It's another form of an aether. If the so called field is undetectable, it might as well not be there, even if it really is. He seems to be simply pushing the problem of a photon "knowing" there are two slits back onto a medium "knowing" there are two slits. I am not sure how this in any way clears anything up... I see parallels to arguments concerning the idea of god actually, like "who created god" or "if god is undetectable, why believe he exists?".

The idea of a fixed particle may be wrong, but that would not be earth shattering to modern physicists.

First of all, when you examine any light at all it is through absorbing it, and since you are observing the wave-packet itself, you need no medium.


What is the wave packet then? You seem to be kicking the can.

It is a wave-packet, not a physical wave. Physical waves need a medium because they are the result of a disturbance of that medium. Unless you also want to make up another type of useless aether, the idea of a medium is not necessary.


And your wave packet is nothing but a variable for word usage and implies only a hunch notion of behavior but it doesn't account for all the observed phenomena of electrons. There are problems that need to be addressed and that is all I've been doing since I mentioned it.

But also the idea of a bubble is not necessary, the goal is not to state the "real" way things are but to find an accurate concept, accurate in its ability to explain phenomenons observed, but its use is not to tell you what is observed.


I am aware but altered frame of reference can shed insight into observed behavior and this is why it is used. A mental tool to help guide the math down a different line of thinking. It is asking the question, what if they were like this, what would be the observed behavior be? The math will point it out. The bubble theory does account for observed behavior.

So if the concept of a wave serves best, then there is no need to replace it with a "bubble", and so far I have yet to see how your bubble analogy could come to terms with wave functions better than the idea of a wave.


[/COLOR]Best for you maybe? The current understanding is not a complete model and it has problems that simple calling it a wave, does not answer.

Hows does an image of this cat get into your brain (and then into "consciousness")? Your eyes, of course, but these light waves hit your retina, which translates them into another kind of information which the brain puts back together.

What does the fact that your brain cannot directly sense the cat have to do with whether you can or cannot directly sense the cat?

A wave packet is a wave with finite boundaries. This is possible through the interference of multiple wave functions in series. So the idea of interference is more than just conjecture, it is a result of the math of adding and subtracting wave function series.

It is a term that helps describe what the math shows, and as such is useful.

Tell me, how exactly does one do bubble math? I find nothing wrong with new ideas, but they need to be applicable, and from what I've read I haven't found anything that adds to quantum concepts, but I may just need you to elaborate on specific points where you feel it does.

There are other things to be considered. If undiscovered particles or force-carriers, whatever you want to call them, complete the model, or an understanding of other dimensions complete the model, then the idea of a wave could be spot on.

I know what wave packets are. You can't seriously think this is the question I was asking.

Too much to explain. I don't think you take me seriously anyways since you can't seem to understand a particular question I asked.

Yeah, and that still does not say what the wave is, or consists of. I am not in conflict with waves. I am not rejecting waves, and your focus seems to be that I am. I never was, I am still asking, what is a wave, but you seem to not understand the question.

You see I thought we were past that already, because the purpose of the wave concept is to describe a set of phenomena, not to tell one what the phenomena actually is... so if you are asking me what is a wave, I can describe it to you in mathematical terms or through physical examples, but as far as what is a wave, I have no idea. If I ask you what is a bubble are we not in the same conundrum?

Not necessarily because the thought and implications is the leading purpose. That is all I was stating it for. I can do some assuming here to show you what I mean. When I said bubble, did you envision something that completely surrounds the nucleus of the atom? Like a ball with another ball inside it? If this was your impression, it is not what I was referring to. In fact it would be more like a doughnut instead. On top of that the bubble is not static in shape but instead it is isolating and twisting. It's position is in all points around the atom and has no fixed position. It doesn't even need to orbit or spin but it can if enough energy causes it to spin or move. So this electron doesn't even use energy at all like orbital theories neglect. If the electron is excited it can expand or contract depending on how many other electrons are present. The electron can even bump into itself from time to time causing it's motion to switch accordingly, which is something that particle wave theory has never accounted for. One of the hardest things is determining position however the easiest is energy. This bubble theory actually is supported by the difficulty in determining position and at the same time embraces the energy result the same way. There is no conflict at all. I could continue and go into the math but it's only going to end up an even longer explanation stating the same things I just have and only a few people here would even consider reading it.

What is the difference between your doughnut bubble and the idea of a valence shell?

Also, the idea of harmonics in waves is a good explanation for quantized electron orbits, because it limits the possible energies of the electron to ones that are harmonics of the first.

The uncertainty principle makes common sense, minus the h-bar/2. The faster you take a picture of something, the less blur you see on the film, but the surer you are of the position of that something and vice versa.

They are similar but for the most part the bubble deals only with the electron itself and not it's actual energy. Since you brought it up, I'll say one other problem is dealing with the valence shells with a particle theory. If you can envision the bubble not actually expanding but instead inverting itself in the Y direction, turning itself inside out, you can actually account for a change in position without a loss in energy to do so. You get a higher valence level without energy loss.

Not in conflict with an oscillating electron, it would actually carry the frequency until it either bumped or obtained or loss energy.

I'm not sure exactly how you want me to relate to the whole taking a picture because if light does not travel instantly then every photon will arrive at different times and in different amounts which would blur the picture. The faster you take the shot the fewer photons you allow in, making it less likely to blur.

I'm not sure I get what you mean, but can this account for more than two valence shells?

I don't know what you mean here...

Think of just the picture, not the process of taking it. If you see a picture of a car without blur it looks stationary (e.g. in one place), but if you see a picture of a car with a blur, it looks like it is moving (e.g. momentum).

But I think it is earth-shattering to philosophical materialism, actually. With all due respect to all of you who have done the math - and note, I am very careful not to claim any knowledge about this matter which relies on having done that - I still say, that at this point in this thread, even taking into account all Krumple's arguments, which may be perfectly valid, for all I know, the question of whether an electron exists is still an open one.

We have already touched on the possibility discussed by many physicists that electrons pass in and out of existence. Is it too big a stretch to say that electrons really only have a tendency to exist? It certainly seems true of what physicists call 'virtual particles' which are now an important part of the standard model.

One thing I think everyone looses sight of in all of this is the distance we have traversed from the original premise of Enlightenment materialism, namely, that the ontological basis of the universe is the atom. The atom, so conceived, really ceased to exist the moment it was shown to be composite. The whole idea of the atom is that it is ontologically primitive, eternal, and non-compounded. (I am speaking philosophy here, not physics.) Now we have a world picture, really unintelligible to anyone who does not have postgraduate degrees in mathematics, where 'nothing' contains immense amounts of energy, the fundamental unit of matter is called a 'particle zoo' (with at least SOME empty cages still in it) and matter and energy are convertable.

So as for philosophical materialism, so called, to quote the memorable line uttered by Private Hicks in Aliens, it's 'game over man', as far as I am concerned. We still cling to the hope that at least the fundamental nature of reality might be described by science and or mathematics, but many have long since abandoned any pretense of knowing what it is.

I believe fast means that organs are not the things experiencing. We are the things that experience with the organs (for instance, eyes).

We must make the distinction between the mind and the brain. Neurologists make the mistake of not doing this all the time, from what I hear. Someone made a thread about this not too long ago and called it the neurological fallacy - to mistake the mind for the brain.

Well certainly not, but I do consider the brain to be the essential part! If everything else was stripped away from a person and all that was left was their functioning brain would you not still have a person?

So in this sense I see the brain as directly connected to the idea of "I". So to separate the two in any meaningful way seems odd to me. Not that I don't feel we are more complete with a body mind you.

Sorry, I edited my post right as you responded. Again, we must make the distinction between the mind and the brain. Your brain is not experiencing anything. You are. Fast is correct.

But our brain is not our consciousness. That is why it is considered a phenomena - there somehow is an "I", a consciousness experiencing the world, independent, but involving, our sensory organs. Our functioning brain assists us in experiencing the world, much like a functioning ear or nose can, but any one particular organ is not what we would call consciousness. It is not what we call a person. And these organs are not the things which experience. Would you say that you are happy, or that your brain was happy?

But is there not a problem if all of that sensory input could be artificially injected into the brain when no body is present? Does that not push the meaningful part of consciousness back to the brain?

"Would you say that you are happy, or that your brain was happy?"- what does it matter what I say? If my concept of I exists solely in my brain then my brain is happy.

Think of it this way, if a computer became conscious, would it need sensory input? Or would it only need a prefabricated brain-like structure.

What I mean to ask by this is if consciousness is directly associated with sensory input... because that seems to make the idea of "I" actually dependent on things outside of the body.

@fast,
If a computer became conscious, eh? Sounds easy, but it isn't. This is the general area of Artificial Intelligence, which sounded quite plausible in 1980 and now looks remote. Why? Because computers lack common sense. Common sense might sound common but computers ain't got it.

Quote:
A dog knows, through whatever passes for its own sort of common sense, that it cannot leap over a house in order to reach its master. It presumably knows this as the directly given meaning of houses and leaps - a meaning it experiences all the way down into its muscles and bones. As for you and me, we know, perhaps without ever having thought about it, that a person cannot be in two places at once. We know (to extract a few examples from the literature of cognitive science) that there is no football stadium on the train to Seattle, that giraffes do not wear hats and underwear, and that a book can aid us in propping up a slide projector when the image is too low, whereas a sirloin steak probably isn't appropriate.
Steve Talbott, Nature, Logic and DNA, Antimatters Journal, Nov 2009

The brain is not a computer, and the mind is greater than the brain (there are many on this forum and others who will challenge both these statements). From what we know, the brain only ever operates in the context of a living body, and a living body only ever operates in an environment. All of these are inter-dependent and mutually define and re-inforce each other. It is a huge fascinating study in areas such as cognition, systems theory and even deep environmentalism.

now - do electrons exist?
