Biology is studies the science of biological phenomena, the essence of vital movement and characteristics. It can be used to effectively control life activities and actively transform the biological world for the benefit of mankind. Biology is closely related to human survival, health, economic construction and social development. It is the most fundamental natural science in the world today.
It is mainly the observation and description of nature, and it is about the study of natural history and morphological classification. Therefore, biology was the first divided into groups according to groups, such as botany, zoology, and microbiology. Due to the diversity of biological species and the increasing understanding of biology, the division of disciplines is becoming more and more detailed. A discipline is often divided into several disciplines. For example, botany can be divided into algae, zoology is divided into entomology, ichthyology, ornithology; microbes are not a natural group of organisms, just an artificial division, all tiny creatures such as bacteria Single-cell fungi, algae, and protozoa can be called microorganisms, and viruses without cell morphology can also be included in microorganisms. Microbiology is divided into bacteriology, mycology, virology.
Astronomy is the science of studying the structure and development of the universe. The content includes the structure, nature and operational laws of the celestial body. Mainly by observing the radiation by celestial bodies to the Earth, discovering and measuring their position, exploring their movement laws, studying their physical properties, chemical composition, internal structure, energy sources and their evolution.
The study of astronomy has great practical significance for our life and has a great influence on the natural view of human beings. Ancient astronomers determined time, direction, and calendar by observing the sun, the moon, and other celestial bodies and celestial phenomena. This is also the beginning of astrometry. The history of astronomy has been at least five or six thousand years since we began to observe celestial bodies. Astronomy occupies a very important position in the early history of human civilization. The Pyramids of Egypt and Stonehenge in Europe are famous prehistoric astronomical sites.
- Earth Science
Earth science is the science of researching on the processes and changes of the Earth system (including the atmosphere, the hydrosphere, the lithosphere, the biosphere, and the solar-terrestrial space). It mainly includes such as geography (including soil science and remote sensing), geology, geophysics, geochemistry, atmospheric science, marine science and space physics, and new interdisciplinary (earth system science, earth information science).
