The problem can be approached using either frequentist inference or Bayesian inference, leading to different results. Estimating the population maximum based on a single sample yields divergent results, whereas estimation based on multiple samples is a practical estimation question whose answer is simple (especially in the frequentist setting ...
Hilbert's tenth problem: the problem of deciding whether a Diophantine equation (multivariable polynomial equation) has a solution in integers. Determining whether a given initial point with rational coordinates is periodic, or whether it lies in the basin of attraction of a given open set, in a piecewise-linear iterated map in two dimensions ...
For example, the JREF had dowsers perform a control test, in which the dowser attempts to locate the target substance or object using their dowsing ability, even though the target's location has been revealed to the applicant. Failure to display a 100% success rate in the open test would cause their immediate disqualification.
James Randi (born Randall James Hamilton Zwinge; August 7, 1928 – October 20, 2020) was a Canadian-American stage magician, author, and scientific skeptic who extensively challenged paranormal and pseudoscientific claims. [1]
A randomized algorithm is an algorithm that employs a degree of randomness as part of its logic or procedure. The algorithm typically uses uniformly random bits as an auxiliary input to guide its behavior, in the hope of achieving good performance in the "average case" over all possible choices of random determined by the random bits; thus either the running time, or the output (or both) are ...
The logo of a winged pig was designed for Randi's website by German artist Jutta Degener in 1996. [2] The name "Pigasus" was chosen by Randi from suggestions e-mailed to him. [ 3 ] The term is a portmanteau pun combining the word pig with the mythological Pegasus , a reference to the expression " when pigs fly ".
Combinatorial explosion is sometimes used to justify the intractability of certain problems. [1] [2] Examples of such problems include certain mathematical functions, the analysis of some puzzles and games, and some pathological examples which can be modelled as the Ackermann function.
It then gives a summary of Randi's career as an illusionist, concluding that some people want to be fooled so badly that even when he explains that it was an illusion, they don't believe him. This is followed by an overview of Randi's debunking activities, culminating with the Russian tour for Secrets of the Psychics which showcased all of the ...
