Scientific Laws: Provable Or Not?

Scientific laws are statements that describe or predict a range of natural phenomena based on repeated experiments or observations. They are developed from data and can be formulated as one or several statements or equations. While they are well-supported by observations and experimental evidence, they do not express absolute certainty and may be contradicted, restricted, or extended by future observations. The applicability of a law is limited to circumstances resembling those already observed, and the law may be invalidated or proven to have limitations under new conditions. This raises the question: can a scientific law be proven?

Scientific laws are not absolute

Additionally, laws differ from scientific theories in that they do not explain phenomena but are distillations of the results of repeated observations. As such, the applicability of a law is limited to circumstances resembling those already observed, and the law may be found to be false when extrapolated. For example, Ohm's law only applies to linear networks, and Newton's law of universal gravitation only applies in weak gravitational fields. These laws remain useful, but only under specified conditions.

In summary, scientific laws are not absolute. They are based on empirical evidence and are subject to change with new observations, conditions, or more accurate laws. They are a process of refining our understanding of the world and are not absolute truths.

Scientific laws can be contradicted

Scientific laws are based on repeated experiments or observations and describe or predict a range of natural phenomena. They are typically expressed in terms of a single mathematical equation. However, scientific laws are not absolute and can be contradicted, restricted, or extended by future observations.

While scientific laws have never been observed to be violated, they can always be tested for accuracy or applied to new conditions to determine if they hold true or break. Repeatable experimental evidence can invalidate a law or prove that it has limitations. For example, well-established laws have been invalidated in some special cases, leading to new formulations that build upon the original laws. These new formulations are more precise generalizations that account for previously unconsidered conditions, such as very large or very small scales of time or space, extreme speeds, or masses.

The applicability of a scientific law is often limited to specific circumstances resembling those already observed. Extrapolating beyond these circumstances may lead to the discovery that the law is false. For instance, Ohm's law only applies to linear networks, and Newton's law of universal gravitation only holds in weak gravitational fields. Similarly, early aerodynamics laws, like Bernoulli's principle, do not account for compressible flow in transonic and supersonic flight. These laws remain useful but only within their specified domains of application.

Scientific laws are not static and unchanging but rather are subject to refinement and improvement as new evidence and observations come to light. They are empirical conclusions reached through the scientific method and are intended to reflect the causal relationships fundamental to reality. Thus, scientific laws can be contradicted and refined through further scientific inquiry and advancements.

Scientific laws are not the same as scientific theories

Scientific laws and theories are both based on the scientific method, but they are not the same. They differ in scope and function, and each plays a different role in science.

A scientific law is a statement that describes or predicts a range of natural phenomena. It is based on repeated experiments or observations. Laws are developed from data and can be expressed mathematically. They are discovered, not invented, and are not absolute. They are empirical conclusions that can be tested at increased accuracy or in new conditions. They may be invalidated or proven to have limitations by repeatable experimental evidence. Laws are narrow in scope and are not explanations of phenomena. They are distillations of the results of repeated observations. For example, Newton's law of universal gravitation only applies in weak gravitational fields.

A scientific theory, on the other hand, is a verifiable explanation of a natural phenomenon. It can be repeatedly tested and verified using the scientific method and observation. Theories are concise, coherent, systematic, predictive, and broadly applicable. They are not guesses but reliable accounts of how a certain natural phenomenon works. For example, Einstein's Special Relativity explains the relationship between space and time for objects moving at a consistent speed in a straight line.

To summarise, a law predicts what happens, and a theory explains why.

Scientific laws are not the same as facts

Scientific laws are not absolute certainties and are subject to change. They are often formulated as one or several statements or equations that predict the outcome of an experiment. They differ from hypotheses and postulates, which are proposed during the scientific process before validation by experiment and observation. Laws are also narrower in scope than scientific theories, which may entail one or several laws.

On the other hand, facts are observations that have been repeatedly confirmed and are accepted as "true." However, it is important to note that truth in science is never final, and what is accepted as a fact today may be modified or discarded in the future. For example, the fact that "Mercury is liquid at standard temperature and pressure" is considered too specific to qualify as a scientific law.

Furthermore, laws can be invalidated or proven to have limitations by repeatable experimental evidence. Well-established laws have been invalidated in some cases, leading to new formulations that generalize upon the original laws. These new formulations are more precise and account for previously unconsidered conditions.

Therefore, it is clear that scientific laws and facts are distinct concepts in science, serving different purposes and operating at different levels of generality. Laws are based on facts but go beyond them to make predictions and describe the behavior of natural phenomena.

Scientific laws are based on repeated experiments or observations

Scientific laws are developed from data and can be further developed through mathematics. They are directly or indirectly based on empirical evidence. They summarize the results of experiments or observations, usually within a certain range of application. The accuracy of a law does not change when a new theory of the relevant phenomenon is worked out; instead, the scope of the law's application changes, as the mathematics or statement representing the law is altered.

Scientific laws are not absolute certainties and do not posit a mechanism or explanation of phenomena. They are distillations of the results of repeated observation. The applicability of a law is limited to circumstances resembling those already observed, and the law may be found to be false when extrapolated. For example, Ohm's law only applies to linear networks, and Newton's law of universal gravitation only applies in weak gravitational fields. These laws remain useful, but only under the specified conditions where they apply.

Scientific laws are produced from the scientific method through the formation and testing of hypotheses. They can predict the behavior of the natural world and are well-supported by observations and/or experimental evidence. They are descriptive accounts of how nature will behave under certain conditions.
