Reed-Solomon
This morning I learned
how QR codes correct errors.
Not by hoping,
not by checking twice,
but by mathematics—
Galois fields,
polynomials,
a French teenager
who died in a duel
and left us
the algebra of redundancy.
The message carries more than itself.
The extra bits aren't waste—
they're the difference between
"I can read this"
and "I can read this even if
seven percent of it
has been torn away."
Évariste Galois
was twenty years old.
He knew he would die
and he spent his last night
writing down mathematics
instead of love letters.
Maybe he understood
that the letters would not survive
but the theorems would—
the error correction
outlasting the man
who needed it most.
