ALGOL Y was the name given to a speculated successor for the ALGOL 60 programming language that incorporated some radical features that were rejected for ALGOL 68 and ALGOL X .

It avoided coercion while not making things difficult for programmers. The letter N is short for Nippon , or Japan in Japanese language Japanese .

unreferenced date May 2011 PS algol is an orthogonal persistency orthogonally persistent programming language . PS algol was an extension of the language S algol implemented by the Universities of St Andrews and Edinburgh , Scotland . S algol was designed by Ron Morrison , and extended and by Pete Bailey, Fred Brown, Paul Cockshott , Ken Chisholm and Al Dearle. PS algol was the world s first fully implemented persistent programming language, and had a significant quantity of users both in academia and, notably, in ICL research labs. History PS algol was conceived by chance, when Ron Morrison was on sabbatical at Edinburgh University and met Malcolm Atkinson . Atkinson had been experimenting with persistent programming languages and was struggling to find a coherent model for a persistent Pascal variant. Morrison, whose interest in general purpose programming had led to the development of S algol, a general purpose teaching language, realised that S algol s type system would more easily allow the addition of orthogonal persistence.

In stellar astronomy , the Algol paradox is an apparently paradox ical situation when elements of a binary star seem to evolve in discord with the established theories of stellar evolution . A fundamental feature of these theories is that the rate of Stellar evolution evolution of stars depends on the mass of the star The greater the mass of the star, the faster this evolution, and the more quickly it leaves the main sequence , entering either a subgiant or Giant star giant phase. In the case of Algol and other binary stars we can observe something completely different The less massive star is already a subgiant, and the star with much greater mass is still on the main sequence. Initially, this seems paradoxical as the partner stars of the binary are thought to have formed at approximately the same time and so should have similar ages. Thus the more massive star, rather than the less massive one, should have left the main sequence. The paradox is resolved by the fact that in many binary stars, there can be a flow of material between the two stars, disturbing the normal process of stellar evolution. As the flow progresses, the evolutionary stage of the stars will advance, even as the relative masses change. Eventually, the originally more massive star will reach the next stage in its evolution despite having lost much of its mass to its companion.
