This seems to say his proposed "Theory of everything" is lacking in several regards and not a good candidate for scientific or academic research. I don't see how that makes him a clown. He's interested in physics, educated in it, and made some effort to contribute that doesn't seem to have panned out. That strikes me as laudable behavior and not like a "clown". Perhaps you'll say he is a clown because he really belie…
The same could be said in praise of every crank. Presumably if he's a crank about physics, he could also be one about Covid.
As I understand it Eric has his theory, he wrote it up, and published it on his YouTube channel or a similar platform and a few interested people critiqued it. Great. It would be one thing if he was emailing the editors at Nature every week with a new crazy idea, that would be "crank" territory. That doesn't seem like what happened.
Regardless, this tweet is about Eric's brother who had a conversation with a doctor about possible use of ivermectin to treat Covid. Entirely separate from Eric Weinstein's physics credibility.
