Sylvanshine
then spent some time trying to feel the fact that his personal body
was traveling at the same speed as the craft he was inside. On a
large jet it felt like merely sitting in a loud narrow room; here at
least the changes in the seat’s and belt’s pressures against him
allowed him to be aware of movement, and there seemed to be some
security in the physical candor of this, which partly offset the
fragility and spatter-potential of the sound of the propellers, which
Sylvanshine tried to think of what the props sounded like but could
not except as a gnawingly hypnotic rotary hum so total that it might
have been silence itself. A lobotomy involved some kind of rod or
probe inserted through the eyesocket, the term was always ‘frontal’
lobotomy; but was there any other kind?
The
non inertial frames of reference are those that move with aceleration
and that is why an observer would be able to see how a motionless
body gets aceleration. Newton Laws are not applicable to non inertial
frames of reference, except if you add unreal forces called
fictitious forces.
In
good planes, when you are flying you don´t feel any sort of
movement, only the noise, as stated in the text by David Foster Wallace (such a great
writer unfairyly critized as too officially postmodern; I am very sad
about the fact that there will not be any new books written by him),
because they are (the good planes, I mean) inertial frames of
reference, in other words, they move with constAnt velocity.
