Artificial intelligence (AI)(人工智能) is the ability of a computer program or a machine to think and learn. It is also a field of study that tries to make a computer “smart”. John McCarthy, a scientist, came up with the name “artificial intelligence” in 1955. Many things such as learning and problem solving can be done by computers, though not in the same way as we do.

An unusual goal of AI research is to create computer programs that can learn, solve problems, and think logically(逻辑地). At present we use the term AI for successfully understanding human speech, recognizing(识别) human faces, operating self-driving cars and competing in some game systems like Chess and AlphaGo(阿尔法狗). Some people also consider AI a danger to humans if it develops too quickly. Professor Stephen Hawking(霍金), a well-known British scientist, was not for this kind of technology.

Math is the basic language of AI. If we raise the standard in the learning of math, our students will be more likely to become successful AI designers in the future. We not only want bright students, but also need to attract average students and give them the math skills which are needed to change them into AI designers. Besides, a good knowledge of computer science is also necessary for AI designing.

Scientists hope to create creative and emotional AI which can possibly understand human feelings or create art. Many ways and tools have been tried to discover this fascinating field.
