The aim of /r/Physics is to build a subreddit frequented by physicists, scientists, and those with a passion for physics. Papers from physics journals (free or otherwise) are encouraged. Posts should be pertinent, meme-free, and generate a discussion about physics. Please report trolls and intentionally misleading comments.
/r/NASA is for anything related to the National Aeronautics and Space Administration; the latest news, events, current mission and future missions and more.
>Note: r/nasa is an unofficial forum and not representative of NASA or the US government
Engineers apply the knowledge of science and math to build maintainable systems and devices to solve problems. AskEngineers is a forum for questions about the processes and standards used to build them, as well as for questions about the engineering profession and its many disciplines.
