What does science say? Definition of science
Science is the name given to the systematic, systematic study of all things that can be observed, tested, and verified in the physical world. But to make it easier to understand, we need to know the meaning of the word "science."
Need to know the meaning.
The word science is a Bengali translation of the English word 'Science'. The word science comes again from the Latin word 'Scientia', which means knowledge. Analyzing the word science in Bengali gives B + knowledge, which means special knowledge. That is, special knowledge about a subject is called science. Now the question may arise what is this "special knowledge" again! This "special knowledge" is the systematic, systematic study of all that is observable, testable, and verifiable in a physical world, and that researched knowledge-
Therefore, science is only when we do extensive research or experiment on a subject and gain systematic or systematic knowledge by observing and verifying that research or experiment. Again, we call those who acquire this special knowledge scientist
Branch of science
One of our common questions is, how many types of science? Science cannot be divided into such 'types'. However, there are different branches of science. These branches of science can be further divided into different parts.
There are three main branches of science. These are-
- Natural science
- Social science
- General Science
However, there is some disagreement as to whether general science is a branch of science at all.
The natural sciences and social sciences are also called research sciences. - Natural Sciences: Natural sciences are primarily concerned with research evidence for the description, prediction, and interpretation of the phenomena of nature. All this research evidence is prepared through various experiments. Natural science can be divided into two main parts-
- Biology: Biology is a branch of natural science that researches organisms and life. This branch of science deals with the formation, growth, evolution, and taxonomy of organisms. There are different branches of biology. Eg zoology,
- ঃ Physical Science: The branch of natural science that deals with various theoretical topics is called physics. However, the truth of these theoretical matters is proved by various experiments and mathematical calculations. This branch of natural science can be divided into different classes. However, basically,
physics can be divided into major categories like physics, chemistry, astronomy, geology, etc.
- • 3. General Science: The branch of science that deals with the basic subjects of science such as logic, mathematics, etc. are called general science. The branches of general science are logic, mathematics, computer science, and statistics.
- Applied science
- Applied science is a practical aspect of theoretical science. When scientific knowledge is applied in practice, it is called applied science or applied science. It is a branch of science in which practical application of existing scientific knowledge is made. In the natural sciences, special knowledge is acquired through research, experiments, or calculations on various theories of nature. And when all this acquired knowledge is applied in practice, it is called applied science. Such as different types of technology and equipment.
- Science education
- Science education is the teaching and learning of science to non-scientists such as school children, college students, or adults in general. That is, those of us who are learning science from different educational institutions, so science education.
