Angular Momentum & Plank's Constant

In summary, there is a paper claiming that Plank's Constant exists due to the conservation of classical angular momentum. The link to the paper is provided and the opinion is requested. The paper is considered to be speculative and the journal is deemed to be unreliable. A specific part of the paper is mentioned and compared to the conservation of energy. The idea of the electron's orbit being a hollow, rotating torus is also questioned. The stability of the electron's orbit is explained through de Broglie matter wave and the time-independent Schrodinger Equation. However, there may be more to the paper that is not understood.

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.

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 Schrodinger Equation for the Coulomb potential has standing wave solutions. But hey, maybe there's something here I'm not understanding.
 

FAQ: Angular Momentum & Plank's Constant

What is Angular Momentum?

Angular momentum is a physical quantity that measures the amount of rotational motion an object possesses. It is defined as the product of an object's moment of inertia and its angular velocity.

How is Angular Momentum related to Plank's Constant?

Angular momentum is related to Plank's constant through the quantum mechanical principle of angular momentum quantization. This principle states that angular momentum can only exist in discrete, quantized values, and Plank's constant is the fundamental constant that governs this quantization.

What is the significance of Plank's Constant?

Plank's constant, denoted as h, is a fundamental constant in quantum mechanics that relates the energy of a photon to its frequency. It is significant because it provides a link between classical mechanics and quantum mechanics and helps explain certain phenomena that cannot be explained by classical physics.

How is Plank's Constant calculated?

Plank's constant is a physical constant that is determined experimentally. It is calculated by measuring the energy and frequency of a photon and using the equation E=hf, where E is the energy, h is Plank's constant, and f is the frequency.

What are some real-world applications of Angular Momentum and Plank's Constant?

Angular momentum and Plank's constant have various applications in modern technology, including quantum computing, atomic and molecular spectroscopy, and particle accelerators. They are also used in the development of new materials and technologies, such as LED lights and solar cells.
