In 1904 the biologist Ernst Haeckel published plates so precise and so beautiful that scientists argued whether they were data or decoration. His radiolarians - microscopic sea creatures - look like lanterns, like cathedrals, like the inside of a snowflake.
He was accused of making nature too symmetrical. Perhaps. But he was drawing the truth of the very small, and the very small really is this ordered. Color it and you are coloring the architecture of a single cell.
