I give, what is the elephant?
Either "the vaccine caused this" or "Long COVID isn't real". Probably the former (or both?) considering the replies made by the commenter.

#42I've heard that back in the day conservatories would use this as part of their entrance exam. It is a great way to test if someone can recreate a specific pitch by ear.
I wonder what percentage of the failures to recreate a pitch are due to people not being able to adjust for the difference when they're hearing it through their own skull.

#43Dianna (Physics Girl) is currently experiencing severe complications from ME/CFS/long COVID. Per the last update on her twitter: The last weeks were scary. ER visits were hard. Dianna still can’t walk, or even sit up in bed. But we see signs of progress. Sleeping more. Eating more. More treatments coming.

Long covid researchers-- is the current body of research converging on any cause(s) for the myriad long covid symptoms? Endothelial damage?

I have nothing against the video, and I am all for making science exciting for the broader audience. I just am not sure why it is at the top of HN.
Some people might be aware of her situation along with the impact of her work and maybe think that having one of her videos at the front page of HN could be a way to help. At least that why I upvoted it.
Seems you are right and I would have saved my criticism with that knowledge. Though I do think that information should have been in the submission title then.
Ah well, best wishes to her.

Well, a Ph.D.-level explanation wouldn't be nearly as approachable or interesting to the 1.2M people that watched it.

I watched the video a few years ago.
Before watching the video, I though the trick to break the cup was to sing very loud and very close to the tuned to natural resonance frequency of the glass, so the movement of the glass and the air inside are so big that breaks the resistance of the glass suddenly. Like swinging a swing until you got a 360°.
In the video I learned that the important part are the micro cracks of the glass. If you sign loud and tuned up, the micro cracks begin to grow, and grow, and grow, until they are so big that one of them is big enough to break the glass.
The differences are that it's also important to sing for a long time to make the micro cracks grow, and that the exact moment is difficult to predict because it's not when the singer is extremely tuned but when the invisible crack are big enough.
(I also learned that it's possible to cheat and make a small crack on the border to break the glass faster and consistently and impress your friends. (I broke a glass singing, so I never had an opportunity to used that trick anyway.))

I'm going to go with 0%, given that the fundamental pitch of a sound is unaffected by material interference. I suppose exceptionally high-pitched tones above several thousand hertz might be affected, but nothing within the range of a human voice.

seems a strange kind of vaccine side effect that only occurs directly after you contract the actual disease
It's a real possibility https://en.wikipedia.org/wiki/Antibody-dependent_enhancement but it's one of the things that are checked in vaccine candidates before they are authorized for the general public. Quoting Wikipedia:
> Prior to the pandemic, ADE was observed in animal studies of laboratory rodents with vaccines for SARS-CoV, the virus that causes severe acute respiratory syndrome (SARS). However, as of 27 January 2022 there have been no observed incidents with vaccines for COVID-19 in trials with nonhuman primates, in clinical trials with humans, or following the widespread use of approved vaccines.
