MatheMUSEments
By the Numb3rs

Muse, April 2006, p. 43.
"We all use math every day." That's a line
you might hear in math class or see at a science museum. You don't
expect to find a TV crime series that celebrates it. Yet millions
of people hear this line every week at the beginning of the popular
CBS show Numb3rs, which features a young math professor as
a crime fighter.
Charlie Eppes, played by David Krumholtz, uses math
to help his older brother, Don, who's an FBI agent, solve crimes.
For example, he uses a mathematical equation to identify a killer's
location by working backward from the crime scene locations. Or he
solves an undecipherable numerical code left at the sites of train
wrecks to discover who's causing them.
Math comes up in other ways, too. In one show a man's
daughter is kidnapped because he is about to solve Riemann's hypothesis,
sometimes called the most difficult unsolved problem in mathematics,
thereby winning a $1 million prize.
For many people, part of the fun of watching the series
is to see if they can spot mathematical stuff—games, puzzles,
books, calculators, posters—in Charlie's cluttered office. They
also listen for references to mathematical concepts and famous mathematicians
that often have nothing to do with the plot but still say something
about a mathematician's life and interests. The see-through blackboards
are pretty cool, too.
The show's producers and writers go to a lot of trouble
to find stories that involve math and to check with experts to make
sure that they use math correctly. It takes about 2 months to go from
an idea to a final script.
Just before episodes are filmed, the actors sometimes
get written explanations of the math concepts that will come up—but
they don't always read them. Krumholtz used to have a hand double
who wrote his equations for him, but more recently the actor has begun
to write them for himself.
A team of teachers also gets a preview of each script
before it's filmed. Inspired by a program's math content, they prepare
classroom activity sheets, which are made available at www.cbs.com/primetime/numb3rs/ti/activities.shtml on the Monday before each new show is broadcast. You can also check
out Numb3rs blogs. The math department at Northeastern University
in Boston, for example, provides background information on topics
the shows touch on, such as digital image processing or blackjack
strategies, at www.atsweb.neu.edu/math/cp/blog/.
Of course, no real mathematician could possibly know
as much as Charlies does about so many different areas of mathematics.
But you expect TV stars to be larger than life—and those CSI
guys sure can figure out a lot from one "epithelial"!
