Science is the pursuit and application of: knowledge and understanding of the natural and social world following a systematic methodology based on evidence. Natural science is the study of the physical world: life science and physical science. These two branches may be further divided into six disciplines. Life science as: biology and environmental; and physical science as: astronomy, chemistry, earth science, and physics.

  • Astronomy
  • Biology
  • Chemistry
  • Earth Science
  • Environmental
  • Physics


The study of celestial object, space, and the physical universe as a whole. It uses: mathematics, physics and chemistry in order to explain their origin and evolution. Basic objects of interest include: asteroids and comets, moons, planets, and stars. More complex objects include: nebulae, pulsars, quasars, star clusters, black holes, galaxies, and dark matter.


The study of living organisms and their vital processes, which can be divided into many specialized fields that cover their: morphology, physiology, anatomy, behavior, origin, and distribution. Specialized fields in biology include: anatomy, biochemistry, biophysics, biotechnology, botany, cell biology, ecology, evolution, genetics, immunology, marine biology, microbiology, molecular biology, mycology, parasitology, physiology, theoretical (mathematical) biology, virology and zoology.


The study of the structure of substances (elements and compounds): their properties, composition, the transformations they undergo, and the energy that is released or absorbed during these processes. The technical disciplines are: analytical, environmental, inorganic, organic, physical and polymer chemistry. There are also hybrid fields such as: astrochemistry, chemical biology, chemical engineering, chemical physics, cheminformatics, and geochemistry.

Earth Science

Earth Science or Geoscience includes all fields of natural science related to the planet Earth. It is dealing with the physical and chemical properties of the Earth and its atmosphere. Which include: geologic, hydrologic, and atmospheric sciences with the broad aim of understanding Earth’s present features, and past evolution to use this knowledge to benefit humankind.


Environmental Science is the study of the physical, chemical and biological processes, that take place on Earth, as well as the social, political and cultural processes which impact the planet. The major branches include: atmospheric science, ecology, environmental chemistry, and geosciences. Popular topics include: alternative energy systems, pollution control and mitigation, natural resource management and the effects of global climate change.


Physics means the knowledge of nature. It is one of the most fundamental scientific disciplines, and its main goal is to understand the behaviour of the universe. Physics as we know it today is the natural science that studies: matter, its motion and behaviour through space and time, and the related entities of energy and force. It is often expressed in the universal language of Mathematics. Within physics there are several branches: classical mechanics, relativistic mechanics, molecular physics, atomic physics, condensed matter physics, cosmology, electromagnetism and photonics, high energy particle physics, nuclear physics, optics, quantum mechanics, statistical mechanics, and thermodynamics. There are also several interdisciplinary studies within physics as well.
