1. Relevant commentary on your own dull life.
Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull.
If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying
No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting.
Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

Before you people are scared to use a MRI now: I can not imagine that they don't have multiple safeties in place to avoid explosion. I've never worked on cryo stuff, but from regularly cooled big machines, there are always redundant measures to avoid the big boom, and where there aren't, you can identify them by the scary sign and the heavy breathing of the safety officer. And that is for internal stuff, patient/customer facing things are probably treated even more carefully
Oh yeah, sorry, didn't mean to scare people! Even if it catastrophically explodes, there's zero chance anything can happen to you. There's so much stuff between you and the magnet that even the worst case will just damage the machine.
In the event of a quench, there's no explosion. Just a venting of the (now) gaseous helium. Still don't want to be in it during, not no actual explosion.
