Application Definition and 998 Threads

An application program (app or application for short) is a computer program designed to carry out a specific task other than one relating to the operation of the computer itself, typically to be used by end-users. Examples of an application include a word processor and a media player. The collective noun refers to all applications collectively. The other principal classifications of software are system software, relating to the operation of the computer, and utility software ("utilities").
Applications may be bundled with the computer and its system software or published separately and may be coded as proprietary, open-source, or projects. Apps built for mobile platforms are called mobile apps.

    Statement of Purpose for physics grad application

    Hi, I'm sorry if this has been discussed at great length before here (I did do a search before hand for Statement of Purpose but didn't find too much, forgive me if I've missed a thread). I'm from the UK and about to start putting my applications to US gradschools, from what I've gleaned...

    Will someone check my application of kepler's laws?

    1. The period of the Earth's orbit is approximately 365.25 days. Use this fact and Kepler's Third Law to find the length of the major (not semi-major) axis of the Earth's orbit. You will need the mass of the sun, M = 1.99x10^30 kg, and the gravitational constant, G = 6.67x10^-11 Nm^2/kg^2...
