" For first task, we found that kinetic energy increases as potential energy decreases during downward motion of the glider but the total energy remains almost constant". Notice the experimenters state "almost constant", in the introduction and "remains constant" in the conclusion which you've quoted, It appears like they contradict themselves. So what happened here? — Metaphysician Undercover
The first task is an indication of the theory of gravity. Potential energy is calculated through the measured mass of the glider and the theoretical force of gravity which has the capacity to accelerate the glider as it falls from a height. We know that as things fall, acceleration rapidly decreases due to things like air resistance, so there is a substantial loss of energy occurring with a falling object. There is no indication that the experiment was carried out in a vacuum, or any means were employed to measure all the different losses of energy which might occur. How did the experimenters account for all this loss of energy, which actually occurs in practise? — Metaphysician Undercover
Of course, they applied a "coefficient of restitution", and this coefficient varies according to the measured parameters, height and mass. That is demonstrated in task two. There is an arbitrariness to the setting of this coefficient, and this is what allows them to make the total energy equal zero, by adjusting this coefficient. In other words, that there is a perfect balance between potential energy and kinetic energy, and this is reported as remaining constant, is simply a product of the coefficient of restitution, which is a manifestation of "the arbitrariness of the value of PE": as stated. Notice that the coefficient of restitution which was required varied according to mass and height, but in this experiment it was very significant, between .63, and .77. In other words, the theoretical potential energy, which would be directly produced from the theory of gravity, needed to be reduced by about a quarter or a third, to match the determined kinetic energy in the falling glider. That's a significant loss of energy. — Metaphysician Undercover
Do you agree that the experiment completely supports what I've been arguing? — Metaphysician Undercover
Show me this system which has 50 joules, and maintains 50 joules after energy transformations. That's 100 percent efficiency. No system has 100 percent efficiency, according to the article I linked, so I think you are just making things up, to support what you believe. — Metaphysician Undercover
We shouldn't let Bartricks claim immaterial events in our minds consume no energy. — Mark Nyquist
I can't agree to this framework you've proposed here, because we cannot designate the law of conservation as "imperfect". — Metaphysician Undercover
The law is an ideal, a statement of perfection in the conservation of energy. In reality, in practise, there is no perfect or ideal conservation of energy. Yet we keep talking about this law, of a perfect or ideal conservation, as if it is a true representation, and we are led to believe that the reason why there is no perfect conservation in our practise is because we are no able to perfect our practise apparatus. — Metaphysician Undercover
And this type of imperfection (misrepresentation) is most properly called a falsity. — Metaphysician Undercover
there is not one hundred percent conservation anywhere, and our conception of energy is simply a misunderstanding. But we delude ourselves by saying that the concept is true and only our practises are imperfect, while the rest of the universe behaves in that perfect ideal way. — Metaphysician Undercover
Please take note now, of the lesson to be learned here. It was only by determining the falsity of the principle, the ideal, eternal circular motion, that astronomers could move forward, and model the orbits as other than circular, which led to the modern understanding of the solar system. It was imperative for them to recognize the falsity of the principle, that the perfection of the ideal did not exist in the real universe, for them to be able to move toward a true understanding of these motions. — Metaphysician Undercover
Now we have a very similar situation with the concept of energy. We have a similar false principle, an ideal, eternal energy conservation. Only by recognizing that this perfect ideal is false, that energy is not actually conserved in reality, in the true motions of things, that we will be able to move forward with a true understanding of time, motion, and all the real things involved in the concept of energy. — Metaphysician Undercover
So we have a whole class of these ideals, which are actually false, which have emerged out of this false ideal of energy conservation, which are simply misunderstandings, but can be very misleading to undisciplined metaphysicians. — Metaphysician Undercover
Right, it does not make these laws wrong, it makes them false. They can still be correct, as long as we invoke some sort of dualism or something like that, to account for the incommensurability between our principles for measuring the world, and the reality of the world. — Metaphysician Undercover
I don't see how you think this is relevant to "energy". — Metaphysician Undercover
Why would I choose to give any credence to the use of the terms 'immaterial' or 'dualism,' when considering what energy is?But force is just as much immaterial as "mental event" is. So in any case, mental event or not, we still need dualism to account for energy transfer. — Metaphysician Undercover
I can't say I agree with that because i do not really believe there is such a thing (meaning a real object) as a photon. So it really makes no sense to talk about a fictional particle (photon) speeding up and slowing down. However, if there is such a thing as a photon, then I would agree, that it must always be travelling at the speed of light, by definition. — Metaphysician Undercover
we apply a formula to calculate "energy", so energy is calculated, not a property of the movement itself. — Metaphysician Undercover
In simple terms, we do not ever measure energy directly, we apply a formula to calculate "energy", so energy is calculated, not a property of the movement itself. — Metaphysician Undercover
Um... How do we know it occurs when machines do it?Who read (observed) the machine result. Haha.
If no humans are involved how on earth can you make that conclusion. — Benj96
I collapse the waveform when I observe the bank balance again. — Benj96
Ha, ha. It's very obvious that Instantaneous velocity is really an oxymoron. — Metaphysician Undercover
This is why I am a dualist. I believe materialism provides us with some of the picture. And Immaterialism fills in the rest. — Benj96
Governments are ruling classes which force society to obey their laws through force. — AntonioP
A law is comprised of words on paper. If I wrote down some random rules such as "You can't eat ice cream on Sundays" or "You must wear a red hat on public buses" and called them laws and claimed that you have to obey them because I have declared them as laws, would you take me seriously? If not, then why should the politicians who write their own dictates and call them "laws" be taken seriously? — AntonioP

and take place in different settings and with a variety of teachers, as well as different cohorts for each activity, rather than the same little flock (with their same pecking order), presided over by the same adult (with his or her same competence level and preconceptions) in all subjects. — Vera Mont
Hence reinforcing the intuition that any spirit or other supposed non-physical entity, if it is detectable, is physical.
And the converse, that a spirit that is not part of this universe does not work and is irrelevant, dropping out of consideration faster than a beetle in a box.
others might be able to harden such an argument up. — Banno
Why are you framing this physical-nonphysical dualism in physical terms of "causality", "energy", "conservation laws" etc?
What warrants your assumption that nonphysical substance shares the property of "causality" with physical substance?
And if this assumption is warranted, then what warrants assuming that they are two, different "substances"? — 180 Proof
Trust me: I assess how good people are at philosophy for a living. — Bartricks
In the US, studies show that distance learning that took place as a result of the pandemic has seriously undermined the quality of education for students involved. — T Clark
A skeptical position is always a healthy one. Parents need to have system prototypes presented to them. They have to be allowed to ask all the kinds of questions you are asking and the solutions must be demonstrated to them. If no current solution exists to the problems identified, then they must be developed, based on the cyclical feedback of all stakeholders. There is an established software development method for doing this, use of alpha testers, beta testers, demo software etc.I am skeptical that there is some sort of technological solution to improving education. It seems to me that a program generated and implemented by artificial intelligence would be more rigid and limited and less responsive to students than regular schools are. — T Clark
When I think back to the good parts of my experiences in school, it is particular teachers that come to mind. Mrs. Coepcke, my 11th grade English teacher. Mr. Polychronus, my 12th grade biology teacher. Professor Deandre, my geotechnical engineering professor. — T Clark
Another thought. I think any centralized, standardized education program will be subject to political and social pressure to conform to a particular vision of what education should be. That's already a problem with regular school systems. — T Clark
What would motivate them - the same elite that's still in possession of the power and wealth - to implement your plan? — Vera Mont
They served and still serve a political, ideological, economic social agenda that isn't about suiting education to children but molding children to the needs of the elite. — Vera Mont
However, ghosts and minds would still create physical energy when they move things in the physical world, contrary to the conservation of energy principle. — Down The Rabbit Hole
What you prefer isn't the question. In general, we have to trust that parents and families are the best people to look out for their children. I certainly believe that. Sure, there are bad parents. Human social behavior is not perfect. I still think it's our best bet. — T Clark
while I believe religion has no place in school. Good citizenship, yes - informed citizenship. — Vera Mont
One must address the lacklustre to highlight the lustre. Otherwise we are simply being biased which leaves teens vulnerable and naive. — Benj96
No. Those seed banks libraries, archives and DNA repository are being prepared for the people who will restore biodiversity and agriculture after the climate crisis has passed. These are very optimistic and ambitious projects undertaken by dedicated specialists. — Vera Mont
The exact opposite. I wrote a utopian one. That/s why I dislike the disparagement of utopian ideology. — Vera Mont
It seems to me that all official (legislated, legally enforced) censorship tends toward propaganda. Even if with the most benign intentions, — Vera Mont
And there is no way that legal standard can be nuanced enough to fair in all cases; a great deal of unjust prosecutions and persecutions get swept up in a general intention to protect the public. (And of course, we can't really depend on all governments to have the best intention.) — Vera Mont
Yet the existeence of such events is as clear as can be, indeed clearer than the occurrence of any material events. — Bartricks
The issue is whether it is compatible with the principle of the conservaton of energy. — Bartricks
Unless the evidence forces us there, believing in a spirit realm feels like giving up on science. — Down The Rabbit Hole
I prefer naturalist which covers them both. — 180 Proof
Like Sean Carroll I prefer the label physicalist rather than materialist. I'm not sure there is any real difference. — Down The Rabbit Hole
I didn't say that. I said they can't be detected simultaneously. It can be detected by science but at the detriment to other certainties, which themeselves can also be detected in isolation. — Benj96
