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.
Engineers apply the knowledge of math & science to design and manufacture maintainable systems used to solve specific problems. AskEngineers is a forum for questions about the processes and standards used to build these systems, as well as for questions about the engineering profession and its many disciplines.
A subreddit for really great, insightful articles and discussion. Please follow reddiquette, and READ THE ARTICLE before voting or discussing. Downvotes should only be used if something doesn’t contribute to intelligent discussion, not just because you disagree. Please use the report button if you see something that doesn’t belong.
A subreddit to draw simple physics questions away from /r/physics. No real rules; ask away. If your basic physics question isn't answered in a day, you can post it to /r/physics if you mention that you didn't get an answer on /r/AskPhysics (unless it's a homework-related physics question).
