She has several other good videos too. Her channel is fairly young but this one is probably her best so far. I do fear it runs afoul of being catnip to the kind of person that comments on every dark matter article with "well I've always been skeptical of dark matter" or "particle physics needs to think outside the box". And if you are, well, watch her dark matter video too but you won't like it for the opposite reason that you'll like this one. Don't say I didn't warn you.
Anyway she's a great communicator and has the right kind of sass (this is probably her sassiest). Give the rest of her catalogue a look.
I was all ready to be pissed at the dark matter video but I surprised myself by liking it so much. Yup, definitely measuring mass, no getting around that. Is it a screwup in our measuring ability? An artifact of an even-weirder-than-imagined spacetime? Can't tell, doesn't matter. That isn't what's being discussed. It's mass, it's out there. Go from there. I got the feeling her real ire is for people who just generally go "man, I think you're just, like, making stuff up".
Not so much that she should have cut the video, but written out a script for a 10-minute video and recorded that. For instance, there's like a 3 minute digression about a popular science book whose punchline is that string theorists sound like crackpot physicists, and that's basically all the information she wanted to convey in that digression.
Damn you, I had to hunt, it was the one self described with the deliberately misleading clickbait title:
the most important material in science
The most important material in science is glass. This is a video about the history of glass. Glass is important. Glass is complicated. Professional scientific glass blowers are the coolest people in the world. And a little discussion on art versus science.
TBH I stepped through it, it seems pretty good with no obvious errors and it's on the aspirational "to watch" list .. I worked with a few glass blowers for both craft and science applications some decades back so I have a few solid books on the history of glass and a few hundred hours batching glass recipes.
My benchmark for a great glass video is (say) any > 30 minute full piece video of Lino T. working:
