The Encyclopedia of Pseudoscience is the first one-volume, A-to-Z reference that identifies, defines, and explains all of the terms and ideas dealing with the somewhat murky world of the "almost sciences". Truly interdisciplinary and multicultural in scope, the Encyclopedia examines how fringe or marginal sciences have affected people throughout history, as well as how they continue to exert an influence on our lives today. This comprehensive reference brings together: superstitions and fads that are part of popular culture, such as fortune telling; healing practices once thought marginal that are now become increasingly accepted, such as homeopathy and acupuncture; frauds and hoaxes that have occurred throughout history, such as UFOs; mistaken theories first put forward as serious science, but later discarded as false, such as phrenology and racial typing, etc. More than 2000 extensively cross-referenced and illustrated entries cover prominent phenomena, major figures, events topics, places and associations.
