common theory, scientific theory and scientific law: What is the difference?

A scientific theory is not equal to a common theory and is also different from a scientific law. Although the media and in everyday language can talk very casually over again and new theory, within the context of science these terms have a different meaning, which often causes confusion. Largely due to the ignorance of the American public regarding the precise definition of these terms in the SCIENCE, he was born a whole against the theory of evolution, which is considered a fact and forms the basis of biology movement. It is practically denying that the Earth revolves around the sun. To avoid falling into such errors, it is important to recognize the differences between the meaning of “theory” in science and society, and know also how it relates to the hypotheses and scientific laws.

In common parlance when we speak of a theory, we mean an idea or proposal that has not yet been proven.

Simplified, we can think so

To understand more precisely, let us examine the meaning of each term more detail

It is a scientifically supported explanation of how some phenomenon works. The word theory in this case does not indicate insecurity or lack of knowledge, a scientific theory is not a guess.

A scientific theory describes the mechanisms of how a natural process works, what causes it and how it works under different circumstances. Our knowledge of these mechanisms is completely based on facts, observations and conclusions and verified by many independent researchers; only under this circumstance can be considered a scientific theory.

In some cases, there may be competing scientific theories and contradict one another. This happens when the evidence supports all theories and still do not have the technology needed to know which of these is correct. So theories are fully supported by the data and evidence we have our technological reach, however it is known that these theories are confirmed, amended or deleted according to the information that we collect when we have the most advanced technology. This is the case in the fields of astrophysics and quantum physics, where distances are so big and so small (respectively) we can not observe the events directly.

It is an irrefutable description of an action or set of actions. Scientific laws often are expressed as a formula or a group of mathematical formulas that describe the action or set of actions.

Whereas science itself is a whole body of knowledge we have, laws and theories that constitute are intimately linked. Laws and scientific theories support each other. For example

On the contrary, all we know in science are set as adding new knowledge to this body of evidence. Currently we believe that the scientific laws and theories are true, but anyway we may have to be adjusted over time, according to the advances in technology that allow us to have more accurate powers of observation.
