If you already understand the concepts you're not gaining much by watching the video.
If you don't then I'm sure it's better than nothing but idk if stock footage is where you should be developing your mental model of how a tire hydroplanes or how a paved transfers load into what's below it.
C'mon. I know everyone on HN just can't help but glaze anyone who deals with "real world things" rather than 1s and 0s but this is absolutely not one of his more original content videos. You can't simulate landing aircraft using a clear plastic box (one of his better props) like you can soil conditions so you get what you get.
Is it the desired behavior of HN that silent upvotes are for agreement? (Instead of a positive comment that doesn't add substantially to the discourse?)
Probably a better title would be "Found a way to make people aware of opportunities for kindness"
The hypothesis that they propose is that 'the addition of an unusual character like Batman on the subway made people who otherwise may have been lost in their own thoughts or podcast look around and be more aware of people around them, and this more likely to notice the pregnant woman and offer their seat'
I'm looking forward to the follow up paper to test the hypothesis.
