If so, what physical parameters define them?
I think that the observer this information concept but not physical.Loren Booda said:If so, what physical parameters define them?
Yes, that's basically my view too. If an entity suspected of being non-physical were to interact with a physical entity in the same way that another physical entity does, what is it that makes it non-physical? So if there is a non-physical reality out there, it seems logical we would never be aware of it in the way we are aware of consciousness or information, and so have no reason to think it exists (whether it does or not).sameandnot said:you are essentially assuming that "what is", the Reality, is fundamentally physical. i say this, because you must be referring to the "problem" of QM, where the act of observing affects the outcome of "physical" events. therefore, i say, you are in assumption that the universe is basically "physical", and that an observer must, in fact, be "physical". for if the observer is non-physical, then Reality, too, it follows, is non-physical. see?
Loren Booda said:If measurement involves physical interaction with the observer, as QM seems to indicate, why has the magnitude of that action upon the observer never itself been measured?
alfredblase said:So yes from my point of view, (the only one that exists, or at any rate the only one that counts) an observer has to be physical (try proving me wrong). There may be a non-physical observer out there somewhere but it doesn't exist as far as I'm concerned, and never will unless I go completely insane or as the case may be, unless I recover my sanity.
mmarko said:Forgive what may seem like sophism.
If an observer exists it exists in the universe. The universe is physical.
It is the definition of physicality. Therfore an observer is physical.
As Wittgenstein discusses, only the physical can be discussed. The meta-physical cannot. Therefore a discussion of existence outside the logical space of existence is not something that can be defined in order to be considered.
If an obsserver were not physical, the observer would be irrelevent. There is no definition I know of to descibe the existence of a thing outside the system in which all existence takes place.
There is no meta-position possible to make an extra-system description of the universe, therefore it is impossible to describe this system in terms of anything else. An observer which was not physical in this system would probably be defined as physical one or more meta positions (using a meta-language) upward. So within a wider hierarchy of references our "non-physical" observer would still be physical even if we called it not physical.

Loren.Loren Booda said:El Hombre Invisible,
"Upon measuring directly a displacement of Planck length L*, the measurer would receive a momentum reaction equal to h/L*, or 4,000,000 gm-cm/sec, beyond the kick of a mule" (from my website). Any QM action, by and upon the observer but greater than h, seems disallowed under quantum gravity, while classical actions may exceed (and in fact may also be defined by a lower bound of) Planck's constant.
But this is the thing: if the act of measuring has no impact on the observer, the observer wouldn't have actually measured anything. Assuming the observer measures the object by sight, and since we're measuring something on the Planck scale, this must be with the use of some device, what we are really observing is photons from this device with our own natural optical and nervous systems. This does have a measurable effect on the observer.Loren Booda said:El Hombre Invisible,
By the the purported reaction of Planck momentum on the observer from measuring the Planck length object complement. This reaction to the observer is usually unnoticable. For a gamma ray of highest frequency (1030 s-1), one might have a reaction of 10-8 g-cm/s, still relatively small.
I disagree this fits here. I suggest you start your own thread?Rade said:I posted this elsewhere with little response, but it also seems to fit here. My question is, suppose it were possible to invent a quantum machine and that this machine was able to conduct "internal" observation. Would such a machine be physical and would such a machine be able to violate the HUP, that is, observe two events with 0.0 % error at the same time ? All talk about the HUP assumes an external observer--but what of the internal observer, observing itself ? I have no answers, just questions.

Well ...Being that I am on the other side of the coin. I.E. the other alternative (conceptual reality rather than physical). Why is it that Physical reality must follow certain rules, while conceptual reality does not? Why is it that the concept me somehow has the ability to walk through a concept wall, while the physical me can't walk through a physical wall? Why can't Conceptual reality have the same rules as your choice (physical realty)?Anyone who really believes they're not physical wouldn't eat and would definitely try to walk through speeding trains and across the atlantic. Any no voters doin' much of that these days?

quantumcarl said:Conceptual reality is governed by a rule that is deeply rooted in physical reality. In order to conceptualize any reality whatsoever you apparently need a physical brain. Try having your brain removed and get back to us on whether or not you are still experiencing a concept of reality/no reality etc... (conceptually speaking)
Castlegate said:the universe as a whole is not a physical entity.
I love a skeptic.quantumcarl said:Is this something one discovers after a brainectomy!?
Is this a concept cooked up by the (very physical) brain in your head?
What brain has actually experienced the "whole universe" in order to be able to support your statement?
Castlegate said:I love a skeptic.
Think that your brain is not made up of bits of matter separated by nothing at all, but rather forms of nothing at all that act in accordance with conceptual laws. Your overall experience is the same, but your approach to it is completely different.
And that energy is no more than geometric entities composed of nothing at all. They move in accordance to conceptual laws. Sounds like a plan.quantumcarl said:I disagree.
Concepts are what our brain uses to describe the sensory data it receives.
Conceptualization creates an illusion for people who can't handle the reality of the universe in its raw form... which is pure, unadulterated energy and (perhaps) the lack thereof.

Since it is obvious that you are so sure of yourself. It is beyond dificult to get you to entertain any other possibilities. In that vain my message to you is a purely physical one.quantumcarl said:"Are Observer's Physical?"
Observation requires a distinction between what is observed and the observer. The distinction is a separation and separation denotes a relative, physical quality (by definition... ie. "space between").
When there is observation there is separation and if there is separation between what is being observed and the observer then both are physical... by definition.
Further to that, the act of observing is a physical act. It does not take place without neurotransmitters, synapses, dendritic connections and axions, sodium/potassium pumps, osmosis and a slew of other physical functions, actions and attributes.
Once again, the question provides its own answer.![]()
depends, right?castlegate said:I'm curious as to what physical characteristics (thought) has.
sameandnot said:depends, right?
increase/decrease seratonin, alter testosterone/estrogen, altered state of physicality as well as mentality (they are not as different as one tends to think.).
thoughts i have also affect other people. which is to say that thoughts are not only characteristic of physcial conditions, and viceversa, but also that they are not private (strictly speaking). my thoughts about "you" do affect the totality of the "play of physicality", or the "dance of the physical".
is there a difference between 1-, 2-, 3-dimensional characterstics and 4-dimensional characteristics? in other words, to see something, statically, in a 3-dimenmsional state, surely offers the "observer" and particular kind of "physical" characteristics; can we measure affections in 4-dimensions and thereby denote physical charactersitics to something that was hitherto conceived as "non-physical"?
science, it seems, for the most part, has looked at the world, almost strictly, from the 3-dimensional perspective. that is, they "saw" things, (were able to account for things consisting of particular masses and volumes and what-not) and then attributed the affects of time on them.
can science be done from a perspective that is wholly integrated into the 4th dimension? and is not restricted to labeling reality on the basis of a 3-dimensional perspective?
i think that for all of my lack of clarity and precision, the idea is valuable. especially when we are trying to determine what is "physical" and what is "not physical"?
(mind fart: photons are not massive, but they are considered physical. what makes them different from a thought?)
Neither the "object" nor that which "observes" the object remain in the same state over time, change is the only constant. My question is whether or not the "object" can observe itself ?quantumcarl said:...However, when the object is not being observed, there's no way to verify if it is physical or not. There remains only the assumption, based on experience, that the object of the observations remains in the state in which it was observed. And it has been demonstrated over and over that making assumptions is usually a mistake.
Rade said:Neither the "object" nor that which "observes" the object remain in the same state over time, change is the only constant. My question is whether or not the "object" can observe itself ?
quantumcarl said:Observation takes place only by the use of the mechanisms and functioning stuctures of a neural network. Observation includes the utilization of the peripheral organs of that neural network, as far as is known. Nothing that takes place outside of a neural network can be termed as "observation". For instance, a video camera does not "observe"... it "records". Then the observer interviens and makes observations of what has been recorded.
In a complex neural network such as exists in the whale, humans and other animals it has been noted that some of these species are able to maintain a state of self-contemplation... or, as you put it, "observing itself".
I think the act of observation may actually be considered non-physical where the observer is required to be physical to perform that act.
Conversely, however, during the act of observation, what is being observed must exhibit all the traits of being physical (to match the observer's conditional, physical bias)... However, when the object is not being observed, there's no way to verify if it is physical or not.
