• When you imagine inventors, you probably picture a lone genius in a laboratory concocting brilliant devices, experimenting and redesigning until some concept or contraption works perfectly. At that point, the new invention is unveiled to the world, a stunning piece of new technology that instantly changes everything.
• Well, you've got part of it right. There's certainly a lot of redesigning and experimenting when it comes to inventions, but it takes a lot longer than you think. It also takes far more people than that lone genius.
• As you'll see when you read about these 10 world-changing inventions, no invention is created in a vacuum. Every single one was built on previous inventions created by other inventors years, decades or even centuries before. Every invention has problems, and it might not be until some other inventor comes along that they get solved. To confuse things further, it usually isn't the original inventor who gets all the credit, but rather the inventor who made the one crucial improvement that makes us all want one.

The plough/plow:

• Compared to some of the gleaming, electronic inventions that fill our lives today, the plow doesn't seem very exciting. It's a simple cutting tool used to carve a furrow into the soil, churning it up to expose nutrients and prepare it for planting. Yet the plow is probably the one invention that made all others possible.
• No one knows who invented the plow, or exactly when it came to be. It probably developed independently in a number of regions, and there is evidence of its use in prehistoric eras. Prior to the plow, humans were subsistence farmers or hunter/gatherers. Their lives were devoted solely to finding enough food to survive from one season to the next. Growing food added some stability to life, but doing it by hand was labor intensive and took a long time. The plow changed all that.
• Plows made the work easier and faster. Improvements in the plow's design made farming so efficient that people could harvest far more food than they needed to survive. They could trade the surplus for goods or services. And if you could get food by trading, then you could devote your day-to-day existence to something other than growing food, such as producing the goods and services that were suddenly in demand.
• The ability to trade and store materials drove the invention of written language, number systems, fortifications and militaries. As populations gathered to engage in these activities, cities grew. It's not a stretch to say that the plow is responsible for the creation of human civilization.
