In the last 50 years, the personal computer, the internet, and the smartphone have changed the way we live. 00:00:15
But which other inventions and discoveries have transformed our lives? 00:00:27
Let's take a trip back in time. 00:00:33
By about 300,000 years ago, our ancestors had discovered fire. 00:00:37
This meant they could keep warm and cook food. 00:00:45
The invention of the wheel in 3500 BC made things easier to transport. 00:00:49
In 2000 BC, the compass appeared in China. 00:00:58
It helped people navigate without using landmarks. 00:01:02
About 2000 years ago, also in China, paper was developed. 00:01:08
Although first used for wrapping things, people eventually started writing on it. 00:01:14
Johannes Gutenberg's invention of the printing press in 15th century Germany meant that people were able to print hundreds of copies of a page quickly. 00:01:23
This led to the rise of science, filled our homes with books and gave us the newspaper. 00:01:38
The late 19th century was a time of great change. 00:01:49
The light bulb was invented. 00:01:54
As was the car. 00:01:57
The 20th century began with the creation of the airplane. 00:02:00
The same century also gave us the radio and the television. 00:02:08
By the end of the 1960s, we had even sent men to the moon. 00:02:15
The smartphones we use today are more powerful than the computers 00:02:23
which sent Neil Armstrong and Buzz Aldrin to the moon. 00:02:27
Technology is changing fast. 00:02:33
What will the next invention be? 00:02:36
