Is it really 21st century science?

About the subject itself

I have asked many of my peers why they study biology, and the most common answers I get (including myself) are failed attempts at medicine. Medical school scores are very high, in addition to high clinical medicine, oral ophthalmology scores are well ahead of their school's basic admission scores.

In order to maximize the advantages of their scores and go to a good university, we bear the pain and abandon the medical theory, trying to save the country, can not personally go to the operating table to help the world, behind the scenes to study the activity of life itself, to explore the mystery of life is also interesting. Therefore, we have embarked on the road of life science, the "century discipline" of the 21st century.

In fact, the difference between life science and medicine is still relatively large, the former pays attention to practical operation, the latter tends to theoretical research.

Life science belongs to science and engineering in the college entrance examination and belongs to natural science. Although middle school biology requires cumbersome and illogical memory compared with other subjects such as mathematical physics, it still belongs to the science of exploring the field of nature and is a systematic knowledge system in the field of life, which can obtain specific and repeatable experimental results through experimental verification.

In terms of research content, life science is a science that studies life phenomena, reveals the law and nature of life activities, and the relationship between various biological systems.

The knowledge structure of the subject

1. Undergraduate course system

The main curriculum varies from institution to institution.  Therefore, the first two semesters are the best time to change majors, at this time there is little difference in everyone's training plans, the content that needs to be made up is relatively small, and it is easy to keep up with the new professional arrangement.

According to the chronological order and depth of knowledge, the curriculum arrangement of life science majors in the undergraduate stage is roughly included

Professional basic courses: mainly distributed in freshman and sophomore years, including

· Mathematics and Physics courses: Advanced Mathematics, linear algebra, probability statistics, university physics and experiments.

· Other basic courses: Basic computer science, vb or C language, inorganic chemistry, analytical chemistry and experiments. In the sophomore year, I continued to study organic chemistry, physical chemistry and their experiments.

Core professional courses: I started to contact with them after my sophomore year. The most core courses include biochemistry, genetics, molecular biology and its experiments. On this basis, there will be some differences in curriculum arrangement between science and engineering life science departments.

In the more scientific departments, the training program will arrange other theoretical and experimental courses will be relatively more. For example, the curriculum of Tsinghua University includes general biology, cell biology, physiology, developmental biology, immunology, animal physiology experiment, molecular biology experiment, cell biology experiment, biophysics, neurobiology, bioinformatics, basic biostatistics, molecular mechanism of major diseases, biological research of brain diseases, genomics and epigenomics.

In the engineering department, it is necessary to spend more energy to learn engineering drawing, chemical principles, biological engineering, cell engineering, genetic engineering and other engineering courses.

The training purpose of the life science department is to enable students to systematically and solidly grasp the basic knowledge, basic theories and basic skills of biology, master the basic methods and means of biological science research, have a strong sense of innovation and practical ability, and have a deep understanding of the frontier and development trend of biology. Understand the basic knowledge of life, materials, energy, environment and other related disciplines, and be able to engage in scientific research, technology, education and other work in biological science and related fields.

The training purpose of the life science department is to enable students to systematically master the basic knowledge, basic theories and basic skills of biology, and enable them to systematically master the knowledge of bioengineering and biotechnology practice and have strong ability of engineering practice, research and development and design. Be able to engage in research, development and industrial production in the field of biotechnology, bioengineering and related disciplines.

2, subdivision direction and interdisciplinary

Biology is divided into many categories, according to different classification methods, corresponding to different subdivisions. In the Ministry of Education's undergraduate directory, under the Science directory, there is the Biological Sciences category, which has six majors: Biological sciences, biotechnology, bioinformatics, ecology, integrative Sciences, and neuroscience.
