TURDS. THEIR PLACE IN SOCIETY.

Theoretically, the null result of the Michelson-Morley experiment can be obtained by assuming that: (A) The speed of light varies with the speed of the light source (c'=c +v); the principle of relativity is correct; there are no miracles (length contraction, time dilation). (B) Einstein's 1905 light postulate (c'=c) is correct; the principle of relativity is correct; there are miracles (length contraction, time dilation). There is no reasonable third alternative. That is, Newton's emission theory of light with its constitutive equation c'=c+v is the ONLY alternative to special relativity. Moreover, the emission theory is TRUE and special relativity FALSE unless one finds natural that a long train can be trapped inside a short tunnel, an 80m long pole can be trapped inside a 40m long barn and a bug can be both dead and alive: http://www.youtube.com/watch?v=VSRIy...related&search http://math.ucr.edu/home/baez/physic...barn_pole.html "These are the props. You own a barn, 40m long, with automatic doors at either end, that can be opened and closed simultaneously by a switch. You also have a pole, 80m long, which of course won't fit in the barn. Now someone takes the pole and tries to run (at nearly the speed of light) through the barn with the pole horizontal. Special Relativity (SR) says that a moving object is contracted in the direction of motion: this is called the Lorentz Contraction. So, if the pole is set in motion lengthwise, then it will contract in the reference frame of a stationary observer.....So, as the pole passes through the barn, there is an instant when it is completely within the barn. At that instant, you close both doors simultaneously, with your switch. Of course, you open them again pretty quickly, but at least momentarily you had the contracted pole shut up in your barn. The runner emerges from the far door unscathed.....If the doors are kept shut the rod will obviously smash into the barn door at one end. If the door withstands this the leading end of the rod will come to rest in the frame of reference of the stationary observer. There can be no such thing as a rigid rod in relativity so the trailing end will not stop immediately and the rod will be compressed beyond the amount it was Lorentz contracted. If it does not explode under the strain and it is sufficiently elastic it will come to rest and start to spring back to its natural shape but since it is too big for the barn the other end is now going to crash into the back door and the rod will be trapped in a compressed state inside the barn." http://hyperphysics.phy-astr.gsu.edu.../bugrivet.html "The bug-rivet paradox is a variation on the twin paradox and is similar to the pole-barn paradox.....The end of the rivet hits the bottom of the hole before the head of the rivet hits the wall. So it looks like the bug is squashed.....All this is nonsense from the bug's point of view. The rivet head hits the wall when the rivet end is just 0.35 cm down in the hole!

heat conduction as 'vibrating atoms' is a flawed interpretation

waht he said. *ultimately, it is all mediated by radiation, but "stuff gets in the way of it." there is another mode of heat transfer, perhaps also less analyzable a la Fourier, "trasporative heat flow," when water flows over a warm object e.g. That would seem to allow transmission of information. |

Yes. According to the algebra of the theory, moving poles stretch/expand, they do not shrink/contract. Division by something less than one will increase the quotient, 2 = 1/0.5. No. According to the algebra of the theory, the _do_ shrink/contract. This is well known. Maybe you've swapped the two frames of reference. Relativity (SR) says that a moving object is expanded in the direction of motion, contrary to Baez's lying claim. That's what _you_ say. It's _not_ what Special Relativity says. All crackpot theoretical physicists are failed mathematicians. Why this verbal violence? Does it contribute anything to the argument? Han de Bruijn |

I accept any rational critism but your critism of physics seems unfounded since you seem to be ignorant of it. Scent is distributed by Brownian Motion. Yes, you are leaning on the gas form to make your way. And it takes just a tiny bit of scent vapor in the air to be detected. I suppose we could go on to challenge adiabatic type behaviors, but I'd just as soon stick to the solid form. The gas form is much more challenging. Place a gas in outer space and baboom! it distributes itself out. Place a solid in outer space and it just sits there, solid as ever. Will you extend your claim of Brownian motion onto the solid? I'm not so sure that diffusion and brownian motion are exactly the same as you are claiming. Here is a statement: 'Brownian motion is observed in molecules that are so large that they are not driven by their own thermal energy but by collisions with solvent particles.' - http://en.wikipedia.org/wiki/Diffusion I'll admit the difference is subtle and they are closely related. Diffusion does not require any temperature difference as I've attempted to discuss. Your bottle of scent can be the same temperature as the air it is in. Still, I do think that the example is a nice addition to the conversation. Yes, when you open it it may cool a bit as the scent evaporates. This is very complicated stuff and I believe that the solid example is a more simplified environment to puzzle over. - Tim |
