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.

Source : « The Great Scientists: From Euclid to Stephen Hawking », from John Farndon

I.d.k. why i thought that Euclid, and perhaps also others, were around Plato or before, just wanted to share, what a time.

B.t.w., we know about ChatGPT, some about Sam Altman, but nothing about the researchers, and the same goes for every other technology, it's a choice of society 🤷(, causes&consequences).

Edit : Transcript :

All the same, if anyone wanted a proper education, Alexandria in Egypt was the place to go, and here Archimedes went as a young man.
At the time he was there, the city was the greatest centre of learning in the ancient world. Although the museum or university there was barely 20 years old – the city itself had been founded by Alexander the Great just half a century earlier – it already held an unrivalled library, containing at least 100,000 scrolls, including all of Aristotle’s priceless personal collection.
It was here that the great Euclid taught geometry, that Aristarchus showed that the Earth revolved around the Sun, and that Hipparchus made the first great catalogue of constellations, categorizing stars in terms of their brightness. And it was here that, much later, Ptolemy wrote the Almagest, the most influential book about the nature of the universe for 1,500 years.
Euclid was probably dead by the time Archimedes was there, but Archimedes undoubtedly met Eratosthenes, the brilliant thinker who measured the circumference of the world to within 4 per cent of modern figures, and made a measurement of the year’s length as precise as any until barely half a century ago.

Edit : Now that i think about it, conquering Persia&Egypt&.. probably helped them in developing these knowledges/sciences

What a weird rule, do you know why it exists ?

What a weird rule, do you know why it exists ?

Accessibility. A blind person (or someone who just can't see that well, or who wants to read it at a different font and sizing level) has the opportunity to read this in text form with a screen reader or with adjusted view settings. But those don't work with images (screen readers may if the image has alt text).

Ease of search. If someone wanted to find this post down the line, they are not able to search the actual text of the post because it's an image.

Quality. In all honesty, what is gained by this post being an image instead of text? What is the visual element adding that couldn't be accomplished with italics and bolding?

What should i have done to post this information then ?

Copy it and treat it as a quote in your written post (same place you put your source). You can add formatting to it if you want to emphasize parts.

I personally prefer a picture because most softwares for browsing Lemmy require to load the whole post in order to read the selftext, but agree with your arguments/explanations, so if that ever happens again i'll try not to forget to accompany the picture with a transcript.
Thank you very much for such an answer/explanation.
