Ramanujan was an Indian mathematician. Extremely poor, he was largely self-taught from age 15. In 1913, he began a correspondence with English mathematician Godfrey H. Hardy that took him to England, where he made advances, especially in the theory of numbers, the partition of numbers, and the theory of continued fractions. He died of tuberculosis at age 32, generally unknown but recognized by mathematicians as a phenomenal genius. What anecdote exists about Ramanujan and the number 1,729? Discuss
