car les =C3=A9quations de la transformation de Lorentz sont, dans le cas o=
=C3=B9=20
le r=C3=A9f=C3=A9rentiel R' se d=C3=A9place dans le sens des x positifs par=
 rapport =C3=A0 R:
x'=3D(x+Vo.t)/sqrt(1-Vo=C2=B2/c=C2=B2) =3D> t=E2=80=99 =3D t/=CE=B3
y'=3Dy =3D> t=E2=80=99 =3D t
z-=3Dz =3D> t=E2=80=99 =3D t
ce qui est incoh=C3=A9rent.

x=E2=80=99 =3D x
y=E2=80=99 =3D y
z=E2=80=99 =3D z
car
x=E2=80=99 =3D x =3D> t=E2=80=99 =3D t
y=E2=80=99 =3D y =3D> t=E2=80=99 =3D t
z=E2=80=99 =3D z =3D> t=E2=80=99 =3D t
 est coh=C3=A9rent.
