Physical science is an encompassing term for the branches of natural science, and science (generally), that study non-living systems, in contrast to the biological sciences. However, the term "physical" creates an unintended, somewhat arbitrary distinction, since many branches of physical science also study biological phenomena. Note that neither mathematics nor engineering belong to the sciences. Basic physical science topics include:

  • Astronomy - the study of the universe beyond the atmosphere of the Earth
  • Chemistry - the science dealing with the composition of substances, their interactions with energy and each other
  • Many of the earth sciences, including:
    • Geology - the study of the planetary structure of Earth and the physical processes which shape it
    • Hydrology - the study of the movement and distribution of water across the Earth's surface
    • Meteorology - the study of weather patterns and other atmospheric phenomena
    • Oceanography - the study of the ocean as a physical system
    • Soil science - the study of the pedosphere
  • Physics - the quantitative science dealing with matter and energy

[edit] Basic principles of the physical sciences

The foundations of the physical sciences rests upon key concepts and theories, each of which explains and/or models a particular aspect of the behavior of nature. As in other sciences, these key concepts and theories came to discovery using the scientific method, which must be found using scientific evidence:

[edit] Basic principles of astronomy

Astronomy is the science of celestial bodies and their interactions in space. Its studies includes the following:

(Note: Astronomy should not be confused with astrology, which assumes that people's destiny and human affairs in general are correlated to the apparent positions of astronomical objects in the sky -- although the two fields share a common origin, they are quite different; astronomers embrace the scientific method, while astrologers do not.)

[edit] Basic principles of chemistry

Chemistry is the science of matter mainly at the micro-level. Its studies include the following:

[edit] Basic principles of earth science

Earth science is the science of the planet Earth, the only known life-bearing planet. Its studies include the following:

[edit] Basic principles of physics

Physics is the "fundamental science" because the other natural sciences (biology, chemistry, geology, etc.) deal with systems that obey the laws of physics. The physical laws of matter, energy, and the forces of nature govern the interactions between particles (such as molecules, atoms, or subatomic particles). Some basic principles of physics are:
