In case you missed Wednesday night's sold out performance of the
"hottest math show in town," Fermat's Last Theorem: An
Exploration of Issues and Ideas, here's a review that appeared in
today's San Francisco Chronicle (July 30, 1993):
1,000 MATH BUFFS LEARN WHY THEOREM ADDS UP
By Steve Rubenstein, Chronicle Staff Writer
The number 1,000 may not be large, as numbers go, but it was big
enough to stun the world of mathematics.
One thousand is the number of people who showed up Wednesday
night to attend a math lecture, of all things, at the Palace of Fine Arts
Theater. Never before had so many people sat so quietly and
scratched their heads so often.
"One thousand people," said an amazed mathematician. "That's a
one followed by three zeros."
They came to find out about Fermat's Last Theorem and why it is
such a big deal. Ever since a Princeton mathematician announced
last month that he has solved the 350 year old problem, people have
been wondering why it took so long to crunch a few lousy numbers.
The Bay Area's top mathematicians, brought together by the
Mathematical Sciences Research Institute of Berkeley, rented the
hall to explain. Hardly anyone expected more than a few dozen
curious math hounds to show up.
Instead, the lecture sold out almost immediately. Scores of math fans
without tickets were turned away, including professors from Vienna
and Modesto. Scalpers were working the front door, peddling the $5
tickets for $25.
There were official souvenir programs. There was a snack bar, with
math snacks. There was a musician singing funny math songs. It was
a night to remember.
"We're not selling a lot of wine," said the women at the snack bar.
"People want to keep a clear head tonight."
The speakers were under strict orders to keep it simple. Remember,
there are laymen (and women) out there.
Fermat had kept it simple. He said the the equation X^3 + Y^3 = Z^3
has no solution in whole numbers. That was in the 1600's, and it was
so simple that no one could figure out whether he was right until last
month. [The insert accompanying the article says: "The 350 year old
mathematical mystery says that equations of the form... X^N + Y^N
= Z^N ... have no [whole number] solutions when N is a positive
whole number greater than 2. ..."]
One by one, the mathematicians on the bill stepped onstage and
began keeping it simple.
The first speaker [Bob Osserman, with Bill Thurston in a supporting
role] said Fermat's theorem had something to do with right triangles.
He flashed pictures of triangles on an overhead projector.
Mathematicians are never far from an overhead projector.
The next speaker [Lenore Blum] said it had to do with cubes of wood,
and she tried to show that you cannot place three giant cubes on a
balance beam so that two of them balance the third.
Up next was a fellow [Karl Rubin] who sad that Fermat's theorem is
all about elliptic curves, and that all elliptic curves are modular. No
one disputed it.
Finally came Ken Ribet, a wistful world-renowned expert who almost
cracked the problem himself a few years ago and sounded like he
wishes he had kept at it. He said the theorem really has to do with
"Galois representations, Iwasawa Theory, Euler systems and
congruencies among modular forms."
The laymen (and women) nodded.
[And John Conway's finale brought down the house.]
In between the mathematicians, piano man Morris Bobrow took the
stage to pound out funny math songs, including one that rhymed
"sure as shootin'" with "Isaac Newton." He did not use the overhead
projector, and got the most applause of all.
When it was over, mathematicians said they are pretty sure that the
Princeton guy, Andrew Wiles, is right, but not absolutely. The math
community has not reviewed the entire 200-page solution yet.
Math professor Joe Buhler, of Reed College in Portland, Ore., said
Wiles's proof "seems to follow a plausible line of reasoning.
"It is elegant and beautiful, and it has a feeling of being eternally
true," Buhler said. "But it is possible to be deceived by truth and
The non-mathematicians, for whom it had been kept simple, said
they surely received a lot of math for only $5.
"I don't understand it." said one fellow, munching elliptical pretzels
from the math snack bar. "But you don't have to understand
