Taking a measurement is an 'instantaneous' snapshot of the system properties at that moment. — universeness
Your 0.15 joule drop in the first 1.5 seconds for that particular experiment is just based on your own bad and bias guesstimation. It seems much closer to 0.09 or 0.1 joules to me. — universeness
The fact that potential energy is a measure of many other energies present, not just gravitational, but electrical, chemical and nuclear as well, so depending on the instantaneous state of the system when measured, there is some error bar involved. — universeness
The KE at 1.5 sec is 0.6 joules, at the first collision this becomes 0, due to the collision and then the direction is reversed, and the KE becomes positive, after the collision and then becomes 0 again before changing direction again. — universeness
This experiment clearly demonstrates that energy is conserved in this system. — universeness
This experiment clearly demonstrates that energy is conserved in this system. — universeness
As the glider moves down the ramp, value of h becomes negative. This negative value of PE annihilates the positive value of KE that is produced due to increasing velocity. Thus the total energy remains zero. — universeness
Between t= 1.6 and t= 3.9 seconds. The curved broken line has a min at approx 0.52 joules and a max of approx 0.58 joules. A difference of 0.06 joules. Quite a difference from your 15% claim. — universeness
Firstly even given quite astute and accurate explanations, he does not reconsider his position. Secondly drawing attention to his comments leads some folk into considering his arguments seriously, which is corrosive. This became clear in discussions of limits and instantaneous velocity, where clear arguments refuting his position had him doubling down, as he did here, while attracting more support than was healthy - mostly from those who, while not agreeing with him, wanted to support his right to be wrong. — Banno
I like to take ponderous metaphors like this, and bring them home: here I am, cat on sofa, clouds and trees and houses outside. Now, what IS the Good? It is here, in the actuality of the lived event that this question has its authenticity, I hold. To your point: If the good makes the intelligible, intelligible, then the good is logic and language, something Kantian? Plato is called a rational realist, and so I always thought along these lines. But the affectivity, this is happiness, joy, love, bliss, ecstasy, rapture, and other words that mean essentially the same thing. How does this "Good" effect knowledge, I want to ask. Not that it doesn't, but to characterize somehow is a worthy question. — Constance
I agree with this, but there one has to get by the difficulties. One is this: Consider states of affairs as a temporal dynamic, and not as a spatial one. — Constance
Thus, what it means to have an encounter in the world at all has a temporal model to work out, for when we talk about general principles' failure to grasp the palpable realities before us, the "before us" is a "presence" in time, in which the past and the future are a unity where recollection (history) offers the basic existence conditions out of which a future is constructed, and this occurs as a spontaneous production of our Being There. In this, the present vanishes. All that lies before me is bound to this past-future dynamic. — Constance
I say, true, yet put a spear in my kidney and the is not an historical event. Or listen to music, fall in love,, and all of the affective spontaneities that are always already there as well, and THIS declares the present., the Real with a capital 'R'. I defend a kind of value-ontology: the determination as to what is Real lies in the felt sense, and this sense of not epistemic; rather, the "raw feels" of the world are aesthetic. The "features of the particular circumstances" you speak of have their ineffability in the desire, the interest, the satisfaction, the gratification, and so on, that saturate experience. — Constance
How can you be so obtuse, MU, confusing the "lack of 100% efficiency" in thermodynamic processes with occult "energy loss"? — 180 Proof
TAre you basing this on something like 0.9 (the initial total energy shown on the graph at t=0) minus 0.75 (your guestimate of the total energy read from graph 3 at t = 1.5 sec) to arrive at your 0.15 joules drop? If that's your basis for the 0.15 joules drop, then it is probably quite inaccurate. — universeness
The shapes created by each of the 5 graph sections are pretty close to identical. They just reduce in height each time, due to the collisions. The symmetry is obvious. — universeness
he does not reconsider his position. — Banno
Of course, in his Lecture on Ethics, he was clear, talk of the nature of ethics was nonsense. Yet, the Good is at the very center of ethics. The implicit question was this, How is it that Wittgenstein was capable of, at once, a flat out denial of the possibility of talk about ethics; yet confessing this about the Good? Keep in mind that in the Tractatus ethics was transcendental. "The Good lies outside the space of facts." — Constance
You should see where this is going. Witt was struggling with the contradiction inherent in the confrontation with the world that one the one hand possessed logical delimitations, and on the other, intimated with such insistence that ethics and value were embedded in the intuitive presence of things (putting aside his own language limitation here, just to discuss) that he broke off with Russell on account of the latter failing to see that the essential point of the Tractatus was not what was revealed to be affirmed within the "state of affairs" of discourse, but rather just what it was that could not be said at all. This was the major thrust of the work. — Constance
You are also making a complete assertion. Where is your exemplar experimental evidence from an experiment that proves any energy loss cannot be attributed to energy which has changed form? — universeness
You assert that the experiments performed by physicists to demonstrate conservation of energy and confirm that conclusion in their published results are false. So, prove it, using compelling counter evidence that any tiny energy loss is NOT converted to another form, that's your burden, just like it's the burden of theists to prove their god fantasies actually have real existents (or at least 1). — universeness
You don't get to sit back in your armchair, pretending to be a warrior. Your task should be the easy one.
Reference just one experiment that shows that any energy loss CANNOT be attributed to a change of energy form. Surely any fully qualified undercover meta has access to many such proofs! — universeness
That there are things unsaid does not imply that there are things that cannot be said. — Banno
that there is always more that can be said.. — Banno
Cheers, Meta. The more that can be said, by that very fact, can be said, and hence is not ineffable. — Banno
Energy loss is energy changing form. The total energy in the universe remains unchanged. — universeness
There is no evidence of an 'outside' of the universe for any energy form to leak into or act as a new source of energy that this universe can tap into. — universeness
But just like I can't prove god/ the immaterial/ the supernatural does not exist, I cannot prove the total energy in the universe remains constant. — universeness
The burden of proof that it is a false law, remains with those, like you, who claim it is false. — universeness
You have so far, provided no compelling evidence whatsoever. — universeness
We have three: duck, rabbit and dick-rabbit. — Banno
There was more that can be said. Because it can be said, it is not ineffable. — Banno
It's not that there is something left unsaid, but that there is always more that can be said... — Banno
Your musings seem to jump around in very bizarre ways, from small gliders on small ramps to carts and now big cars travelling on big roads against 100km/h winds.
Come back when you can better control your mad jumps towards extreme exaggerations and then perhaps you will begin to understand when variables such as air resistance and friction can become negligible when they are tiny, compared to the other variables involved in the experiment. — universeness
The cardinality of the set of real numbers is aleph_1 — TonesInDeepFreeze
Yeah, neither do physicists who do physics experiments, according to you. — universeness
No, you have killed our exchange. — universeness
I think I understand physics far better than you do!
You type an insult like: — universeness
No the concerns you raise are again, exaggerated. There were no 100 km/h winds during the experiment and friction from (within the wheel??) and/or the axle will be negligible. — universeness
and then you ask me to consider another of your 'interpretations,' of what the experiment shows. :lol:
We have reached impasse! — universeness
card(reals) = aleph_1 is the continuum hypothesis. It is not provable in ZFC. It is thought to be true by some mathematicians and false by other mathematicians - an unsettled question. — TonesInDeepFreeze
This ineffable thread surely is effing along nicely — Heracloitus
…..and when we accept the natural limitations of a given system, we don’t need to lament what it can’t do. — Mww
….but can never evolve out of the kind of system it is. (Remember….dialectical consistency) — Mww
….an unjustified assertion, insofar as it is impossible to know all the things there are. The very best to be said is the mind has the capacity to know all things presented to it. — Mww
….it is absurd to suppose understanding of all things. The occasions in which some things are misunderstood verifies limits. Nothing ever being misunderstood is the only sufficient ground for the possibility of understanding all things. — Mww
On and on it goes. Give it up and go have a turkey leg or something. — Mww
No the concerns you raise are again, exaggerated. There were no 100 km/h winds during the experiment and friction from (within the wheel??) and/or the axle will be negligible. — universeness
I was advocating the truly ineffable, which manifests as a certain impossibility of the mind. — Mww
To believe in THE ineffable is to believe in things that are ineffable. If truly ineffable is only the condition of the mind for the reception of certain things, what point is there in believing in the very things the mind could never receive? — Mww
To state the existent of a thing as not impossible, is not to advocate that it is. There’s no logic in positing a possible existence when it is absolutely impossible to form a judgement with respect to it. How could we ever say a thing is possible if it has absolutely no chance of ever being an object met with our intelligence? What could be said about a thing for which we couldn’t even begin to speculate? To say such is not impossible carries more truth value than to merely say such thing may be possible. — Mww
We DO know we can never understand the unintelligible exclusively from the reality of that which IS intelligible. Pretty simple really. If intelligibility is this, anything not this is unintelligible. Besides…doesn’t “unintelligible” factually denote a non-understanding? Absurd to posit the unintelligible, then turn right around and say maybe we just don’t understand it. There may be a veritable plethora of reasons for not understanding, but the irreducible, primary reason must necessarily be because it was unintelligible to begin with.
THAT is what the ineffable is all about. Hasn’t a gawddamn thing to do with things, but only with the limitations on the system that comprehends things. — Mww
So, the PE is the same at a height of 80cm as it would be if it were at height = 0, so, mgh becomes 0 at the start and becomes negative as the glider travels down the slope. — universeness
You might find the references section of the article helpful as well, especially:
2. Energy Conservation on an Incline. Available from: [Online]

They completely neglect the fact that there is considerable friction within the wheel or axle bearing, no matter how well built or lubricated it may be.The force of friction does not do work upon the cart because it acts upon the wheels of the cart and actually does not serve to displace either the cart nor the wheels. The friction force only serves to help the wheels turn as the cart rolls down the hill. Friction only does work upon a skidding wheel.
Yep. What I’ve been advocating. There’s even an example of what something like that would be. Those cannot be named as existents, simply from the thesis that our manner of naming things could not possibly be applied to them. It is tacit acknowledgement that we have no warrant to claim our intelligence is the only possible kind of intelligence there is, from which follows that we cannot declare such things are impossible in themselves but only that they are absolutely impossible for our kind of intelligence. And it isn’t because we don’t know how, but that we are not even equipped for it.
What would be the point in believing in the ineffable then?
— Metaphysician Undercover
I can’t think of one. If a thing is already impossible, what’s the point in calling the same thing something else? — Mww
The underlined section in your above quote appears in the section titled 'Abstract,' not Introduction.
In the introduction, the words are "For the first task, we simply observed that during the first downward motion of the glider the total energy remained constant throughout the motion." In the Results and conclusions section the words "For task 1: we have found that total energy remains constant during the motion of the glider until the collision occurs". are used. — universeness
So, it seems to me, the COR is only relevant to the issue of the collisions being elastic or inelastic. — universeness
Yes, just as we do for every single word ever. Which leads inevitably to….under what conditions is it impossible for a word to be invented, such that the object the word would represent, remains impossible to talk about. Then and only then, does the notion of ineffability attain its logical validity. — Mww
On the other hand, if I already know what “box” means, I also understand it isn’t a universal conception, because I know it is a particular thing and the Principle of Complementarity tells me the one can never be the other. — Mww
And if I do know what the word “box” stands for, which means your signification and mine are congruent, I know what I’m expected to get. — Mww
It might be better for you to start a new thread on a physics forum, which employs the detailed results, from an actual conservation of energy experiment. You can challenge physicists, based on your interpretation of the results from the experiment. There are some straight forward examples available online, such as:
https://www.ukessays.com/essays/physics/experiment-study-conservation-energy-8335.php — universeness
Sure there’s a difference, but there’s nothing ineffable about it. The word representing a universal conception won’t refer to a particular example of it. — Mww
True enough. Herein is the limit of metaphysical reductionism. Conceptions represent thoughts….but there is no justifiable hypothesis for the origin of thoughts. If one wishes to call the origin of thought ineffable, insofar as there are no words to describe it, that’s fine, but we’ve already understood we just have no idea from whence come thoughts, so why bother with overburdening the impossibility with ineffability? — Mww
Truth be told, I don’t agree that’s what we’re doing. You say the problem is we try to do this thing we can’t do, I say we can’t even do, in any way, shape or form, what you say we’re trying to do, so the problem itself you say we have, should just disappear and along with it, the very notion of ineffability. — Mww
This is just as much fun as trying to fathom why some of us are right-handed and some are left. Why some of us like spinach and some of us gag on it. Only product there can be is fun; we ain’t gonna solve anything here, are we. — Mww
This from a gentleman who questions 1+1=2 is a surprise. — jgill
In the context of your link, the term Energy Loss refers to the energy that "is converted to a different form". — EricH
I am not making any claim about the truth or falsehood of the Law of Conservation here. I am simply pointing out that your example does not lead to your conclusion. — EricH
No measurement of a quantity is ever 100% correct. distance, time, density, none are 100% correct.
Is the distance actually 1cm or 0.999999999999999999999999912.......... cm.
You are over burdening the word LAW. — universeness
No, that's why science uses error bars! It is not a falsity, it just does not claim 100% accuracy. — universeness
The principle was not false, it was just that some of the assumptions and projections were wrong. Many planets do orbit on a path which is 'almost' circular. — universeness
No, physicists are fully aware, that the language used to describe the structure and workings of the universe is not IDEAL, not perfect. — universeness
A system has an energy equivalence of 50 joules. It then goes though energy transformations, and the resultant system has an energy equivalence of 50 joules — universeness
By definition a closed system is one in which energy is conserved. — Banno
Okay, then cite some of those "experiments" (or the relevant literature) to which you're referring. — 180 Proof
I think this is the main difference between us. I choose not to try to fill in gaps in our knowledge, with unnecessary terms like god(I am not suggesting YOU have employed this term), immaterial or dualism. The 'perfect' measure of the speed of light in unattainable. So is achieving human omniscience. To me, if we ever achieve the omnis, then our existence would become as ridiculous and pointless as any conception of god.
Let's continue to debate and confirm what we know and where we can go from here. Let's resist any temptation to plug gaps or incompletions in our scientific knowledge, with useless (imo) concepts, such as immaterialism, dualism or god. The conservation of energy is not false it is just imperfect. — universeness
In his book 'The Biggest Ideas In The Universe (space, time and motion,)' Sean Carroll writes about the conservation of energy.
"Both momentum and energy are conserved in classical mechanics, but kinetic energy by itself is not, since it can be converted into (or created from) other kinds of energy."
"Noether's theorem states that every smooth, continuous symmetry transformation of a system is associated with the conservation of some quantity."
"Our universe is expanding; faraway galaxies are gradually moving away from one another as time passes. Consequently, there is a sense in which energy is not conserved in an expanding universe."
I think Sean demonstrates some of the imperfection present in the conservation laws. — universeness
Yoi claim there have been many experiments that falsify these "laws", so cite one. :chin: — 180 Proof
You do not need a standard for comparison that is universal with regard to speed and time. Everyone going at whatever velocity will have their own experience of time which differs from people going slower or faster then them. Just as there is no universal standard of size, there is none for time. An elephant is bigger than a mouse because of the environment it's in; if there was no space, but only an elephant next to a mouse, they would have the same size. As for moving in an instant, the instant represents the point that is covered which is yes zero. But these sum to a positive. This is something Aristotle never understood. Motion has a forward momentum. Air doesn't move an arrow as he thought. Motion is dynamic — Gregory
Does it not follow, if all that’s needed is sufficient context, rather than entire context, that the claim “ineffable” is invalid? — Mww
If it is the case that all thoughts are conceptions, and all conceptions are represented by the word(s) that refer to them…..how can any conception be too great to be described? The representation just is the description. How can any conception, then, be ineffable? — Mww
So that which is ineffable has no word by which it is referred. For that of which there is no word, there is no conception that is the necessary presupposition for it, for otherwise, there must be conceptions without representation, which is self-contradictory, hence, unintelligible. — Mww
Imagination is that which presents objects without there actually being one. Imagination can present any thinkable object, which makes explicit imagination can present any thing that can be conceived, can be represented by words, can never be too great to be talked about. — Mww
neffable: a useless euphemism intended to obfuscate the fact it is impossible to conceive anything too great to be talked about. — Mww
Its relevant only in that I am able to distinguish between a big force/explosion and a small one.
I can also use sensory info to be able to perceive quite a range between big and small, without having to employ actual measured, unitised, accuracy via formulae. I can therefore perceive and detect 'material' aspects of 'energy' or force using something as simplistic as my own sensory input and without application of formulae. — universeness
So, if we can't detect every Planck sized unit of energy, to confirm that the original hot/cold area has the exact same amount of energy as the area now in thermal balance, then this does not mean we have to start to employ words like immaterial or dualism. — universeness
To me, it's akin to the accuracy of pi or the speed of light in a Vaccuum. We will never get 100% accuracy, will we? That doesn't make pi or the speed of light or the conservation of energy laws, wrong in any way. — universeness
Since when has the popularity of beliefs become an accurate indicator of their truth-value? — javra
No one said it was. — Banno
First, I think you can show me the experience. If you prick your finger with a pin, you can show me the experience by pricking me with a pin. Are the experiences the same? Well, there’s no numerical identity, but there’s some level of qualitative identity. There can’t be total qualitative identity because that would be equivalent to numerical identity, and that would require that I experience the pinprick as you, which is just to be you. I don’t think it’s right to describe this as ineffability. — Jamal
Do you ascribe to QFT then? If you accept a photon as a field disturbance/excitation/vibration, you still have the result that the excitation travels at a constant speed with no initial acceleration.
This is backed up by the fact that the property of mass prevents light speed motion.
Electrons don't travel at light speed as they have some mass. — universeness
If you consider something like maxwells demon, when it opens the massless door between the two chambers based on the speed of each particle it observes, would you still insist it would be applying a formula, to make its measurements? Is it not just basing it on 'fast,' 'slow.' How about when you touch something to decide on its temperature? are you applying a formula or taking a sensor reading?
Is sensing the presence of a property of something like relative position, the application of a formula?
Ignoring a measure of actual distance for a moment, simply observing the position of an object as north, south, east, west etc, is the gathering of such information formula based? — universeness
I would suggest that base sensory information is not based on formula. I see, touch, taste, hear, smell and even think before I apply any formulae to measure scalar (magnitude) quantity or vector (magnitude and direction). Is information such as 'I see there is a car there' not just based on me comparing stored images with what I see? I would not call such 'shape/pattern recognition,' a formula application, would you? — universeness
I think we can observe a property of a motion as relatively fast or slow, enough to be able to know when to jump out of the way for example, and there is no formula-based calculation, involved, just a use of instinct and sensors. — universeness
When you see your physicists again, explain to them how energy disappears and how 0.9˙≠10.9˙≠1. They will be so grateful. — Banno
So are you claiming that this:
Since a photon is a particle of light, this means that it does not need to accelerate to light speed, as it is already travelling at the speed of light when it is created. A photon does not rest and then reach the speed of light at a certain length of time, or even instantly. A photon is always travelling at the speed of light, from the moment of creation.
From a website called Ask an Astronomer, is wrong? In electron, positron annihilation, when two photons are created, there is no acceleration to light speed. — universeness
This is the mistaken interpretation which I referred to above. The sensor registers a physical change, and through the principles employed, it is calculated that this change is equivalent to a quantity of energy represent by "a photon". The photoelectric sensor does not actually detect a photon, it just undergoes a change, an effect which we calculate as the effect of a photon's worth of force. That the sensor detects a photon is a common misinterpretation. — Metaphysician Undercover
