Regardless of philosophical issues, we can in fact experimentally verify, to some reasonable degree of precision, that bowling balls and pool balls both accelerate toward the ground when dropped. If you have philosophical problems with the concept of acceleration, you should separate that from your ability to look at that evidence and see what does, in fact, happen — flannel jesus
Why don't you try answering his question? — tim wood
Assume all of that is done to your satisfaction beyond all reasonable doubt. — EricH
E.g., if I say that I observed an object in a vacuum chamber accelerating towards the center of the earth at 9.8 m/sec**2, I think you would agree that that is a true statement (it corresponds with reality). — EricH
Also, is there a distinction when you put the word in quotes? — EricH
Sorry, I didn't mean "the set of discernment which are not subjective." I meant, "the set of all discernments (which are necessarily made by subjects) is a set, an abstract entity," and abstract entities are generally not considered to be subjective. — Count Timothy von Icarus
For example, we could have the set of all experiences where people experience red. The experiences are subjective, the set is an abstract object. — Count Timothy von Icarus
Right, but the converse is generally not accepted. "If no observer notices something as a difference, then by the very fact that no difference has been noticed as a difference, the difference has, necessarily, made no differences to any observer... and so is not a difference." — Count Timothy von Icarus
Really, I am just looking for a good argument that says "positing inaccessible differences is sort of nonsensical." — Count Timothy von Icarus
Both views lead to coherent accounts, just with different numbers of things in the world.
Unless someone can show how either view leads to contradiction, then the choice is arbitrary, not empirical. — Banno
We're going way off topic here, but when you use the word "truth" are referring to the Correspondence Theory of Truth? — EricH
Since effing when has science ever been "truth-apt"? Where in any edition of the scientific method does "truth" enter in. And another question to you, what is it that you imagine "truth" to be? — tim wood
Metaphysics has been defined as either the study of being, which is the study of nothing at all, because if being has any predicates it ceases to be just being. — tim wood
Cause is so difficult a concept to make rigorous that for a century most of science has dispensed with its use as a meaningful term, except in informal usage where it stands as a shorthand, or in the few areas it may still be used. — tim wood
So just to be clear, you sincerely believe that Einstein (along with the entire scientific community) misinterpreted the results of M-M and are engaging in some form of pseudoscience? — EricH
I'm all done here. — T Clark
The idea is that MU can have his aether - there is no evidence for it - as what he calls metaphysical speculation, and which I disqualify of substance in a scientific discussion. — tim wood
And of course Mickleson-Morley is "pseudoscience" and "blatantly false."
10 hours ago — tim wood
Typical. You're asked three questions, which you ignore. You confuse "forum" with "discussion." And of course Mickleson-Morley is "pseudoscience" and "blatantly false." — tim wood
It's fundamentally different from the aether, because the aether was always understood as an independent, separate substance from the bodies which exist within it. This was the premise of the M-M experiment. Now, respecting the results of M-M, we can either say that this was a misunderstanding of the aether, and produce a new model of the aether which does not have that requirement, or we can insist that "separate substance" is essential to the conception named "aether", and therefore dismiss "aether" as inadequate, and come up with a new word to refer to the medium for light.
Clearly, "field" is inadequate because it represents the medium with random locations, arbitrary points, instead of identifying the true particles which must exist within the medium, comprising the medium, as is required to support the observed wave motion of electromagnetism. Only through identification and modeling of the true particles of the medium can an adequate understanding of it be produced. And according to what M-M indicates (no aether wind), along with what the experiments of quantum field theory indicate, all massive objects must be composed of this same medium. — Metaphysician Undercover
Starting with MIckleson-Morley in 1887, and successive experiments, it has become understood and accepted by anyone with at least a high school, or even junior high school, science class that the aether simply does not exist. And this is the science of the thing. — tim wood
This is unfortunate because, stripped of these connotations, it rather nicely captures the way most physicists actually think about the vacuum. . . .
You're in a science discussion, which you are determined to derail, and your account is just that you're "doing" no science at all, but metaphysical speculation. — tim wood
The fact that light can propagate as a wave through a vacuum with no medium is an established scientific fact — T Clark
It's pseudoscience. — T Clark
Would you say that we should take into account boredom when discussing why a nazi became a nazi? Or would you attribute the joining to a mental weakness that is exploitable by charismatic leaders heading up (not so) righteous causes? Maybe we should consider whether or not they joined because their favorite uncle said he would buy them a case of beer if they did? — ToothyMaw
Phenomena in the world are not constrained to behave in accordance with our definitions. Before Michelson-Morley, people did believe that a medium was required for a wave to propagate. It took them a while to be convinced otherwise. Your definition is 150 years out of date. — T Clark
So the best analogy I can come up with is that photons are particles which also exhibit wave-like behavior. — EricH
By way of background, I'm pointing to the issue of definite descriptions, claiming that the arguments to the effects that one does not need a definite description in order for reference to function are pretty convincing. — Banno
I don't have much background in Aristotle, but suspect that logic has come some way since his time. — Banno
If I believe what I am writing I am not operating on bad faith.
I try my best to explain my reasoning. — NOS4A2
This is not a metaphysical statement. In this context it's a statement about optics, the physics of light, and it's wrong. — T Clark
Again - this statement is at odds with the fundamental basis of modern physics. — T Clark
I agree that a value judgement is an activity, an event. But I’m not talking about a particular value created by such a judgement - a measurement. That is a position in a hierarchical (linear) relation to our momentary involvement in that event. It is not an object. What I’m referring to is qualitative or potential value as variability, not a value as a reductionist relation to intra-action. — Possibility
What I’m saying is we assume that value structures are dependent on the human mind, but this is a misunderstanding. The number is a measurement, a momentary intra-action with value, not value itself. It is the human mind that consists of ongoing value judgement - ongoing relationality to the inherent variability of potential/value. — Possibility
The only requirements for a system are complexity and relationality. — Possibility
Stop trying to anthropomorphise the hurricane. Regardless of our models, a hurricane would not exist without certain intra-acting variables (not particular values), which also determine its duration, movement, intensity, etc. Whether or not anyone cares or understands, these variable aspects of reality are important and significant to the hurricane in its becoming. — Possibility
There is the human mind governed by grammatical logic, and some external system of reality it cannot accurately represent. — Possibility
It’s a refusal to posit and seek to understand a broader relational framework in which two systems can intra-act. — Possibility
I’m suggesting that you consider the possibility that this logical system dictated by grammatical conventions exists in a broader relational framework which includes those aspects of mathematical and scientific findings that appear to contradict within the narrow framework of grammatical logic. Consider the possibility that you’re on the wrong track, if it must stop at dualism. — Possibility
This is completely at odds with the fundamental basis of modern physics. There's no legitimate physicist in the world who believes it. Light propagates without a medium. If you post this on a physics forum, it will be removed immediately. It's pseudoscience. — T Clark
The experiment compared the speed of light in perpendicular directions in an attempt to detect the relative motion of matter through the luminiferous aether ("aether wind"). — Wikipedia - The Michaelson-Morley Experiment
The comparison is an understandable one to bring up, I think, but this answer illuminates what I was saying above: the quantum field(s) being Lorenz invariant makes it fundamentally different from the aether — flannel jesus
But a value judgement is not value as an objective structure of reality. It’s much more complex than this narrowly perceived relation configured as a linear hierarchy or sliding scale. — Possibility
To understand value, we need to take into account the capacity of non-human materiality to contribute to a broader perception of meaning. The oscillation frequency of an electron in a caesium atom matters to us ‘reading’ an atomic clock, but does this matter if no-one is ‘telling’ the time? And isn’t the number we attribute to this frequency just a value judgement - a measurement derived from our collaboration with the materiality of the clock components in ‘telling time’? The notion that meaning and value are structures exclusive to the human mind is symptomatic of grammatical conventions falling behind in understanding our broader relationality with the world. — Possibility
Agency is recognised as a property of the system itself, and these so-called ‘subjects’, ‘actions’ and ‘objects’ are all fundamentally active elements, their apparent ‘properties’ a purposeful configuration of the particular intra-action, within which we should recognise ourselves as necessarily involved. — Possibility
A mind is not required to respond to the variability of value, only to render it as a judgement, an opinion. — Possibility
We can reference God if you’d like, but I would argue that God is not an actual being who makes value judgements, but is the pure, undifferentiated source of logical, qualitative and dynamic relationality, with which all judgements are but a localised (limited) intra-action of perceived meaning. — Possibility
So we understand that what is important to the hurricane are some variables and not others - regardless of how it might be perceived in terms of ‘value’. — Possibility
Then how can you be sure you’re on the right road, or even heading in the right direction? — Possibility
That feeling of ‘repugnance’ is intuition telling you there’s something amiss, but there's no determining from affect alone whether what’s amiss is in what you’re describing or the system you’re using to describe it. And you can only critique the system from outside it. So what are you afraid of? — Possibility
So why cling to the goal? Why not try to understand the complexity as it exists? — Possibility
M-M explicitly disproved that notion. If there was a substance, then M-M would have detected it. That's what eventually led to relativity. If I'm misunderstanding it then please explain. — EricH
Ok, suppose space is the "substance there which is waving". After all, the gravitational wave observations (combined with electromagnetic observations of the source of detected gravitational wave observations) provide some pretty good evidence for space waving. — wonderer1
That some people are highly motivated without feeling duty says nothing about the power of duty, just as the claim that, say, there are more roses in a garden than any other type of flower is not affected by the claim that there are other types of flowers in a garden. That this "garden" could hypothetically have a different composition I grant, but all of the flowers need not be roses for most of them to be. — ToothyMaw
Perhaps I'm misunderstanding you, but the Michelson–Morley experiment disproved that idea. — EricH
I contend that duty is perhaps the single strongest motivator for action I can think of, whether it is duty to the tribe, an ideal, a spouse, etc., and should be nurtured wherever it exists to good ends. — ToothyMaw
Soldiers, office clerks, garbage men, engineers - everyone craves duty, and those who can deliver the correct conditions are the most potent agents. Some say that the people might need to rise up in the United States because we are increasingly having to choose between fascism and neoliberalism - all the while the oligarchs line their pockets. — ToothyMaw
And yes, I do maintain that duty is the most powerful motivator, as it can override just about any other consideration if the human is manipulated correctly. Remember the Third Wave experiment? — ToothyMaw
I do think the usual idea of the fields is that the waves aren't distinct from the field, the waves are literally perturbations of the field. I don't know if there's any conception of quantum fields where the waves are somehow distinct from the field, never heard of that idea before. — flannel jesus
I find it strange, the way you seem to get hung up on words being used in ways you disapprove of. Analogies play an important role in the way humans communicate things with each other and the use of "wave" to convey somewhat analogical things about electromagnetic fields has been going on for longer than either of us have been alive. It looks to me like you are fighting a losing battle.
What do you see as a problem, with having a notion of "wave" that needs nothing more than space to propagate through? — wonderer1
Importance and significance implies value, yes - but be careful not to assume that all value is judged by human minds, or according to a single system of logic. And no, importance and significance (value) can be meaningful simply in relation to other values. — Possibility
Why must importance and significance only be judged in relation to human minds? — Possibility
When value is recognised as a variable (as in mathematical logic), it is freed from the affected judgement of human minds (that assume they are logical), and perceived only in potential relation to other variables. — Possibility
We need to include non-human matter in discussions about agency, importance and significance. — Possibility
This requires a new logical framework, most noticeably in the area of grammatical logic. But this is not a matter of quantum mechanics dictating changes to grammatical logic, but rather bringing discursive practices into the intra-active process, acknowledging their significance as inseparable from the material practices of ‘doing science’. Because I think grammatical logic, properly understood and configured, is actually the key to our sustainable future. — Possibility
Consider that a hurricane consists of both actual and potential matter, as well as actual and potential form. — Possibility
If you have to keep referring to a ‘living human mind’ or a ‘divine being’ to make the system work, then you have a self-shaped gap in your understanding. Humans are not necessary beings. — Possibility
You keep trying to explain events in terms of objects, but it’s not the same structure. ‘Active’ and ‘actual’ have different qualitative structures for an event and for an object. Try to explain “acceleration” without reference to an object. Try to describe an entire acceleration event. You cannot use your current understanding of grammatical logic to describe the event - you are forced to change your perspective. But do you even notice that you’ve changed perspective? Do you recognise that you are describing an instantiated observation of the event, when I’ve asked for a description of the actual event? How can you describe ‘acceleration’ by simply describing an object at the point it begins to move? How is this describing actual acceleration? — Possibility
No, fields have been previously assumed to be the property of something, but evidence from quantum experiments has brought this assumption into question. Your first clue should have been your appeal of ‘always known to be’. You have to remember that we’re talking about relational structures of significant variables as active (not actual) entities in a four-dimensional system. — Possibility
Values don’t exist in a single hierarchy, anymore than all events exist on a linear timeline. — Possibility
How can you be so certain you ‘know the truth’ of reality, if you cannot use it? Philosophy is the love of wisdom - wisdom being knowledge of correct action, not simply knowledge. — Possibility
And yet you automatically exclude what doesn’t adhere to the doctrine of grammatical logic, despite being consistent across the logical structures of both mathematics and science. That sounds like blindly following doctrine to me. — Possibility
On your view, why does it matter what material the conductor is composed of, or what the cross sectional area of the conductor is? — wonderer1
Matter (noun): 1. physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy.
2. a subject or situation under consideration.
(verb): 1. be important or significant.
I would say that ‘matter’ is not so much a concept as the human conceptualisation of an idea. In reference to things, matter is physical substance, but also mental substance. But in reference to activity, to matter is to be important or significant. You can’t just ignore these additional aspects of the conceptualisation of ‘matter’. And you can’t declare them ‘different substances’ without an understanding of how they relate. — Possibility
First of all, I didn’t say that ‘immaterial’ implies inactive. I said it implies that the activity in question doesn’t matter. What you’re arguing is that the only way this kind of activity can matter is if it actually matters to living human minds FIRST. Quantum mechanics refutes this, and so does neuroscience. — Possibility
The first assumption is that ‘categories’, with their determinate boundaries and properties, divide up reality with mutually exclusive accuracy. So, according to Aristotle, a particular event cannot be both potential and actual. — Possibility
But that necessary event need not have become fully actual prior to all other events in the series. It only needs to have begun. In which case said necessary event - the universe itself - is being, and even now, still in the process of becoming. So there is no reason for the universe in its becoming to be denied agency, except that this affects us in a way that impacts our homeostasis. — Possibility
True and mathematical Newtonian time exists; it is a real entity; it is the gravitational field — Carlo Rovelli
For his part, Aristotle is right to say that ‘when’ and ‘where’ are always located in relation to something. But this something can also be just the field, the spatio-temporal entity of Einstein, because this is a dynamic and concrete entity, like all those in reference to which, as Aristotle rightly observed, we are capable of locating ourselves. — Carlo Rovelli
Understanding is not about grounding concepts in just one ‘logical’ system — Possibility
‘Good dialectics seeking truth’ is just seeking to ‘support the usefulness of their own discipline’. Surely you see this? — Possibility
Compatibility does not require a ‘higher purpose’, only a broader understanding of each discipline. — Possibility
To declare otherwise is to put your faith in a narrow ideology, to blindly follow doctrine. I honestly thought you were more intelligent than than, and I’m a little disappointed at all this pontificating. What is truth if it isn’t — Possibility
As to cause, one of the basic presuppositions of Newtonian science, Newton held that some things were caused and some things were due to the operation of law — tim wood
But you it seems would take a bit of snake, and of newt and frog and bat and dog, and some other ingredients, and boil up a potion that you would call knowledge, but in fact is nonsense or worse. So, for any of your "conclusions" in your posts, never mind all your qualifications and variant perspectives, how do you know? — tim wood
I'm afraid your source is not very good. It seems to be mistaking the skin effect which is applicable to AC signals, for a general rule about electrical conduction.
In either the AC or DC case, electrical current travels through the conductor. That link provides some explanation as to why in the AC case the conduction of current becomes more and more confined to the outermost portions of the conductor as the frequency of the AC signal increases. — wonderer1
It seems to on any macro-scale. The "seems to" not just a throwaway phrase, but rather a pretty good clue as to what is, er, seems to be, the case. The real trick here is to not use the "I don't knows" as grounds for knowing. — tim wood
And you know this how? — tim wood
My private opinion is that the electron is particle-like, and only cloudlike in the sense that it moves around really, really fast. And it would not offend my scientific sensibilities if someone were to suggest that maybe the particle-like in its motion sets up a kind of standing shock wave, though in what medium or made of what I don't know. — tim wood
However, electrical energy does not travel though the wire as sound travels through air but instead always travels in the space outside of the wires. This is because electric energy is composed of electric and magnetic fields which are created by the moving electrons, but which exist in the space surrounding the wires. — http://scienceline.ucsb.edu/getkey.php?key=3199
"Validated"? I'm not sure this will be a useful discussion. It seems you want to commit the fallacy of, "Because I do not know, I know."
And if you were honest about it, you'd have taken note of the quoted remark above that make clear that the term - and the concepts - of spin are problematic, — tim wood
Then, Bohr, Planck, Heisenberg, Schrodinger and friends introduced QM to the world. They said that there are some properties of particles that, prior to measurement, we can't actually tell a Classical story about. If we shoot a particle at t=0, through a double slit for example, and measure where that particle landed at t=100, we might be tempted to ask the question "ok, so where was that particle at t=50?" If the world worked classically, then there would be an objectively true answer to that question - even if we as human beings couldn't find an answer. If we can't find an answer, that's just our own ignorance, but there still *is* an answer. QM said, actually, there *is not* an answer. Or at least, not a *singular, definite answer* -- that's the phrasing I like to use. Prior to measurement, some of these properties of things like Photons and Electrons do not in fact have singular definite answers - not even to God. If God himself were to peer into the universe and look at that particle at t=50, he wouldn't have a singular definite answer to the question "where was that particle?" (Please note that I'm using God as a narrative tool, I'm not a theist. "God" is just a stand in for the idea of some external entity who could, in principle, know the world as it really is - could answer any question about any system without disturbing that system). — flannel jesus
The detectors reliably and consistently measure something, called in this case spin - and it is at the moment irrelevant as to what spin is - and this spin deemed to be an aspect or quality of the particle itself. — tim wood
Denial of the particle having this spin except when it is measured begs the question as to how the particle knows it's being measured and reacts, and what, exactly, triggers that knowledge and reaction, not to speak of the time that all takes. — tim wood
It seems you fail to distinguish between spin and "spin." Forget the ordinary English word "spin". And for clarity's sake just for you in this post let's call the other spxn. Let's suppose what is actually the case, that certain people use the term that we call here spxn to represent a set of ideas that they have collectively, and that they can convey to each other by speaking and writing the word spxn. In as much as I am not one of those people, I will leave to them the choice of their own words for their own use; and I (shall) assume the the word is efficacious when used by them among themselves. So much for the word — tim wood
The three-dimensional angular momentum for a point particle is classically represented as a pseudovector r × p, the cross product of the particle's position vector r (relative to some origin) and its momentum vector; the latter is p = mv in Newtonian mechanics. Unlike linear momentum, angular momentum depends on where this origin is chosen, since the particle's position is measured from it. — Wikipedia: Angular momentum
I thought you were opposed to such antics. — NOS4A2
Maybe I'm misreading you, MU. It seems to me you're objecting to the use of the English word "spin" to refer to something meaningful to a technical user as a term of art. If that's the case, why? — tim wood
We've seen a lot about proving things to you. No one can prove anything to you, which you do not want proven. But anything which you want proven, you readily prove it to yourself...proving to me.. — NOS4A2
"When certain elementary particles move through a magnetic field, they are deflected in a manner that suggests they have the properties of little magnets. In the classical world, a charged, spinning object has magnetic properties that are very much like those exhibited by these elementary particles. Physicists love analogies, so they described the elementary particles too in terms of their 'spin.'
"Unfortunately, the analogy breaks down, and we have come to realize that it is misleading to conjure up an image of the electron as a small spinning object. Instead we have learned simply to accept the observed fact that the electron is deflected by magnetic fields. If one insists on the image of a spinning object, then real paradoxes arise; unlike a tossed softball, for instance, the spin of an electron never changes, and it has only two possible orientations. In addition, the very notion that electrons and protons are solid 'objects' that can 'rotate' in space is itself difficult to sustain, given what we know about the rules of quantum mechanics. The term 'spin,' however, still remains." — tim wood
May I know what you were drinking before you wrote your post? I should like to try some for those occasions when I too would like to loosen my grip on reality. — tim wood
This is a formidable challenge. Do you think this makes Leibniz Law untenable entirely? — Count Timothy von Icarus
Or can we talk about entities' properties without any reference to an observer? If the latter, can't we do the same sort of abstraction and apply the Principle to the set of all possible discernments? — Count Timothy von Icarus
That is, within the set of all possible discernments, there is no case in which x ≠ y, thus x = y. — Count Timothy von Icarus
All possible discernments are not "subjective discernments,"... — Count Timothy von Icarus
Perhaps this trivially reduces the principle to Leibniz Law, but I don't think it does because Leibniz Law leaves open the possibility of bare haecceities of difference, differences that never make any possible phenomenological difference, which is what the Principle denies. — Count Timothy von Icarus
Different because the respective spins are not limited to opposites. — tim wood
The main difference is that you believe any understanding of reality must conform to grammatical conventions (which is a reduction of logic), whereas I believe any grammatical convention should adjust to accommodate a rational understanding of reality that may fall outside of its existing framework, — Possibility
A couple of points to clear up here. Firstly, there is a difference of configuration between not requiring ‘materiality’ and being ‘immaterial’. The former acknowledges a variability in the configuration of activity/being, while the latter offers only one configuration - enacting an agential cut that excludes activity sans three-dimensionality from mattering. — Possibility
Okay, you’re making great leaps of assumption here. Not requiring three-dimensionality is NOT the same as non-dimensional. Subatomic particles lack a fundamental three-dimensional inertia. At least one of their dimensional measurements is in a constant state of flux, but this doesn’t render them non-dimensional, only not fundamentally three-dimensional. They can be configured as relevant/significant (material) in a four-dimensional (active) system, but in a three-dimensional (inert) structure they are considered ‘immaterial’. — Possibility
The reason I use a dimensional structure is because it retains an overall sense of logic and rationality as we move between limited systems or conventions of logic: ie. grammar, mathematics, physics. — Possibility
My argument is that the findings are sound, and are compatible with a broader understanding of grammatical forms. — Possibility
What quantum mechanics demonstrates is that materiality extends beyond the activity of material things. — Possibility
Grammatical conventions need to be in the mix, but for them to effectively intra-act we need to accept their fundamental variability and limitations. It seems you’re not prepared to do this. — Possibility
This is pure sophistry. It is not just elegance that I’m after, but elegant accuracy. Dualism is clunky and ignorant at best - its most glaring ambiguity lies in the absence of a logical, qualitative and dynamic relational structure between ‘material’ and ‘ideal’ Forms. — Possibility
Grammatical conventions have logical form but are not ‘logic’ in the ideal sense. Accuracy in practise is more indicative of ‘truth’ than words systematically arranged. And the accuracy in our practise of quantum mechanics makes it very clear that the remaining ‘fault’ in temporal conventions is in our grammatical logic, not the physics or maths. — Possibility
