[net.misc] Biblical value of pi

lew@ihuxr.UUCP (Lew Mammel, Jr.) (04/04/84)

Last year I saw a videotape of a colloquium entitled, "Universality and
Singularity - Phase Transitions and Our Understanding of the Physical World".
I posted something about it at the time, but I'm mentioning it now in
connection with the "biblical value of pi".  The speaker actually had a
viewgraph of the verse from I Kings which implies pi = 3. He compared this
with a more modern numerical crudity, consisting in the assumption that the
function expressing the approach to a phase transition was quadratic.

His point was that the assumption was implicit and uncritical, and further
that it would be a mistake to deem ourselves too far superior in our
understanding of the world than the ancients.

I think there are a couple of people who lost the point. The person or people
who first brought up the whole business did not do so to sit smugly in judgement
as to what dumbshits the ancients were by equating pi to 3. The fact that the
Bible implies that pi=3 *is not the point*!
	The point is that some group was being stupid enough to want a state
legislature to pass a law making pi=3 *because it said so in the Bible!*

Thank you, Jerry.

	The explanation I had always heard for the attempt to make pi = 3 was
that it was essentially an attempt to make it easier for farmers to prepare
their tax returns.  Farmers had to estimate the amount of grain stored in
their (cylindrical) grain elevators, and, in those pre-calculator days,
multiplying something by 3.1415926... was a real pain.  The proposal was to
let them use 3 for pi in the formula for the volume of the elevator, and then
adjust the tax tables so that everything worked out more or less correctly.
However, the newspapers picked up only part of the story, screwed up a few
things, and reported that there was a bunch of dumb farmers out there trying
to redefine mathematical principles by a vote of the legislature, imposing
weird religious beliefs on the public at the same time.  Once this happened,
of course, the bill never had a chance.

	This explanation has the disadvantage that it actualy makes a certain
amount of sense, and doesn't let us make fun of a bunch of dumb farmers out
there trying to redefine mathematical principles by a vote of the legislature,
imposing weird religious beliefs on the public at the same time.  On the other
hand, I wasn't there at the time, so there may be hope after all....:-)
