Ask Lemmy
A Fediverse community for open-ended, thought provoking questions
Rules: (interactive)
1) Be nice and; have fun
Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them
2) All posts must end with a '?'
This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?
3) No spam
Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.
4) NSFW is okay, within reason
Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com.
NSFW comments should be restricted to posts tagged [NSFW].
5) This is not a support community.
It is not a place for 'how do I?', type questions.
If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.
6) No US Politics.
Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world
7) No Hit-and-Run questions.
Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.
Reminder: The terms of service apply here too.

What they teach: humans only have five senses (touch, smell, etc) What is true: humans have ~20-30 senses (including time, balance, and many more)
5 senses
4 states of matter
fossil fuel (oil is made from dead dinosaurs)
the American Dream
China is evil
Communism is bad
We were taught 5 states (solid/liquid/gas/plasma/condensate (BEC and superconductors)), which has always felt like a decent enough explanation for 3rd graders. If you barely understand how to read a phase change diagram, you don't really need the confusing duality of being told "hey so this is totally wrong if you're a chemist, but fundementally true if you're an engineer" when you're still iffy on concepts like "vacuum boiling is not witchcraft".
I'm clearly a bit older (prior to plasma categorized) and was taught 4.
Huh, that's really interesting. I'd have expected it was prior to condensate being introduced, not plasma, since plasma can be easily demonstrated in the classroom but condensates have really only been easily demonstrable for at most two decades. Very curious - do you remember if you had a standardized curriculum, and if so which one it was?
I also found it weird, I was taught 3 in school, but Plasma was already being considered a different state, just wasn't taught in schools. Condensate had only just been experimentally created and I didn't even knew about them until this thread.
Honestly I think it was just three now that you mention it and the other reply. Have no clue the curriculum, it was in the 70s.
