Isolation (illusion) important developments was the combination of crystal ball isolations and body-popping/locking/waving dance styles, as seen in the styles of, amongst others, Nik Robson and Matt Hennem in the '90s. Isolation (illusion) In contact juggling, poi spinning, hooping and other types of object manipulation, an isolation is an illusion whereby a prop appears to float in space, with the performer's hands and body moving around it. In reality the performer is supporting the prop, and countering his or her movement relative to the prop. Michael Moschen is originally credited for developing several of the techniques for ball isolations (as well as
Isolation lemma Isolation lemma In theoretical computer science, the term isolation lemma (or isolating lemma) refers to randomized algorithms that reduce the number of solutions to a problem to one, should a solution exist. This is achieved by constructing random constraints such that, with non-negligible probability, exactly one solution satisfies these additional constraints if the solution space is not empty. Isolation lemmas have important applications in computer science, such as the Valiant–Vazirani theorem and Toda's theorem in computational complexity theory. The first isolation lemma was introduced by , albeit not under that name. Their isolation lemma chooses a random number of random
