Rights
In case there’s any question about the US version of this right, a quote from recent ruling on banning drag shows https://www.thefire.org/sites/default/files/2025/03/Opinion - Texas A%26M Queer Empowerment Council v. Mahomes%2C et al..pdf "To ban the performance from taking place on campus because it offends some members of the campus community is precisely what the First Amendment prohibits." (p.28)

Which LLM is the best at doing scientific literature searches?
I asked all three who built the first rubidium fountain clock. They gave three different answers. Perplexity got it right, and gave a decent summary. Consensus gave a list of references but couldn’t figure out that 2004 was earlier than other dates.

I think she runs for senate first. Gillibrand’s proven to be a wet noodle these past two months, so maybe AOC runs for her seat next year.

Is Religion basically; Smart = Good, Dumb = Bad
That’s the thing with secret symbolism. It can mean pretty much anything you want it to. And we tend to see things that we want to, or what our brain fills in, like with pareidolia The OP is way too vague to generate meaningful discussion, as evidenced by several posts that follow it.

Help with a physics question.
What have you done so far? How do you measure time? What uses kelvins and how is it measured?

Question about Pi
It depends on the precision of numbers you know, usually limited by your measuring instrument. If you’re measuring a distance and can only do so to the nearest meter, that would tell you . e.g. you measure 11 meters, so you have 2 significant digits. If you could measure down to the cm, e.g. 11.27 m, then you have 4 significant digits.

Specifications of microwaves used to entangle macroscopic oscillators?
The frequencies are given, as are the pulse durations. The power levels might be described in a previous paper; I notice several Teufel papers in the references. I’m not sure what lidar has to do with your inquiry; they mention the microwave resonator; the frequency width is going to be determined by the details of that circuit.

Question about Pi
√(78.500/3.1416) = 24.987 so you're rounding the answer. Let's say you wanted to change it so that the result was affected, to say, 5.1. 5.1^2 ≈ 26. You'd have to use π = 3 to get there The issue here is "significant digits" which is the precision of the numbers you use. Each digit you add increases the precision of the result, but that increase in precision gets smaller with each digit you add. Let's say you were using a constant that was 4/9 = 4.4444... 4.4 is 10% bigger than 4 - that's a big change 4.44 is 0.9% bigger than 4.4 4.444 is 0.09% bigger than 4.44 (and so on) each digit has a smaller impact on how close you are to the correct value The impact on the answer is an equation depends on how many digits the other numbers in the equation have and whether you are adding or multiplying. For multiplying, if the answer only needs 1 digit, and you're rounding, only 2 digits matter (the second digit tells you if you round up or down) so you don't need more than 2 digits in your constant, since a 0.9% change in the answer won't affect the result. You want a 3-digit answer? Then use 4 digits in the constant. etc. etc. For adding, it's just where that last significant digit is. If the result is going to be rounded to the nearest 10, you only ned the "ones" digit, i.e. you use 4. If the result is to the nearest 0.01, you need to use 4.444 (anything beyond that is going to be rounded off)

Democracy and military strength
A clan is a group based on kinship, i.e. extended families. So no, you probably wouldn’t move to a new chief based on not liking the one you have.

Galaxies seem to have a preferred direction of rotation
Relativistic beaming is from the relativistic doppler effect https://en.m.wikipedia.org/wiki/Relativistic_beaming “In physics, relativistic beaming (also known as Doppler beaming, Doppler boosting, or the headlight effect) is the process by which relativistic effects modify the apparent luminosity of emitting matter that is moving at speeds close to the speed of light. … How all of these effects modify the brightness, or apparent luminosity, of a moving object is determined by the equation describing the relativistic Doppler effect (which is why relativistic beaming is also known as Doppler beaming).” edit: Here’s one of the cited references, by the same author https://www.degruyter.com/document/doi/10.1515/astro-2020-0001/html They mention a Doppler shift of the bolometric flux; this means the “brightness” they are measuring is related to total energy, and blue-shifting does increase that. It’s not simply number of photons. more: https://en.m.wikipedia.org/wiki/Luminosity

Galaxies seem to have a preferred direction of rotation
There’s relativistic aberration (relativistic beaming) which means light is preferentially emitted in the direction of motion, but at speeds of less than 10^3 km/sec (our speed is ~230 km/s) it shouldn’t be that big

Pro’s and Con’s of Elon Musk
Starship troubles “Starship Was Doomed From The Beginning” https://www.planetearthandbeyond.co/p/starship-was-doomed-from-the-beginning “This is why Starship, in my opinion, is just one massive con. That is the real reason why Starship was doomed to fail from the beginning. It’s not trying to revolutionise the space industry; if it were, its concept, design, and testing plan would be totally different. Instead, the entire project is optimised to fleece as much money from the US taxpayer as possible, and as such, that is all it will ever do”

Is life just an illusion?
So if I hit you upside the head with a club it would hurt less if I called the club a pillow? Or I called it a hug instead of a vicious blow? Propaganda works, but only to some extent. as in “don’t piss on my back and tell me it’s raining”

What is DEI, and why is it dividing America?
I think a lot of the issue is white men who say they are Christians, but whose behavior does not reflect the actual teachings of the religion. (There are a number of clergy who fall into that category) It’s all for show, to claim membership in the tribe, in order to exert power. At best they are “a-la-carte Christians” who pick and choose which tenets they support, while ignoring or actively opposing others, to suit their needs, and never acknowledging these transgressions. (e.g. gleefully deporting immigrants, or supporting those efforts) —— Anyway, if there’s any question about the GOP stance, they’ve erased the Navajo code-talker info from DoD websites. Huge contribution to the war effort, doing a job white men couldn’t have done, so there is no question these people were not hired at the expense of a white dude.

Made up by your mind? An illusion? So if I open a vial of some noxious transparent gas, but say it’s air, you won’t smell anything? I don’t know what “we live in concepts” is supposed to mean.
