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.

Edison shocked animals with AC to disprove Tesla, trying to prove that DC is safer. That is fact. However, the article already states in the beginning:

Edison’s link to the death of Topsy the elephant may not be entirely grounded in reality.

As I posted a while back, this is a rumor that comes along often, The killing of Topsy was done by her handlers as they wanted to get rid of her, they could not handle her anymore after an incident with her original handler. The film of the killing was released by Edison films yes, but Topsy was killed a decade after the war of the currents, and Edison wasn't even in charge anymore of the company after the merger with General Electric. He wasn't present during the electrocution of Topsy, did not have any electric business anymore, and again there is no evidence whatsoever that he was involved.

I learned about the killing of Topsy because I am very interested in the life of Nicolai Tesla and his inventions. I dislike Edison because imo he did Tesla wrong, but I learned quickly that the most despicable thing attributed to him is very likely not true.

Topsy was also electrocuted at the request of the ASPCA because otherwise she was going to be hanged and it was seen as more humane, which always seems to get left out.

To clarify, Edison wasn't trying to 'disprove' Tesla, the War of the Currents was Edison vs Westinghouse. Tesla didn't invent AC, he would've learned about that in engineering school, he invented the 3 phase motor, which made AC significantly more practical. Tesla had an argument with one of Edison's managers over pay, not with Edison. Tesla and Edison wrote each other letters later on and generally spoke positively of each other in public.

Tesla's an interesting guy but unfortunately went off the deep end pretty steeply. His 'death ray' was a 'blueprint' he sold to his landlord instead of paying rent and is basically gibberish. Wardenclyffe tower was doomed by not understanding wireless transmission and is basically a Bond villain device. Turning the Ionosphere and Mantel in to halves of a capacitor would both take more energy than humans have ever generated and be really really really bad for anything tall and conductive, which would be basically everything with the energies involved.

Yikes! The .45-70 Government existed and they considered electrocution and hanging?!

This is the first time I've heard of this hypothesis, as I've just generally avoided media talking about the secrets of Tesla's free energy or whatever, but I am very curious how this would work and what such tripple really bad would happen, sounds like a sweet soft sci fi setting.

[–] turmacar@lemmy.world 5 points 2 months ago

Tesla's design [for Wardenclyffe] used a concept of a charged conductive upper layer in the atmosphere, a theory dating back to an 1872 idea for a proposed wireless power system by Mahlon Loomis. Tesla not only believed that he could use this layer as his return path in his electrical conduction system, but that the power flowing through it would make it glow, providing night time lighting for cities and shipping lanes.

It's a very Victorian / Steampunk idea that is also kind of horrifying. It's working off theories of what electricity "is" that we now know aren't accurate, but if you try to scale them to actually working every building and tree and person is now a lightning rod.

Agreed, Tesla is way overvalued. It doesn't help that he gets picked up by free energy cranks. When one shows up at my makerspace, they almost always cite Tesla somewhere.

Not that Tesla did nothing, but people can't leave it at his actual accomplishments. The fact that so much of his work can't be reproduced is seen as deep magic rather than a failure of science.
