Talk:How things work college course/Quantum mechanics timeline

From Wikiversity
Jump to navigation Jump to search

I wrote this timeline for a conceptual college course that some people used to call "Physics for Poets" (analogous to Geologoy as "Rocks for Jocks" and Chemistry as "Chemistry for Cooks". But with today's ridiculously high tuition rates (something Wikiversity will someday fix with open source learning), students are offered the more practical sounding "How Things Work".

I had been meaning to simplify this timeline when a fellow Wikiversarian added a mathematical discussion of uncertainty and wavepackets. Not to worry. I am delighted that someone wanted to strengthen this timeline with mathematical rigor. Both timelines are a great improvement over the dreary and detailed w:Timeline_of_quantum_mechanics hosted by Wikipedia.

I don't need this resource until August 2014, so don't expect much progress till summer. --guyvan52 (discusscontribs) 02:25, 9 November 2014 (UTC)[reply]

Text comments:

Combining this with "Abridged timeline of quantum mechanics" may make a better submission. --Marshallsumter (discusscontribs) 16:58, 5 May 2017 (UTC)[reply]

Review for WJS contains a description of what Planck did and was doing. Boltzmann's approach could be thought of as atoms emitting quantized energy or photons. --Marshallsumter (discusscontribs) 00:22, 2 July 2017 (UTC)[reply]

Include the reference "J.S. Bell, On the Einstein Podolsky Rosen Paradox, Physics, 1:3 195-200, 1964." here in Recent advances.

References 7 & 15 are identical. --Marshallsumter (discusscontribs) 14:20, 3 July 2017 (UTC)[reply]
