Decline Effect
The decline effect may occur when scientific claims receive decreasing support over time. The term was first described by parapsychologist Joseph Banks Rhine in the 1930s to describe the disappearing of extrasensory perception (ESP) of psychic experiments conducted by Rhine over the course of study or time. In its more general term, Cronbach, in his review article of science "Beyond the two disciplines of scientific psychology" referred to the phenomenon as "generalizations decay." The term was once again used in a 2010 article by Jonah Lehrer published in ''The New Yorker''. Examples In his article, Lehrer gives several examples where the decline effect is allegedly showing. In the first example, the development of second generation anti-psychotic drugs, reveals that the first tests had demonstrated a dramatic decrease in the subjects' psychiatric symptoms. However, after repeating tests this effect declined and in the end it was not possible to document that these drugs had any ...

Joseph Banks Rhine
Joseph Banks Rhine (September 29, 1895 – February 20, 1980), usually known as J. B. Rhine, was an American botanist who founded parapsychology as a branch of psychology, founding the parapsychology lab at Duke University, the '' Journal of Parapsychology'', the Foundation for Research on the Nature of Man, and the Parapsychological Association. Rhine wrote the books ''Extrasensory Perception'' and '' Parapsychology: Frontier Science of the Mind''. Early life and education Rhine was the second child of five children born to Samuel Ellis Rhine and Elizabeth Vaughan Rhine in Waterloo, Juniata County, Pennsylvania. Samuel Rhine had been educated in a Harrisburg business college, had taught school and later been a farmer and merchant. The family moved to Marshallville, Ohio, when Joseph was in his early teens.Denis, Brian. (1982). ''The Enchanted Voyager''.

Criticism Of Science
Criticism of science addresses problems within science in order to improve science as a whole and its role in society. Criticisms come from philosophy, from social movements like feminism, and from within science itself. The emerging field of metascience seeks to increase the quality of and efficiency of scientific research by improving the scientific process. Philosophical critiques Philosopher of science Paul Feyerabend advanced the idea of epistemological anarchism, which holds that there are no useful and exception-free methodological rules governing the progress of science or the growth of knowledge, and that the idea that science can or should operate according to universal and fixed rules is unrealistic, pernicious and detrimental to science itself. Feyerabend advocates a democratic society where science is treated as an equal to other ideologies or social institutions such as religion, and education, or magic and mythology, and considers the dominance of science ...

Replication Crisis
The replication crisis (also called the replicability crisis and the reproducibility crisis) is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method, such failures undermine the credibility of theories building on them and potentially call into question substantial parts of scientific knowledge. The replication crisis is frequently discussed in relation to psychology and medicine, where considerable efforts have been undertaken to reinvestigate classic results, to determine both their reliability and, if found unreliable, the reasons for the failure. Data strongly indicate that other natural, and social sciences are affected as well. The phrase ''replication crisis'' was coined in the early 2010s as part of a growing awareness of the problem. Considerations of causes and remedies have given rise to a new scientifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hundredth Monkey Effect
The hundredth monkey effect is a hypothetical phenomenon in which a new behavior or idea is spread rapidly by unexplained means from one group to all related groups once a critical number of members of one group exhibit the new behavior or acknowledge the new idea. The behavior was said to propagate even to groups that are physically separated and have no apparent means of communicating with each other.Amundson, Ron. 1985.The Hundredth Monkey Phenomenon" ''Skeptical Inquirer'' 9(4):348–56. Also available vi on May 25, 2011). Since it was first popularized, the effect has been discredited in many cases of research.Michael Shermer, Shermer, Michael. 1997.

Cargo Cult Science
Cargo cult science is a pseudoscientific method of research that favors evidence that confirms an assumed hypothesis. In contrast with the scientific method, there is no vigorous effort to disprove or delimit the hypothesis. The term ''cargo cult science'' was first used by physicist Richard Feynman during his 1974 commencement address at the California Institute of Technology. Cargo cults are religious practices that have appeared in many traditional tribal societies in the wake of interaction with technologically advanced cultures. They focus on obtaining the material wealth (the "cargo") of the advanced culture by imitating the actions they believe cause the appearance of cargo: by building landing strips, mock aircraft, mock radios, and the like. Similarly, although cargo cult sciences employ the trappings of the scientific method, they fail—like an airplane with no motor—to deliver anything of value.

Oil Drop Experiment
The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). The experiment took place in the Ryerson Physical Laboratory at the University of Chicago. Millikan received the Nobel Prize in Physics in 1923. The experiment entailed observing tiny electrically charged droplets of oil located between two parallel metal surfaces, forming the plates of a capacitor. The plates were oriented horizontally, with one plate above the other. A mist of atomized oil drops was introduced through a small hole in the top plate and was ionized by an x-ray, making them negatively charged. First, with zero applied electric field, the velocity of a falling droplet was measured. At terminal velocity, the drag force equals the gravitational force. As both forces depend on the radius in different ways, the radius of the droplet, and therefore the mass and gravitational force, could be determined (usi ...

Harvey Fletcher
Harvey Fletcher (September 11, 1884 – July 23, 1981) was an American physicist. Known as the "father of stereophonic sound", he is credited with the invention of the 2-A audiometer and an early electronic hearing aid. He was an investigator into the nature of speech and hearing, and made contributions in acoustics, electrical engineering, speech, medicine, music, atomic physics, sound pictures, and education. Following his death, he was credited with collaborating with his doctoral advisor, Robert Millikan, on the Nobel-prize winning oil drop experiment which first determined the charge of the electron. Early years Fletcher was born in Provo, Utah. He graduated from Brigham Young High School in 1904. He enrolled at Brigham Young University (BYU), graduating in 1907 with a bachelor's degree. He married Lorena Chipman. They were the parents of seven children. Harvey Fletcher was the father of James C. Fletcher, former president of the University of Utah and NASA Administrat ...

Robert Millikan
Robert Andrews Millikan (March 22, 1868 – December 19, 1953) was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electric charge and for his work on the photoelectric effect. Millikan graduated from Oberlin College in 1891 and obtained his doctorate at Columbia University in 1895. In 1896 he became an assistant at the University of Chicago, where he became a full professor in 1910. In 1909 Millikan began a series of experiments to determine the electric charge carried by a single electron. He began by measuring the course of charged water droplets in an electric field. The results suggested that the charge on the droplets is a multiple of the elementary electric charge, but the experiment was not accurate enough to be convincing. He obtained more precise results in 1910 with his famous oil-drop experiment in which he replaced water (which tended to evaporate too quickly) with oil. In 1914 Millikan t ...

Commencement Speech
A commencement speech or commencement address is a speech given to graduating students, generally at a university, although the term is also used for secondary education institutions and in similar institutions around the world. The commencement is a ceremony in which degrees or diplomas are conferred upon graduating students. A commencement speech is typically given by a notable figure in the community or a graduating student. The person giving such a speech is known as a commencement speaker. Very commonly, colleges or universities will invite politicians, important citizens, or other noted speakers to come and address the graduating class. A student speaker may deliver remarks either in lieu or in conjunction with a notable outside figure. Student commencement speakers are often valedictorians or may otherwise be elected by their peers to represent the student body. Despite meaning "beginning", ''commencement'' may be mistaken to mean "ending" due to its association with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Feynman
Richard Phillips Feynman (; May 11, 1918 – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. For contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga. Feynman developed a widely used pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide by the British journal '' Physics World'', he was ranked the seventh-greatest physicist of all time. He assisted in the develop ...
