Today I Learned
What did you learn today? Share it with us!
We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.
Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

And just like that, 1 in every seven kids in the world got royally fucked.
Right?
Let's see, Pythagorean theorem, is what, a couple thousand years old, and a single statement, right? And it's the foundation of geometry and trig. Hell, I regularly say it in my head (a2+b2=c2) when trying to figure out spatial relationships, for dumb stuff no less (will this table fit on my patio with room to walk around it?).
It's how you ensure anything you're trying to make square is square. In framing (shed, house, deck, whatever) it's used to ensure you setup your string in the proper orientation and don't end up with a parallelogram.
And the Periodic table.... The bloody basis of understanding chemical reactions and physics.
I guess if you're not teaching the Periodic Table, there'd be no hope if understanding evolutionary theory, since it's predicated on chemical behaviour.
Just for clarification, so less people use it wrong:
a² + b² = c² (a*a + b*b = c*c) is the Pythagorean Theorem.
a2 + b2 = c2 would be a+a + b+b = c+c.
when i’m away from my computer’s compose key, i put the exponent after a term to do it in plain text, and would write the latter as 2a+2b=2c.
