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.

It's amazing to put into perspective how long both bronze and stone ages really took, especially compared to modernity. Human brains are not good at imagining large quantities or intervals, so it was all kinda smushed up into a folder labeled "past" in my head
Kurzgesagt did this video where they crammed all of Earth's history in an hour. Basically you look at a barren wasteland for most of the time until life finally goes macroscopic and then all of humanity happens in less than a second
I sat through the whole thing and it's still incomprehensible
It's gotten so fast that we now see significant changes in our lifetimes - cultural, technology, climate. For most of human history, it took many generations for any real change to occur.
Japan might be the record holder for fastest significant change, though. Feudalism to a modern industrial economy in a few decades.
Please. The USSR industrialization speed run is unsurpassed. Peasants to the first artificial satellite in 40 years. Also, parts of Russia are still completely undeveloped today!
Japan did it twice. They closed their borders between bouts of rapid modernizations.
