Classification of science I

General Classification of Science

The main branches of science are commonly divided into two major groups:

  • Social sciences, It is the study of human behavior and societies.
  • Natural sciences, It is the study of natural phenomena (including fundamental forces and biological life).
  • Natural sciences are further classified into three main groups.

Physics: It is the study of matter and energy and the interactions between them. In physics scientists focuses on laws and properties that govern behavior of all matter. Physics often involves things we can't see or touch, but can prove, like gravity. We can't see or touch gravity, but because of years of experiments, we know it's there. Physicists also study energy, mechanics, motion, waves, electricity, nuclear reactions, and forces. People interested in physics use scientific laws and theories to build some of the things we see everyday, like bridges, cars, buildings, and power plants. If it's a structure or involves a motor, physics was surely considered when creating it. Albert Einstein was one of the most famous physicists to date. He developed the theory of relativity, which is the basis for black holes and the potential for time travel, as well as how matter is converted to energy, which is used in nuclear power plants.

Chemistry: It is the branch of science that deals with the composition, properties, reactions, and the structure of matter. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach. Chemistry involves how atoms, the smallest particles of the world, bind together to create compounds. Although this might seem minor, chemistry is responsible for nearly any household product you use. Hair care products, cleaning products, even the packaged foods you eat, are all based in chemistry. For example, in the lab, scientists use chemical reactions to make compounds that smell like certain natural foods. One of the earliest discoveries was methyl anthranilate, a compound that smells like grapes and was one of the original ingredients in grape Kool-Aid.

Other chemists had a more significant impact on the world. Marie Curie was the first to discover two new radioactive elements and to use radiation to treat cancerous tumors. Her work revolutionized medicine. Unfortunately, she eventually died of radiation exposure. Before her death, she received a Nobel Prize in Chemistry, one of the most esteemed awards for scientists. The chemist Louis Pasteur, discovered pasteurization.

Earth sciences;

            Earth science (also known as the geosciences) is a term for the sciences related to the planet Earth. It is arguably a special case in planetary science, the Earth being the only known life-bearing planet. Earth sciences may include the study of the atmosphere, hydrosphere, lithosphere and biosphere. Typically Earth scientists will use tools from physics, chemistry, biology, geography, chronology and mathematics to build a quantitative understanding of how the Earth system works, and how it evolved to its current state.
