Rules:

1. Be civil

Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.

2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.

Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.

3. No bots, spam or self-promotion.

Only approved bots, which follow the guidelines for bots set by the instance, are allowed.

4. Post titles should be the same as the article used as source. Clickbait titles may be removed.

Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.

5. Only recent news is allowed.

Posts must be news from the most recent 30 days.

6. All posts must be news articles.

No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.

7. No duplicate posts.

If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.

8. Misinformation is prohibited.

Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.

9. No link shorteners or news aggregators.

All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link.

Pythagorean Theorem Found On Clay Tablet 1,000 Years Older Than Pythagoras (www.iflscience.com)

Study math for long enough and you will likely have cursed Pythagoras's name, or said "praise be to Pythagoras" if you're a bit of a fan of triangles.

But while Pythagoras was an important historical figure in the development of mathematics, he did not figure out the equation most associated with him (a2 + b2 = c2). In fact, there is an ancient Babylonian tablet (by the catchy name of IM 67118) which uses the Pythagorean theorem to solve the length of a diagonal inside a rectangle. The tablet, likely used for teaching, dates from 1770 BCE – centuries before Pythagoras was born in around 570 BCE.

I searched in my app for Pythagoras and I didn't see it posted. I wouldn't have posted it if I had known it had been posted two days ago. In the grand scheme of things it isn't that horrible a transgression.

I don't blame you. Here's the one from 2 days ago. (New to lemmy. I'm guessing there's a better way to link posts, but I don't know it.)

As you can see, the only way you'd be likely to find it is if you searched for "trigonometry" or "babylonian". That's why it's so important to have the most specific keywords in the post, for searching. "Babylonian" and "trigonometry" are really good for this, but it feels like "Pythagoras" or "Pythagorean" is essential.

I actually remember seeing that article but I didn't click on it. Oh well. I really want lemmy to survive. I used to love Google+ and it was sad to see it die a slow death. For a while it was, in my opinion, the best photography community on the web. I figure if people see the same content over as over again they'll just leave. So I'm trying to post frequently but not just pure crap.

The paper this article is based on is from 2009. I'd argue that's against rule 5.
