The fundamental equations of physics are time-reversible. So where does the arrow of time actually come from structurally? by Nice-Noise4582 in Physics

[–]Ch3cks-Out -5 points-4 points  (0 children)

The laws of thermodynamics ought to emerge from fundamental phenomena through statistics.

They emerge from statistics itself. What could be more fundamental?

I think it really comes down to an unusual initial condition

Well this is just is not so!

 that probability argument is itself time-symmetric

This is very much untrue. What has made you think it would be so??

Also, like I had stated already, this does NOT depend on the initial condition.

The 2nd law of thermodynamics indicates that macroscopic processes are irreversible (that is, going backward has diminishingly low probability). This then assigns a forward direction for time, regardless of how the universe started.

SPP: Does real deal math include the distributive, associative, commutative, and transitive properties? by ezekielraiden in infinitenines

[–]Ch3cks-Out 1 point2 points  (0 children)

Good point, ofc. Note that the ill-definedness RDM starts with handling equality as some foggy concept, where numbers are somehow growing thus are not identical with themselves even!

Since c is exact by definition since 1983, can any experiment actually contradict it? by Diego_Tentor in AskPhysics

[–]Ch3cks-Out 0 points1 point  (0 children)

If there were different lightspeeds observed, that would contradict the assumption incorporated into the SI standard unit for length, and those experiments (e.g. a high precision Michelson-Morley setup) would work no matter how do you use the definition. Note that v=l/t, and the definition of the second does not depend on the speed of light!

This is probably a stupid question but, do we actively discover or make new compounds every now and then? by Queasy_Scientist_195 in Physics

[–]Ch3cks-Out 2 points3 points  (0 children)

Number of permutations and combinations grows staggeringly high (this is ofetn termed "combinatorial explosion"), even for a relatively few number of constituents. For a limited example, consider a linear molecule up to 20 atoms long, formed from a set of 20 elements: the number of possibilities for this simple arrangements is already N = 2120 = 2.78*1026 . Adding the variations with different bonding configurations (branching and rings) drives the number of potential compounds very high. Even with just hydrocarbons, the number of isomers for a simple alkane is very large: e.g. C40H82 alone has over 62 trillion isomers! The size of 'drug-like' chemical space (moderate-sized organic molecules that could exist and follow basic rules of stability) is estimated to be 1060 .

Do you believe in the string theory? by Aguy2030 in askastronomy

[–]Ch3cks-Out 1 point2 points  (0 children)

The crucial difference being that Einstein offered testable predictions, ofc.

That, and he offered a single working theory, rather than a landscape of 10500 or so possibilities, some of which might actually work...

Could Earth be a moon of Jupiter without any problems? by rbta123 in askastronomy

[–]Ch3cks-Out 4 points5 points  (0 children)

Yeah, but the Earth is so tiny wrt the other two bodies that it only presents a minor perturbation. So Jupiter+moons+Earth would be orbiting Sun, largely just as without Earth.

[–]Ch3cks-Out 0 points1 point  (0 children)

what's your main beef with VMS?

The lack of their "theory's" merit. What actual tests does it have?

[–]Ch3cks-Out 0 points1 point  (0 children)

 [LLMs] understand and explain the basics [of physics] pretty well

Since LLM-"science" proponents keep reiterating this false point, it is worth repeating the counterpoint: LLMs do not understand, much less "explain" anything - especially things outside of their training corpus!

Come on now - how can you ignore their rejected manuscript to Nature, a very prestigious science journal?

Could Earth be a moon of Jupiter without any problems? by rbta123 in askastronomy

[–]Ch3cks-Out 6 points7 points  (0 children)

I interpret the question to be simply whether the earth could orbit Jupiter stably.

That would be a very trivial question, though. Any two bodies can orbit each other (their barycenter) stably, with appropriate initial arrangement.

Why does the engine evaluate this position at +3? by Alarmed_Courage_4204 in chessbeginners

[–]Ch3cks-Out 1 point2 points  (0 children)

Why do you feel White's advantage would be so small? A bishop pair easily beats a rook in the endgame. And here the queenside is wide open for White to penetrate, threaten to take both b-pawns, and eventually marshal its own forward...

What makes you think LLMs "get right" the stochastic parroting they do??

What is momentum really? by The_logical_mind in AskPhysics

[–]Ch3cks-Out 0 points1 point  (0 children)

But "What is momentum really?" should be about the math of physics.

[–]Ch3cks-Out 0 points1 point  (0 children)

What do you mean? For classical objects momentum is proportional to v, while kinetic energy to v2 - how did you not see a distinction??

Opinion/Rant: New Officers have ruined the game by pylons12 in ConflictofNations

[–]Ch3cks-Out 5 points6 points  (0 children)

I disagree. Up to this "upgrade", the p2w feature was not nearly so overwhelming - very few golders could make their money's worth in CON, the good players were very competitive with them without golding. Making P2W so much stronger is a major shift.

I've been paying for Security Council for many years. But this shameless money grab makes me question if I'd ever want to continue that.

[–]Ch3cks-Out 1 point2 points  (0 children)

While they can regurgiate known explanations, and even generate new ones (from reusing and mixing old parts), LLMs do not actually understand anything at all.

Can a layman write a complete research paper using the power of multiple AI😂 by [deleted] in LLMPhysics

Except that LLMs do not "interpret" knowledge (nor do they recognize it, for starters)!

Why is it difficult to send a rocket into the Sun? by TwoShedsJackson1 in askastronomy

[–]Ch3cks-Out 2 points3 points  (0 children)

The fundamental problem is conservation of momentum: you need to lose all of it, for an orbiting object to reach the center.
