TelepathyTelepathy () is the purported vicarious transmission of information from one person's mind to another's without using any known human sensory channels or physical interaction. The term was first coined in 1882 by the classical scholar Frederic W. H. Myers, a founder of the Society for Psychical Research (SPR), and has remained more popular than the earlier expression thought-transference. Telepath experiments have historically been criticized for a lack of proper controls and repeatability.
Alice's Adventures in WonderlandAlice's Adventures in Wonderland (commonly Alice in Wonderland) is an 1865 English children's novel by Lewis Carroll, a mathematics don at Oxford University. It details the story of a young girl named Alice who falls through a rabbit hole into a fantasy world of anthropomorphic creatures. It is seen as an example of the literary nonsense genre. The artist John Tenniel provided 42 wood-engraved illustrations for the book.
DowsingDowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, claimed radiations (radiesthesia), gravesites, malign "earth vibrations" and many other objects and materials without the use of a scientific apparatus. It is also known as divining (especially in water divining), doodlebugging (particularly in the United States, in searching for petroleum or treasure) or (when searching for water) water finding, or water witching (in the United States).
Richard K. GuyRichard Kenneth Guy (30 September 1916 – 9 March 2020) was a British mathematician. He was a professor in the Department of Mathematics at the University of Calgary. He is known for his work in number theory, geometry, recreational mathematics, combinatorics, and graph theory. He is best known for co-authorship (with John Conway and Elwyn Berlekamp) of Winning Ways for your Mathematical Plays and authorship of Unsolved Problems in Number Theory. He published more than 300 scholarly articles.
Roger PenroseSir Roger Penrose (born 8 August 1931) is a British mathematician, mathematical physicist, philosopher of science and Nobel Laureate in Physics. He is Emeritus Rouse Ball Professor of Mathematics in the University of Oxford, an emeritus fellow of Wadham College, Oxford, and an honorary fellow of St John's College, Cambridge, and University College London. Penrose has contributed to the mathematical physics of general relativity and cosmology.
Mathematical puzzleMathematical puzzles make up an integral part of recreational mathematics. They have specific rules, but they do not usually involve competition between two or more players. Instead, to solve such a puzzle, the solver must find a solution that satisfies the given conditions. Mathematical puzzles require mathematics to solve them. Logic puzzles are a common type of mathematical puzzle. Conway's Game of Life and fractals, as two examples, may also be considered mathematical puzzles even though the solver interacts with them only at the beginning by providing a set of initial conditions.
PsionicsIn American science fiction of the 1950s and '60s, psionics was a proposed discipline that applied principles of engineering (especially electronics) to the study (and employment) of paranormal or psychic phenomena, such as extrasensory perception, telepathy and psychokinesis. The term is a portmanteau formed from psi (in the sense of "psychic phenomena") and the - from electronics. The word "psionics" began as, and always remained, a term of art within the science fiction community and—despite the promotional efforts of editor John W.
AmbigramAn ambigram is a calligraphic or typographic design with multiple interpretations as written words. Alternative meanings are often yielded when the design is transformed or the observer moves, but they can also result from a shift in mental perspective. The term was coined by Douglas Hofstadter in 1983–1984. Most often, ambigrams appear as visually symmetrical words. When flipped, they remain unchanged, or they mutate to reveal another meaning.
