Three Branches of Science

Science is such a wide area that it is divided into branches. Biology, chemistry and
geology are three of these branches. Each branch of science are very different. They use
many of the same techniques in the study of the materials in their area of science, but
are very different materials.
Biology is the study of life and living things. The French naturalist, Jean Baptiste,
introduced the term, biology, in Germany during the 1800's. Biology is also divided into
branches. Zoology, botany and anatomy are three of the major branches. Biology studies
the life of particular species and their behavior, development and history. What makes
biology different from the other branches of science is that it studies living things. 
Chemistry is the branch of science dealing with the properties, composition and structure
of substances and the changes they undergo when they combine or react under specific
conditions. Chemistry deals mainly with components of material origin. Organic chemistry
is the only branch of chemistry defined as the study of substances produced by living
organisms. Physical chemistry is concerned with the physical properties of materials.
Chemistry deals with the states of matter. Through experimentation a chemist defines a
material by how it reacts under many different situations and how it reacts to other
materials. From the earliest recorded times, humans have observed chemical changes and
have speculated at their possible causes. By following the history of these observations
and speculations the gradual evolution of the ideas and concepts that have led to the
modern science of chemistry can be traced. In recent times, a great deal of research has
been at the atomic and molecular levels. The study of their reactive characteristics has
led to great advances in the use of the power of their reactions in the creation of
nuclear power. 
Geology is the science of the Earth's history, composition and structure. Geological
observations have been made since ancient times. The branches of geology are divided
between the study of the Earth's landforms, petrology, geochemistry, geophysics,
structural geology and paleontology. Geology encompasses the study of the Earth's
landforms and it's surface features but is also concerned with the structure and inner
parts of the planet. The focus of applied geology is to search for useful minerals,
stable environments for human constructions and identify natural hazards. Oceanography is
a branch that studies the ocean floor, mapping and measuring the Earth's surface and
searching for clues to the origin of Earth.
As you can see, these three branches of science are very different. They each involve the
research of very different materials present here on Earth. They study living and
non-living substances. The common thread is the science focused on the goal of finding
and understanding these materials and how they can make life better for us. Scientists
have searched for and studied various materials found on Earth. By studying the reactions
in different environments, all branches of science have been able to develop the
resources found on Earth to improve the status of living in society today. Each branch of
science is focused on a grouping of materials that are very different in their
characteristics, but the scientist's goals are very much the same. They seek to come to
the best understanding of the possibilities that each offer to the human race.
