on the basis nets and time symmetrical we measurements
everybody knows the direction of that from the past so but you
but what would be different at the time or backward
the microscopic work is invariant under time reversal if you invert the velocities and the
motion looks natural and is described my best same equations
in contrast to the microscope reverse ability macroscopic processes are usually irreversible because of the
second vowel herman i not
only the dynamics of work will address space is irreversible that's what was done on
microscopic or equilibrium systems
we gather information about the state of a system by measurements
a generic measurement skiing this sequence of that vector preparation in standing direction would assist
them and try not to read out
most measurements than classic are and basically we just of assistant
is that there might and power off time
but if we decrease the string corpora measure and then it will be less and
less is there such a week measurement is the not in a c t expensive
to large uncertainty in the measurement
in the limit we obtain the idea non-invasive measurement
imagine our system in a stationary time symmetrically equilibrium state if you measure not basically
quantity three subsequent times separated by two one and he tool
then the time reversal operation would be equivalent to swiping q one and t two
whether or not such a time reversal operation using the same measurement results can be
checked or classical and quantum mechanical
more classical and quantum measurements are non invasive inventing it or banishing straight
at the question is no problem measurement results also time symmetry
surprisingly we find but non invasive measurement results are time symmetric classic early but not
quantum mechanical this apparent time-reversed has symmetric break increasing use up and fundamental difference between
classical and quantum account
