  • I would definitely call it theft in most cases, because in a capitalist system, labor is structurally coerced and is not giving up its surplus value freely, as you basically said yourself in different words. Or perhaps more succinctly, I would call slavery a form of theft. But I agree it isn’t “wage theft” because that has a more specific understood meaning related to what’s owed according to the law.















  • Making an educated guess as a layperson, besides some satellites that are geosynchronous but not geostationary, I’d assume those are primarily old geostationary satellites in graveyard orbits - when they’re EOL, satellites in those orbits are supposed to perform a small boost out of them, usually adding a few hundred km to their orbit’s radius (GEO is about 36,000km in altitude, so a few hundred km is relatively small). Then, without station keeping, I believe they should naturally precess around the Laplace plane, which will range between roughly Earth’s equator and the ecliptic plane (the plane of Earth’s orbit). At GEO altitudes the Laplace plane is about 7.2 degrees inclined from the equator. I believe that would mean, starting at the equator with an inclination of 0 degrees, these satellites should precess to about 14.4 degrees and back to 0 over several decades (excluding other perturbations, of course).

    I found this online which would seem to confirm at least the mechanics: https://amostech.com/TechnicalPapers/2013/Orbital_Debris/ROSENGREN.pdf


  • There’s an argument that the First and Second Amendments should be treated differently because of how they’re worded. The First flatly says “Congress shall make no law…,” which makes permits seem like an infringement. The Second, though, begins with “A well regulated Militia…,” and if we take “well regulated” seriously, it can be seen to imply regulation is part of the right itself rather than contrary to it. You could even push it to a more radical reading: that being free from excessive gun violence is itself an implied right, since “well regulated” might be taken to point in that direction.

    Not necessarily saying I agree with that reading (honestly I don’t think I have the legal background to have a real opinion except oughts and shoulds) but it’s an argument I’ve seen made and it seems internally consistent.





  • I get where you’re coming from, and I do feel like Chani really suffered from the adaptation, but I felt like it was more due to screentime and not having internal thoughts than changes made. I felt her being skeptical at the beginning was both a great change to her character (it feels like she falls in love with the Muad’dib Paul becomes, not the Atreides he was) and a really good way to carry themes of anti-messianism into the movie where the book relied on philosophical asides. It also provides a natural foil to Stilgar’s zeal and Jessica’s manipulation, presenting Chani as more aligned with Paul himself.


  • Somebody please correct me if I’m wrong, but I believe due to the very low refractive index of about 1.0003, particles need tremendous energy to produce Cherenkov radiation in atmosphere. So the demon core flashes (while perhaps some negligible part Cherenkov) were probably mostly just from the ionization of the air, and subsequent nitrogen/oxygen fluorescence.

    If my awful phone math is right, you’d need about 21 MeV of energy for an electron to produce Cherenkov radiation. I think the processes producing energetic electrons here (Compton scattering, some pair production, photoelectric effect, internal conversion, delta rays, and Bremsstrahlung cascade I believe) should regularly produce energies around 10 MeV at most (from Compton).


  • Well, I took the plunge. From the thesis:

    The diffuser introduces the pressurant gas into the propellant tank as a critical component of the pressurization system in a liquid propulsion engine. Element present in both pressurization systems (self-pressurization and by inert gases), the diffuser makes the pressurant enter the propellant tank at a desired direction and velocity to keep the pressure inside the tank at the design level during the pressurization activities without the engine working (on-ground operations or during coasting phase) and to avoid the creation of zones where the operating pressure falls below a threshold value of NPSH during engine firing.
