Only that they are worthy of noting. If there is a modern system, but it happens to suck for some reason, you don't have to mention that one. So feel free to strike that "notable". Which American cities have modern train systems?
…because Staples has replaced Amazon and Temu, which both went bankrupt in 2042, and all usb-c cables are made in Papua New Guinea with only 1/4 of the pins connected to wires. Some things never change.
What's the latest with Intel's Management Engine / Minix that runs on every Intel chipset? Is that still a thing? Did they harden it? Or can you still get access?
Is there a disproportionate frequency of earthquakes in Japan? My mental model is that there would be a uniformish distribution of earthquakes all around the Pacific ring-of-fire. But even living in a U.S. state with a Pacific Ocean border (and tsunami warning signs all along the coastal towns), it still seems like Japanese earthquakes outnumber local ones by a wide margin (especially for bigger ones like M7.0+). This could also be explained because Japan has a much higher population density, so earthquakes make headlines easier. And the devastating earthquakes in 2011 could make people more sensitive to earthquakes in Japan. But I guess my question is partially answered by a map of earthquakes on the Wikipedia page about the ring of fire:
...where is does seem like the West Coast of the North America has lower quake frequency. Here's to hoping the Cascadia subduction zone remains quiet for a while longer.
No reason that the rate of subduction has to be the same everywhere. Some of the plate boundaries might be moving into each other in different directions too, the coupling between plates is not necessarily the same everywhere.
Anyway, in the case of Cascadia, remember that the lack of big earthquakes over the past 100 years is probably telling you that we just happen to live in a time where strain is accumulating (D:)
Yes, I guess we should hope for a lot of M6 quakes in the near term. Or hope that in 100 years the infrastructure will be much more quake resilient than today.
Schwarzschild radius for something with the mass of the electron seems like it would be ~1.35*10^-57m. But I guess that is for a neutral object. I suppose the electric charge might be enough to keep it from collapsing into a black hole? I wonder what the smallest Schwarzschild radius is for something with the charge of an electron?
That kind of makes me wonder if quantum mechanics is necessary for gravity to work properly. Like, without tunneling, photons wouldn't be able to escape the gravity of the particles that they originated from resulting in a dead theoretical universe.
In all seriousness, I believe that the resolution of the diameter of the electron would shed a lot of light on the fundamental mysteries of physics and the architecture of reality:
Like, how far below the Planck Length can things go in practice?
What "New Physics" can describe interactions on those scales?
Is space fundamentally granular or continuous?
Is it possible that the electron is a composite of smaller particles, just as the proton is a bag of quarks?
And related to your own musings, what role does quantum foam play?
It's all extremely mysterious and tantalizingly out of the reach of the best conceivable instruments.
