Angular Momentum & Plank's Constant

Click For Summary

Discussion Overview

The discussion revolves around the relationship between angular momentum and Planck's constant, specifically examining a paper that suggests a connection based on the conservation of angular momentum. Participants express skepticism about the paper's claims and explore the implications of its arguments.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant shares a paper claiming that Planck's constant is related to the conservation of angular momentum, inviting opinions on its validity.
  • Another participant dismisses the journal as a "crackpot venue," suggesting a lack of credibility.
  • A different participant expresses reluctance to label the author as a crackpot, suggesting they may not fully understand the topic.
  • Concerns are raised about the paper's assertion that Planck's constant has dimensions of angular momentum, comparing it to a flawed analogy involving torque and energy conservation.
  • One participant argues that the stability of an electron's orbit is due to its nature as a de Broglie matter wave and the solutions to the Schrödinger Equation, rather than the claims made in the paper.

Areas of Agreement / Disagreement

Participants generally express skepticism regarding the claims made in the paper, with multiple competing views on the validity of the author's arguments and the interpretation of angular momentum in relation to Planck's constant. The discussion remains unresolved.

Contextual Notes

Participants highlight potential limitations in the paper's reasoning, including the dependence on specific definitions and the lack of clarity in the relationship between angular momentum and Planck's constant.

I found a paper online that claims that Plank's Constant exists because angular momentum (classical) is conserved. Here is the link for that paper http://www.journaloftheoretics.com/Articles/4-4/Rotor.pdf
I'm interesting in your opinion of the paper. Much appears to be wild speculation. Thanks in advance.
 
Physics news on Phys.org
That "journal" is a crackpot venue.
 
Apparently. Though I wouldn't apply the word crackpot to the author, who appears to honestly not know any better.
 
I haven't read the whole paper yet, but this part sticks out:

"In SI (Système International) units, it has dimensions of angular momentum (kg⋅m2/s). This means that the Planck’s constant h is governed by the law of conservation of angular momentum, one of the main laws of the Nature."

Isn't that like saying that because torque has dimensions equal to the units of energy, it's related to energy conservation?

The whole thing with the electron's orbit looking like a hollow, rotating torus, is also quite suspect. The electron's orbit around a nucleus isn't stable because of the availability of two rotations (whatever that means). It's stable because it exists as a de Broglie matter wave, and because the time-independent Schrödinger Equation for the Coulomb potential has standing wave solutions. But hey, maybe there's something here I'm not understanding.
