tivistic' formulae for these two cases have been confirmed
by experiment and are described in many textbooks.
It was, however, not recognized that they are at variance
with Einstein's relativity principle extended to electromagnetic
waves."
S. 31: "In this paper the formulae for the relativistic
Doppler effect are derived without using the Lorentz
transformation (Section II). This can be done in the
photon picture of light in combination with the relativistic
modification of Newtonian mechanics applied to
detector and source. We find indeed different frequency
shifts depending on whether the observer moves or the
source. In Section III these results are compared with
those deduced by Einstein from the Lorentz transformation.
It turns out that there is practical agreement
with the formulae derived in Section II. In Section IV
the conclusion drawn from the Lorentz transformation
that a wave front `appears' tilted, if there is a relative
velocity between observer and source, is scrutinized
and found to be untenable. In Section V consequences
of our analysis for the principle of relativity and for the
Lorentz transformation are discussed."
Liefert mit dem Nachweis, daß die beim Doppler-
Effekt auftretenden Frequenzänderungen abhängig
davon sind, ob sich die Quelle oder der Beobachter
bewegen, eine grundsätzliche Widerlegung des SRT-
Relativitätsprinzips und der Lorentz-Transformationen.
- Diskutiert in Abschnitt IV (S. 41-45) die Stern-
Aberration. Sie konnte schon im 18. Jh. von Bradley
mit Annahme eines Äthers und der Galilei-Transformation,
also ohne Lorentz-Transformation erklärt werden.
Betrachtet 4 verschiedene Konstellationen von
Stern und Teleskop und stellt für die 4 Fälle jeweils die
Behauptung nach der Lorentz-Transformation und die
astronomischen Beobachtungen gegenüber (S. 43), woraus
sich klare Widersprüche ergeben, so daß die Beobachtungen
die Lorentz-Transformation widerlegen.
Weitere Argumente ergeben sich aus der Erörterung der
Doppelsternsysteme.

S. 309: "By investigating the motion of a point charge
in an electrostatic and in a magnetostatic field, it is
shown that the relativistic transformation of electromagnetic
fields leads to ambiguous results. The necessity
for developing an `electrodynamics for moving matter'
is emphasized."
S. 311: "In the present paper the concept of special
relativity, namely to substitute an `electrodynamics for

moving bodies' by an `electrodynamics for matter at
rest' combined with a prescription for transforming the
fields, is scrutinized. In Sections III and IV the motion
of a charged particle in an electrostatic and in a magnetostatic
field, respectively, is calculated in two frames
moving at a constant velocity relatively to each other.
Adopting the relativistic expressions for the transformed
fields, we obtain ambiguous results. It turns out that
Einstein's concept is only viable in very singular cases.
It is apparently necessary to develop a true electrodynamics
for moving matter, in general."
Fordert die Formulierung einer wahren "Elektrodynamik
für bewegte Materie", weil der Versuch Albert
Einsteins in der SRT, eine solche Elektrodynamik durch
eine "Elektrodynamik für ruhende Materie" und eine
relativistische Transformation der Felder zu ersetzen,
zu mehrdeutigen Ergebnissen führt, die ohnehin nur für
Spezialfälle, also nicht generell gelten. Albert Einstein
hat also keine wahre Elektrodynamik für bewegte Körper
vorgelegt.
Die Lorentz-Tranformation ist von W. Voigt nur
für den Sonderfall von konstanten Geschwindigkeiten
hergeleitet worden. Albert Einstein hat dagegen angenommen,
daß seine Formeln auch gelten, wenn sich die
Geschwindigkeit ändert in Raum und Zeit, verbunden
mit einer Vorschrift zur Transformation der Felder.
S. 324: "From the analysis in Sections III and IV it
became obvious that a solution of `Maxwell's equations
for matter at rest' cannot be made into a solution for
moving matter by applying the Lorentz transformation,
in order to obtain the fields in a moving system. It is
questionable anyway, whether this method would work
when the velocity varies in space and time, since the
Lorentz transformation is restricted to constant motion."
S. 325: "In 1890 Hertz [2] was aware of the fact that
the final forms of the forces are not yet found. In case
the open problems could not be solved, he was not even
certain that Faraday's and Maxwell's field concept is
viable at all. Having shown that the transformation of
the electromagnetic fields, as proposed by special
relativity, is not a feasible concept to establish an `electrodynamics
for moving matter', it is obvious that the
work started by Lorentz [8] and Hertz [3] should be
taken up again, both theoretically and experimentally.
It remains to be seen to what extent classical electrodynamics
will require a basic revision."
