Artificial intelligence is a branch of computer science, not a single discipline, image recognition, natural language processing, robotics, language recognition, expert system and so on, each research is full of challenges. Interested in artificial intelligence, but unable to determine the specific direction, how to understand the status and research areas of artificial intelligence
the author recommends four undergraate general books. For most people, the reading difficulty is not high, the formula and theory are few, the content is interesting, and they can read on; The information is fresh and complete. It's better to have some reading value and deep thinking. The book list is not long. It's only for the introction of popular science

In fact, after going to university, many people have an idea, that is to make money
How to make money? To introce you to several ways (insist, otherwise don't look down)
1, counterpart major , making money in learning is the most reliable. For example, if you are a teacher major, you can choose to tutor; Design class can find a treasure, to consult the repair map, shooting class work
2, words make money ! According to your ability, you can contribute to the official account. Generally, 2000-3000 words can receive a fee of several hundred dollars. Of course, it depends on your own skills and the preferences of the article. p>
3, earn money part time ! You can pay more attention to the part-time group of the school, generally there will be the kind of leaflets, daily salary ranging from 100-120, a little hard, also can be regarded as a kind of training for yourself
the above is a personal summary, but in any case, we need to stick to it. Money is not from strong winds, but from hard work. Come on, pay homage to everyone who wants to make money. In addition, we must pay attention to high profit work and be alert to avoid falling into pyramid schemes
many people think that electromagnetic waves must also be transmitted through a medium, but human beings have not yet found any medium, so scientists guess that there is a medium, and named it "Ether"
2 In optics, we think that the speed of light is constant (but I think there is an error in the explanation)
I think that it is correct to see that the speed of light in the same direction of motion becomes slower, on the contrary, it becomes faster. But at present, there is no speed close to the speed of light, so the feeling is not obvious. This view has nothing to do with the existence of "Ether"
3. At present, many viewpoints in the field of optics are conjectures or ideas. I hope that we can not limit the existing textbooks, but strive to put forward some new opinions on each experiment, because even the theory that is very recognized now may be overturned in the future. Just like Einstein's theory of relativity, many of its conclusions are conceived, and there is no powerful experiment or evidence to prove them, so don't trust the theory too much
for example, what you said on the second floor is something in the theory of relativity. In fact, what you said has not been confirmed. Maybe you are the next Einstein, and today's Einstein and Hawking may become the second Aristotle in physics. ~~

What does "a survey of psychology in the 20th century" tell us< It is said that psychology shoulders the mission of exploring the source of human happiness; It is said that psychology is like a shark. Fate plunges it into the torrent of change, development and challenge. It only keeps swimming forward, or it will die. So, what fields has psychology been involved in? What theories have been put forward? What organizations have been established? What problems have been solved“ With its mature language, interesting cases and profound wisdom, "a survey of psychology in the 20th century" answers the above questions one by one
"a survey of psychology in the 20th century" is an exhibition of the development of psychology in the 20th century. The civilization course of compiling psychology can be divided into "old history" and "new history"“ "Old history" is a "top-down history", which focuses on great people and events, also known as "great history". The essence of the history of great men is to praise the psychologists who reveal the mysteries of mind and behavior, and introce their thoughts and ideas“ "New history" is a "bottom-up history", which attempts to describe the lives of unknown people, focusing on the social background, cultural origin and human activities of the establishment and development of psychology, also known as the "spirit of the times". The essence of the spirit of the times is to use first-hand information rather than anecdotes, which tends to analyze the background of events and social needs“ "A survey of psychology in the 20th century" attempts to integrate the topic selection styles of the new and old histories, taking into account not only one school, one family, one person and one theory that have great influence on psychology, but also the social background of these schools, theories and scholars
"a survey of psychology in the 20th century" is a collection of ideas about psychology in the 20th century. The authors selected for this series are first-class scholars with great prestige in various fields of psychology, such as Watson, founder of behaviorism, tixiner, founder of constructivism, mcdougu, founder of social psychology, kaufka, founder of Gestalt psychology, Lewin, founder of topological psychology, Rorschach, founder of ink test, etc. They come from all over the world and have a high reputation in the application of professional theories to social life. The thoughts of these scholars not only show us a beautiful picture which is rarely seen at ordinary times, but also have a profound impact on other disciplines related to psychology
"a survey of psychology in the 20th century" is an extraordinary work that uses psychology to explore the hot issues of human beings in the 20th century. In designing the series, the editor linked the development of psychology with the hot issues of human beings. It begins with the main trend of thought in psychology, and then discusses the similarities and differences between animal psychology and human psychology, whether human indivials have the potential desire for power intention, how different indivials form their life style, whether people can reach the highest stage of self-development, what are the weaknesses of human nature In social life, should indivials be "hedgehog" or "Fox", what kind of curve human learning presents, which stage is the crisis stage of life development, and how people build their own "personal field" and so on. All these hot issues not only emphasize the importance of human psychology, but also reveal the limitations of human psychology. The series comprehensively discusses the problems of survival, cooperation, creation and development
the "20th century psychology survey" is called "classic" not only because every book in the series is written by everyone, but also because every argument in each book is supported by scientific experiments. It can be said that without the basic skills of "Mastering thousands of songs and then listening to them, and observing thousands of creations and then recognizing them", we can't write them< There are 28 kinds of "a survey of psychology in the 20th century"
"a treatise on human and animal psychology", "animals and human purposeful behavior", "Introction to social psychology", "human motivation: metaphor, metaphor, psychology and psychology" Theory and research, psychological diagnosis, cognitive dissonance theory, Gestalt psychology principles, developing self, human ability, topological psychology principles, psychological test, thinking and language, system Psychology: introction, behaviorism, organism theory, human learning, personal structure psychology, on human nature, and authoritarian personality Self development, memory: an experimental and psychological study, identity: adolescents and crisis, basic and applied psychology, history of psychology, interpersonal theory in psychiatry, wisdom of apes, personality and psychotherapy, principles of perceptual learning and development, are difficult to consider, More theories
