Welcome to the MODERATED Science Community, created out of need due to other science communities being invaded by spam, trolls, politics, religion, and conspiracy theorists and abandoned by their moderators or have never had moderators at all. The rules are simple: 1. NO POLITICS! NO RELIGION! NONE AS A POST, NONE IN THE COMMENTS! 2. Read this Google+ netiquette guide. It applies to Minds.com too. http://csharpner.com/blog/index.php/google-netiquette/ It will be STRICTLY enforced here. 3. Post ONLY science related content. 4. Be civil to each other. Everyone here loves science, but may differ greatly in many other ways. Don't focus on your differences, focus on what brings you together. 5. Tag me @CSharpner in the comments of a post you think needs to be moderated. What's "science"? Ideas that are testable . If you can't perform a test, it's not science, it's philosophy. However, theoretical physics can be tested with math, if not with physical experimentation. There's a fuzzy line between theoretical science and philosophy. I will not be strict on drawing a line between the two. Feel free to post your own experiments, builds, projects, and extracurricular activities. Feel free to invite others that meet your standards of science lovers. Enjoy!
