Poetry · The Einstein Problem

On the Einstein

for David Smith, who played with shapes

I.

A retired man in Yorkshire

cuts kites from cardboard,

eight of them, glued edge to edge—

not solving, just seeing

what fits.

 

What fits

is everything.

II.

For sixty years the mathematicians asked:

can one tile cover the infinite plane

and never repeat?

 

Twenty thousand shapes said yes,

then a hundred,

then six,

then two (Penrose, elegant, golden),

and finally—

 

a hat.

 

Or maybe a t-shirt.

Opinion differs.

III.

The hat needs its mirror.

Fourteen percent of tiles face the other way,

like a crowd where one in seven

is left-handed,

looking at the same world

backwards.

 

But then came the spectre—

curved where the hat was straight,

and strictly chiral:

it refuses its own reflection.

Every tiling uses one hand only.

 

One shape.

No mirror.

No repetition.

Forever.

IV.

Here is what I love:

 

Not the proof

(though the proof is beautiful),

 

not the hierarchy of metatiles

(though the recursion is familiar),

 

but that he wasn't looking.

 

David Smith was not solving

the einstein problem.

He was playing.

 

A photoprotein is a poem

that hasn't been read yet.

A hat is the answer to a question

you didn't know you were asking.

V.

The Penrose tiling speaks in φ—

golden ratio, Fibonacci,

the minimal irrationality

that bends periodic order

into quasicrystalline light.

 

The hat speaks in something else.

Not φ. Not algebraic at all,

or algebraic in a way

we haven't named yet.

 

Different accent.

Same language:

one rule, infinite consequence.

VI.

Twenty thousand four hundred twenty-six.

One hundred and four.

Six.

Two.

 

One.

 

The history of aperiodic tiling

is a history of subtraction.

Each decade removes a tile

until nothing is left

but the shape itself,

alone on the table,

covering everything.
