Is getting a doctorate in chemistry the way out?

Knowledge expansion:

Chemistry is a basic natural science that studies the composition, structure, properties, transformation and application of substances at the atomic and molecular levels. It originates from life and production practice, and develops with the progress of human society.

Different from the smaller particle physics and nuclear physics, chemistry studies the material structure of atoms, molecules and ions (groups) and the interaction between chemical bonds and intermolecular forces.

Its scale is the closest to the macro in the micro world, so their natural laws are closely related to the physical and chemical properties of substances and materials in the macro world of human life. As an important bridge between the micro and macro material world, chemistry is one of the main ways and means for human beings to understand and transform the material world.

Chemistry is a natural science that studies the composition, structure, properties and changing laws of substances at the atomic level, which is also the core basis of chemical changes. Chemistry is a natural science based on experiments. The word "chemistry" in Chinese, if interpreted literally, is "changing science". Chemistry, like physics, is the basic science of natural science.

Mendeleev's periodic table of chemical elements greatly promoted the development of chemistry. Nowadays, many people call chemistry "central science" because chemistry is the core of some scientific disciplines, such as materials science, nanotechnology, biochemistry and so on. There are five and two disciplines in modern chemistry: inorganic chemistry, organic chemistry, physical chemistry, analytical chemistry and polymer chemistry.

Chemistry is one of the important basic sciences and a subject based on experiments. It develops rapidly with the mutual penetration of physics, biology, earth science, astronomy and other disciplines, and also promotes the development of other disciplines and technologies. For example, the research results of nucleic acid chemistry have raised biology from cellular level to molecular level and established molecular biology.

The historical origin of chemistry is very old. It can be said that the earliest chemical practice began when humans learned to use fire. Our ancestors drilled wood for fire, roasted food with fire, kept warm in cold nights and drove away wild animals, making full use of the phenomena of light and heat during burning.
