The
Pythagoreans’ most profound discovery was a link between
numbers and the
real world: things could be described by numbers, and numbers described by things. Unfortunately, they made the
mistake of believing in something a little more extreme: that
numbers are things and that
things are numbers. And while this seemed to make sense in most cases, they eventually found that some numbers simply didn’t
add up.
Making use of their ever-so-famous
Pythagorean Theorem, the Pythagoreans found that if the two
legs of a
right triangle were both 1, then the
hypotenuse must be the
square-root of two.
“
What the hell?” they said.
The square-root of two is 1.41421356… It continues indefinitely. It
cannot be defined outside of the statement “the square-root of two” and is completely and utterly
irrational. This was a
problem, because if such a number did exist, then something in the real world must exist that is
equivalent to it. And if the basis of
human reason,
rationality, is broken (or, if
something in the world is irrational), then there must be some
irrationality to man in correspondence with
irrationality in nature.
In other words, who are
we when
we cannot be defined? And what can something
undefined really know about itself, or
anything for that matter?
Well, even though the Pythagoreans suspected the numbers
might not exist in the real world, they feared where the numbers
did exist. What if these irrational numbers were maybe some door into
chaos and
oblivion, or
signs of some malevolent god? In essence,
it scared the shit out of them, and so they simply stopped thinking about them. They didn’t
deny irrational numbers, but they wouldn’t touch them with a
ten foot pole.
This
check in knowledge has been commonplace throughout history. We constantly come to
lines that we aren’t sure whether to cross or not. The reason for this?
Pandorra’s Box. When you discover something, it doesn’t just go away. This happened in the early
20th century with nuclear weaponry, and it’s happening now with the human
genome and
nanotechnology. Will we become genetically selective, conditioning our children and oblitering the less-perfect humans? Will
nanodust be released and destroy
life on earth?
What the
future holds is hard to predict. What we
stare in the face now is not so different from what the Pythagoreans faced 25
centuries ago. The difference is: they drew a line. And though we no longer fear irrational numbers, some wonder: should we worry about this
Brave New World, or these
little robots of death?
