Remarkably, he derived all his work from two simple postulates applying to inertial frames (i.e.

### In science:

Absolute motion is not required, only the relative motion between the inertial frames is needed.
General Relativity Requires Absolute Space and Time
According to Special Relativity, each inertial frame has its own relative time.
General Relativity Requires Absolute Space and Time
One can infer via the Lorentz transformations on the time of the other inertial frames.

But τ 0µ is just a local energy ﬂow since it is deﬁned in orthonormal local inertial frames.

FIGURE 9. A quantum particle must be represented by all of the lines of its probability current. A local inertial frame only applies to the local motion of a single quantum particle.

If we consider the position 1-vector x in another relatively moving inertial frame of reference S ′ (characterized by γ ′ 0) then the space-time split in S ′ and in the Einstein system of coordinates is xγ ′ 0 = ct′ + x′ .
The Proof that the Standard Transformations of E and B are not the Lorentz Transformations. Clifford Algebra Formalism
Note that the whole procedure is made in an inertial frame of reference with the Einstein system of coordinates.

All position vectors are measured with respect to an inertial frame with its origin at the center of mass of the entire system.

The distance (33) was calculated in the local inertial frame.
Components of the gravitational force in the field of a gravitational wave
Coriolis force if one works in a frame co-rotating with the ﬂow, one can obtain the correct result from straightforward kinetic theory in the inertial frame.
Kinetic theory viscosity
As before, we work in the inertial frame that co-moves with the mean ﬂuid ﬂow at S and again consider the limit that the shear across a mean free path λ is much less than the random velocity c (i.e. RΩ′ λ ≪ c).4 We note that, since RΩ′ ∼ Ω, it is also the case that λ ≪ R.
Kinetic theory viscosity
In general δ is expected to vanish in an inertial frame as the Einstein convention works perfectly there.
Simultaneity in special and general relativity
The remaining problem is that of ﬁnding a suitable local simultaneity convention that reduces to Einstein’s in the Minkowskian-inertial frame case.
Simultaneity in special and general relativity
The simultaneity slices turn out to be the same of the inertial observers at rest in the inertial frame i.e. those that observe the rotating platform from the outside.
Simultaneity in special and general relativity
The coordinate direction pi is not a directly observable quantity as it is deﬁned with respect to coordinate grid on the curved space-time manifold. A real observable vector towards the source of light, sα = (1, si ), is deﬁned with respect to the local inertial frame co-moving with the observer.
