Superseded Scientific Theories
This list includes well-known general theories in science and pre-scientific natural philosophy and natural history that have since been superseded by other scientific theories. Many discarded explanations were once supported by a scientific consensus, but replaced after more empirical information became available that identified flaws and prompted new theories which better explain the available data. Pre-modern explanations originated before the scientific method, with varying degrees of empirical support. Some scientific theories are discarded in their entirety, such as the replacement of the phlogiston theory by energy and thermodynamics. Some theories known to be incomplete or in some ways incorrect are still used. For example, Newtonian classical mechanics is accurate enough for practical calculations at everyday distances and velocities, and it is still taught in schools. The more complicated relativistic mechanics must be used for long distances and velocities nearing t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malaria
Malaria is a Mosquito-borne disease, mosquito-borne infectious disease that affects vertebrates and ''Anopheles'' mosquitoes. Human malaria causes Signs and symptoms, symptoms that typically include fever, Fatigue (medical), fatigue, vomiting, and headaches. In severe cases, it can cause jaundice, Epileptic seizure, seizures, coma, or death. Symptoms usually begin 10 to 15 days after being bitten by an infected ''Anopheles'' mosquito. If not properly treated, people may have recurrences of the disease months later. In those who have recently survived an infection, reinfection usually causes milder symptoms. This partial Immunity (medical), resistance disappears over months to years if the person has no continuing exposure to malaria. The mosquitoes themselves are harmed by malaria, causing reduced lifespans in those infected by it. Malaria is caused by protozoa, single-celled microorganisms of the genus ''Plasmodium''. It is spread exclusively through bites of infected female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protoscience
In the philosophy of science, protoscience is a research field that has the characteristics of an undeveloped science that may ultimately develop into an established science. Philosophers use protoscience to understand the history of science and distinguish protoscience from science and pseudoscience. The word "protoscience" is a hybrid Greek-Latin compound of the roots '' proto-'' + '' scientia'', meaning a first or primeval rational knowledge. Examples of protoscience include alchemy, Wegener's original theory of continental drift and political economy (the predecessor to the modern economic sciences). History Protoscience as a research field with the characteristics of an undeveloped science appeared in the early 20th century. In 1910, Jones described the field of political economy as it began the transition to the modern field of economics: : I confess to a personal predilection for some term such as proto-science, pre-science, or nas-science, to give expression to what I ...

Scientific Community
The scientific community is a diverse network of interacting scientists. It includes many "working group, sub-communities" working on particular scientific fields, and within particular institutions; interdisciplinary and cross-institutional activities are also significant. Objectivity (philosophy), Objectivity is expected to be achieved by the scientific method. Peer review, through discussion and debate within journals and conferences, assists in this objectivity by maintaining the quality of research methodology and interpretation of results. History of scientific communities The eighteenth century had some societies made up of men who studied nature, also known as natural philosophy, natural philosophers and natural history, natural historians, which included even amateurs. As such these societies were more like local clubs and groups with diverse interests than actual scientific communities, which usually had interests on specialized disciplines. Though there were a few olde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fringe Science
Fringe science refers to ideas whose attributes include being highly speculative or relying on premises already Objection (argument), refuted. The chance of ideas rejected by editors and published outside the mainstream being correct is remote. When the general public does not distinguish between science and imitators, it risks exploitation, and in some cases, a "yearning to believe or a generalized suspicion of experts is a very potent incentive to accepting some pseudoscientific claims". The term "fringe science" covers everything from novel hypotheses, which can be tested utilizing the scientific method, to wild ad hoc hypotheses and Mumbo jumbo (phrase), mumbo jumbo. This has resulted in a tendency to dismiss all fringe science as the domain of Pseudoscience, pseudoscientists, hobbyists, and Quackery, quacks. A concept that was once accepted by the mainstream scientific community may become fringe science because of a later evaluation of previous research. For example, focal i ...

Theodore Schick
Theodore Schick is an American author in the field of philosophy. His articles have appeared in numerous publications and include topics such as functionalism and its effect on immortality, the logic behind the criteria of adequacy, and applying a scientific approach to the paranormal. In 1994, Schick and Lewis Vaughn published ''How to Think About Weird Things: Critical Thinking for a New Age'', which is designed to teach the reader how to think critically about extraordinary claims. Schick and Vaughn say the adequacy of scientific hypotheses depends on their testability, fruitfulness, scope, simplicity, and conservatism. Biography He received a B.A. from Harvard University and a Ph.D. in philosophy from Brown University. Currently, he is a professor of philosophy at Muhlenberg College and the director of the Muhlenberg Scholars program. His upper-level courses include the philosophy of mind, biomedical ethics, and the philosophy of science. He plays lead guitar in the band D ...

Karl Popper
Sir Karl Raimund Popper (28 July 1902 – 17 September 1994) was an Austrian–British philosopher, academic and social commentator. One of the 20th century's most influential philosophers of science, Popper is known for his rejection of the classical inductivist views on the scientific method in favour of Falsifiability, empirical falsification, and for founding the Department of Philosophy at the London School of Economics. According to Popper, a theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can (and should) be scrutinised with decisive experiments. Popper was opposed to the classical Justification (epistemology), justificationist account of knowledge, which he replaced with "the first non-justificational philosophy of criticism in the history of philosophy", namely critical rationalism. In political discourse, he is known for his vigorous defence of liberal democracy and the principles of social criticism that he believed mad ...

Prediction
A prediction (Latin ''præ-'', "before," and ''dictum'', "something said") or forecast is a statement about a future event or about future data. Predictions are often, but not always, based upon experience or knowledge of forecasters. There is no universal agreement about the exact difference between "prediction" and " estimation"; different authors and disciplines ascribe different connotations. Future events are necessarily uncertain, so guaranteed accurate information about the future is impossible. Prediction can be useful to assist in making plans about possible developments. Opinion In a non-statistical sense, the term "prediction" is often used to refer to an informed guess or opinion. A prediction of this kind might be informed by a predicting person's abductive reasoning, inductive reasoning, deductive reasoning, and experience; and may be useful—if the predicting person is a knowledgeable person in the field. The Delphi method is a technique for elicitin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falsifiability
Falsifiability (or refutability) is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the Philosophy of science, philosopher of science Karl Popper in his book ''The Logic of Scientific Discovery'' (1934). A Scientific theory, theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test. Popper emphasized the asymmetry created by the relation of a universal law with basic observation statements and contrasted falsifiability to the intuitively similar concept of Verifiability (science), ''verifiability'' that was then current in logical positivism. He argued that the only way to verify a claim such as "All swans are white" would be if one could theoretically observe all swans, which is not possible. On the other hand, the falsifiability requirement for an anomalous instance, such as the observation of a single black swan, is theoretically reasonable and sufficient to logically falsify the claim. Popper propo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Testability
Testability is a primary aspect of science and the scientific method. There are two components to testability: #Falsifiability or defeasibility, which means that counterexamples to the hypothesis are logically possible. #The practical feasibility of observing a reproducible series of such counterexamples if they do exist. In short, a hypothesis is testable if there is a possibility of deciding whether it is true or false based on experimentation by anyone. This allows anyone to decide whether a theory can be supported or refuted by data. However, the interpretation of experimental data may be also inconclusive or uncertain. Karl Popper introduced the concept that scientific knowledge had the property of falsifiability as published in '' The Logic of Scientific Discovery''.Karl Popper "The Logic of Scientific Discovery", 1934 (as ''Logik der Forschung'', English translation 1959), ISBN 0415278449 and 2002 ISBN 9780415278447, 0415278449 See also * Confirmability * Controlla ...

Pseudoscience
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to evaluation by other experts; absence of systematic practices when developing hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. It is not the same as junk science. The demarcation between science and pseudoscience has scientific, philosophical, and political implications. Philosophers debate the nature of science and the general criteria for drawing the line between scientific theories and pseudoscientific beliefs, but there is widespread agreement "that creationism, astrology, homeopathy, Kirlian photography, dowsing, ufology, ancient astronaut theory, Holocaust den ...
