Big data (数据) is a lot of sets of information that are put together so they can be used by a computer program. The computer program looks for different kinds of answers or patterns in the data. Big data can have different kinds of information from many sources, such as information that comes from schools, social media sites, companies and governments. One set of data can have people’s names and addresses. Another set can have what they like, where they go to school, and how much time they spend on the computer.

Big data can be used in many ways. The government uses it to understand how many people travel on buses or trains. This information is then used to make bus or train systems better. Some schools use big data to understand which children may need extra help in class. The teacher can then give certain students more help or support so those students can succeed in school. Companies use big data, too. It helps them understand who buys their products. For example, one company uses weather data to see when people eat the most ice cream.

Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is born too early will get sick. The hospital can then take extra steps to take care of that baby so he or she does not get sick. Big data can also be used for bad reasons. It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong.

How can big data be used for good and bad thing? It is because the computer programs are written by people. People think in a certain way, and they build a model of those ideas.

Sometimes we forget that many things we use every day were not always there. They had to be i1.. Someone had to have an idea. Then they had to do a lot of experiments with the idea until it worked well. Here are few you might like to read about:

In Maine, the northeast of the U. S., winters are long, windy and cold. Every winter, Chester Greenwood's ears got so cold that they turned colors. When he was 15, Chester got ice skates for his birthday. He wanted to go skating. The cold wind and his frozen ears soon sent him running home. The next day, Chester tied a scarf around his ears. It was w2., but too uncomfortable. Then he got a GREAT IDEA.

Chester made two oval loops out of wire. He asked his grandmother to sew covers on the ovals Then she connected the ovals with another wire. The ovals fit over his ears. Chester had invented earmuffs! They saved his ears and made him rich. People in Maine found another way to r3. Chester. December 21th, the first of winter, is Chester Greenwood Day.

Sometimes inventions happen by chance. As a boy. Thomas Alva Edison was called Al. When he was 12 years old, he got his first j4.. He sold newspapers and candies on the train. One day on the job, he bravely s5. a boy from being run over by a train. The boy's father worked a telegraph. Al asked how to run a telegraph. Not only did Al learn the telegraph, but he made a better one. It was one of his earliest GREAT IDEAS

Edison's new telegraph made a lot of money. Later，he became the first person to o6.and run an invention business. He was good at that，too. We could thank Thomas Edison every day. He had many，many GREAT IDEAS such as bulbs，movie cameras，and batteries. Edison is the one who invented more things than a7.else in the world.

So，who knows？You might invent something some day！
