Science is search for the profound knowledge. Scientists investigate the world around us. They observe how things work and develop ideas about ways to make them work better. Sometimes they try to test an idea to explain how something works. Scientists perform experiments to find out how things work. The knowledge that they discover is useful for many things. It can help to build new machines. It can help scientists to develop new medicines or cure a disease. Technology is the use of scientific knowledge to create new things.
Then what is an Inventor?
An inventor is a person who creates a new idea or device to perform a task. An invention is the new technology created. An inventor with a new idea or design for an invention may decide to have the idea protected. The idea gets protection from the law in a paper called a patent. A patent prevents other people from making, using, or selling the new idea without permission from the inventor. Some inventions are simply a better way of doing or building something. They may improve an existing technology. Other inventions are much more complicated.
Today's technology has been in the process of development for thousands of years. New inventions are constantly changing how people work and play. They change how people think and live. The future constantly brings us even more changes. This will happen as we continue to learn about the world.
Do we depend on science and technology?
What did you do today? Did you talk on the telephone? Did you ride in a car or on a bus? Did you use a computer or turn on a light? If you did any of these things, you used technology.
Almost everybody uses some form of technology at work, home, or school. Computer programmers use computer technology to write a computer program. People may write letters using a computer program called a word processor. Many people work in the entertainment industry. Camera operators use television and motion-picture cameras. They use them to make TV shows and movies. Disc jockeys, or DJs, play records and CDs on the radio.
