Universal Pictures (legally Universal City Studios LLC, also known as Universal Studios, and formerly named Universal Film Manufacturing Company and Universal-International Pictures Inc.) is an American film production and distribution company owned by Comcast through the NBCUniversal Film and Entertainment division of NBCUniversal.
Founded in 1912 by Carl Laemmle, Mark Dintenfass, Charles O. Baumann, Adam Kessel, Pat Powers, William Swanson, David Horsley, Robert H. Cochrane, and Jules Brulatour, it is the oldest surviving film studio in the United States; the world's fifth oldest after Gaumont, Pathé, Titanus, and Nordisk Film; and the oldest member of Hollywood's "Big Five" studios in terms of the overall film market. Its studios are located in Universal City, California, and its corporate offices are located in New York City. In 1962, the studio was acquired by MCA, which was re-launched as NBCUniversal in 2004.
Universal Pictures is a member of the Motion Picture Association (MPA), and was one of the "Little Three" majors during Hollywood's golden age.

    Physical meanings of universal coordinates in schwarzschild metric

    The metric due to the gravitational field of a spherical mass is described by the schwarzschild metric ds2 = c2 (1 - R/r) dt2 - (1 - R/r)-1 dr2 - r2 d\Omega 2 Where \Omega is the solid angle, and R is the schwarzschild radius. What are the physical meanings of the coordinates t and r...

    Weight in Vacuum vs Atmosphere: A Question

    not sure if this question has been asked before, but is the weight of an object the same in a vacuum compared to weight in an atmosphere. the concerns of this question is that do we need to consider that our atmosphere provides some boyancy on our mass to change the value of weight.
