Mitteilungen
18
(1916):
47-62. Published
after
24
August
1916 (see
Einstein
to
Michele
Besso, 24
August 1916,
in
which Einstein
men-
tions the
completion
of the
paper).
[1]Einstein lectured
on
the
topic
of this
paper at
the
meetings
of
27
October and
10
Novem-
ber
1916
of the Deutsche
Physikalische
Gesellschaft
(see

Physikalische
Gesell-
schaft. Verhandlungen 18
(1916): 367,
368).
Some of the results of this
paper
were
earlier
published
in
Einstein
1916j
(Doc.
34).

[8]Commenting on
this
paper
in
a
letter
to
Besso,
Einstein
emphasized
this
point
in
partic-
ular
(see
Einstein
to
Michele
Besso, 24
August 1916).
[9]"u"
should
be "v."
[10]Einstein
1917c,
the
republication
of this
paper
in
Physikalische Zeitschrift,
has
"Hypo-
these"
instead of
"Hypothesen."

[13]Einstein first applied
methods that
he
had devised for
studying
Brownian motion
to
the
radiation
problem
in
Einstein 1909b and Einstein 1909c
(Vol. 2,
Docs.
56
and
60). He
used
them
again
in
his work with
Ludwig Hopf,
Einstein and
Hopf
1910b
(Vol. 3,
Doc.
8),
and with
Otto
Stern,
Einstein and Stern 1913
(Vol. 4,
Doc.
11).
See
also Klein
1964
for
a
historical dis-
cussion.
[14]In
Einstein 1917c the
following
words
are
inserted between "des"
in
the
previous
line
and "wir": "Moleküls besonders
in
Rechnung gezogen
haben,
werden."
[15]This
use
of the
equipartition
theorem
in its
most general
sense
goes
back
to
Einstein's
first
paper
on
Brownian
motion,
Einstein 1905k
(Vol. 2,
Doc.
16).

[17]Kurd
von
Mosengeil's
dissertation
was
posthumously published
as
Mosengeil 1907.
It
was
prepared
for
publication
by
Max
Planck,
who had been
Mosengeil's supervisor.
[18]Einstein
had
always recognized
that theoretical
results
might
be,
and often
were,
much
more
general
than their
derivations seemed
to
indicate.
See, e.g.,
Einstein 1903
(Vol.
2,
Doc.
4)
and Einstein
1904
(Vol. 2,
Doc.
5).
[19]"coscp"
should
be
"coscp'."
[20]"yv" should be
"Xv."
[21]Thirty
years
later,
Wolfgang
Pauli drew attention
to
these
significant
remarks
in
a
paper
written for Einstein's sixtieth
birthday.

Pauli
1949, in
particular
