There are three main divisions of science: physical science, life science, and earth science. However, there are many subdivisions that also overlap, such as physical chemistry, astrophysics, organic chemistry, and astrogeology. These sub divisions overlap because they are require a knowledge of at least two main divisions of science.Know More
Science is defined as a branch of knowledge about the study of the natural world through observation and scientific method. Although observations seen on a daily basis are broken down into three main divisions, they are also categorized in different ways. For example, a science can be categorized as pure or theoretical. Pure science explains a phenomenon while theoretical science is based on hypothetical deductive methods.
Physical sciences, such as physics and chemistry, are related to matter and energy and describe the physical universe in objective measurements. Earth sciences, geology and astronomy, are related to earth, its geological and atmospheric phenomena, and its solar system. Life sciences, biology and botany are related to all living organisms and their relationship to one another and their environment.
Each main division of science is categorized as a pure science, however, when subdivisions overlap and new compound sciences emerge, theoretical sciences are created to form studies such as paleontology and astronautics.Learn more about Science
The two main branches of physical science are physics and chemistry. Physics primarily deals with forces and the interaction of matter and energy. Chemistry, on the other hand, studies how interaction alters the properties of atoms, molecules and substances.Full Answer >
In physical science, time is defined as a measurement, or as what the clock face reads. With the advent of atomic timekeeping and the International System of Units, time is measured in units of seconds and held to the standards of the UTC time stamp.Full Answer >
Astronomers need a very advanced education, including an undergraduate degree in a physical science or mathematics and a master’s degree in an astronomy-related field. Most working astronomers have a doctorate in their specialty as well. However, most hopeful astronomers get the chance to work in the field while attaining their advanced education.Full Answer >
Scientists conduct a variety of research in Antarctica, including studies on climate change, astronomy, geology, earth science, marine biology and astrophysics, according to WonderfulAntarctica.com. The continent's forbidding environment, with winter temperatures dropping as low as 76 degrees below zero and summer temperatures rising to approximately 32 F, and its lack of native population make Antarctica a choice location for scientists to study the forces of nature in pure, untouched terrain.Full Answer >
