Recently, I have seen my friends who do n’t know the words below very much about the word science through comment.
Science is a knowledge system that explores nature through observation, experiments and logical reasoning.Its goal is to understand the nature and laws of everything, so that humans can better grasp and control the power of nature to meet the needs of human society.Scientific research areas are very wide, including physics, chemistry, biology, earth science, social science, and so on.
Scientific classification can be performed from different angles.From the perspective of research objects, science can be divided into three aspects: natural science, social science and humanities.Among them, the non -human world is studying natural science, mainly including physics, chemistry, biology, earth science and so on.Social science research human society mainly includes economics, political science, sociology, psychology, education, etc.Humanities are also the field of humanity, but it emphasizes the aspects of human culture, such as history, literature, art history, and so on.
From the perspective of research methods, science can also be divided into two aspects: experimental science and theoretical science.Experimental science refers to verification and confirmation of scientific hypothesis and theories through experiments.Theoretical science refers to establishing and explaining scientific theory and principles through logical thinking and reasoning.These two methods are very important in scientific research. They support each other and jointly promote scientific progress.
The origin of science can be traced back to ancient Greece in the 6th century BC, and mathematicians, physicist Pittergras, Archimedes, Aristotle and others laid a foundation for the development of science.However, the real scientific revolution began in the 17th century. With the emergence of scientists such as Copernicus, Galileo, and Newton, the basic theory and experimental methods of scientific research gradually established.Since then, scientific research has been rapidly developing and popularized, and has made great contributions to human society.
The results of scientific research are widely used in various fields of human society.Among them, the development of natural sciences such as physics and chemistry has promoted the rapid development of modern technology, such as power, communications, transportation, agriculture, medical and other fields.The development of biology helps mankind to better understand the knowledge of human health and disease prevention.Social science research helps people better understand the operating mechanism of human society, which is of great significance for humans to achieve fair, stable, and harmonious development.
