What does it mean for the US now? Like what does second term of Trump mean for the US now?
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.

But Trump’s (narrow) win didn’t have the coattails one might have expected at the state level; Democrats broke the GOP supermajority in North Carolina, have a one-seat majority in the Pennsylvania House, and flipped 14 seats in Wisconsin (where they had new electoral maps)

You’re getting ahead of yourself. Tariffs he can do, at least to some extent. These things you describe here are not within his power so one shouldn’t just assume they will happen. More moving parts, and there will be pushback, and that will slow things down.

Force on the rocket in the rocket problem
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.

Force on the rocket in the rocket problem
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.

Force on the rocket in the rocket problem
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

Yeah, this may be about kickbacks for exemptions from businesses that would be harmed, and kickbacks for tariffs that help businesses.

Measuring c (split from Is foundational physics stuck?)
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.

Lichtman's 13 Keys to the 2024 Election
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.

What does it mean for the US now? Like what does second term of Trump mean for the US now?
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/

Measuring c (split from Is foundational physics stuck?)
If I measure the speed of light with the spinning mirror method, there’s nothing in that apparatus that relies on the speed of light being what it is, or on the interactions happening at c. The mirror spins at some speed, whose value is not critical to the experiment. Everything else is static. If c changed, nothing about the apparatus is affected

No, but that might just be an issue of imprecise terminology Yes, and this is the crux of the problem

It’s also possible that this means he produces a report that will be released, which would not happen if he were fired.

Measuring c (split from Is foundational physics stuck?)
There are absorptions to virtual states which accounts for light slowing down in a medium, but that presupposes a composite system like an atom, so there are real absorptions possible as well, and an electromagnetic interaction. With gas molecules you have the ability to shed energy in inelastic scattering. Where’s the evidence a similar distribution in DM? What’s the formula for the distribution?

Spinning a cored coil...
Yes. We had a physics lab when I was a TA that detected the earth’s field this way; the students measured the voltage in different orientations. (An interesting anecdote is that students in one corner of the room got a different answer because there was an NMR lab in the building, and the field in that corner was measurably different.) edit: there are a few schools that list a similar lab online, such as https://www2.oberlin.edu/physics/catalog/demonstrations/em/earthinductor.html

Measuring c (split from Is foundational physics stuck?)
H-K does not show a preferred inertial frame Now it’s my turn to say you didn’t read/understand what I wrote. Air not being inside atoms only eliminates one possible effect, because atmospheric pressure does, in fact, affect some atomic clocks. But it does not correlate with gravitational time dilation. My point still stands: you need to be able to quantify the effect, rather than give a hand-wave. How does it slow light if there is no E-M interaction?
-
Measuring c (split from Is foundational physics stuck?)
You can devise experiments that don’t rely on the value of c to determine c, so I’m not sure why this matters. Any clock able to discern gravitational time dilation has the atoms in a vacuum chamber, so this isn’t an issue. Further, you have multiple designs of clocks that would not have the same response to environmental perturbations, so they would not give a consistent shift if the result was from such a cause. And “maybe it’s air density” is not a rigorous objection without a model of how it should depend on air density.

Force on the rocket in the rocket problem
Except there is, since evaporation would exert a force. The v is the velocity of the ejected mass relative to the bulk mass. It doesn’t change in the other frame If that was your point, it was not at all clear to me.
