Introduction to 10 Inventions That Changed the World
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.
