Wrong Numbers
The September
23rd loss of NASA's Mars Climate Orbiter was avoidable.
As the $125 million dollar spacecraft
began to circle Mars, attempting to
become the first interplanetary weather
station, its onboard navigational system
malfunctioned. The spacecraft hit
the Martian atmosphere at the wrong angle
and burned up. Why the
malfunction?
Wrong numbers... NASA claims they're
overworked and underfunded, neglected
to check the units of measurement used
by one of their many contractors, and
when it came time for the spacecraft to
enter into orbit, it couldn't process
the conflicting measurements of International
Units (e.g., meters and kilometers) and
the quaint, isolationist American system
(e.g., feet and miles). Well,
considering
America's conflicting, self-inflecting,
degrees of stubbornness regarding most
things, maybe the malfunction wasn't so
uncommon after all.
An Ice Age notational
artifact.
Though
dedicated
researchers, such as Alexander Marshack (The Roots of
Civilization, 1972 &
1991), have advanced our understanding of the cognitive
abilities of early modern humans,
linguists
and anthropologists have failed to
uncover any evidence of a prehistoric
numbering system or any remnant names
for numerals beyond 'three'. It
appears our prehistoric ancestors counted "one,"
followed by "two," and then used some
variation of "a whole bunch!" Though
the concept of number was undoubtedly
recognized early, as evidenced by
notational tally counts from around the
globe, imparting names to numbers
appears to have been a rather late
development.
The renowned historian of
mathematics, Dr. Otto Neugebauer, drew
attention to the general inability of
most ancients to name their numbers by citing
the "Spell for Obtaining a Ferry-Boat"
from the Egyptian Book of the Dead, a
section which was derived from material
contained in the earlier, so-called
"Pyramid Texts" of the Old Kingdom
period.
The section tells of an underworld
ferryman who asks: "Did you bring me a
man who cannot number his fingers?"
Apparently the ability to name numbers
was usually limited to kings (or
pharaohs) and magicians (or priests).

which is widely available.]
Owing much to
the pioneering and still controversial work of Dr. Denise
Schmandt-Besserat, Professor of Art and
Middle Eastern Studies at the
University of Texas at Austin, many now
understand the emergence of the
earliest writing system (Sumerian
cuneiform)
to have developed from an archaic
counting system which used tokens and
identifying character marks. According
to Schmandt-Besserat, then, the act of
numbering gave rise to the associative
process of assigning character marks to
communicative ideas and language. It
may be assumed that the preliterate
Sumerians
"named" their numbers, but those
"words" remain unknown. [For more on

While today's
graphic expressions of numbers are traced through Hindu and
Arabic characters, and the Classical
Greeks
are widely credited with having
initiated "science" and mathematics, in
actuality both were extremely dependent
on the continuation of the archaic
counting
system of the preliterate Sumerians.
The Sumerian culture, through conquest
and population influx, is now divided
into such "historical" periods as Akkad,
Ur, the Hammurabi Dynasty or "Old
Babylonian," Cassite, Assyrian, Persian
or "Neo-Babylonian," contemporary
Iraq, and the like. Very early,
probably from the beginnings of numeration, there
were conflicting systems of counting,
as evidenced by the diverse base-systems
of extant cuneiform texts. We know
of the popularity of the sexagesimal
system, as it survives in our 60 minute
hour and 360° circle, but what is not
widely known is that this awkward system
was only used in astronomical
calculations, and many other systems
(e.g.,
based on 10, 5, 4, etc.) were used in
commonplace numbering. It's most
confusing to comprehend today, it must've
taken a "king" or "magician" to understand
such in its day, and the difficulty
seems to survive in the work of some of
the private contractors hired by NASA!
[For a thorough (though somewhat
"out-of-date""
discussion of terms and
periods, see: Science Awaking II
by B. L. van der Waerden, 1974,

Babylonian
Astronomy."]
It remains
folly
to suggest why the Sumerian culture and their later offshoots
elected to utilize a numbering system
based on 60. Some have advanced the
origin of the 60-base system as a division
of the measurement of silver, as a
mana was divided into 60
shekels, but this is "putting the cart in front of the
horse," and the answer remains
elusive.
What is plain and demonstrable is the
biological happenstance of our species
possessing ten fingers and choosing 10 as
our common, or "base," counting
system.
The base-10 system developed,
seemingly independent in Sumeria, Egypt,
and elsewhere, the early Greek
mathematicians continued the confluence
of different systems (e.g., 60 for
astronomy and 10 for commonplace
notations),
and this diffused eastward to
Arabia, India, and beyond, which later
returned as "our" notational system.
Yup, the world keeps getting smaller!
What Alexander
the Great attempted, the Romans idealized, the Catholic
church nearly realized, and Napoleon
Bonaparte
foolishly struggled for--a
uniting of us all--is ultimately
a grand and hopeful goal. Fortunately, so far,
when despots, governments, and religions
make the attempt it fails, because
subtle distinctions proudly separate us
and major commonalties enjoin us. It's up
to us to define our own way in the modern
world and not be beholden to the
past. The 18th century invention
of the "metric" system has steadily united
much of our planet with its
straightforward
simplicity. Oh, except America, that
is, even though we've been told todo so
for some time now. See, we don't like
being told what to do, even if it means
crashing a $125 million dollar spacecraft,
"walking a mile for a Camel"
cigarette, and buying a gallon of milk, a quart of
beer, or a pint of booze. We don't
appreciate ...being told what to do!
Americans are Coke, McDonald's,
and Gap commercials (read: spoiled,
self-centered adolescents), and we'll
waste our money and technology as we see
fit. Got it? [Click here

The upcoming
Mars
Polar Lander, scheduled for December 3rd, 1999, is
susceptible to the same software problems
as the Climate Orbiter. NASA has
promised it will correct everything,
...mumbled
something about how their
immediate mission will continue without
the Climate Orbiter, and is trying to put
the best face on a really embarrassing
event. NASA? Forget embarrassment...
Birds have feet as well as wings...
Get back to work!
