DOCUMENT 137 FEBRUARY 1909 157
[2]In
the
preceding expression,
as
well
as
below
in
this
document,
the
square
brackets,
which
are
in
the
original,
denote the
vector
product. Dmitry
Mirimanoff's
paper
is
Mirimanoff
1909a;
Hermann Minkowski's
is
Minkowski
1908.
Minkowski's
equation
III"a
is
adapted
from
an
equation
with the
same
number
in
Lorentz 1904b
(p.
209);
it
is
a
form of
Ampere's
law
for
moving magnetized
media. Mirimanoff
(1861-1945)
had tried
to
bring
Lorentz's
equations
for
macroscopic electrodynamics
of
moving
media into accord with Minkowski's relativistic
ones.
Einstein 1909a
(Vol. 2,
Doc.
55)
shows that this
is
impossible.
The
symbols
in the
equation
(and below)
have their usual
electromagnetic meaning, except
Q
(see
the
following
note)
and
tt),
which denotes the translation
velocity.
See
Vol.
2,
the editorial
note,
"Einstein and Laub
on
the
Electrodynamics
of
Moving
Media,"
p.
570,
for
a
discussion.
[3]In
Einstein 1909a
(Vol. 2,
Doc.
55)
Einstein shows that Mirimanoff's
vector
Q
not
only
obeys
the
same
equations as
Minkowski's |), but that it also has the
same
physical meaning
as
the latter
quantity.
The conclusion of the
paper
is
that Mirimanoff's and Minkowski's theories
are
identical. See the
following
document for Mirimanoff's reaction.

Monsieur,
Je
vous
remercie
de
votre
si
aimable lettre.
Soyez
assure
que je
serais
tres
heureux
si
l'occasion
me
permettait
de
faire
votre
Connaissance
et
tres
flatte
de
mon
cote
d'avoir
votre
visite
si
jamais
vous vous
trouviez
ä
Geneve.
Dejä
je
vous
connaissais
par
vos
interessantes
publications.
Au fond
j'attache
fort
peu d'importance
ä
mon
petit
travail
sur
les
equa-
tions de
Lorenz[2]
et
bien
que je
ne
sois
pas
d'accord
avec vous sur
toutes
les
conclusions
que vous
tirez
de cette
6tude,
je
suis
heureux
qu'elle
ait
attire
vo-
tre attention.
Je
compte publier
dans
quelque temps
une
petite
note ä
propos
de votre
"Bemerkung"
dans
laquelle
je
resumerai
tres
sommairement les
re-
flexions
que
j'ai
eu
l'avantage
de
vous
presenter
dans
ma
premiere
lettre.[3]
Aussi
vous
serais
je
tres
reconnaissant
si
vous
vouliez
bien m'adresser
un
exemplaire
de votre note
quand
elle
aura paru, pour que
je
puisse
la citer
d'une maniere
exacte.
En
vous
remerciant
encore une
fois
je
vous
prie, Monsieur,
d'agreer
l'ex-
pression
de
ma
consideration
distinguee

Mirimanoff.

[1]Mirimanoff
was
Privatdozent
in
mathematics
at
the
University
of Geneva.

A. Lorentz;
Mirimanoff
1909a.
See the
preceding
document for
more on
Mirimanoff's
work.
[3]See Mirimanoff 1909b;
Einstein's
"Bemerkung"
is
Einstein 1909a
(Vol. 2,
Doc.
55). In
his
response
Mirimanoff stated that he had
only
wanted
to investigate
the
consequences
of the
application
of the
relativity postulate
to
Lorentz's
electrodynamical equations.
