Interpretations, urban legends, and Hawking

Click For Summary

Discussion Overview

The discussion revolves around interpretations of quantum mechanics, particularly in relation to a quote attributed to Stephen Hawking regarding Schrödinger's cat. Participants explore the origins of the quote, its implications, and the broader context of quantum mechanics versus classical interpretations.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants highlight a quote from Hawking that references Schrödinger's cat, suggesting a dismissive attitude towards interpretations of quantum mechanics.
  • Others correct the attribution of a phrase to Goering, asserting that it originates from a German play, raising questions about whether Hawking was aware of this.
  • A participant shares a recent experiment involving the measurement of a single helium atom, expressing confusion about its implications for wave-particle duality and referencing the concept of delayed choice.
  • Concerns are raised about the applicability of quantum mechanics to classical systems, with one participant contrasting the behavior of helium atoms with that of macroscopic objects like crickets and questioning the deterministic nature of classical laws in chemical reactions.
  • There is a suggestion that some may prefer to focus on calculations rather than engage in philosophical debates about interpretations.

Areas of Agreement / Disagreement

Participants express differing views on the relevance and interpretation of quantum mechanics, with no consensus reached on the implications of Hawking's quote or the nature of quantum phenomena compared to classical mechanics.

Contextual Notes

Participants discuss various interpretations and historical contexts without resolving the complexities of quantum mechanics versus classical interpretations. The discussion reflects a mix of technical and philosophical perspectives.

Who May Find This Useful

This discussion may be of interest to those exploring the philosophical implications of quantum mechanics, as well as individuals curious about the historical context of scientific quotes and the relationship between quantum and classical physics.

"Yeah, well, there are some people who spend an awful lot of time talking about the interpretation of quantum mechanics. My attitude -- I would paraphrase Goering -- is that when I hear of Schrödinger's cat, I reach for my gun."

-- Hawking in the book "The Whole Shebang"

Except that Goering never said that. The phrase comes from a German play of the early 1930s, not from Goering.

but it is a quote of Hawking :-)

A question about the history here... Did Hawking know Goering didn't really say that? Or was he suckered by an urban legend?

The line in Schlageter's play was actually "Wenn ich Kultur höre ... entsichere ich meinen Browning!" "Whenever I hear of culture... I ready my Browning [pistol]", and it has been spawning imaginative memes for the best part of a century now.

I just read a description of the experiment reported several months ago at the Australian national University where they isolated a SINGLE helium atom (really? I am a simple chemical engineer not a physicist) and performed two measurements on it - is it a wave or particle? All as Niels told us. Plus the result was affected retrospectively - delayed choice. So I agree with "when I hear of Schrödinger's cat, I reach for my gun" except I read something else or change the TV channel.
Except I am pretty sure that
(1) a cricket (baseball) does not behave like a helium atom (*)
(2) the far side of the moon exists right now and did not come into existence during the Apollo 8 mission and then disappear again
(3) The Newtonian-based laws that I used for fluid flow, heat transfer etc. etc. seemed to work OK during my career
(4) Chemical reactions carried out in bulk can be safely carried out using deterministic "laws". A certain concentration of reactants given a temperature-time profile with a certain catalyst will produce ammonia (for example) at a known rate and concentration.
I could go on
(*) or could it explain the woeful performances of the England football(soccer), cricket and rugby teams.

Should we all just Shut Up and Calculate or in my case, let someone do that while I use my computer?
