Science and technology are two very closely linked fields of study that are concerned with the study of science, the way it works and how it affects the world around us. Science is a branch of knowledge that deals primarily with the natural sciences and includes such areas as biology, chemistry, physics, astronomy, and the physical sciences.
Science also deals with the study of nature. Science covers the systematic study of nature through observation and experimentation, and it is this study that forms part of what we know as science. Science is divided into two broad sections: natural sciences, which deal mostly with the physical and biological world; and applied sciences, which include engineering, law, economics, health care, computer science, and social sciences. A great example of a natural science is cosmology, which studies the laws of nature and its relationship to the universe.
The process of science is complicated, requiring a great deal of observation, experimentation, and observation in order to prove or disprove theories. As such, there is often much disagreement about various theories within science; the results of these disputes often give rise to new and often competing theories.
Some basic aspects of science include observation, experimentation, and hypothesis testing. When a scientific theory is put forward, it must be able to provide a well-defined explanation of certain facts and circumstances. If the theory cannot make this claim, then it is not a valid scientific theory. For example, if scientists were to propose a theory about the origin of the universe, but they failed to properly explain its position in relation to the stars, then their theory would be invalidated.
In addition to the basics of science, there are also other advanced aspects of science that are used in more modern situations, such as the study of quantum mechanics. Quantum mechanics concerns the structure of sub-atomic particles and forces in the universe and their interactions with each other. There are a number of different theories, all of which can be used to explain the various effects of quantum mechanics and what its implications are on the universe.
Science is an ever-evolving field, with a number of branches of natural sciences and several applied sciences taking up space in the grand scheme of things. There are also many branches that deal with the interaction of humans with the environment. Such areas include philosophy, religion, and psychology.
