Scientific laws or laws of science are statements, based on repeated experiments or observations, that describe or predict a range of natural phenomena. [1] The term law has diverse usage in many cases (approximate, accurate, broad, or narrow) across all fields of natural science (physics, chemistry, astronomy, geoscience, biology).
Rather than depend on provability of these axioms, science depends on the fact that they have not been objectively falsified. Occam's razor and parsimony support, but do not prove, these axioms of science. The general principle of science is that theories (or models) of natural law must be consistent with repeatable experimental observations.
Hick's law, in psychology, describes the time it takes for a person to make a decision as a function of the number of possible choices. Hickam's dictum , in medicine , is commonly stated as "Patients can have as many diseases as they damn well please" and is a counterargument to the use of Occam's razor .
In jurisprudence, "legal positivism" essentially refers to the rejection of natural law; thus its common meaning with philosophical positivism is somewhat attenuated and in recent generations generally emphasizes the authority of human political structures as opposed to a "scientific" view of law.
The Weber–Fechner laws are two related scientific laws in the field of psychophysics, known as Weber's law and Fechner's law. Both relate to human perception, more specifically the relation between the actual change in a physical stimulus and the perceived change. This includes stimuli to all senses: vision, hearing, taste, touch, and smell.
Applied psychology is the use of psychological methods and findings of scientific psychology to solve practical problems of human and animal behavior and experience. . Educational and organizational psychology, business management, law, health, product design, ergonomics, behavioural psychology, psychology of motivation, psychoanalysis, neuropsychology, psychiatry and mental health are just a ...
A scientific theory differs from a scientific fact or scientific law in that a theory seeks to explain "why" or "how", whereas a fact is a simple, basic observation and a law is an empirical description of a relationship between facts and/or other laws.
The law is falsifiable and much more useful from a scientific point of view, if the method to detect the neutrino is specified. [42] Maxwell said that most scientific laws are metaphysical statements of this kind, [43] which, Popper said, need to be made more precise before they can be indirectly corroborated.
