I understand this line of thinking but I don't feel that it's particularly relevant. It seems to be born out of a point of view that physics theories are a binary. We either fully support them with everything we have or we completely denigrate them to the point of demonizing anyone who shows any interest in them.

Surely this can't be the best approach to discovering new physics?

Which is how I view these people. The result of a natural frustration that physics discoveries do not seem to be happening at the rate that they should. I'm not sure they have _the_ answer but I understand _why_ they're acting as they do.

Why this outcome bothers anyone is completely beyond me and now makes me genuinely wonder if there is simply too much gatekeeping within the field.

You're arguing with an oversimplified model of the complaint about Weinstein. It's not that Weinstein has a theory that's orthogonal to mainstream physics, but rather the means with which he pursues the inquiry. He doesn't write real papers, when he released the GU paper he copyrighted it and claimed it as a "work of entertainment", in effect demanding that the rest of the field not cite and address it. That's not how papers work.

The problem, as I understand it, is that Weinstein simply isn't "doing science". He's "doing big thinkies" and then complaining when the world doesn't snap to attention. That problem has not much at all to do with his specific ideas.

I used to be in charge of technical measures for controlling crackpot submissions at arXiv because we were trying to get a very ornery physicist from not getting us in trouble sending nastygrams to HBCUs and such. The endorsement system was my work.

Two things we noticed were: (1) there weren’t really that many crackpot submissions but they were concentrated in certain areas that really would have been overrun with them. Crackpots don’t ever seem to find out that there is a big mystery in how cuprate semiconductors superconduct or what determines how proteins fold or even that there is such a thing as condensed-matter physics (e.g. most of it!) (2) Crackpots almost always work alone, contrasted to real physicists who work with other physicists which was the basis for the endorsement system. We’d ask a crackpot “who else is working on this?” And always get the answer “no one.”

From having done that work but also having an interest in the phenomenon, being too well read of a person to make it in academia, and personally meeting more than my share of lunatics, that it is really a psychiatric phenomenon really a subtype of paranoia

particularly involving grandiosity but sometimes litigiousness. It boggles my mind that Weinstein threatened a lawsuit over criticism of his ideas, something I’ve never heard of a real scientist doing —- I mean, scientific truth is outside the jurisdiction of the courts. I met

and did not get to put his motor on my bench but I did set up some equipment on my bench that showed that the equipment he was demoing his motor on could give inaccurate readings and he had this crazy story of sueing the patent office and using his right-wing connections with churches and the Reagan administration to bully NIST into testing his motor.

But... they're the ones doing the demonizing... of pretty much everyone who disagrees with them?

"DISC" is literally just shorthand for "people who disagree with me are conspiring."
