Demystifier's latest activity
-
Demystifier replied to the thread I Entropy and configurations of microstates.Here it is tacitly assumed that ##x\gg n##. Under this approximation $$x(x-1)(x-2)....(x-(n-1)) \approx x^n$$ -
Demystifier reacted to Morbert's post in the thread I Violation of Bell Inequality with unentangled photons with
Like.
As an aside: When we write Bell states like $$\ket{\psi} = \frac{1}{\sqrt{2}}(\ket{\uparrow}_1\ket{\downarrow}_2 +... -
Demystifier replied to the thread I Violation of Bell Inequality with unentangled photons.Not at all, it works for particles which are distinguishable. For example, one particle can be a hydrogen atom made of a proton and an...

Demystifier replied to the thread I Violation of Bell Inequality with unentangled photons.Let me give a simple explanation how is symmetrization (or anti-symmetrization) due to indistinguishability of particles different from...

Demystifier reacted to annuhere3's post in the thread Other Collection of Free Online Physics Books and Lecture Notes (Part 2) with
Agree.
Dommelen’s Quantum Mechanics for Engineers starts with special relativity because quantum theory must stay consistent at high speeds—SR... -
Demystifier replied to the thread What should I do if I found a paper with same result as mine?.Not necessarily. https://en.wikipedia.org/wiki/Stigler%27s_law_of_eponymy
-
Demystifier reacted to Dale's post in the thread What should I do if I found a paper with same result as mine? with Like.
They will. Does your paper provide something that the first one does not? If so, you should cite the first paper in your introduction...

Demystifier replied to the thread I Violation of Bell Inequality with unentangled photons.Another paper appeared today arguing that it's just postselection. https://arxiv.org/abs/2509.03127

Demystifier reacted to pines-demon's post in the thread Predictions for the Nobel Prize in Physics 2025 with Like.
Similar to the 2024 thread, here I start the 2025 thread. As always it is getting increasingly difficult to predict, so I will make a...

Depends what you mean. Classically, gravitational collapse leads to a singularity. There isn't any matter inside the hole once the...
-
TIL that there are at least 10 ways of saying "I can't" in Finnish: 1. En osaa - due to lack of knowledge or skill. Such as, I can't...

Demystifier reacted to martinbn's post in the thread I Violation of Bell Inequality with unentangled photons with Agree.
Doesn't this depend on which degrees of freedom you use? If you choose two random photons and ignore all but their polarizations, they...
-
Demystifier replied to the thread I Why work is PdV and not (P+dP)dV in an isothermal process?.Exactly! You should learn it first.

Demystifier replied to the thread Today I Learned.Which part was new to you? :oldbiggrin:
-
Recently I learned about the Standard Model Lagrangian.
