"QUESTION: I understand some basic physics, and I understand the math
behind it, but one question puzzles me conceptually. Say two objects
are moving at, say, 3/4 the speed of light moving towards each other.
How can I conceptually reconcile what is really going on there? That
is to say, the two object will really only be going at max the speed
of light relative to the other, but this seemingly makes no sense
conceptually, whereas it does make sense mathematically.
ANSWER (Expert Philip A. Stahl, 3/5/2009): Hello, Actually, the two
objects of which you speak would not even achieve c as their maximum,
but only 0.96 c. According to the appropriate relative velocities
equation. Conceptually, it is extremely difficult to understand how
this can be because OUR BRAINS ARE CONDITIONED TO THINK IN TERMS OF
NORMAL RELATIVE VELOCITIES. Say like two cars approaching each other
at 50 mph for which the relative velocity of either wrt the other is
then the simple addition of speeds, or 100 mph. The trick in terms of
relativity is the fact that c represents a fundamental limit on cosmic
speeds, not just another everyday quantity."

In the same way, in Big Brother's world, brains are conditioned to
think in terms of normal arithmetic where 2+2=4 but the trick in terms
of Big Brother's science is the fact that 2+2=5 represents The
Fundamental Truth, not just another everyday (mistaken) calculation:

George Orwell "1984": "In the end the Party would announce that two
and two made five, and you would have to believe it. It was inevitable
that they should make that claim sooner or later: the logic of their
position demanded it. Not merely the validity of experience, but the
very existence of external reality, was tacitly denied by their
philosophy. The heresy of heresies was common sense. And what was
terrifying was not that they would kill you for thinking otherwise,
but that they might be right. For, after all, how do we know that two
and two make four? Or that the force of gravity works? Or that the
past is unchangeable? If both the past and the external world exist
only in the mind, and if the mind itself is controllable what then?"
