[page 217, §1] [217.1.1] These observations suggest a reformulation of the controversial irreversibility problem [49, 6]. [217.1.2] The problem of irreversibility is normally formulated as:

[217.1.3] Assume that time is reversible. Explain how and why time irreversible equations arise in physics.

[217.1.4] The assumption that time is reversible, i.e.

[217.2.1] The problem with assuming ^{g} (This is a footnote:) ^{g}
Note, that this is not the same as reversing the momenta of all particles
in a physical system..
[217.2.4] This was emphasized in [49, 6].
[217.2.5] These simple observations combined with
eqs. (30) and (31)
suggest to reformulate the standard irreversibility problem:

[217.2.6] Assume that time is irreversible. Explain how and why time reversible equations arise in physics.

[217.2.7] The reversed irreversibility problem was
introduced in [49].
[217.2.8] Its solution is given by
Theorem 8.1 combined with
(30) and (31).
[217.2.9] The impossibility of performing experiments in
the past is fundamental and evident.
[217.2.10] Therefore, as emphasized in [49],
it must be assumed that time is irreversible.
[217.2.11] The normal irreversibility problem starts from an
assumption, that contradicts experiment, while
the reversed problem starts from the correct
assumption.

(30) and (31)
explains why time translations, i.e. the case
