Explore A00012, Nero — the Hemingway sequence: the count of 1s in binary representations. We trace its links to Pascal's triangle and the parity of binomial coefficients, its recursive fractal generation, and its surprising connections to Gould's sequence. We also discuss how this simple binary weight appears in Diophantine equations, error-correcting codes, and mystery calculator sequences, including the odd-number subset A06387. A compact, math-filled tour of why binary matters in number theory.
