What you’re saying is very important: the fact that spins are independent means there is no best time to place a bet, the roulette wheel really doesn't care if you wait three hours before making your next bet. Furthermore, betting on multiple numbers simultaneously is really just a concept in...

I agree; furthermore, we should treat models courteously simply to maintain that habit, since if we are disrespectful to a machine all day long, it is quite likely we will carry that same behavior over into the rest of our time.

Could you explain why you don't see those concepts as related in this discussion? Are you saying that no one used "shut up and calculate" to mean "QM without interpretation"?, or was it that no one who mentioned a "QM textbook" was referring to books on the formalism of QM?

Agreed, and thanks for sharing the information. But you will have noticed that, over the course of this conversation, it doesn't matter who said "Shut up and calculate" or what they meant by it. We are using "Shut up and calculate" to refer to "the formalism", "the textbook", QM without...

I still think that "shut up and calculate", following the language analogy, is more akin to communicating through noises and gestures than to English.

To me, the formalism is fine if all you expect from QM is to calculate what happens in a very small regime of reality. But the formalism itself doesn't tell us how QM is reconciled with GR.

A quantum object is a physical-mathematical object. It is a physical object for which we have mathematical descriptions. It differs from other physical-mathematical objects (such as classical objects) in that, to determine its evolution, it is fundamental to take the Uncertainty Principle into...

Imagine two photons entering a beam splitter through the two input ports. If their wavepackets are sufficiently matched in arrival time, frecuency, polarization, spatial mode, then the quantum states associated with the two paths are indistinguishable. In Bohmian mechanics the particle positions...

Following the analogy of languages and interpretations, what does "shut up and calculate" mean to you?

However, what matterwave says is also correct; one way we express that "weirdness" of QM is reflected in that these quantum objects evolve in a Hilbert space, not in a 3+1 dimensional one.

I insist, call me 2. https://en.wikipedia.org/wiki/Number, "A number is a mathematical object used to count, measure, order and label"

You can also call me 2 instead of javisot, if you prefer.

In this sense, numbers exist just as a person's name exists. Among their functions, in addition to being abstractions of quantity, they also serve as simple labels.
