    Is the quantum wave function a real object or a mathematical tool?

    The OP clearly confuses these. Elements of reality is a new topic IMO.

    Is the quantum wave function a real object or a mathematical tool?

    An element of reality isn’t an object either, right? Physics is a human activity. Humans use tools to do physics. These tools include devices we fabricate as well as intellectual tools like mathematics. Fragments of intellectual tools aren’t objects in the usual sense of object. A brick on my...

    Is the quantum wave function a real object or a mathematical tool?

    Yeah, in multiple editing passes I added “object” to side step your double meaning style reply. In retrospect “is the number ##3+i1## a real object” would have been a more complete safe guard.

    Is the quantum wave function a real object or a mathematical tool?

    Hum, is the number 3 a real object? I would say no but that’s just me.

    High School This One Moved Me

    I view mathematics as a rather substantial collection of intellectual tools. Looking at a problem and selecting a 3d tool when a 4d one was more appropriate is just being a poor mechanic. Both are valid tools but only one of them fits the circumstance. The thing about developing mathematical...

    High School Gravitons/Gravity passing through objects

    In physics, particle is a technical term used in quantum field theory so it’s mostly beyond the level of this thread. All particles have energy, momentum and an intrinsic angular momentum called spin. Spin can only be 0, 1/2, 1, 3/2, 2 and so on. Particles arise from quantum fields which, at...

    High School This One Moved Me

    I would say (imo) no. But, geometry is definitely an approximation or idealization of what we see in nature. Developing the logical consequences of these idealizations is what mathematics is.

    Undergrad What are the speed limits of a maglev track?

    Rapidly changing magnetic fields in electrically conductive materials generate what are called eddy currents. Eddy currents are an energy loss mechanism that will increase as the train car moves faster relative to the track. There will be limits imposed by this effect. It may or may not be a...

    High School Gravitons/Gravity passing through objects

    The graviton (at least initially) is an idea that stems from applying local quantum field theory techniques to linearized GR. The resulting attempt only provides answers to first order questions. Feynman wrote a book on this subject you might find interesting.

    Graduate Running lattice QCD on Apple Silicon with native Metal GPU

    Why is the GitHub link redacted? Are there references to published work on your code?

    Graduate Quaternionic Rays instead of Complex

    Yes, I purchased this text quite some time ago and put it down when it became apparent the concept was a wash. As to Adler referencing Trifonov's work, this would require a causality violation. Trifonov references Adler. One is reminded that while all physics is mathematics, not all mathematics...

    Graduate Quaternionic Rays instead of Complex

    Adler wrote a book, "Quaternionic Quantum Mechanics and Quantum Fields." Any overlap with Trifonov? It's a big book I haven't spent much effort on. Trifonov doesn't appear in Adler's references.

    High School Knowledge and information in the physical world

    If that's your question then, yes. Quantum objects don't hold information that determines the outcome of the interaction was my test assertion. A possible counter example is given by entangled particles. Entangled particles occupy a multi particle state which correlate their subsequent...

    High School Knowledge and information in the physical world

    So, if I said the answer is no, could you provide a counter example?

    High School Knowledge and information in the physical world

    What's a "physical participant" in a quantum interaction? As far as I know, and this may not be very far, the basic rules of QM provide no information as to when a given isolated atom or nucleus will decay. It only provides decay rates of collections of such systems. So, is there a means for...
