He sees numbers in the squares of light pricking his thatched roof and in the beasts dancing on the temple tower. He writes mathematics with his finger in the sand, across the pages of his notebooks, and with chalk on the temple floor. "What is small?" he wonders. "What is big?" Head in the clouds, Ramanujan struggles in school -- but his mother knows that her son and his ideas have a purpose. As he grows up, Ramanujan reinvents much of modern mathematics, but where in the world could he find someone to understand what he has conceived?Author Amy Alznauer gently introduces young readers to math concepts while Daniel Miyares's illustrations bring the wonder of Ramanujan's world to life in the inspiring real-life story of a boy who changed mathematics and science forever. Back matter includes a bibliography and an author's note recounting more of Ramanujan's life and accomplishments, as well as the author's father's remarkable discovery of Ramanujan's Lost Notebook.
