,
Alexander Graham Bell,
Henry Ford, and
Grace Hopper.
