Quantum Mechanics 100 year anniversary

Click For Summary

Discussion Overview

The discussion revolves around the history and development of quantum mechanics (QM), particularly in the context of its 100-year anniversary. Participants share perspectives on the significance of QM in relation to cosmology and its historical milestones.

Discussion Character

  • Exploratory, Historical, Debate/contested

Main Points Raised

  • One participant shares a link to an article that provides a historical overview of QM, suggesting it is accessible for those informed in science but not experts.
  • Another participant questions the categorization of the thread, indicating that QM is relevant to cosmology and expressing a desire to keep the discussion within that context.
  • A participant corrects themselves regarding the categorization of the thread, acknowledging the relevance of QM to cosmological discourse.
  • One participant notes that quantum theory is approximately 88 years old, referencing Heisenberg's work on the harmonic oscillator and distinguishing between "old quantum theory" and "modern quantum mechanics." They highlight the significance of the Bohr-Sommerfeld model in the current celebration.

Areas of Agreement / Disagreement

Participants express differing views on the relevance of QM to cosmology, with some supporting the connection while others focus on the historical aspects of QM itself. There is no consensus on the categorization of the discussion.

Contextual Notes

Participants reference specific historical milestones and models in QM, but there are unresolved distinctions between "old" and "modern" quantum mechanics, as well as the implications of these distinctions for the current celebration.

It has been 50 years since I was taught or introduced to QM at the end of my EE degree. This article gives the best understandable history describing QM I can remember. It is written for someone informed in science but not an expert.

I found it refreshing as perhaps others here would also

Cosmology? Looks like quantum physics to me - moved.
 
I understand your thinking to move this from cosmology to this location. Cosmology includes QM explanations and my interest is keeping up with cosmology so I posted there. I thought it was useful to cosmological discourse. I stand corrected - thanks
 
Quantum theory is a bit younger, namely about 88 years old. It has been found (for the case of the harmonic oscillator) by Heisenberg in the summer of 1925, when he was recovering from an attack of hay fever on Helgoland.

What we celebrate this year is the Bohr-Sommerfeld model of the socalled "old quantum theory", which was immediately outdated with the advent of "modern quantum mechanics".
