Discussion Overview

The discussion revolves around the phrase "shut up and calculate" in the context of quantum mechanics (QM) interpretations. Participants explore its origins, implications, and the philosophical versus technical approaches to QM, without reaching a consensus on its association with specific interpretations or its validity in scientific discourse.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants suggest that the phrase is attributed to David Mermin, relating it to the Copenhagen interpretation of QM.
  • Others recall that the phrase has been used by various lecturers and is seen as a reflection of a technical approach to QM, where calculations take precedence over interpretations.
  • There is a discussion about whether "shut up and calculate" conflicts with any experiments, with some asserting that it does not, as it avoids addressing the conceptual foundations of QM.
  • One participant notes that the phrase implies a certain interpretation or deeper understanding, suggesting a connection to Bohmian mechanics through the notion of deterministic evolution of the wave function.
  • Another participant questions the existence of a "deeper level" of understanding in QM, highlighting the enigmatic nature of the theory.
  • There is a mention of hidden variables, specifically particle trajectories, as a potential aspect of the Bohmian interpretation that could be calculated.

Areas of Agreement / Disagreement

Participants express differing views on the implications of "shut up and calculate," with some arguing it is a purely technical approach while others believe it suggests deeper interpretations. No consensus is reached regarding its association with specific interpretations or its philosophical implications.

Contextual Notes

Some participants note that the phrase may not be associated with the Bohmian approach, while others argue it could be due to its focus on calculable quantities. The discussion reflects varying interpretations and assumptions about the phrase's meaning and implications in the context of quantum mechanics.

I'm looking for the source for the QM interpretation of "shut up and calculate". I thought it was synonymous with the Bohm theory and that I had seen it in Shankar or Sakurai.

Yes, I Googled it and found David Mermin, and some other dude named Tegmark that I'm won't to bring up lest I incur the wrath of the Mentors. Point is, don't tell me "google it".

I'm pretty sure it's Mermin. It was a comment about what the Copenhagen interpretation is suggesting.

I remember my QM lecturer has also used this famous quote himself, along with the statement that there is not much else to do in QM anyway.

So what are the problems with "Shut up and calculate" (ShUAC)? Does it disagree with any experiments? (Other than EPR, of course.) Citations would be appreciated.
 
I've explicitly asked Mermin to incant the phrase to me on occasion; he's a cool guy :)

Anyways, it doesn't disagree with any experiment. Why would it? It simply remains quiet about the conceptual foundations of QM. The problem with this of course is if one wants to go beyond calculations and actually understand the theory at a deeper level then one must investigate the conceptual foundations and "shut up and calculate" isn't too great for that :)

Of course it does not disagree with experiments; the quote essentially just refers to the fact that most scientist who use QM do not really care about interpretations of QM (or perhaps just don't see interpretations as being a scientific question).

It is an purely "technical" approach to science.

Although this of course only works if there really IS such a thing as a deeper level...

That's a fair point! QM is quite the enigma.

Can you get Mermin to chant it Gregorian style and post in on youtube. Also, tell him to fix the factor 2 error in his solid state book's derivation of the Drude model.

I think does ShUAC does imply an interpretation/deeper understanding. I.e. any "measurement" has to be treated as a potential acting on psi. Which in turns implies deterministic evolution of psi which sound notoriously Bohmian.

I've found myself in a similar mentality. I've stopped bothering to think about what QM really means when I am presented with QMechanical Problems. Although I do like to ponder on the philosophical side of QM, but only in the quiet Sunday evenings.

RigetFrog, shut up and calculate is usually NOT associated with the Bohmian approach.

But perhaps it should be, because it seems to be the only interpretation which proposes a new quantity to be actually calculated.

I don't understand. You mean hidden variables? Please elaborate.

I mean particle trajectories, which of course are hidden variables.
