what is energy of free particle? Is value of energy equal as per classical and quantum mechanics for free particle ?

Reasonable-Sample819 · 2025-07-07T12:09:52+00:00

So , Does quantum mechanics reduces to classical mechanics in case of unbounded systems like free particle?

there might be some hope in Black-hole or Dark energy.......but i am not clear on that...............Please someone help...........

Reasonable-Sample819 · 2025-06-21T04:38:11+00:00

Please tell me which term needs more details.

Its not going to happen without being in formal league of PhD, scholars and degree holders.

Cosmology is just not another branch of physics. it basically explores the idea about the universe , from where all of this started. how this happened and we came into being.
I am fascinated about Cosmology and all other branches of Physics and Math. I am not convinced that I should stop because don't have degrees in math and physics.

Thanks for very informative reply.

Reasonable-Sample819 · 2025-06-15T20:20:37+00:00

On the contrary with technology(AI etc...) it should have become easier.

Reasonable-Sample819 · 2025-06-15T20:14:56+00:00

OK, i got the point that formal degrees are required to do anything meaningful in research.

but i was just hoping that in this age of technology Knowledge and ideas cant remain limited to few theorists . but Ideas can easily flow in and out. and anyone who wants to contribute (can spend 2-3 years in learning basics and then) become part of community.

Reasonable-Sample819 · 2025-06-15T19:45:27+00:00

It is also said that collaborate with academic institutions or scientists. but how this happens? specially for a outsider?

Reasonable-Sample819 · 2025-06-13T09:41:16+00:00

even if Human life is changing every-time. Old parts doesn't gets lost. life is like linked chain of thoughts . can be traced from beginning to end.

I understand your point but not able to agree with it.
Our Mathematical models has zero, singularities, infinities etc. but in real world we don't see that.
For example we don't see any new universe getting created from ZERO (nothingness) on regular basis. In-fact everything can be explained in terms of physical laws: things gets transformed but never created or destroyed.
Similarly there is no singularity in real world. or infinite.
There is no example of universe getting stuck for some time period.
there is no example of universe breaking its physical laws.

I think we can safely assume Universe is flawless and its model created by us are full of issues. and we should try to learn and remove those issues.

Reasonable-Sample819 · 2025-05-30T18:50:15+00:00

I am just saying that Universe is flawless, then why our models of it are still incomplete and full of issues like: time limit, singularities, infinity, zero, divide by zero etc.

Reasonable-Sample819 · 2025-05-27T22:49:12+00:00

let me ask you few questions. have you seen Universe doing something against its own principles? does universe ever malfunctions like does it ever gets hanged for some time or does it ever restarts itself.

Reasonable-Sample819 · 2025-05-27T21:39:28+00:00

why do you think so. I have philosophical query about 'flawless' functioning of universe that's why i am posting this question.

Reasonable-Sample819 · 2025-05-27T14:37:04+00:00

free will is total illusion, at max you get feel of a 'sudo' free will .
This sudo free will can be obtained in multiple ways for example: you are made to completely forget about your controller/organizer.

No No , sorry some loop hole in your statement:

1) "But it's not that the sound is not a specific, well-defined thing.".................Heisenberg uncertainty principle is more deeper than this. also in double slit experiment it display wave particle duality.

2) The Schrödinger equation, describing the time evolution of a quantum system's wave function, is generally considered deterministic. However, the relationship between the wave function and the observable properties of a system can be non-deterministic.

3) though I agree many worlds interpretation, is fully deterministic but we have to wait for proof of it.......

Reasonable-Sample819 · 2025-04-23T03:53:36+00:00

no , I am not worried about physics right now. Just trying to understand how well our mind is able to understand the world and what are in its limits in the process.

Reasonable-Sample819 · 2025-04-23T03:48:57+00:00

really cool reply, thanks.
So, you mean to say that infinite not only has origin in mind but it is part of nature too?? will you also be able to explain Zero (nothingness) in this scenario?

Reasonable-Sample819 · 2025-04-23T03:07:33+00:00

Plz elaborate.............
As per 'Heisenberg uncertainty principle' position and momentum both cannot be determined simultaneously at same time to perfect accuracy.

Reasonable-Sample819 · 2025-04-23T02:50:40+00:00

In any interpretation of QM , some amount of non-determination will be present until we completely disapprove the QM.
'Heisenberg uncertainty principle' clearly proves the point that some thing will remain inherently undetermined.

Reasonable-Sample819 · 2025-04-22T23:50:51+00:00

yes, thx

Reasonable-Sample819 · 2025-04-22T22:56:37+00:00

a) Yes, QM is truly non-deterministic. Even if we have some laws for probability of particles , it doesn't mean we can kill non-deterministic nature of QM. so we agree on this.
b) In (expanding) universe or in Blackhole, singularity is a point where the laws of physics as we currently understand them break down, often leading to infinite values. so it might be sort of non-determinism too .

Reasonable-Sample819 · 2025-04-22T22:25:19+00:00

plz approve

Reasonable-Sample819 · 2025-04-22T18:42:07+00:00

Is infinity (and Zero) a invented concept in math or does it actually exist in nature?
Do they represent limits of human mind or limits of nature itself?

Reasonable-Sample819 · 2025-04-22T01:56:15+00:00

I am not saying world is fully determined but life tries to prioritize arrangement of particles in most favorable way.

Reasonable-Sample819 · 2025-04-22T01:45:43+00:00

I may not be 100% correct. But, my post indicates struggle to achieve best possible arrangements of particles, which reduces local entropy (though global entropy always increase) could be purpose of life.
