Einstein referred
to
this work
as
"an excellent
presentation
of the
subject"
("eine vorzügliche
Darstellung
des
Gegenstandes").
[2]Petzoldt 1914,
which
is
more
concerned with
expounding
the
philosophical
foundations
of
relativity theory
(from
a
Machian
standpoint)
than with
presenting
an
overview of the the-
ory.
The
paper
also contains
a
discussion of the "clock
paradox"
which
is
erroneous,
as
Ein-
stein
pointed out to
its author
soon
after
publication
(see
Einstein
to Joseph
Petzoldt, 14
April
1914).
