Can we derive quantification of energy mathematically?

Click For Summary

Discussion Overview

The discussion revolves around the mathematical derivation of energy quantification, particularly in the context of modern physics concepts such as the ultraviolet catastrophe and the equipartition theorem. Participants explore various aspects of energy quantization, including its implications in quantum mechanics and classical systems.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions whether the equipartition theorem can be used to derive energy quantification, suggesting that it may not be applicable for high frequencies in blackbody emissions.
  • Another participant notes that quantization of energy is evident when solving Schrödinger's equation, implying a connection to the professor's earlier comments.
  • A question is raised about whether resonance in classical mechanical or electrical systems can be considered a form of energy quantization.
  • A response clarifies that resonance relates to energy transfer rather than quantization, indicating that systems can possess any energy value.
  • One participant draws an analogy between atomic spectra and the ringing of a bell, seeking further clarification on this comparison.
  • A later post expresses appreciation for the beauty and depth of the topic, suggesting that understanding the reasons behind quantization is a complex journey.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between resonance and energy quantization, with some asserting that they are not the same, while others explore the analogy without reaching a consensus on its validity.

Contextual Notes

The discussion includes assumptions about the applicability of the equipartition theorem and the interpretation of resonance, which remain unresolved. There is also a lack of clarity regarding the specific hypotheses mentioned by the professor.

Who May Find This Useful

This discussion may be of interest to students studying modern physics, particularly those exploring concepts of energy quantization, resonance, and the implications of quantum mechanics.

I'm studying for my introduction to modern physics exam, and reading about the ultraviolet catastrophe and why equipartition theorem stops working to explain blackbody emissions for high frequencies I was thinking if we could use the theorem to arrive at the quantification of energy (probably the answer is no).

I remember my professor saying that at some point we'll learn how we can arrive at the quantification of energy from some hypotheses, but I don't remember what that was.

Thanks!

Quantization of energy appears when you solve Schrödinger's equation in many problems We can only guess at what your professor was thinking, but there's a fair chance that that's what it was.
 
Is it correct to say resonance in a classical mechanical or electrical system is quantisation of energy?

You're right, Thank you!

No. The system can have any value of energy. Resonances are related to the transfer of energy, not it's amount.
 
Makes sense, I have always held the analogy when looking at atomic spectra as that of striking a bell with a hammer and looking at the non transient part of the ringing bell's frequency spectrum.

Can you help with the analogy if it is not OT.
 
Its deep, beautiful and powerful:


Mostly it is quantisised but the why will take you on a VERY interesting journey.

Thanks

Unfortunately my phone overheats and shuts down after 20mins of YouTube so yet to watch the second half. That lecturer is a clever, passionate and gentle teacher. Gonna follow his clips.

Thanks for a great link.
