- Well, Petr Beckmann sometimes still posts to usenet, but often flame
- wars result, so I don't know if he still does. Beckmann and I have
- tangled, and the results weren't pretty.
-
- Beckmann has written a very nice non-technical book on the history of
- pi, a very nice technical book on the polarization of electromagnetic
- waves, and in my personal opinion, a not very nice book on Galilean
- Electrodynamics "Einstein plus 2". Beckmann claims (and I am trying to
- be as fair as I can be here) that Occam's razor of using the simplest
- theory necessary to explain the data is not being used with general
- relativity. He uses what he considers a simpler theory (others
- disagree on which model is "simpler") that includes abberation and
- time delay in the propagation of light. Beckmann claims that this
- theory gives the same results as relativity, but only gives a
- derivation for the example of precession of mercury's orbit. My
- disgreement with Beckmann was when I calculated that his theory gave a
- different value for the deflection of starlight, but my calculation
- was incorrect. Beckmann's book is incomplete since he never provides
- any evidence that his theory gives the same answer as the other tests
- of relativity (i.e., the shapiro delay).
-
- Beckmann has stated that his theory does not allow for gravational
- radiation from orbiting neutron stars, but the pulsar PSR 1913+16 is
- losing energy at the exact rate predicted by GR through gravational
- radiation, so for me, is a fatal flaw for Beckmann's theory.
- Beckmann has not answered my e-mail on this point.
-
- #Does anyone know about whether the papers published by this group have any
- #validity in the general physics world?
-
- I would venture to say that the majority of professional physicists
- have never even heard of the book.
