letter
was
written
as a reply

Maric,

(Vol.

[4]Maric was
facing
her
final examinations
for
the
Diplom
at
the ETH at
the
end
of
July
(see
Ein-
stein to Mileva Maric, 22
July
1901
[Vol. 1,
Doc.
119]),
and
was
pregnant
with “Lieserl”
(see
Einstein
to Mileva
Maric,
28
May
1901
[Vol. 1,
Doc.
111]).
[5]In a
letter to
Paul
Drude,
Einstein
had formulated
two
objections
to
Drude’s
electron
theory
of
metals
(see
Einstein to Mileva
Maric,
4
June
1901
[Vol. 1,
Doc.
112]).
See
Vol.
1,
Doc. 114,
for
more
on
Drude’s
reply
and Einstein’s
negative
reaction
to it. Drude
(1863-1906) was
Professor of
Physics
at the
University
of
Gießen and editor
of
the Annalen
der
Physik.
[6]Maric’s
pique
at
Ludwig
Boltzmann
(1844-1906),
Professor
of
Theoretical
Physics
at
the Uni-
versity
of
Leipzig, may
have been due
in
part to Boltzmann’s
apparent
failure
to
respond
to
a
paper
that
Einstein
had submitted
to
him
some
months
earlier, a
paper
which
Maric
considered
“very
im-
portant”
(“sehr bedeutend.” See Mileva Maric to Helene
Savic,
20 December 1900
[Vol. 1,
Doc.
85]).
[7]Einstein
was
looking
for
a
position
with
an
insurance
company (see
Einstein
to Mileva
Maric,
28
May
1901
[Vol.
1,
Doc. 111) and had
applied
for
a
teaching
position
at
a
technical school
(see
Einstein
to
Director’s
Office,
Technikum
Burgdorf, 3
July
1901
[Vol. 1,

[8]Zorka
Maric (1883-1938) and
parents
Milos (1846-1922) and
Marija
(1847-1935) lived in
Újvidék, Hungary (present-day
Novi
Sad, Serbia).

[10]Heinrich
Friedrich
Weber (1843-1912),
Professor of
Physics
at the
ETH, was one
of
Maric’s
examiners for
the
Diplom.
Most
probably,
Maric
was studying
Einstein’s notes
on
Weber’s lectures
on thermodynamics, as
well
as on
topics
in
electricity
and
magnetism
(see
H.
F.
Weber’s Lectures
on
Physics,
December
1897-June
1898
[Vol. 1,
Doc.
37]).
[11]Einstein
was living
in
Winterthur,
where
he
had
been
offered
a
position as
a
substitute teacher
in mathematics until
mid-July
(see
Einstein to Mileva
Maric, 15
April
1901
[Vol.
1,
Doc.
101],
[12]A
diminutive
presumably
for
“Geige.”
[13]Maria
Popova
(1878-?)
had enrolled
as a
student at the
University
of
Zurich in fall 1899
(see
no.
12838 in
Matrikelbuch, SzZSa,
UU

She lived at Plattenstrasse 50 in
the
same
house
as
Johanna Engelbrecht (1855-1940) and Maric
(see
their
residence cards, Einwohnerkontrolle, SzZ-
Ar).

Monsieur,
Permettez moi de
vous présenter quelques
remarques
au
sujet
de
la
note
que
vous
m’avez fait la
faveur de m'adresser.[2] Il est tout à fait exact
que
le
vecteur
O
n’est autre
que
le vecteur
m
de
Minkowski
que
vous
désignez
par
la lettre £. Je le
croyais
évident. Mais
dans
mon
travail la
l.[3]
£
désigne
le vecteur
£
de Lorentz.
C’est bien
ce que je
dis à la
p.
193:
Allerdings
hat
der Vektor
Q
nicht
die
Bedeutung
der
magnet.
Kraft
(pour
Lorentz
bien
entendu et
non
pour Minkowski)[4]
