The Mystery of Palindromes: From Ancient Sator Squares to Genetic DNA Sequences
From ancient Roman stone engravings and poetic wordplay to CRISPR-Cas9 DNA restriction enzymes, discover the surprising universality of palindromic symmetry.
Symmetry in Language and Nature
A palindrome is any sequence of characters, words, or symbols that reads identically in both directions. Standard literary conventions disregard punctuation, spacing, and capitalization.
Famous Examples
