Generally :up: but watch out for the tendency to reify, 'make into a thing'.
— Wayfarer
Thanks. You have warned me about "reification" before*1. But it seems that most Philosophy-versus- Science arguments, going back to Plato's Idealism, hinge on the Reality (plausibility ; utility ; significance) of abstractions. Are Mathematics and Metaphysics "real" or "ideal"? Regardless of how you categorize them, Ideal or Abstract non-things are very important for philosophical discussions, no?.
Is the Aether, postulated by physicists to explain such ideas as "vacuum energy" real or ideal? Here's what I said about that : "I argue that the metaphysical Aether is immaterial, just like the hypothetical Quantum Vacuum and the Universal Quantum Field. It's not physical or spiritual, but mathematical (statistical) and mental (logical). If Math & Mind are real, so is the statistical sphere of Probability & Potential.". Is "immaterial" the same as non-thing & unreal? Is Math a real thing, or an abstraction in a human mind? Is the Quantum Field*2 a perceivable real thing, or an abstract human concept?
I didn't claim that Aether is an actual physical thing, as some physicists seem to imply*2. Instead, I'm saying that it is the Potential for causal Energy ; which is the Potential for actual Matter*3. So, the philosophical question here seems to be : is Potential to Actual*4 the same as Reification". It seems to "make nothing into a thing". :smile:
*1. Reification means to treat something abstract as if it were a physical thing. For example, you might reify an abstract concept like fear, happiness, or evil.

*2. According to current scientific understanding, quantum fields are considered to be real, existing throughout space and acting as the fundamental building blocks of the universe, with experimental evidence supporting their existence and effects; although they are a theoretical construct, they provide incredibly accurate predictions about the behavior of particles and are considered the best explanation for our physical reality at the subatomic level.

Note --- Is "considered to be real" a fact or a belief? Is a "theoretical construct" a real thing, or a reification?
*3. Yes, "energy is potential for matter" means that energy represents the capacity to do work or cause change in matter, essentially acting as a stored potential that can be released to create movement or transformations within matter; this is often described as potential energy, which is energy stored due to an object's position or state, ready to be converted into kinetic energy (motion) when conditions change.

*4. In Aristotle's philosophy, potentiality is the capacity of something to develop into a specific state or perform a specific function, while actuality is the realization of that capacity. These concepts are central to understanding change and reality, and helped Aristotle explain how things can change while maintaining their identity.

Conceptually, the Schrödinger equation is the quantum counterpart of Newton's second law in classical mechanics. Given a set of known initial conditions, Newton's second law makes a mathematical prediction as to what path a given physical system will take over time. The Schrödinger equation gives the evolution over time of the wave function, the quantum-mechanical characterization of an isolated physical system.
I have mentioned before that fundamentally the S. equation reduces to a simple calculus concept: the instantaneous change in a thing is proportional to the amount of that thing at that time. Think of continuous compounding of interest in the financial realm. Nothing magical. — jgill
The challenge for scientific realism is the concept of superposition — Wayfarer
Quantum superposition is a fundamental principle of quantum mechanics that states that linear combinations of solutions to the Schrödinger equation are also solutions of the Schrödinger equation. This follows from the fact that the Schrödinger equation is a linear differential equation in time and position. More precisely, the state of a system is given by a linear combination of all the eigenfunctions of the Schrödinger equation governing that system.
Yes. The calculation is intentionally deterministic, but when scientists observe (measure) what actually happens, it doesn't make sense*1. Measurement is an attempt to make observations consistent with our expectations. Schrodinger's half-dead Cat is an illustration of the problem of how to interpret the results of calculations that don't conform to our deterministic prejudices.According to John Fernee QM is entirely deterministic (Schrödinger's Wave Equation). Cause and effect. It's in measurement that things seem non-traditional. — jgill
Did scientists "catch god with his pants down", or are they too far from the measured "forest" (quantum field) to clearly see the statistical "trees" (fluid/solid wavicles)? Unlike yes/no mathematics, probabilistic Statistics must be interpreted in a specific context, and from a personal perspective. Hence, interpretation of meaning is the purview of Philosophy, not Science. :smile:Quantum physics observes what appears to be a statistical "glitch in the matrix" — Gnomon

It's a philosophical question which most philosophers are not equipped to even begin to answer — flannel jesus
Who, then, do you trust to answer "philosophical questions" of meaning? Feynman gave-up on trying to understand quantum reality in non-mathematical terms : "shut-up and calculate". Yet, unlike most American scientists, the European pioneers of quantum physics were trained in both Science and Philosophy*1.It's a philosophical question which most philosophers are not equipped to even begin to answer. Understanding what the mathematical concepts mean at root takes quite a lot of effort and study, and I fear most philosophers want to give their philosophical take on quantum physics without having done the prerequisite work of actually understanding the physics.

*1. Heisenberg later stated that "My mind was formed by studying philosophy, Plato and that sort of thing" and that "Modern physics has definitely decided in favor of Plato. In fact the smallest units of matter are not physical objects in the ordinary sense; they are forms, ideas which can be expressed unambiguously only in mathematical language".

...the inherent difficulties of the materialist theory of the atom, which had become apparent even in the ancient discussions about smallest particles, have also appeared very clearly in the development of physics during the present century.
This difficulty relates to the question whether the smallest units are ordinary physical objects, whether they exist in the same way as stones or flowers. Here, the development of quantum theory...has created a complete change in the situation. The mathematically-formulated laws of quantum theory show clearly that our ordinary intuitive concepts (such as 'it exists' - wf) cannot be unambiguously applied to the smallest particles. All the words or concepts we use to describe ordinary physical objects, such as position, velocity, color, size, and so on, become indefinite and problematic if we try to use them of elementary particles. I cannot enter here into the details of this problem, which has been discussed so frequently in recent years. But it is important to realize that, while the behavior of the smallest particles cannot be unambiguously described in ordinary language, the language of mathematics is still adequate for a clear-cut account of what is going on.
During the coming years, the high-energy accelerators will bring to light many further interesting details about the behavior of elementary particles. But I am inclined to think that the answer just considered to the old philosophical problems will turn out to be final. If this is so, does this answer confirm the views of Democritus or Plato?
I think that on this point modern physics has definitely decided for Plato. For the smallest units of matter are, in fact, not physical objects in the ordinary sense of the word; they are forms, structures or — in Plato's sense — Ideas, which can be unambiguously spoken of only in the language of mathematics. — Werner Heisenberg, The Debate between Plato and Democritus
Quantum fields can be considered ontological, although you aren't compelled to do so.The field is not an ontological concept, but a phenomenological one. If we were as small as a photon, we could formulate an ontology of the very smallest. And only then would there be a unified physical theory. — Wolfgang
Quantum effects have an impact on the macroscopic world, so it can't be ignored.it makes no sense to try to apply quantum mechanics to the macroscopic world — and this also applies to philosophical conclusions. — Wolfgang
There's only one world, and it seems to be fundamentally quantum mechanical (subatomic particles do not behave like classical objects). But there is clearly a disconnect in our ability to describe the macro world in quantum terms. That doesn't disprove reductive physicalism, but it does leave room for one to deny it-perhaps there is ontological emergence.Why don’t classical and quantum physics go together? Are we dealing with two different worlds or are they just two different descriptions? — Wolfgang
