Review Definition and 477 Threads

A review is an evaluation of a publication, service, or company such as a movie (a movie review), video game (video game review), musical composition (music review of a composition or recording), book (book review); a piece of hardware like a car, home appliance, or computer; or softwares such as business software, sales softwares; or an event or performance, such as a live music concert, play, musical theater show, dance show or art exhibition. In addition to a critical evaluation, the review's author may assign the work a rating to indicate its relative merit. More loosely, an author may review current events, trends, or items in the news. A compilation of reviews may itself be called a review. The New York Review of Books, for instance, is a collection of essays on literature, culture, and current affairs. National Review, founded by William F. Buckley Jr., is an influential conservative magazine, and Monthly Review is a long-running socialist periodical.

    Is My Peer Review Taking Longer Than Usual?

    I sent a paper in for peer review to the journal "General Relativity and Gravitation" 30/10 2011. On 12/11 2011 they sent it out for peer review. Then 5/12 2011 they sent it out for peer review again, obviously one of the referees could not make up his mind or something so they sent it to a...

    Proving f is a Polynomial with Degree at Most n in Complex Analysis

    Let D ⊂ ℂ be a domain and let f be analytic on D. Show that if there is an a ∈ D such that the kth derivative of f at a is zero for k=n, n+1, n+2,..., then f is a polynomial with degree at most n. So I believe I have a proof, but the theorems are so powerful I feel like I might be...

    Can Penrose's Cyclic Universe Theory Outshine Inflation Theory?

    Local superdeterministic hidden variables - in Physical Review Letters

    It is an old idea that, at least in principle, hidden variables could be local if they are superdeterministic. However, so far this idea seemed too speculative for highly respectable journals such as Physical Review Letters to publish research on it. But now it seems that it has changed. The...
