Day Seventeen
CAPICHE
I
mix my imagination with
your
explanation of everything else
she
sat there cutting pentagons
out
of a leatherette cloth
the
lady sitting cross-legged on
the
floor next to her began to
sew
the shapes together
how
many pentagons do you need
to
make a football I asked them
we
need sixty corners one of them
replied
without looking up
City
get a lot of corners but hardly
ever
score from them on the other
hand
they often can't defend them
I
used my imagination and mixed
the
knowledge they gave me with it
so
that's about twelve pentagons I said
but
Euler 'the ruler' had already figured
it
all out F+C-E=2 for many shapes
that's
faces are F corners are C and the
number
of edges are E capiche

The modern soccer ball has 32 panels of leather or synthetic plastic tightly stitched together. Twenty of these panels are hexagons and 12 of them are pentagons. The hexagons and pentagons are equally important as they fit together like a puzzle to form a perfectly spherical shape
