Water Memory
Water memory is the purported ability of water to retain a memory of substances previously dissolved in it even after an arbitrary number of serial dilutions. It has been claimed to be a mechanism by which homeopathic remedies work, even when they are diluted to the point that no molecule of the original substance remains, but there is no theory for it. Water memory is pseudoscientific in nature; it contradicts the scientific understanding of physical chemistry and is generally not accepted by the scientific community. In 1988, Jacques Benveniste and colleagues published a study supporting a water memory effect amid controversy in ''Nature'', accompanied by an editorial by ''Natures'' editor John Maddox urging readers to "suspend judgement" until the results could be replicated. In the years after publication, multiple supervised experiments were made by Benveniste's team, the United States Department of Defense, BBC's ''Horizon'' programme, and other researchers, but no one ...

Water
Water is an inorganic compound with the chemical formula . It is a transparent, tasteless, odorless, and Color of water, nearly colorless chemical substance. It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent). It is vital for all known forms of life, despite not providing food energy or organic micronutrients. Its chemical formula, , indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. In liquid form, is also called "water" at standard temperature and pressure. Because Earth's environment is relatively close to water's triple point, water exists on Earth as a solid, a liquid, and a gas. It forms precipitation in the form of rain and aerosols in the form of fog. Clouds consist of suspended droplets of water and ice, its solid state. When finely divided, crystalline ice ...

Allergic Reaction
Allergies, also known as allergic diseases, are various conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment. These diseases include Allergic rhinitis, hay fever, Food allergy, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis. Symptoms may include allergic conjunctivitis, red eyes, an itchy rash, sneeze, sneezing, coughing, a rhinorrhea, runny nose, shortness of breath, or swelling. Note that food intolerances and food poisoning are separate conditions. Common allergens include pollen and certain foods. Metals and other substances may also cause such problems. Food, insect stings, and medications are common causes of severe reactions. Their development is due to both genetic and environmental factors. The underlying mechanism involves immunoglobulin E antibodies (IgE), part of the body's immune system, binding to an allergen and then to FcεRI, a receptor on mast cells or basophils where it triggers ...

Cold Fusion
Cold fusion is a hypothesized type of nuclear reaction that would occur at, or near, room temperature. It would contrast starkly with the nuclear fusion, "hot" fusion that is known to take place naturally within Main sequence, stars and artificially in Thermonuclear weapon, hydrogen bombs and prototype Fusion power, fusion reactors under immense pressure and at temperatures of millions of degrees, and be distinguished from muon-catalyzed fusion. There is currently no accepted theoretical model that would allow cold fusion to occur. In 1989, two electrochemistry, electrochemists at the University of Utah, Martin Fleischmann and Stanley Pons, reported that their apparatus had produced anomalous heat ("excess heat") of a magnitude they asserted would defy explanation except in terms of nuclear processes. They further reported measuring small amounts of nuclear reaction byproducts, including neutrons and tritium. ("It is inconceivable that this [amount of heat] could be due to anyth ...

After Dark (TV Series)
''After Dark'' was a British late-night live television discussion programme that was broadcast weekly on Channel 4 between 1987 and 1991, and which returned for specials between 1993 and 1997. It was later revived by the BBC for a single series, broadcast on BBC Four in 2003. Roly Keating of the BBC described it as "one of the great television talk formats of all time". In 2010 the television trade magazine ''Broadcast (magazine), Broadcast'' wrote "''After Dark'' defined the first 10 years of Channel 4, just as ''Big Brother (British TV series), Big Brother'' did for the second" and in 2018 the programme was cited in an editorial in ''The Times'' as an example of high-quality television. Broadcast live and with no scheduled end time, the series, inspired by an Austrian programme called ''Club 2'', was considered to be a groundbreaking reinvention of the discussion programme format. The programme was hosted by a variety of presenters, and each episode had around half a do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Observer-expectancy Effect
The observer-expectancy effect is a form of reactivity in which a researcher's cognitive bias causes them to subconsciously influence the participants of an experiment. Confirmation bias can lead to the experimenter interpreting results incorrectly because of the tendency to look for information that conforms to their hypothesis, and overlook information that argues against it. It is a significant threat to a study's internal validity, and is therefore typically controlled using a double-blind experimental design. It may include conscious or unconscious influences on subject behavior including creation of demand characteristics that influence subjects, and altered or selective recording of experimental results themselves. Overview The experimenter may introduce cognitive bias into a study in several in the observer-expectancy effect, the experimenter may subtly communicate their expectations for the outcome of the study to the participants, causing them to alter their be ...

Quirks And Quarks
''Quirks & Quarks'' is a Canadian science news program, heard over CBC Radio One of the Canadian Broadcasting Corporation (CBC). Created by CBC Producer Diana Filer and airing since October 8, 1975, ''Quirks & Quarks'' is consistently rated among the most popular CBC programs, attracting over 800,000 listeners each Saturday from 12:06 to 13:00. The show is also heard on Sirius Satellite Radio and some American public radio stations. The show consists of several segments each week, most of which involve the host interviewing a scientist about a recent discovery or publication, combined with in-depth documentaries; however, from time to time the show does a special "Question Show" episode, during which the format consists of scientists answering questions submitted by listeners. ''Quirks & Quarks'' has offered listeners Internet audio streams and MP3 downloads on its web page since 1993. The MP3 audio files have been archived on the program web site, going back to Sept. 2006. In 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
McCarthyism
McCarthyism is a political practice defined by the political repression and persecution of left-wing individuals and a Fear mongering, campaign spreading fear of communist and Soviet influence on American institutions and of Soviet espionage in the United States during the late 1940s through the 1950s, heavily associated with the Second Red Scare, also known as the McCarthy Era. After the mid-1950s, U.S. senator Joseph McCarthy, who had spearheaded the campaign, gradually lost his public popularity and credibility after several of his accusations were found to be false. The Warren Court, U.S. Supreme Court under Chief Justice Earl Warren made a series of rulings on civil and political rights that overturned several key laws and legislative directives, and helped bring an end to the Second Red Scare. Historians have suggested since the 1980s that as McCarthy's involvement was less central than that of others, a different and more accurate term should be used instead that more acc ...

Double-blind Experiment
In a blind or blinded experiment, information which may influence the participants of the experiment is withheld until after the experiment is complete. Good blinding can reduce or eliminate experimental biases that arise from a participants' expectations, Observer-expectancy effect, observer's effect on the participants, observer bias, confirmation bias, and other sources. A blind can be imposed on any participant of an experiment, including subjects, researchers, technicians, data analysts, and evaluators. In some cases, while blinding would be useful, it is impossible or unethical. For example, it is not possible to blind a patient to their treatment in a physical therapy intervention. A good clinical protocol ensures that blinding is as effective as possible within ethical and practical constraints. During the course of an experiment, a participant becomes #Unblinding, unblinded if they deduce or otherwise obtain information that has been masked to them. For example, a patient w ...
