Blow to US Democracy -Split from: U.S. presidential election modelling
As with the previous responses - if you’re e.g. working two jobs so there’s no free time and voting means waiting in line for 2-3 hours or more, and/or the polling place is a long bus ride away, you’re not going to vote.

Trump Pressures Raffensperger to Commit Fraud
Not as far as I know. But if he actively urged them to do it, I would think he’s guilty of sedition itself. He told them to go mess with the vote counting.

Blow to US Democracy -Split from: U.S. presidential election modelling
Remove the barriers to voting/expand the opportunities (early voting, more locations, mail-in + drop boxes, same-day registration) Pay people to vote if they do it in person - cover a few hours of low-end wages so they can afford to take off work, and make it so employers must give the time off.

Trump Pressures Raffensperger to Commit Fraud
He gave a speech right to them, urging them on, after advertising the rally. How much of a link do you need?

Blow to US Democracy -Split from: U.S. presidential election modelling
The US is not alone in electing a leader who pandered to a base with bigotry and other base emotion, while having an interesting relationship with facts. Trump is perhaps an extreme example. And by the polls, there are plenty of supporters who are comfortable with his foray into sedition and insurrection. Not half of Americans. Less than half of voters; Trump did not get a majority even when he won, and about a third of eligible voters did not vote (edit: in 2020). And we have a voting system with an intrinsic bias, and, as it happens, it’s biased in Trump’s direction.

Solar canals
As it’s over water, I would imagine this could be automated - pump water up and spray it. Powered by the solar cells. (the semi-snarky response is you wouldn’t pay an American, you’d pay an immigrant, just like with other menial labor)

How Strong the Earth's Gravitational Attraction Really Is?
You have Newton’s gravitation law. You can calculate the size of these other contributions. The acceleration from the sun is about 0.006 m/s^2, but we’re in freefall around it, so we wouldn’t feel anything even if it were larger. The moon has a small effect in changing the net value of g; this was measured back ~1931 by Loomis, comparing pendulum clocks with quartz clocks. Pendulum clocks depend on g, and there was a ~25 hour cycle of variation measured.

Do points lie on tangent lines "only?"
When speaking of fractions, in the given context, “smaller” can’t be ruled out as exactly what was meant. It’s moot, though.

Blow to US Democracy -Split from: U.S. presidential election modelling
I think the problem is that Trump is very much a Republican. For many in the GOP, he only just now crossed the line with sedition and insurrection (and for others, he hasn’t crossed it yet. Elected officials and the GOP base) The senate could have convicted him after he was impeached, but chose not to. The voters could have voted for someone else, or stayed home, but he got even more votes after 4 years of his actions being front and center. He’s been carrying out the GOP’s policies - restrictive immigration if you aren’t white and Christian, tax cuts for the rich, voter suppression, deregulation, no healthcare, abd fully-aligned with Mitch McConnell’s aim to un-do pretty much everything Obama did. No, the notion that Trump is not a Republican doesn’t hold water. To the extent that it appears to be, it’s because certain political views are reprehensible, and the site is biased towards views that reject them. That would give the appearance of this bias. White supremacy would be one example, or political stances that reject treating groups of people equally. The membership is slanted heavily toward those that are interested in science, and it’s not the site’s fault that some political groups reject science that they don’t like.

Nuclear energy vs. renewable energy
That’s one practical way of having the capacity in place. You’d basically be running the system at lower efficiency by bypassing the turbines and condensing steam without extracting work from it.

A Quantum Mechanical Interpretation of the Consequences of Special Relativity
! Moderator Note So it’s not evidence that supports your conjecture, to the exclusion of other hypotheses. IOW, it’s not support - it doesn’t show SR to be wrong. So you have no model, and no evidence. You can’t satisfy the requirements of speculations. We’re done. Don’t bring this up again.

A Quantum Mechanical Interpretation of the Consequences of Special Relativity
Will you be showing us either of the following 1. a derivation of the time dilation equation from QM 2. a way to test your conjecture in a way that is independent of relativity, or present evidence that already exists that fits this criterion I ask because if you don’t, the thread has to be closed as it does not conform to the speculations rules, which requires a model and/or evidence.

Strange correlation between Betelgeuse brightness and solar activity.

Nuclear energy vs. renewable energy
Not a lot you can do with it, other than delivering it to loads. But in doing so you have to heat up water, which acts as a buffer for variations in demand. If you increase power demand, the first thing that happens is the temperature of the water drops. The reactor fission rate increases as a result, but there’s a lag in the output (it takes time for water to complete a loop through the system) Naval reactors have some design differences compared with commercial ones. Commercial reactors are designed to run at near peak power, without much variation. The much smaller one on a sub is designed to respond the changes in load. (Carrier plants are bigger, so the size-related design constraints are lessened) In some ships/boats. Not “typically” as such. “The Russian, US and British navies rely on direct steam turbine propulsion, while French and Chinese ships use the turbine to generate electricity for propulsion”

Is positive and negative electricity nomenclature arbitrary?
! Moderator Note The argument if whether positive and negative is arbitrary must be addressed using mainstream physics, not a speculation. To frame it this way is an end run around our rules. If you have a speculation, present it and support it with evidence. You can’t just assume it’s true to buttress some other argument

U.S. presidential election modelling
A lot of the delay in these processes were accommodations to travel time in days of yore. Consider having to take a slow train across the country to deliver papers (e.g. electoral college ballots) 140 years ago or, before that, making a trip on a stagecoach. And this is after hand-counting ballots in each state, and certifying the elections. I’m guessing that took weeks, back in the day.

Center of Gravity Calc help
If you were lifting at the CoM, this wouldn't matter at all, and it's only an issue if there's significant mass that is off-center. Is the lower edge of the panel resting on the base? If so, is it fixed or does it slide as you raise the actuator?

Researchers Find a Way to Pull Carbon Out of The Air And Turn It Into Jet Fuel
"By adding heat to the system, engineers were able to combine carbon dioxide with hydrogen, split from water, to produce a few grams of liquid fuel that the authors say could work in a jet engine. " Sooooo where does that heat come from? How are they splitting the hydrogen? The article is rather coy about the conservation of energy issues with this.

A Quantum Mechanical Interpretation of the Consequences of Special Relativity
It's not elaborate. There are principle like this that are simple ways of summarizing how particles behave under a set of conditions. Light and the principle of least time (Fermat's principle), which is a truth about the path light will take, without discussing the particulars of indices of refraction. Related to the principle of least action for mechanics. Don't anthropomorphize the particles. They hate that.

Center of Gravity Calc help
The center of mass of the panel itself should be the center of the panel, if it's flat. It should be simple geometry to locate the offset from the center of rotation — r cos(theta) — i.e. (the maximum would be for the panel facing the horizon One solution to keeping the CoM over the rotation axis is using a counterweight. Is the actuator's function to change the angle of the panel?

Magnetron as a source of laser spectroscopy
Not reflection. It's absorption and emission as the electron drops into a different state. You might investigate what is already done, and why that works. MRIs work because it's microwaves and magnetic fields, which can penetrate the skull. PET scans work because the ingested material concentrates in the cells under investigation and the positrons can penetrate the skull.

Magnetron as a source of laser spectroscopy
It is also, as far as I can tell, not spatially-resolved process Agree. There was mention of nanometer scale imaging, and I don't know how you do that with micron wavelength light.
