• Re: Mutual "length contraction" in Euclidean geometry ...
  PD, why are you dodging the question. I have *requested* you to write
  out an invariant 4-vector for the steel rod in question. Why can't you
  do that? Then you have to simply show that the term "length" is a
  *projection* of this invariant 4-vector. We could then discuss whether
  the SR notion of "length contraction" is a physical effect or just a
• Re: Don't talk to Aliens Or God! Observation...do you see any other earths or universes? What, he had no room for
  another earth? Couldn't find another sun??
  And why do you keep editing my Newsgroups, are you insane?

• Re: Electtron Microscope This is correct. Science is all about pushing the limits of defined truth to
  new levels.
  Relativists like smiffy believe everything is already known because Einstein
  discovered it.

• Re: Don't talk to Aliens Or God! Yes, he observered his theory didn't fit, the math wasn't in the science, so he got himself a 'shoehorn'.
• Re: Photons have mass and variable speed Deer fuckwit:
  Momentum is defined as mv.
  Velocity is defined as v = dx/dt
  Acceleration is defined as a = d2x/dt2
  Distance is x = 1/2 at^2 or x = vt.
  KE = 1/2 mv^2, the integral of momentum.
  That means that if you add up all the pushes that take place
  in time tiny dt you have used energy to accelerate the mass m.

  "Best information"??? Get your facts straight..the 'best information' at the time
  was that the age of the Earth was 75,000 years old. That was the belief of the scientifc
  community at that time.
  Since he didn't 'agree' with the best information, he found one nut to agree with him.
• Re: The Impossible Concept of Mutual Time Dilation An idiot, is one that doesn't learn from his mistakes, Seto.
  Observation and experiment show you to be wrong.
• Re: An experiment that was never done !!... Don't change the subject diaper. 'f = c/lambda' IMPLIES that f is the rate of
  wavecrest arrival. NOTHING ELSE!!!!
  By a grating? I have provided the correct equation for the simple case.

  I gather you are referring to 'frequency combs', in which generated microwaves
  beat with IR EM.
