! Moderator Note We don’t care. ChatGPT is not a technical resource. This is not in accordance with our policy on its use https://www.scienceforums.net/topic/133848-policy-on-aillm-use-on-sfn/ Further, there’s not enough science in your post for it to be discussed in speculations. You’re free to ask questions, but if you have something to propose you need math so things can be quantified and you can make specific predictions.

Right. Stock prices generally reflect expectation of future earnings, so it’s not November sales that matter, it’s next year’s, and the year after. And tariffs on Canadian goods would bump oil prices up, so if gas is more expensive, EV sales should continue to be robust.

I think he stays to make sure investigations into his companies get derailed and the gravy train keeps flowing to him.

I think that there’s going to be a lot of noise and not much action for a while. It’s not so easy to fire federal employees. I think the first attempts will result in some lawsuits and probably an injunction and blaming of the “deep state” because baby didn’t get his binky. Eventually various organizations will be able to re-do their org charts to reduce billets, but I’ve seen efforts to do this take more than a year before implementation. And other than the political appointees, few are going to be willing to reduce headcount unless there’s also a reduction in expected results, but that’s not an improvement in efficiency. Budget cuts will also affect this, but that, too will take time to bubble through. And representatives won’t like losing money coming into their districts. People don’t always realize that a lot of federal employees work outside of DC. Another tactic might be to shift even more work to contractors, even though that doesn’t really make anything cheaper or more efficient. They’ve been doing this for years. (the number of federal employees hasn’t changed all that much for the last ~50 years, even though the population has almost doubled) But it does give money to businesses. My bet is he’s going to try and fire any Biden administration holdovers before any of his own people.

No, actually, I don’t. If you didn’t mean cabinet, you shouldn’t have said cabinet. Your imprecise wording not anybody else’s fault. Stop trying to blame others for not understanding.

Perhaps not explicitly but it’s right there in the derivation.

Musk isn’t going to be in his cabinet, because the so-called Department of Government Efficiency is not an actual department. Congress can create new departments, but the president can’t. Musk and Ramaswamy will be advisors, and not government employees.

Congresscritters that need to be re-elected in two years might act in self preservation, especially if things go sideways quickly, and they know they’ll be tagged with it. In state legislatures, too. 37 states have gubernatorial elections in the next two years. And just citizens exhibiting passive non-compliance, or at least not complying in advance.

The differential equation being used does not have m1 and m2 in it. You can’t mix and match these equations and methods. dm is very small, so from one instant to the next the rocket’s mass is approximately constant.

No, that’s not correct. A change in momentum means the difference in momentum at two different points in time. That’s what the 1 and 2 refer to in my equation. If you have two masses, they each have a velocity at each time. For a mass M that ejects a mass m, the difference in their momenta is not the change in momentum. The change in momentum of that system is zero, since there is no external force.

It’s not Trump’s common sense that matters. Trump being a racist isn’t even a close call. Half of Americans didn’t vote for him. He got around 77 million votes. The population of the US is around 335 million, so even accounting for some of the population not being citizens, it’s about a quarter of Americans.

As Genady has pointed out, the v in the equation is the velocity of the ejected mass relative to the parent mass, which is not frame dependent. The change in momentum will also not depend on the frame, since any velocity term from a frame change that’s included in the calculation cancels out — it’s added to both values. frame 1: the change in momentum is mv2- mv1 In frame 2, moving at u wrt frame 1, it’s m(v2+u) - m(v1+u) = mv2- mv1

Um, what? Holding someone accountable typically is in the context of illegal or improper acts. How does supplying weaponry to an ally, with whom we have treaties and agreements, and for which there is congressionally-approved support, qualify? Everyone? He didn’t get half of the votes cast, and about two-thirds of registered voters didn’t vote for him. All hat, no cattle, as they say.

Measuring c (split from Is foundational physics stuck?)

So, it’s magic ! Moderator Note Or at all, since you have given us nothing but hand-waving. No model, no evidence. As such, this doesn’t fulfill the requirements for discussion- 31 replies

How does DM form a system? Now you need two particles, you have to have an interaction to form the bound system, and you have to be able to virtually absorb photons but not have resonant absorption or dissociation, and you need electromagnetic interactions. You could use a pendulum clock for that. -
Thank you for confirming that this is utterly unscientific. It’s more of a cult, like when someone keeps predicting the aliens will show up, and then comes up with an excuse when the target date comes and goes with no aliens. But keep believing! All that’s missing is a plea for more money.
-
Not really. It’s prediction based on past behavior. You can believe, as iNow points out, a ghost-written book, or you can look at his numerous actual business failures. The latter carries more weight, IMO. It’s time we get past the myth that the very rich are geniuses. They keep showing us they’re not. Which was as bunch of people predicted. i.e. we knew we didn’t need a wall. Same economic “genius” on display as saying China will pay the tariffs.

From where does your insight come? He did tariffs in his first term, and had to bail out farmers when China stopped buying US soybeans. “A U.S. Department of Agriculture study found the retaliatory tariffs reduced U.S. agricultural exports by $27 billion from mid-2018 when the tariffs were imposed to the end of 2019. Soybeans accounted for the majority of the decline” https://taxfoundation.org/blog/tariffs-trade-war-agriculture-food-prices/
