A few thousand years ago, people started to use wheels on carriages. In the early 19th century, the first trains began to carry passengers. At the start of the 20th century, cars became popular. Without the wheel, we would not have these inventions. Great inventions Great inventions change the world. They help people live a better life.

Since then, people have been able to speak to each other over long distances. Today millions of people across the world own mobile phones. They allow people to keep in touch with each other anytime, anywhere. The light bulb Thomas Edison developed the first practical light bulb in 1879.
