    Non-linear acoustics

    Here's a link that someone might enjoy. It shows some properties of non-linear acoustics.

    http://www2.erasmusmc.nl/Thoraxcente.../superharm.htm

    This is basically where the intensity of a wave source is high enough that the medium doesn't propagate the signal without generating "distortion", though the distortion generated is typically of a growing harmonic structure, I'm rather certain there are ways to even have the signal become chaotic (for example, within a resonant chamber).

    Another interesting possible correlation with this phenomenon could be similar to the decay of high energy particles in collisions - space would then ideally be a perfectly linear medium and not distort the information (though at very high energies, vacuum energies might not even be linear ... virtual particles anyone?).

    Another idea that's interesting to combine with this is the possibility of a unique time reference for an observer and the possibility of aliasing http://www.dataq.com/applicat/articles/sample-rate.html.

    As a quick example, imagine traveling space through a set of rings and taking pictures as you passed through them. If you take a picture every 1 second but it takes you 10 seconds to move from one to the next, then you have a sequence of 10 images than shows this repetition.

    Let's say instead that you moved 10 times as fast. Well in this case the pictures would show the rings being stationary, so 10 times as fast appears as stopping altogether. Going 9 times as fast would make the rings appear to have reversed direction.

    If we combine these two ideas together and assume there could exist some fundamental observer reference for time (which is implied by both relativity and quantum mechanics), then if we have some waveform becoming distorted into higher and higher harmonics. It could potentially reach a point at which the frequency appeared to drop and this could appear to be in a quick chaotic fashion as well.

    In a similar sense, let's say we kept going 3 times as fast between each picture and we could describe the results as being in 1 of 10 possible states.

    t=1, we have a velocity of 1 and position of 1

    (We'll assume the velocity immediately becomes 3 times as fast after the picture is taken to avoid Calculus and additional fractal components)

    t=2, we were at position 1 but have a velocity of 3 and reach position 4
    t=3, we move from 4, at a velocity of 3^2=9 and arrive at position 4+9=13, which appears as 13 mod 10=3
    t=4, we continue doing this and take a picture at (13+3^3=40 or position 0)
    t=5 is position 40+3^4=121, or position 1
    t=6 is position 4
    t=7 is position 3
    ...

    So we have the observations of these rings moving semi chaotically (much like uncertainty in quantum physics) as the sequence 1,4,3,0,1,4,3 though actually the pattern does repeat. ...0143014301430...

    So it has a wavelength, but an additional component that can be very difficult to predict. Notice also that in a non-linear medium, this can be a dynamic rate of change as the density of the distortion/wave is altered over time.

    Anyway, those were just a couple thoughts I figured someone might enjoy.

    Re: Non-linear acoustics

    Additionally consider that such a motion could be reflective of an exponential expanding universal volume (in which case the past moment could be the "seed" for the present - that would leave alterations to a seed "forgotten" ... an interesting possibility).

    Similarly, we could see such a phenomenon as there existing a potentially unbounded em spectrum, though observer time references "bandwidth limit" this signal to a finite segment.

    Notice also that, in the above example, the interpretation of moving back and forth and orbiting around a stationary point could be interpreted as well, and the unobserved component (the fundamental velocity) would act similar to an imaginary component.

    ... as usual, just a lot more interesting possibilities to try to untangle.

    Enjoy,
    Steve

    Wow, excellent idea!!

    Yes, I forgot the observers time!.

    So let's step back a second and relook at this - if two images do not change, then an observer experiences no time.

    So now let's say we have some sequence of these in a chaotic sequence, but some are duplicates, such as 0, 3, 3, 4, 7, 7, 2, ...

    Now if there is no additional information, except for the transition for the observation, we could pair them up (which creates space and memory! ... as well as higher order moments of motions such as acceleration and jerk etc.) as transitions like this:

    0->3
    3->3 (!!! No time - we have to move down a "dimension")
    3->4
    4->7
    7->7 (Ditto! No time)
    7->2

    So the observed sequence was 0,3,4,7,2 instead of 0,3,3,4,7,7,2 and time has slowed for the observer (time dilation in relativity, subjective observations in QM etc.). Notice also that space would not have such chaotic properties and hence - no time dilation in space (though it's probably still n-1 communication, but we don't notice it, so this sequence probably shows communication via. space ... I'm not certain).

    Now there's still more (oh the pieces are popping into place now ) - now we have qualitatively different dimensional properties. Position is not velocity, nor is velocity, acceleration nor is accleration jerk, etc.

    BUT there's a trick that's likely going on that no one notices and most mathematicians seem to even over look ... notice this:

    2x != 2y != 2z != 2*# of beans in coffee bag != 2*random number etc.
    1x != 1y != 1z != 1*# of beans in coffee bag != 1*random number etc.
    0x = 0y = 0z = 0*# of beans in coffee bag = 0*random number etc.
    -1x != -1y != -1z != -1*# of beans in coffee bag != -1*random number etc.
    -2x != -2y != -2z != -2*# of beans in coffee bag != -2*random number etc.

    Multiplication by zero is NOT provable as specifically a linear operation!!! (Seriously ... so many people overlook this because the education systems keeps teaching it - you can't scale by 0, though you can add 0) I've shown many it wrong and can basically dig apart any proof that tries to claim it is - they always have a special context for zero hidden in the fine print, but it "looks" correct so everyone assumes it must be, but there's a ton of intricate details in Calculus if we really pay attention.

    So, now imagine that there exists states of an origin for all properties, though this is perceived simply as nothing or zero or void etc. In this manner we can consciously construct a "continuity" of perceptions across multiple dimensions by placing all their origins at the same indistinguishable "void" position!

    If we then look back at our 10 position pictures, there are only 9 possible velocities that can be observed because a transition to an identical state is the origin "space" and not detected, but similarly we can then "pass through" this void and construct a transition between things with orthogonal properties, such as color and sound or position and velocity etc.

    We should be able to describe all these properties as a single linear spectrum to space as well (and yes, we're almost just beginning).

    Each ring could be a derivative of the next larger, and all intersect at a common origin point for an observer. So we could arrange these as wavelengths of 1,2,3,4,5 ... etc.

    Now if we externally have a non-linear computational element, then we can generate harmonics of these and this allows for communication across this ring to occur in a very chaotic manner - so for example a sound can transition to another area of the spectrum and become a texture or motion etc.

    Now what can it do? I don't know exactly but I think it's capable of most everything describable by science - I don't think that's everything though, but possibly the closest thing to a physical model of chaos.

    In consciousness though, there can be transitions through that origin that may be potentially creative as we can "rotate" 0 in a new direction without losing the continuity of a perceptual sequence.

    Hey, maybe the mind "goes off and does 'nothing'" during sleep? Another interesting possibility.

    I think there's a point where only self discovery can see more than science, but there are already a lot of things around that could be done with science if people really put their minds to it (then again, things could be just fine ... still lots of beautiful possibilities that seem a bit tough to resist ).

    Oh well, as always, I ramble

    Have fun,
    Steve

    Very cool ... possibly even chilled?

    I've actually built something along those lines before, but this guy did it with a very simple circuit http://www.youtube.com/watch?v=4KRXo...eature=related (then again his application is simpler ... but still I'm impressed and as usual, it's got me thinking ... hmmm )

    Man, I really need to get the right 'physical hook' to get some of my ideas 'off the ground' ... gotta figure out a MacGyver (not this way http://www.youtube.com/watch?v=N8pkrN1o6GM but something with that geeky stylishness like this way http://www.youtube.com/watch?v=lP_2YffJhmg ) of doing something really cool, but I need smaller and faster fingers.

    A rose or white wine, most definitely would be better chilled.

    Now how does this post relate to non-linear acoustics?

    Not certain about the non-linear bit, but if the wine is served in crystal glasses, with varying amounts and different types of wine, I do believe that we could design several experiments around the effects of crystal, a liquid medium and acoustics.

    Invite the lot from the forum, and with the broad spectrum talent available, we could produce a music video from the combined result, to be promoted as a fund raiser for more Science.....

    Collectively, it is entirely possible that this group could compose and produce an amazing piece of objective and subjective wonder.......
