  1. Der_Neugierige has announced they are leaving. We have locked the door behind them, so that their declaration doesn’t turn into a lie.
  2. ! Moderator Note Well, I do care about our dictatorial rules, and rule 2.7 says, in part Links, pictures and videos in posts should be relevant to the discussion, and members should be able to participate in the discussion without clicking any links or watching any videos. Videos and pictures should be accompanied by enough text to set the tone for the discussion, and should not be posted alone So you must assume people won’t watch the video. Your discussion must stand on its own. ! Moderator Note Yeah, that’s inappropriate.
  3. ! Moderator Note The title is problematic regarding rule 2.1, and our rules preclude opening a thread using just a video, without supporting discussion. From rule 2.7 Links, pictures and videos in posts should be relevant to the discussion, and members should be able to participate in the discussion without clicking any links or watching any videos. Videos and pictures should be accompanied by enough text to set the tone for the discussion, and should not be posted alone Any re-introduction of this or any discussion must comply with the rules.
  4. That’s faulty logic; there are a number of reasons that people downvote posts, and we know this from the many discussions on the topic. They could be downvoting for the same reasons that others post in disagreement - that you are e.g. posting faulty arguments. I’ve seen upvotes for good arguments from people who had taken a contrary position. To assume that they are downvoting because you are revealing some uncomfortable truth might be projection of your own motivation. People are more varied than that. Downvotes are not supposed to be a source of pride.
  5. No idea. I wouldn’t be surprised if it impacted the motion of the ionosphere (the primary source of the magnetic field), since you’d expect a decent temperature gradient, but we have a decent temperature gradient here on earth. Proximity to the sun is another variable, and I don’t know how that all combines.
  6. That’s my understanding. There’s a little nitrogen, and the oxygen is all bound up in heavier molecules.
  7. The atmosphere of Venus is mostly CO2, so it’s heavier. Venus also has a strongly circulating ionosphere, which creates a magnetic field - it’s not an internal source.
  8. The protocol suggests that this is the likely result.
  9. One objection I have is the suggestion that the fields are propagating well away from the wires. But those fields drop off with distance, and radiate in directions away from the load; they don’t turn around like they’re homing in on the light bulb. Also: What if you send the wire into a volume that’s encased by a magnetically shielding conductor? The parallel E field would be shielded as well. So yes, the energy is contained in the fields - you could calculate the KE of the electrons and see e.g. that 1 Coul of charge with V = 1V, moving at ~1mm/sec, does not have anywhere close to 1 Joule of KE - but these fields can’t be out in random open space

    Can you give some more context to this? People do, so perhaps you just need to look a little harder. ! Moderator Note You started this thread. Nobody was pointing fingers.
  11. Do you know if these reactions were occurring in the span of time the recipients are waiting after the shot (15 min was my experience); it sounds like that, given the “prompt attention” If so, PhilGeis’s “beyond surveillance” objection is moot; these numbers would not be anecdotal, since everyone is being observed.
  12. What manner of failure? breaking, or deformation? Given that the latter is a plastic property, the former shouldn’t be expected. But if it were maximally able to undergo plastic deformation (the necessary force approaches zero), it would deform under its own weight, which is hardly useful. So that just means there is a threshold force that needs to be applied.
  13. swansont replied to StringJunky's topic in Politics
    I’m pretty sure they were victims of the shooting. ”a person harmed, injured, or killed as a result of a crime, accident, or other event or action.” The question was whether the were victims of a crime.
  14. swansont replied to StringJunky's topic in Politics
    No, they were at a protest in support of such people. And according to the judge, they were not victims.
  15. If you’re learning things, and correcting misconceptions, yes.
  16. But it’s so small compared to the other accelerations. And since we are orbiting, we accelerate toward the center without actually moving toward the center (assuming a circular orbit) IOW, something in a circular orbit is falling toward the center, but is moving sideways so it keeps missing, and gets no closer to the center.

    Black, life arguably in danger, convicted of killing her abductor/trafficker edit: xpost; details above
  18. swansont replied to StringJunky's topic in Politics
    That’s a generous interpretation, because black defendants aren’t treated the same way. Chrystul Kizer was convicted when she killed her abductor/sex trafficker. Same part of the country. I daresay if someone who is armed with an AR-15 can be in fear for their safety such that they can use deadly force, just about anybody can make the same argument, and it would likely be a better justification. Somebody, say, “wielding” a skateboard.
  19. I think the early approach was because credit cards and their fees were new, and perhaps merchants didn’t want to be seen raising prices. Discounts let them keep some more of the profit. But two things happened in the 70s - wider adoption, and then rampant inflation. I imagine it’s easier to hide a price bump to cover your interchange (and other) fees when you’re doing it anyway, and once you assume most people will use credit vs cash, you’re going to price that in anyway. I pay rent through electronic transfer now, too, instead of writing a check. Been like that for at least 7 or 8 years for me. (their web portal isn’t great, but I know what the foibles are now)
  20. I recall hearing about this being more widespread when credit cards were much less common, ~50 years ago. You could go into some small businessed and get a small discount for paying cash, if you asked.
  21. swansont replied to StringJunky's topic in Politics
    Yes, and I phrased something poorly earlier that suggested otherwise. The shooter being white afforded much more leeway than if it were otherwise.
  22. swansont replied to StringJunky's topic in Politics
    It's not present tense. The system is broken. It was designed that way. The default is that if you're white, it is legally plausible to fear for your life from anyone with darker skin or different views, regardless of circumstances. This is just another example. Civil court has a lower burden (preponderance of evidence vs reasonable doubt) so this may not be over (see OJ Simpson) and as I alluded to above, it's been suggested that federal charges might be in play because he crossed state lines (I'm not a lawyer, tho)
  23. swansont replied to StringJunky's topic in Politics
    Disappointed, but not shocked. Such is the legal system of the US. added: To paraphrase from Mississippi Burning "These hayseeds will never prosecute. convict. We've got to get 'em in federal court! Violation of civil rights!" Along with the judge suspending the sentences after a conviction.
  24. In the US I've seen lower prices on fuel if you pay cash vs using a credit card.
  25. https://www.forbes.com/sites/startswithabang/2018/08/30/our-motion-through-space-isnt-a-vortex-but-something-far-more-interesting/?sh=1edacf3d7ec2 The Solar System moves through the galaxy with about a 60° angle between the galactic plane and the planetary orbital plane.
