Exotic probability is a branch of probability theory that deals with probabilities which are outside the normal range of . The most common author of papers on exotic probability theory is Saul Youssef. According to Youssef, the valid possible alternatives for probability values are the real numbers, the complex numbers and the quaternions.
Youssef also cites the work of Richard Feynman, P. A. M. Dirac, Stanley Gudder and S. K. Srinivasan as relevant to exotic probability theories.
Of the application of such theories to quantum mechanics, Bill Jefferys has said: "Such approaches are also not necessary and in my opinion they confuse more than they illuminate."
Famous quotes containing the words exotic and/or probability:
“Anthropology has always struggled with an intense, fascinated repulsion towards its subject.... [The anthropologist] submits himself to the exotic to confirm his own inner alienation as an urban intellectual.”
—Susan Sontag (b. 1933)
“The probability of learning something unusual from a newspaper is far greater than that of experiencing it; in other words, it is in the realm of the abstract that the more important things happen in these times, and it is the unimportant that happens in real life.”
—Robert Musil (1880–1942)
