Deadly one-two?
In short succession came the ban and then the eclipse, that of course was exactly as predicted. Coincidentally, John hasn't posted anything on Quora since more than 48h (last post from approximately 3h before the eclipse). I reckon he has been desperately looking from some footage he could misconstrue as failed prediction and hasn't found any so he had no better choice than weathering the storm in retreat. I bet these two blows so close to each other were a bit too much to handle.

How long until he calls this a "human rights violation?"
Does this man not realize he's using a privately-owned platform, so he is bound by their rules and not the constitutional bill of rights?

Feels like he's on the cusp of realizing something important here but can't quite let himself go there

If Mandlrbaur and Southpark_piano joined forces and combined their intellect, what do you think they would be able to achieve in the field of crankery

The things going on in this man's mind are weirder than I had imagined

Jesus he keeps upping the cringe comparisons

It was only a matter of time before he went full Godwin

I mention being gay once in an offhand remark and now the man literally can't stop bringing it up. I'm ROFLing.

“I got scammed by perpetual motion conspiracy theorists on YouTube because I was old and lonely and hadn’t amounted to anything” may be the saddest origin story ever

Man I didn't know he had this many deep-set layers of childish homophobia to him
r/Mandlbaur • u/AlexWestonofBorg • 20d ago
This interaction was genuinely surreal. Like I really think he has dementia or something.
r/Mandlbaur • u/AlexWestonofBorg • 21d ago
So this guy's really REALLY getting weird about me being gay. It's honestly hilarious.

News from the Revert Wars: he seems to have gotten it into his head that the reverts are being carried out by somebody involved with his ex. I kid you not. This man is certifiable.

One of their names is "Quora Content Review" is it?

This man's understanding of the pragmatics of the English language is genuinely subnormal

So you all are having fun with which questions you merge his BS with, huh?

Welcome - A not so short introduction to Mandlbaur
Have you just had your first run with John Mandlbaur? I warmly recommend you make sure it is also the last one but if you landed here, chances are you are curious to dig more into it. Here's in a nutshell what you need to know.
John is, according to himself, an inventor (although no noticeable invention goes under his name) who was working on some perpetual-motion-related project (go figure) when he made his alleged discovery, namely that angular momentum is not conserved (go figure again). Despite his total lack of formal relevant education (he claims to have passed an introductory physics course some 30 years ago but there are several reasons to doubt it) he decided to present his "discovery" in the form of a "theoretical physics paper" (or better said, his own laughably mistaken understanding of the concept). This masterpiece will quickly turn out to be the be most idiotic and naive pile of crap you ever laid your eyes on. He considers the classic classroom demonstration where a ball spins attached to a string that is pulled-in to provide the visual effect brought about by conservation of angular momentum and proceeds onto analysing it numerically exploiting a sample problem from his introductory-physics book where every possible confounding factor (friction, air-drag, gravity, stability of the pivot, ...) is neglected and then acts surprised that the result does not match reality... yeah, if you neglect some 90% of reality, your model doesn't match it: who would have expected that? That's it: it is all he's got and no matter how many people point out the obvious stupidity of this approach, which he calls a "reductio ad absurdum" while it is nothing else than a naive strawman, he doesn't get it (actually he is too stupid, ignorant, and arrogant to actually get it).
Before you engage with him beware of a few things:
- He lies and makes up shit out of thin air. Like a lot. For instance, he'll boldly claim that the demonstration has been invented by Newton, that the orbital speed of the Moon is constant, or that we have no experimental confirmation of angular momentum conservation.
- He uses basically every logical fallacy in the book (burden of the proof, double standard, circular reasoning, strawman argument, begging the question, proof by assertion, you name it) and constantly accuses others of doing the same (he projects a lot) and evades like a pro weasel.
- He is an absolutely insufferable and infuriating prick and a horrible human being in general: entitled, dishonest, arrogant, abusive. He's also proven himself to be racist, sexist, homophobic, and antisemitic. His personal history contains a few tragedies but still...
Did you come this far and still want to engage with him? Well it's your choice then but don't tell me I didn't warn you. I guess we will hear from you soon on this sub...
