Hypothesis

A hypothesis (plural hypotheses) is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used synonymously, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research.

A different meaning of the term hypothesis is used in formal logic, to denote the antecedent of a proposition; thus in the proposition "If P, then Q", P denotes the hypothesis (or antecedent); Q can be called a consequent. P is the assumption in a (possibly counterfactual) What If question.

The adjective hypothetical, meaning "having the nature of a hypothesis", or "being assumed to exist as an immediate consequence of a hypothesis", can refer to any of these meanings of the term "hypothesis".

Hypothesis (album)

Hypothesis is a 1978 album by the Greek artist Vangelis. In May 1971 Vangelis had played several sessions in London's Marquee Studios, joined for some of them by violinist Michel Ripoche, bass guitarist Brian Odgers (called Odger on the sleeve) and drummer Tony Oxley, the rhythm section of the famous Extrapolation recording released by John McLaughlin. Two albums' worth of material had resulted from these sessions, but were unfinished and never intended for release. Nevertheless, in 1978 two albums duly appeared in shops, on the Affinity label (a subsidiary of Charly Records) Hypothesis and The Dragon. Vangelis subsequently took the label to court to have both LPs taken off the market. Hypothesis has critically been considered to be unsuccessful as an album.

Musically, the album can be considered to be Vangelis' most idiosyncratic and unusual release, as it takes the form of an extended experiment in experimental Jazz, or Jazz fusion.

An alternative release of Hypothesis was titled Visions of the Future.
