Sounds like maybe you want acoustic impedance ? Just like optical index mismatch, or electrical impedance mismatch, you get reflections at discontinuities. Neat stuff!
Not exactly sure what you mean by air-water-air "dampening," but my suspicion is that you're referring to sound being reflected at each interface, so the transmission is reduced. Antireflective coating, index matching, impedance matching are all rich topics in physics and electronics!
50kW class laser.
Another source claims 1um wavelength with individual 1.5kW lasers in a hex pattern
unclear if it's a phased array (would be awesome) or just trained on the same target (source mentions they are "combined using a mirror" so probably the latter).
Sounds like maybe high power YAG?
I just want a button that rewinds 10-15s, turns on subtitles, and then turns them off when it catches up again. It's a pattern I do manually with some regularity.
I suppose with Jellyfin/OSS, this is something I could implement myself if I was so inclined...
Hmmm, I'm not sure I understand...
A large explosion every second has units of power, not energy. So to me this is suggesting that the train is putting out power equal to its kinetic energy per second. That's certainly not the case
it implies that the train is powerful enough to accelerate to the speed in 1s, which is definitely not true.
But that's just my interpretation.
~~I don't think your units make sense
kinetic energy has units of energy, but "kg TNT per second" is power (about 4MW). (I think just remove the "every second" and it's correct?)~~

It's maybe not that bad for a "normal" person, but Bill Nye was a real hero to a lot of young folks, be they aspiring STEM types, science enthusiasts, or just curious people. So to see him sell out
abandoning scientific integrity for a quick buck
was pretty disheartening.
You can!
Getting it published is another matter though...
Immich looks particularly good to me.
It is! Been running it for a few years now and I love it.
The local ML and face detection are awesome, and not too resource intensive
i think it took less than a day to go through maybe 20k+ photos and 1k+ videos, and that was on an N100 NUC (16GB).
Works seamlessly across my iPhone, my android, and desktop.

(Not sure if other stuff too.)
...using chopsticks of course, so you don't get your mechanical keyboard dirty.
People often complain about San Francisco's public transit
and to be sure, it's not perfect by any means (multiple separate agencies doesn't help). But the historic streetcars are pretty neat!
They're painted with the livery of various historic streetcars from all over the country (and a few international, I think). Best of all, they run alongside the modern fleet
same route, same fare.
It's a matter of perspective and use
high density one place means you can have open space somewhere else, for a given amount of land.
I'd much prefer a few large dense housing complexes, surrounded by green space, than suburban sprawl.
