mathematical and experimental techniques employed in the natural sciences; more specifically, techniques used in the construction and testing of scientific hypotheses

The scientific method refers to ways to get facts, correct errors and mistakes, and test theories. The Oxford English Dictionary says that scientific method is: "a method or procedure that has characterized natural science since the 17th century". It is observation, measurement, and experiment, plus the formulation, testing, and modification of hypotheses. A scientist gathers empirical and measurable evidence, and uses sound reasoning. New knowledge often needs adjusting, or fitting into, previous knowledge. Criterion What distinguishes a scientific method of inquiry is a question known as the criterion'. It is an answer to the question: is there a way to tell whether a concept or theory is science, as opposed to some other kind of knowledge or belief? There have been many ideas as to how it should be expressed. Logical positivists thought a theory was scientific if it could be verified (proved true). Karl Popper thought this was a mistake. He thought a theory was not scientific unless there was some way it might be refuted (shown to be wrong). On the other hand, Paul Feyerabend thought...

Since the discovery of electroencephalography to measure brain activity in 1924, sleep research has rapidly advanced. Contemporary sleep research no longer focuses on the length of sleep and the consequences of sleep loss. Instead, a multitude of sleep parameters, such as sleep duration, quality, irregularity, health, and disordered sleep, now inform the sleep science community about the importance of sleep in relation to health, performance, cognitive, cultural, and clinical outcomes through diverse study designs, equipment, and across a range of populations. This special issue on sleep and its disorders has shown us how diverse and widespread the study of sleep has become today. Geographically, it is remarkable that we received manuscripts from various continents and from dozens of countries. The themes and approaches were equally diverse, ranging from population-based studies to laboratory investigations, and including discussions of public policies related to sleep.
