Either you or I got wooshed, cause I thought that was a maths joke, not actually an answer.

A dump stat for STR characters.

You have a right to your opinion, sure. Just as much as he has the right to tell you it's shit. That's his opinion too.

You might be able to create profiles anonymously, but you can't use those services anonymously. They only work if you have other people added as friends or whatever, unlike content aggregators like lemmy or reddit, where you can be as anonymous as you want and still interact with all features of the site.

I think that narrows it down enough. If you can use all features of the platform without personally knowing anyone on it, it's not social media.

Then email is also social media, Google docs is social media, phpBB is social media, Amazon review sections are social media, even Pornhub comment sections are social media, and so on...

If Lemmy fits the criteria, then so does 95% of the internet. Not a very useful definition, in that case.

Always upvote Feynman. Got me through some tough times in undergrad.

Quantum mechanics didn't supersede electromagnetism. Again, they're different things. Electromagnetism is a fundamental interaction. Whereas quantum mechanics describes the mechanics of quantum particles. Whether those particles are affected by electromagnetic forces or not. It's a description of how they behave at quantum scales.

Coulomb's law has nothing to do with quantum mechanics, it's a description of how macroscopic charged particles interact. What the OP should have said to be correct is:

Awesome to see the similarities between: Newton's law of gravitation and Coulomb's law

I don't know where he got quantum mechanics from.

They're different things. The OP means electromagnetism, Coulomb's law has nothing to do with quantum mechanics, it's classical physics.

The relation between them is that they're both forces that scale with the inverse square of the distance between the objects. Any force that scales with the inverse square of distance has pretty much the same general form.

Another similarity is that both are incomplete, first approximations that describe their respective forces. The more complete versions are Maxwell's laws for electromagnetism and General Relativity for gravity.

It's electromagnetism you mean, not quantum mechanics.

The Earth will always be here. We, on the other hand...

It depends on those factors and a few others. You can also pay extra to ensure your electricity comes from all renewable sources. The so-called "Garantias de Origem" (guarantee of origin).
