A capacitive parametric resonance. -------------------------------------- The electron, proton and space between them is the condenser. Thus at each complete turnover of an electron, the exterior electric field of a wave renders parametric change of a capacitor CAPACITANCE of Atom. Please show your calculation for the capacitance for an isolated atom. Please then show how you derive your equation for the dependence of the capacitance on the strength of the electric field. It can be made by a rather refined method in zero approach. You evaluate capacity of a spatial figure of the relevant geometry of allocation of a density of charge of electron cloud of a concrete electron concerning a core. Evaluation of differential capacity in first and other orders I abandon on your discretion. ;-) Now Aleksandr, I answered your questions on RC oscillators. You are the skilled and interesting interlocutor. Thanks for the help. This is your analogy so it is up to you to present it. The conceptual systems of physical ideas are a main core of physical sciences. I shall issue to you other analogy from a gravitation. Craig Markwardt wrote in Message: http://www.google.com/groups?selm=on...ysics.wisc.edu " 3. Certain well known orbital configurations.

The conceptual systems of physical ideas are a main core of physical sciences. The mathematical statement of conceptual system of physical ideas is rather relevant, but minor aspect of physical science. The mathematical statement of conceptual system of physical ideas is run-down of these ideas on the other language. The horse should be at the front carts, but we have major problems, if the horse jolts a cart behind. The schizophrenia is inadequate reflection of a reality. From an intermixture of true and error ideas it is possible to receive any effect and result. This history has a place in GR. ;-) 2. Inductive parametric resonance. -------------------------------------- In system an electron and core, the motion of an electron is the loop of an electric current. Thus, the electron, moving on a closed path, can be submitted as INDUCTANCE. Thus at each complete turnover of an electron, the exterior magnetic field of a wave renders parametric change of INDUCTANCE of Atom. Please show your calculation for the inductance for an isolated atom. Please then show how you derive your equation for the dependence of the inductance on the strength of the magnetic field. It can be made by a rather refined method in zero approach. You evaluate inductance of a spatial figure of the relevant geometry of allocation of a current density for electron cloud of a concrete electron concerning a core. Evaluation differential inductance in first and other orders I abandon on your discretion. ;-) Again, this is your idea, you can't expect others to create it for you. It is my innermost desire. Do not discourage me... ;-) 3. Complex parametric resonance of Atom. -------------------------------------- The integrated Inductive parametric resonance and Capacitive parametric resonance is the mechanism of a complex parametric resonance of Atom. Inductive component of a complex parametric resonance and Capacitive component of a complex parametric resonance can be in "phase", in "antiphase" or disbalanced state. Please demonstrate how this is derived from your results for points 1. and 2. At first we should complete arguing 1. and 2., and then we can advance further. :-( Agreed, but to do that you will need to present something that can be argued. It is my innermost desire. Do not discourage me... ;-) |

However, the reason I juxtaposed your quotes is that in the first you say: "my argument is that waves 'in a medium' ,contained if neccesary, exhibit resonance." and "Of course I realize that waves on there own arent resonance." yet you had previously said: "This ... shows how classical waves can resonate in an open system and create maxima (in this case bands rather than nodes)" "in a open infinite universe the aethger medium could resonate and nodes of maxima would be possible." "above I have shown that the medium does not need to be contained to resonate and create maxima." "do you agree that a medium can resonate in an open system. as I have shown above?" Clearly you had been arguing that waves on their own could exhibit resonance, and as far as I can see you are still doing so. As I have said before, the problem is not your grasp of the physics, just your understanding of the terminology. Adopting the same meaning for the word as everyone else will simply help you communicate. George |

Especially considering I juxtaposed that with the second part of the line that says that I think that waves in a medium can exhibit resonace. Initially I thought that if I could get David to agree that a contained system could resonate with a medium etc however you want to word it then I could then put forth an argument that shows how then a node in a contained resonating system could in a sense be comparable to a wave only atom mechanically speaking. You present an argument that says that the medium has to be contained to exhibit resonance whereas yes iniitially I was hoping to argue that an infinite homogenous universe could aLSO do the same . OK I wont push that open homogenous idea right as you in a sense provided an answer in that your post a few back said that a sun could exhibit resonance and even interstellar space with gas clouds could also be interpereted as `contained ` systems`. Thats your quote not mine and I `ll take that as the implication that an infinite universe is NOT homogenous and therefore is not uncontained at any one point. Hence my infinite universe can at any point have a `contained` prerequisite` But initially though YES I assumed that Craig was trying to suggest that I didnt know the grammatical or dictionary difference between the two words. Otherwise if he had said a medium can exhibit resonance I would have said yes and argued it using the above argument. So what do you think ?You suggest ear;ier all interstellar space is not homogenous and you admit a medium contained can exhibit resonance like the sun.Whats wrong with me then saying OK At any point in the universe be it in a star or solid or interstellar gas resonace can be exhibited and therefore that could be said to be how a wave only atomis explained.And thats why more complex atoms can only be created in denser mediums like stars. And how did the initial hydrogen building blocks get created . I cant explain that but neither can QT as it cannot explain before less than a fraction of a second the big bang as conditions are not understood. Som if QT cant explain parts then wave theory gets that same `out`so to speak. Sean |
