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.

Are you suggesting that this isn't a real photograph of 12th century Bologna??

Here are real images. Tell me how you can safely demolish those with explosives while guaranteeing it's not going to topple over adjacent buildings.

I'm sure the construction of towers is different from chimney stacks, but Fred Dibnah did it with a bunch of firewood and some shovels.

Do you see a direction without buildings there so it can topple over safely? That's the main issue.

These towers are significantly different from a mud brick stack, too. The fact that they're square is important. They're also built with different materials: instead of a lattice of uniform bricks and mortar, they are built with two layers of masonry filled with assorted stones and mortar. Not the kind of building we're used to demolish, making it harder to predict.

demolish the adjacent buildings first

[–] acockworkorange@mander.xyz 3 points 1 day ago (1 children)

Use the tower and demolish them all in one fell swoop! Demolitionists hate this one trick!

one big explosion is less fun than a lot of little explosions and one big explosion

[–] Lojcs@piefed.social 1 points 1 day ago (1 children)

I don't know? But it's definitely easier than what the picture in the post suggests

[–] acockworkorange@mander.xyz -1 points 1 day ago (1 children)

Maybe just stick to the first sentence.

[–] Lojcs@piefed.social 0 points 1 day ago

? Demolishing 2 detached towers is definitely easier than 50 built directly on buildings.

[–] starlinguk@lemmy.world 1 points 1 day ago

Towers like this still exist in places like San Gimignano.
