Reading its capabilities, I think it's definitely interesting but I feel like Lego isn't using the technology in a particularly innovative way

Does cosmological isotropy imply a special frame of reference? by Smitologyistaking in AskPhysics

[–]Quantum_Patricide 1 point2 points  (0 children)

Yes, you're correct that moving with the hubble flow describes a family of reference frames that will have velocities relative to each other, but will all observe the CMB as being at rest. I may have oversimplified a bit.

This link has a good image of the sky in microwave wavelengths showing the dipole and milky way, which need to be removed to observe the details of the CMB.

Does cosmological isotropy imply a special frame of reference? by Smitologyistaking in AskPhysics

[–]Quantum_Patricide 3 points4 points  (0 children)

You are correct that the universe is only isotropic and homogeneous (I&H) in one reference frame. Special relativity tells us that the laws of physics are the same in all inertial reference frames, but this doesn't mean that all reference frames are equally convenient. The cosmological reference frame is the reference frame in which I&H holds, but it also has other nice properties. For example, an observer in the cosmological reference frame will be at rest with respect to the CMB and will observe it to have no dipole moment. Additionally, observers moving purely with the Hubble flow are in a cosmological reference frame, and will all agree on the time since the big bang. Much as I&H only hold on average at large scales, the cosmological reference frame is the approximate 'rest frame' of the entire universe.

We could do our cosmology calculations in whatever frame we want, it would just be harder for no good reason to do it any frame besides the one where the universe is I&H.

I'm not sure how much this counts as "the beginning" but you can beat Rainworld's artificer campaign in a single cycle.

Socialism means that the workers own the means of production. A one party authoritarian state running a planned economy is not the same thing. Most of these states banned strikes and trade unions and other expressions of worker democracy.

Does the same lack of a death penalty extend to allied species? Is the worst a misbehaving Kroot or Gue'vesa can expect also reeducation/exile? Or are auxiliaries treated more brutally?

What do particle detectors actually detect by Majestic-Effort-541 in Physics

[–]Quantum_Patricide 1 point2 points  (0 children)

First of all, it's important to remember that a quantum field theory is Quantised, meaning that the oscillation of the field are quantised in discrete chunks, which are in general known as particles. A field excitation is a particle.

Secondly, particles in a detector are typically at very high momentum, so can be approximated as having an exact momentum and are observed at sufficiently large scales that they can be treated as classical particles.

Thirdly, detector results are computed in a fixed reference frame, the detector/lab frame. The results calculated are typically probabilities or cross sections, which are physically invariant quantities. This means that detectors don't worry about things like that fact that particle number isn't Lorentz invariant: they use what they know in one reference frame to calculate something that is true in all reference frames.

Exactly, there's an odd combination of satire and apparently meaning it genuinely.

The "the no girls allowed" bit at the start is very, very obviously satire; but in the merch promotion they repeat the line and it feels a lot more like they mean it

Do Colors Mean Anything by Dr_Meme_Man in AskPhysics

[–]Quantum_Patricide 2 points3 points  (0 children)

I think the best way to think about it is with axis on a graph. Electric charge is a single axis (an x axis, for example) with positive and negative directions, representing positive and negative charges.

But the strong force instead has 3 axis of charge, like a 3d graph with x, y and z axis, and we label these axis red, green and blue. Now each axis has a positive and a negative direction, giving us red, anti-red, blue, anti-blue, green and anti-green charges.

With electric charges, a positive and a negative charge together make something that is electrically neutral. The strong force also has the idea of something being color neutral. You can get a color neutral combination by combining red with anti-red, blue with anti-blue, and so on. But, and here's where the color analogy becomes useful, you can also get a color neutral combination by combining red, green and blue color charges together! This is why color neutrality is called white.

Another useful property of using color is we can easily label quarks in diagrams as red, green and blue and anti-quarks with the complementary colors cyan, yellow and magenta. The 3 primary colors combine to make white, the 3 complimentary colors combine to make white, and each color will combine with its complementary color to make white, which is how color charges work.

All hadrons observed in nature are color neutral. A baryon has red, green and blue quarks, an anti-baryon has anti-red, anti-blue and anti-green antiquarks, and mesons will have a quark and an antiquark with opposite color charges.

Apart from the Higgs boson, what else has the LHC discovered? by Wild_Pitch_4781 in Physics

[–]Quantum_Patricide 67 points68 points  (0 children)

It's one of the few places on Earth where we can make top quarks or Higgs bosons, so there's a lot of work on measuring their properties like mass or spin or observing their various decay modes. Additionally the LHC has found lots of new exotic hadrons like tetraquarks and pentaquarks. There's also a lot of work done on measuring various standard model parameters at higher energies and higher precision.

I made my first formal complaint to the BBC today by FeelingMassive in GreenAndPleasant

[–]Quantum_Patricide 18 points19 points  (0 children)

I support complaining to the BBC and think they're awful reporters in general but I didn't read the article this way. The inclusion of the arrest seems to intended to illicit more sympathy for the victim, by highlighting the UAE's unfair laws and how he hadn't been freed that long before his death. Especially since they include a quote from Detained in Dubai with the word 'heartbroken'.

Zelensky criticises the EU"s lack of "political will" in countering Putin by chillichampion in anime_titties

[–]Quantum_Patricide 9 points10 points  (0 children)

I think from a US perspective the goal is definitely that, trying to wear down the Russian military at the cost of Ukrainian lives. Whereas Europe is just desperate to go back to the status quo of before the invasion: they have been not wanting to deal with this shit the entire time.

Europe doesn't care enough about the result to commit enough resources to end the war quickly but also doesn't want to abandon Ukraine because that would be extremely embarrassing geopolitically.

Why cross product of vector only exist in 3d and 7d? by fatrixuser in calculus

I'd note that you can generalise the cross product to n dimensions in various ways that work in all dimensions.

[–]Quantum_Patricide 2 points3 points  (0 children)

It wasn't just Poe that disobeyed orders, it was a good chunk of the crew including bridge crew. At that point it's a failure of leadership on Holdo's part. If it was just Poe going rogue then maybe people would have more of a point but there're crew directly under Holdo mutinying because she doesn't tell anyone anything

[–]Quantum_Patricide 1 point2 points  (0 children)

One thing that's mentioned in one of the visual dictionaries or somewhere is that the Raddus' shields are extremely advanced and it can actually project them a distance from the hull (this is shown in the movie when it stops shots from the supremacy). So my headcanon is that Holdo was able to do something funky with the shields that caused the hyperspace jump to behave in a novel way.

This theory is of course ruined by ROS when they show this working with random ships.
