Like.
I am slowly going through the book 'What Is a Quantum Field Theory?' by Michel Talagrand. I came across the following quote: One does... -
Peter Morgan replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.The fundamental principles of QFT, however, include many measurement operators that can be constructed by smearing the measurement...

??? How can the observer's brain solve the Schrödinger equation in real time?

Peter Morgan replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.Put in an extreme instrumental form, I think "The ultimate test for a model is the agreement of its predictions with experiments"...

Peter Morgan reacted to WernerQH's post in the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics with Like.
Do you think that the "basic principles" of quantum theory have reached their final form? I don't. Ballentine's two postulates depend...

More interesting (and applicable to QFT) is the book A. Hobson, Fields and Their Quanta, 2024. It also gives a realist account...

Peter Morgan reacted to PeterDonis's post in the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics with Like.
Yes, that's true, although the way it isn't is somewhat counterintuitive. Spacelike separated measurements can still be correlated...

Peter Morgan replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.But note what I call Hegerfeldt nonlocality, for which I find arXiv:quant-ph/9806036 and arXiv:quant-ph/9809030 helpfully short and...

Peter Morgan reacted to gentzen's post in the thread Undergrad A very interesting paper on orthodox quantum mechanics with Like.
There is a Q&A at the end, starting at 49:19, which contains stuff not contained in that transcript. Below, I collected how I tried to...

Peter Morgan posted the thread Undergrad A Dataset & Signal Analysis Interpretation of Quantum Mechanics in Quantum Interpretations and Foundations.On May 18th, I presented a Colloquium for the School of Engineering and Physical Sciences at North South University, Dhaka, Bangladesh...

Peter Morgan reacted to PeterDonis's post in the thread Undergrad Question about discussions around quantum interpretations with Like.
This is phrased rather confusingly. What you mean is that non-relativistic QM is wrong. But I don't think the OP means to restrict...

Peter Morgan reacted to Lord Jestocost's post in the thread Undergrad A very interesting paper on orthodox quantum mechanics with Like.
Regarding the quote from the conclusion of G. Beck's paper "How to be an orthodox quantum mechanic" (https://arxiv.org/abs/2504.20597)...

Peter Morgan replied to the thread Undergrad A very interesting paper on orthodox quantum mechanics.Thank you. I didn't have a copy of Ballentine available yesterday. I associate a focus on preparation as distinct from measurement...

In his textbook, he gives basically the same description you quoted, but he also says that an equivalent way of looking at the quantum...

Peter Morgan replied to the thread Undergrad A very interesting paper on orthodox quantum mechanics.Apologies, I hadn't understood you to be espousing a minimal statistical Interpretation different from that of Ballentine. What you...
