  1. Are all decays in QM or QF mediated by the weak force?
  2. Aware in the same sense that you sitting in a chair makes you and the chair 'aware' of each other. I should have used a word like 'interaction'. In Quantum Mechanics or Quantum Field theory what theoretical entities are mean't to bring about the decay of a muon?
  3. Why does it have to? You are anthropomorphizing this. In special relativity we assume that certain objects have their own respective proper time and i'm assuming this translates over to QM as well as QF. Is it arbitrary when it decays then and how long afterwards? If not, then how does it know when it should be more probable to decay versus when it should if it can't keep track of how long it has been existent? Does it not have its own sense of proper time in Quantum Field theory or Quantum Mechanics? I'd be anthropomorphizing this if I said the muon must have a top hat and a pocket watch.
  4. The muon is not in the absence of changes or in this case if we assume its monadic properties are retained across time (via a physical instrument) it would be wrong to say it doesn't undergo or is absent from any change at all. Relational change (relative velocity), that is, not a change in its monadic properties (though how we would know its monadic properties didn't change is a tricky one). I'm not entirely saying that its relational changes cause it to decay but they do influence it (relative speed to other frames of reference). All of this is in the end is taking for granted the muons own clock and its proper time of which i'm not sure we've investigated. . . how does a muon keep track of time internally? This may be your thread, but your latest post moves the goalposts. Before you can discuss time in universes we are not in, you have to prove that the time in these universes is the same as time in out universe. Difficult since we have not yet arrived at a definition of time in our universe. Sorry. . . I was just playing a bit loose there with the terminology and positions from a sort of naive perspective.
  5. There is no centrifugal force when seen from your inertial frame of reference.
  6. At some point the whole thing is at rest then at a later time it's moving at a constant linear and angular velocity with respect to its center of mass. Thusly, there wasn't actually any conservation of angular momentum or energy because work was done (in this case both linear as well as rotational work). Energy was not in fact conserved if this bolt went from not moving to moving. If you are truly to do this correctly you CANNOT be ignorant to what frame of reference you are in whether inertial or in the rotating frame of reference. Further, fully analyze it from the inertial frame of reference then move into the non-inertial one with mathematics to back up your conclusions.
  7. If it doesn't work when seen from an inertial frame of reference then it doesn't work at all. The only force that can be utilized is the one that is actually accelerating you. Fictitious force only arise and are present in non-inertial frames of reference because mathematically we attempt to treat an accelerating frame of reference as if it actually is at rest so we have to make up other forces to give rise to the phenomenon we observe while remaining at rest in that non-inertial frame of reference. Those forces which do not disappear after we switch frames of reference from say non-inertial to inertial (centripetal force for example) are the only real forces that you can do anything with.
  8. If you make a spacetime diagram of this situation in which one twin remained inertial while the other had a device to measure that they flipped frames of reference (remember it's relativity of inertial frames of reference not relativity of NON-INERTIAL frames of reference) then with a instantaneous turn around the non-inertial twin would notice the other twin actually jump ahead in time in a way the other twin (inertial one) would not see. If you plot the diagram you'll notice the time loss as a missing triangular section if I recall. No, both WORLD LINES cannot be treated entirely as the same as the moving twin CHANGES frames of reference half way through his journey (his proper time). So it isn't symmetric just as if a car drives away and comes back we know it was the car that accelerated (changed inertial frames of reference) as it was not the person given they both had accelerometers. If they both remained inertial then they would never meet back up again and if they were both non-inertial then their accelerometers would have noticed the inclusion of some force fictitiously into each of their respective frames of reference but the person on the ground never noticed such inertial forces arise so the only conclusion is that the car was moving, ergo it WASN'T symmetric. Why is this so hard to understand when you literally can go into a parking lot and forget about special relativity to then show this to be the case. Remember that special relativity has to simplify down to classical physics in the low speed limit. Also, acceleration is not relative in the sense that velocity is or inertial frames of reference are just as in CLASSICAL PHYSICS or in GALILEAN SPACETIME. In special relativity (as in classical physics) it isn't relative whether you are ACCELERATING or are ROTATING. We can disagree the magnitude of said quantities but whether you are or are not accelerating is not frame dependent but can rather frame independent. @michel123456 Do you understand that the postulates of special relativity are: 1. All inertial frames of reference are to be treated as equivalent in that the laws of physics behave the same in any inertial frame of reference. 2. The speed of light as measured from any arbitrary inertial frame of reference in free space is constant. This would mean that if you had a ANY non-inertial motion then by definition we could detect it and know that we are in a non-inertial reference frame because these postulates wouldn't apply. Further, this would also mean the situation of one non-inertial observer compared to an inertial one (the twin paradox) would mean by these postulates that their world lines COULD NOT be treated symmetrically or in other terms equivalently as if the non-inertial reference was inertial. AGAIN, the postulates are not, \( 1^{*} \). All frames of reference have the laws of physics behave the same within them. \( 2^{*} \). The speed of light as measured from any frame of reference in free space is constant. You seem to be under the delusion that the starred ones are what define special relativity when in relativity it's the un-starred ones.
  9. I must supremely apologize then. I must have missed some important context involved when I abruptly popped in here. Stated differently there is no relativity principle for non-inertial frames of reference in classical or relativistic physics.
  10. A theory such as special relativity or general relativity can be a successful well understood mathematical/theoretical and applied theory of how the world works. Yet we could still disagree on philosophical interpretations of the relationship of our naive realism and previous theories with their accompanying previous ontologies to this specific theory (as well as fully interpreting the theory itself). Take the discussion of proper mass and relativistic mass and ask the legitimate question of whether one/both/neither of these newer concepts in special relativity would match up intuitively/ontologically (philosophically) to the classical physics concept of inertia (mass). Is relativistic mass the relativistic counterpart to inertia or is this a false comparison? This is a legitimate question but it doesn't really come to much difficulty when it comes to actually applying said theory if you had a case to make that we applied it, expected a certain result but got the wrong one, but under a different interpretation the experimental results could be construed to be correct then i'd agree there is something contentious. . . i'll await for you to actually propose this. In the history and philosophy of physics the discussion of what forces are as well as whether we should even accept action-at-a-distance ones wasn't settled with Newtons Principia but this philosophical side discussion didn't stop us from applying successfully the mathematical results there in for generations. You just said your biased. . . Which is technically what the GALILEAN transformation already did in CLASSICAL physics but I do not see you screaming at the top of lungs about that and how it must be a perspective thing. Classical physics did the same thing of relating certain quantities in one frame of reference to that of another but they were no less real with respect to those frames of reference. Be careful with your language here. . . novice. . . when you say STOP it's implied you mean non-inertially accelerate or change reference frames so that they entered the specific one in question. Obviously if we go to classical physics in which a person who was moving with respect to our frame of reference then suddenly de-accelerate to enter our frame of reference. . . they aren't moving any more. . . cause they stopped with respect to our frame of reference. . . so if you ask whether the non-moving observer is moving then clearly no. . . because they aren't moving. To be length contracted or appear as such from other frames of reference the object in question would have to be moving. Velocity is a real effect. . . but it's frame dependent on whether it arises and you won't see the same thing from every frame of reference nor could you claim that one particular velocity was more real or not or even declare that he is actually at rest when in other frames of reference he is moving. If this was purely a perceptual effect then we would think this wouldn't be accompanied by clear dynamical and kinematical issues involved with taking measurements. . . course you could mathematically reproduce this understanding with a classical theory of literal length contraction (as well as a counterpart one with no length contraction but finite speed of perceptual effects) and compare. . . to you know. . . show who is right.
  11. That's fine. . . simple mistakes pail in comparison to those regarding our fundamentals.
  12. In the description is declares that it's a row of dice moving. Not a single (die) pictured at different times while it was moving if I recall correctly.
  13. How about you go through the mathematics and create an image plane with the relativistic object having its light happen to reach some focus then figure it out. It's difficult and perhaps not actually correct to analyze some image analysis as has been given as we do not know what the units were nor whether your naive perceptual decision on what is longer is truly correct. Should the image of a cube appear larger than it should in the way you claim or is this not what special relativity would predict optically? Remember, no "I think it would look like this," just do the mathematics or perhaps wait for some one competent in that respective to show it in a simplified situation. A simple imaging plane and a focus will construe the image like that as objects farther to the left will appear more scrunched together i'm assuming. . . we're talking about what you would see optically. In fact. . . just you wait as i'll perform the some mathematical investigation into this but derived via some simple vector mechanics with objects being focused unto an imaging plane with a focus. Then we can compare the images showing that those objects farther away parallel wise to the imaging plane do seem to have their distance scrunched up even if we happen to possess an equally dispersed series of lines in reality. Glad you admit your fault and you must please understand that you should not use your intuition as if it's a judicial gavel of physics as even in CLASSICAL PHYSICS with optical imaging i'm willing to bet we could both make similar mistakes in thinking if we didn't actually do the proper mathematical preliminaries to derive how things would actually play out. I'll attempt to get back to you as soon as possible for the classical then the special relativistic case with all proper mathematical foundations. I'll be using equally spaced constant velocity rods then for both the classical as well as the relativistic to compare.
  14. You would think this if you didn't consult the spacetime interval in which \( s^{2} = (ct)^{2} - x^{2} = (c\tau)^{2}\). NOTE that the traveler happens to have a longer path through spacetime and together with the objectively long path they traveled in space some of that distance in SPACETIME that they happened to traverse has some of that temporal component eaten up by the distance they traveled. The spacetime interval for the person at rest is: \[ \tau = t_{person at rest} \] For the twin who (because he was non-inertial) was objectively traveling a longer path through spacetime they started and ended the journey at the same spot yielding in terms of the rest frame time \( \tau \) or it took \( \tau \) time for them to leave then come back: \[ (c\tau)^{2} = (ct_{traveler})^{2} + x^{2} \] They traveled objectively some certain distance \( x \) and using your knowledge of pythagorean theorem you notice that the length of the one side (the time by the traveler) couldn't exceed the length of the two others. Objectively given they traveled away there was no way the time of the traveler could in fact exceed or even equal that of the time given by the clock at rest if it must abide by special relativity and likewise the spacetime interval. \[ t_{traveler} \neq \tau \] @joigus Did I do this right? Always bound to come across somebody like this on any forum. . .
