Actually complex-four-vectors (or bi-quaternions) are not the same numbers as Hamiltons quaternions. The four components have no specific meaning. The idea is, that an 'element of spacetime' behaves in a way that is connected to the neighborhood like you would multiply those numbers. This could be interpreted in the same way as complex numbers, like a spinning pointer. But this numbers spin in volume, what is difficult to describe. They whys and hows of this model are not easy to explain, but the model is very simple. The main idea is a 'mechanism' that could be ubiquitous and appear in many different forms and sizes. The rule is, that the spacelike neighbors are twisted in the same direction and that the space is anti-symmetric. Because it treats time in a geometric way, it is quite counter-intuitive, since we usually think about time as a steady flow. But relativity tells us, that time is not, but a phenomenon, that has to be measured locally in a process of counting rhythmic events. Greetings TH

But this volume or what we usually call space is an Hi Thomas. This is some pretty dynamic thinking here. I just want to point out that the adoption of a 'volumetric' interpretation can branch away from Euclidean geometry a bit more than some may realize: When we take a solid object as the means of observing the freedoms of space (rather than the Euclidean point) we observe a six dimensional freedom of space. Even if we accept that the solid is composed of points, then when we fix the position of one of those points in space (three coordinates) then the object is still free to rotate about that fixed point. Choosing another point on the object we witness two more coordinates are necessary to fix that point in space, and then with the object rotating on this new axis we see that one more coordinate completely fixes the object. This is not just a total of six coordinates. This is a structured form: x11, x12, x13 x21, x22 x33 This structure we see repeated even within tensor theory where the antisymmetric tensor becomes important in the expression of electromagnetism. Eliminate the informational redundancy of that antisymmetric tensor and you will see this form. This form is exposed through polysign to provide emergent spacetime, as well as fundamental algebraic number systems. This is recurrent information and within information theory this suggests that there is a more compact expression of theses ideas which can then yield these things, without redundancy. Anyway, I just wanted to amplify what may be going under the radar, and encourage you on down toward the fundamental, where what we overlook is what we are after. - Tim > abstraction, too, because it is timeless.

This is, what the quaternions are good Yeah. This is a pretty construction, but I feel the standing wave claim is dubious. This is a problem I see no support for within any wave interpretation of matter. The stability of the matter is in direct contradiction to wave propagation, and so I feel that those theories should address this conflict head-on. In effect don't we need a basis for the standing wave rather than just popping it out of thin air? I understand that there is experimental support for it, but that is not a theory. That is curve fitting. I guess we're near the stress tensor within relativity theory. Within pure elastic and compressible spacetime it is not difficult to picture a droplet of compressed space that would then push outward, then having stretched itself thin, would contract again, yet why the effect would not eventually dissipate as propagation throughout the medium is the problem we face. In effect you are forced to detatch space, which is no longer a continuum concept. I guess this is near to a spin foam or some such logic that I have only thin understanding of. Even within this detatched paradigm the propagation problem remains until interaction ceases. - Tim > for, because they enable a smooth transformation of the axes and could > 'morph' space into time.

From: spudnik on 7 May 2010 14:27 you are pretending to define "complex 4-vectors," but "real" 4-vectors are part of the gross and unfinished porgramme of Minkowski, to "spatialize" time, while it is quite obvious that the "time part" is not symmetrical with the spatial coordinates, either in 4-vectors or quaternions. anyway, bi-quaternions would be 8-dimensional or octonions. and, it is all obfuscation, trying to insist that a phase-space tells you what time really is; it's very useful for seeing patterns "in" time though, as in electronics (although, NB, electronics is mostly done in "1-1" complex phase-space, instead of quaternions, as it could be, for some reason .-) maybe, all you and polysignosis need to do, is work the math of quaternions ... that'll take me wome time, as well. (I mean, what is the difference in labeling a coordinate axis with a "different sign" and a different letter, whether or not negatives are even needed?) thus quoth: Actually complex-four-vectors (or bi-quaternions) are not the same numbers as Hamiltons quaternions.

From: spudnik on 7 May 2010 14:47 how do you know, Lanczos did that, and how'd coordinates geneate fractal patterns, and why would that matter?... if you believe in the Big Bang, then it seems to have had a period, as opposed to "frequency," of 13 billion years, but none of this seems to even be able to be quantized a la "biquaternions;" so, why bother? thus quoth: Lanczos used biquaternions and a couple of others. Interesting is how they generate fractal patterns: Imagine the cosmological scale and the expanding universe. That has a 'frequency' in the range of 13 billion years. Now make the time shorter to -say- a day and we get a sphere, like the surface of the Earth. If this frequency is getting higher we get very small spheres, like atoms and much higher we get subatomic structures. Than we superimpose all of those and find it would look quite like the observed world. thus quoth: you are pretending to define "complex 4-vectors," but "real" 4-vectors are part of the gross and unfinished porgramme of Minkowski, to "spatialize" time, while it is quite obvious that the "time part" is not symmetrical with the spatial coordinates, either in 4-vectors or quaternions. anyway, bi-quaternions would be 8-dimensional or octonions. and, it is all obfuscation, trying to insist that a phase-space tells you what time really is; it's very useful for seeing patterns "in" time though, as in electronics (although, NB, electronics is mostly done in "1-1" complex phase-space, instead of quaternions, as it could be, for some reason .-) maybe, all you and polysignosis need to do, is work the math of quaternions ... that'll take me wome time, as well.

So I tried to count exponents, Pis or sin/cos/exponential functions and tried to reassemble the pieces. In a way complex numbers, arc- and exponential functions and quaternions seem to be the most important. Quaternions with complex entries are bi-quaternions (or the one type of octonions - if you like. The other have eight components as quaternions have four.) Than I have drawn, what you could possible do with those numbers and compared it with observed phenomena. As being not such a good mathematician, I have searched for developed systems of this type and found a few, that look very convincing. The rest is just a bet. Minkowski was right - and all the others, that used such a construct: Hamilton of course, Tait, Tesla (!), Maxwell, Lanczos and a few in recent days like Prof. Rowland or Jonathan Scott. (Bi-quaternions I wanted to model 'internal curvature' as curved spacetime of GR: Imagine an event, described by one quaternion. Than it would require (at least) two, that an event could have some features. So these two act antagonistic and in a general case describe a straight worldline. Because gravity curves worldlines, gravity causes radiation, too. It is more easy to see this phenomenon in the trail of a comet. According to my model the trail is generated as disturbance of the solar wind, that is not radiating. But if those 'elements of spacetime' get disturbed (by a rock flying through), they get tilted and start to radiate. ) > and, it is all obfuscation, trying to insist that > a phase-space tells you what time really is; > it's very useful for seeing patterns "in" time though, > as in electronics (although, NB, > electronics is mostly done in "1-1" complex phase-space, > instead of quaternions, as it could be, > for some reason .-) > I think about programming something, because math is something, I have not enough knowledge about and I don't know, how to cast the model into formulas. This is difficult, even if you know what you want to achieve. Now I have no good idea about how to do that. But I could recommend Peter Rowlands book "Zero to infinity", what is essentially about the same idea. > maybe, all you and polysignosis need to do, > is work the math of quaternions ... Tim is among the very few, that was not rightout hostile to my ideas, but supported me a bit. Maybe his numbers would work even better. I can't tell, but it should possible to find out. > that'll take me wome time, as well. (I mean, > what is the difference in labeling a coordinate axis > with a "different sign" and a different letter, > whether or not negatives are even needed?) > Certainly 'before' could be labeled with a minus. Since a 'now' would require imaginary connections, this minus could be shifted to the 'side' and we could label the imaginary sides with plus and minus, too. The usual Euclidean view would require 'preexisting' curves, but we know, that things evolve and do not just exist as they are. So, even a line in space would be static and we know, this would be our impression, but not a physical entity. Euclidean space is meant timeless and this is not the right picture for physics. What is the right picture than? As said, my bet would be, this bi-quaternion system would work best. Greetings TH |
