Timeline: Original research

The timeline has the look of original research, with almost all of the references being primary (carried to an absurd extreme in the entry for Edward Raymond Andrew). It needs references from secondary sources. RockMagnetist (talk) 09:11, 30 November 2011 (UTC)[reply]

I have moved the timeline to its own article. It was too large to be a table inside another article. RockMagnetist (talk) 18:46, 24 April 2012 (UTC)[reply]

Some of the entries in the timeline are long for a timeline but would make nice additions to this history. RockMagnetist (talk) 21:38, 24 April 2012 (UTC)[reply]

"Heisenberg formulated his uncertainty principle in 1927, and the Copenhagen interpretation started to take shape at about the same time."

Before this statement, the article is good at briefly explaining the nature of things before or around introducing terms for the things. Why he had to, briefly? Did the Copenhagen interpretation depend on this principle, and if it did, then how? If it did not, then the concepts should probably be separated in the text of the article. Thank you. - 89.110.8.145 (talk) 18:41, 15 July 2013 (UTC)[reply]

Overview - Bohr's reluctance

In the second paragraph of the Overview section it reads: "In 1900, the German physicist Max Planck reluctantly introduced the idea that energy is quantized in order to derive a formula [...]" Planck didn't introduce the idea that energy actually was quantized (reluctantly or otherwise). He regarded this as a mathematical trick that happened to lead to a solution of the problem of black body radiation. The idea that energy actually was quantized didn't surface until several years later. Jorgeditor (talk) 14:46, 25 April 2014 (UTC)[reply]

Disagreement

It would be nice with a fuller account of the "debates" about how QM should be formulated in the period 1923-25. The Copenhageners were pretty much disposing of de Broglie as a crank (perhaps rightly so, he had been more than stubborn about a failed idea's validity in related areas (spectroscopy)), The Copenhageners did not like the thought of differential equations governing QM. One of very few taking de Broglie's ideas about particle waves seriously was Einstein. Another one was Schrödinger, who had had similar ideas published already 1921. I've just now learnt this from an entertaining article, Why was it Schrödinger who developed de Broglie's ideas in Historical studies in the physical sciences (can be found in JSTOR).

Better history in Introduction to q.m.

Introduction to quantum mechanics calls this the Main article on history. But it has more complete information. Johnjbarton (talk) 02:04, 30 June 2023 (UTC)[reply]

I have merged the Planck, photoelectric effect, and Bohr atom sections from the Introduction to quantum mechanics into this article. Johnjbarton (talk) 16:19, 7 July 2023 (UTC)[reply]
I merged the remaining core history into this article. Still a lot of clean up is needed.
  • the intro is overgrown,
  • many citations missing
  • missing connections to Bohr-Sommerfeld model
  • Dirac is lonely at the end
  • QED, Willis Lamb not mentioned.
  • Particle physics.
  • Quantum computing.
(These were all issues in the original articles as well). Johnjbarton (talk) 17:02, 7 July 2023 (UTC)[reply]

More random history articles

I stumbled upon Bohr–Sommerfeld model and Old quantum theory. Wonder if there are more.... Johnjbarton (talk) 16:21, 7 July 2023 (UTC)[reply]
