| Let say for sake of illustration that the earth is the nucleus of an atom, and the moon an electron. Quantum physics says the electron doesn't orbit around the nucleus or the moon doesn't orbit around the earth but the electron exists as wave or some kind of blur. So we can imagine the moon to be at all places of the sky at once when existed as a wave function entity. Now suppose Mars moons also existed as wave function entities and it (representing an atom with electrons for sake of illustrations) comes headed to earth to combine (granted they fulfill their charge requirement and balancing as taught in chemistry). How would the two objects look like when they are bonding (as in realistically as if you are viewing it from the surface of a nucleus). You have an earth with the moon as blur or all around earth and the moons (or satellites) of mars all around mars. When they combined. How does it happen in real time "visually" where one can imagine it. Better yet, anyone aware of a site that has java applet that shows in visual demo how it all occurs. Don't philosophize that quantum physics says when the electrons (or moons) are measured. They no longer existed as wave function entities hence the mere fact the computer screen displays it says it is "measuring" it. Let's pretend we are also a wave function entity and observing two wave function entities meeting together and bonding. How would they bond or intercourse visually (step by step or descriptively) in real time or quantum time. It's been years since I last studied chemistry. So if I made any wrong assumption. Let me know. Thanks. Consc |

How about an empirical image of a real molecular orbital: [Only registered users see links. ] It looks almost exactly as would be expected from the LCAO (Linear Combination of Atomic Orbitals) theory would have it. Prof. Dewar at the University of Texas was using this theory over 30 years ago to calculate (accurately!) the thermodynamic properties of molecules that had not even been synthesized at the time. This question assumes that there would be "something" to see. The Heisenberg Principle prevents us from being able to detail the behavior of an electron (or two) in space and time in terms of anything remotely like "visual tracking" of the electrons. We can know the quantum properties (charge, spin, energy, angular momentum, and the orbitals) associated with each. We certainly could not 'watch' as they make the transition from independent movements to a state in which they are bonded to each other, as they are quantum-mechanically identified as either bonded or not bonded. .. ..

QM provides a completre disciption of Nature. QM doesn't predict that which is not observed, nor can one observe that which is not predicted by QM. However, it is possible to illustrate the evolution in time of the electron cloud about a nucleus in response to the electric field of a proton that zips by . For large impact parameters (no excitation), the electron orbitals pass through a succession of non-orthogonal stationary ground states in the changing composite field of the nucleus and the proton. In his more emergetic days, Old Man attempted such, but gave it up as to complicated and time consuming for whimsical purposes (that which produces no income or fame). For stars and planets, the calculation is much easier. Here is a link to a computer simulation depicting the capture of Earth by a rogue star: http://www.iw.net/~jakoepke/capture03e.jpg Have fun.

Science believes in calculations. It is important to ask the why of it... "Why does God exist? Who created God"... the religious must ask. Likewise, science must too or it would become religion (only with mathematics). Of course I'm not depending religion. I hate religion as it is the cause of all wars that is based on a stupid ideology. Somehow. If physics can attempt time travel. I say kill Jesus, Muhammad, etc. if they are not mere figment of the imagination. Then the world now would be a much peaceful place. Universities and classrooms can benefit great from it. It can earn you some income in terms of CD programs sold Consc |

| "Consc" <[Only registered users see links. ]> wrote in message news:1103836955.555163.84040@z14g2000cwz.googlegro ups.com... Consc requires physics to practice that which he hates in religion. Consc wants to know what is "really" going on in Nature, but there aren't any "hidden variables", like God, in QM or in the rest of physics. Via quantitative prediction and empirical confirmation, physics is, at most, sufficient to Nature. There aren't any necessary conditions in physics. In physics, you get what you see, no more. You see what you get, no less. To find out what's "really" going on in Nature, go to church. [Old Man] |

| Old Man wrote: I just want to understand what realy happens inside a wave function and the essence of measurement. Presently physicists differ with 3 interpretations. 1. Copenhagen Interpretation 2. All-Quantum Interpretation 3. Neorealist Interpretation. Copenhagen Interpretation says quantum system and measuring device are theoretically inaccessible. The quantum system's dynamic (position, momentum) attributes have no definite values, the measuring device on the other hand is experienced by human observers "classically" and the wave function being a technical tool to express their distinct relationship. This may be your viewpoints. It doesn't solve the measurement problem but conceal it. In Von Neumann's all-quantum interpretations, both system and measuring device as proxy waves and the system's waveform must collapse during a measurement anywhere in the line thru observer consciousness mediated mechanism. While Neorealist envisions both the system and measuring device to be made of particles which interact with one another via invisible superluminal waves as believed by David Bohm, Louis de Broglie and other physicists. I'm thinking what represent reality better. Consc |

| "Consc" <[Only registered users see links. ]> wrote in message news:1103883694.797527.215210@f14g2000cwb.googlegr oups.com... The wave function is a complete description of Nature. If you know the wave function for a system of interacting particles, you know every thing about the system. There isn't any limit on the accuracy to which the wave function can be known. The wave function is completely described by a set of quantum numbers (energy, angular momentum, parity, ect.) There isn't any limit upon the accuracy to which those quantum numbers can be known or measured. The set of quantum numbers that describes a system of interacting particles forms a complete description of the system. That set of quantum numbers is subject to strict causality. They tell you precisely and completely what is "really going on". [Old Man] |

| Consc wrote: Fundamentally, this was one of the hardest things for physicists of this century to accept. It is generally currently thought, based on the anguished gnashings of folks like Bohm, von Neumann, Bell, Bohr and so on who wrestled hard with it, that there IS no fundamental or deeper explanation under quantum mechanics. It's not that the reality is hidden from us, or that there are infinitely many worlds simultaneously in action through which the observer hops, or that the reality is there in the open and simply muddied by the thick-fingered influence of our experimental observations. The current notion is that It Makes No Sense to Ask the Question. Reality is what it is. Our models are conceptual instruments on this reality that allow us to predict the behavior of that reality, sometimes with great accuracy and, more rarely, in complex detail. There is no point to wondering whether the model is an accurate representation of what's really going on. That's an unanswerable question. For an excellent exposition on this anguish, and the similar anguish that went on with statistical mechanics and thermodynamics, I suggest a book called The End of Physics, by Lindley. PD |

| Old Man wrote: I know the above. What I mean is the nature of the wave function itself. Ok. Let me address the question directly that has been bugging me for days. In Airy experiment where light hit a wall. All electrons do not strike the same phosphor molecule but hit different spots on the screen. If all electrons are really alike, why do they behave differently. Orthodox physics explains that fact that unmeasured electrons are identical in being but different in behavior by appealing to quantum randomness. Physics stops at this point. Now. I'm wondering if it is possible to act directly on the wave function that can bestow order to it. Better yet, whether one can program the wave function itself. As in programable wave function. This means the wave function may not be just a dry nothingland or static but is intelligent that can accept input. Furthermore. I think electron behavior and atomic expression can be affected thru wave function programming. In the following is experiment where what we described in the east as qi or conscious energy can affect the crystal patterns of water. [Only registered users see links. ] My theory is that the qi can directly affect the wave function of the water as if qi is one entry point that can program the wave function. Of course this is not accepted by physics. I'm asking what if it can. Ok. Rather than debating what is qi and you commenting how delusional people can be. Can you suggest an experiment where one can perform at home where one can attempt to alter the wave function of a system and seeing if there is a change in the output. You can't tell me to attempt controlling the light wave function to make the light strike at the center and reduce the airy disc size. I'm talking more in terms of affecting the electron probability clouds of atoms and their collective expression such as crystal patterns in water. This theory suggests the wave function has certain limit to how you can manipulate it as if there is just a window of parameters where you can affect it like the crystal patterns of water. You may comment I'm delusional. I'm just asking "what if". And I will rely on experiments to disprove what I'm talking about. Thru experiment I also want to find out if input to the wave function is not only possible but need certain energetic configurations (like qi or others). So pls suggest experiments rather than telling me flat that it is not possible because conventional quantum physics says so. I want to know from direct knowledge it is not possible after trying many energetic input parameters to affect or program the wave function at will. Sincerely, James |
