Define the Term Law in Science

«There are four main concepts in science: facts, hypotheses, laws, and theories,» Coppinger told WordsSideKick.com. The postulates of special relativity are not «laws» per se, but assumptions of their nature in relation to relative motion. Our editors will review what you have submitted and decide if you want to review the article. Science uses technical terms that have different meanings than everyday use. These definitions correspond to how scientists generally use these terms in the context of their work. In particular, note that the meaning of «theory» in science is different from the meaning of «theory» in everyday conversation. Scientific laws are usually conclusions based on repeated scientific experiments and observations over many years that have been widely accepted in the scientific community. A scientific law is «derived from certain facts that are applicable to a defined group or class of phenomena and can be expressed by the assertion that a particular phenomenon occurs whenever certain conditions are present.» [7] Creating a summary description of our environment in the form of such laws is a fundamental goal of science. In science, claims of impossibility are widely accepted as extremely likely and not considered proven, to the point that they are not questionable. The basis of this strong acceptance is a combination of extensive evidence of something that does not happen, combined with an underlying theory that makes predictions very well whose assumptions logically lead to the conclusion that something is impossible. Although a scientific claim of impossibility can never be absolutely proven, it could be refuted by observing a single counter-example.

Such a counterexample would require that the assumptions underlying the theory that implied impossibility be re-examined. Scientific laws or laws of science are statements based on repeated experiments or observations that describe or predict a number of natural phenomena. [1] The term law has in many cases a variety of uses (approximately, exactly, widely or narrowly) in all areas of the natural sciences (physics, chemistry, astronomy, earth sciences, biology). Laws are made from data and can be developed through mathematics; in all cases, they are based directly or indirectly on empirical results. It is generally accepted that they implicitly reflect causal relationships, although they do not explicitly claim that they are fundamental to reality, and that they are discovered rather than invented. [2] More modern laws of chemistry define the relationship between energy and its transformations. The term «scientific law» is traditionally associated with the natural sciences, although the social sciences also contain laws. [11] For example, Zipf`s law is a law in the social sciences based on mathematical statistics. In these cases, laws may describe general trends or expected behaviors instead of being absolute. Scientific laws or laws of science are statements based on repeated experiments or observations that describe or predict a number of natural phenomena.

The term law is used differently in many cases (approximately, accurately, widely or narrowly) in all areas of the natural sciences (physics, chemistry, astronomy, earth sciences, biology). Laws are made from data and can be developed through mathematics; in all cases, they are based directly or indirectly on empirical results. It is generally accepted that they implicitly reflect causal relationships, although they do not explicitly claim that they are fundamental to reality, and that they are discovered rather than invented. Scientific laws summarize the results of experiments or observations, usually in a specific field of application. In general, the accuracy of a law does not change when a new theory of the relevant phenomenon is developed, but the scope of the law, since the mathematics or statement that the law represents does not change. As with other types of scientific knowledge, scientific laws do not express absolute certainty, as do mathematical theorems or identities. A scientific law can be refuted, limited or expanded by future observations. A law can usually be formulated in the form of one or more statements or equations in order to be able to predict the outcome of an experiment. The laws differ from the assumptions and postulates proposed during the scientific process before and during validation through experience and observation. Assumptions and postulates are not laws, as they have not been verified to the same extent, although they may lead to the formulation of laws. Laws are narrower than scientific theories, which may include one or more laws.

Science distinguishes a law or theory from facts. Calling a law a fact is ambiguous, an exaggeration or an ambiguity. The nature of scientific laws has been much discussed in philosophy, but in essence, scientific laws are simply empirical conclusions drawn by scientific methods; They must not be burdened with ontological obligations or statements of logical absolutes. The difference between scientific laws and scientific facts is a little more difficult to define, although the definition is important. The facts are simple and basic observations that turned out to be true. Laws are generalized observations about a relationship between two or more things in the natural world. The law may be based on facts and hypotheses tested, according to NASA. Is a scientific rule in the form of words or a mathematical formula that uses precise data, information or facts with evidence to describe a cause and effect of a facet of science in the universe. Laws are constantly being tested experimentally with increasing accuracy, which is one of the main goals of science. The fact that it has never been observed that laws have been violated does not prevent testing them with increased accuracy or under new conditions to confirm whether they continue to apply or if they break and what can be detected in the process. It is always possible that laws may be declared invalid or proven to have limitations, through reproducible experimental evidence, where appropriate. Well-established laws have indeed been declared invalid in some particular cases, but the new wording created to explain the discrepancies generalizes the originals rather than overturning them.

That is, invalid laws have turned out to be only close approximations, to which other terms or factors must be added to cover previously inconsiderate conditions, such as very large or very small time or space scales, enormous velocities or masses, etc. Therefore, physical laws are not seen as immutable knowledge, but as a set of improved and more accurate generalizations. A law in science is a generalized rule for explaining a series of observations in the form of a verbal or mathematical statement. Scientific laws (also known as laws of nature) imply cause and effect between the observed elements and must always apply under the same conditions. To be a scientific law, a statement must describe an aspect of the universe and be based on repeated experimental evidence. Scientific laws can be expressed in words, but many are expressed as mathematical equations. Other postulates change the idea of physical observables; the use of quantum operators; some measurements cannot be made at the same time (principles of blur), the particles are basically indistinguishable. Another postulate; The postulate of the collapse of the wave function contradicts the idea of a common measure in science.

of the physical system between two times t1 and t2. The kinetic energy of the system is T (a function of the rate of change of the system configuration), and the potential energy is V (a function of the configuration and its rate of change). The configuration of a system with N degrees of freedom is defined by generalized coordinates q = (q1, q2,. qN). A scientific law is a statement based on repeated experimental observations that describes an aspect of the world. A scientific law always applies under the same conditions and implies that there is a causal relationship that affects its elements. Factual and well-confirmed claims such as «mercury is liquid at standard temperature and pressure» are considered too specific to be considered scientific laws. A central problem in the philosophy of science, dating back to David Hume, is the distinction between causal relationships and principles that arise by constant conjunction. Laws differ from scientific theories in that they do not postulate a mechanism or explanation of phenomena: they are only distillations of the results of repeated observations. As such, a law is limited in its applicability to circumstances similar to those already observed and may prove to be false when extrapolated. Ohm`s law applies only to linear lattices, Newton`s law of universal gravity applies only to weak gravitational fields, early laws of aerodynamics such as Bernoulli`s principle do not apply to compressible flow as it occurs in transsonic and supersonic flight, Hooke`s law applies only to deformations below the elastic limit, etc. These laws remain useful, but only under the conditions under which they apply.

Another example where mathematics influences scientific law is that of probability. «My favorite scientific law is that we live in a probabilistic world, not deterministic. With large numbers, probability always works. The house always wins,» said Dr. Sylvia Wassertheil-Smoller, a professor at albert Einstein College of Medicine. «We can calculate the probability of an event and we can determine how confident we are from our estimate, but there is always a trade-off between accuracy and safety.
