HARDY
1729
The Hardy-Ramanujan number, also known as the smallest "taxicab number," is 1729. It is famous for being the smallest number expressible as the sum of two cubes in two different ways: (1729 = 1^3 + 12^3) and (1729 = 9^3 + 10^3). The number gained notoriety from a story involving mathematicians G.H. Hardy and Srinivasa Ramanujan, highlighting its significance in number theory.
Srinivasa Ramanujan was a pioneering Indian mathematician known for his groundbreaking contributions to number theory, continued fractions, and infinite series. He independently developed theorems, such as the Ramanujan Prime and the Ramanujan-Hardy number (1729), and introduced the concept of mock theta functions. His work laid the foundation for many areas of mathematics, influencing fields like partition theory and q-series. Despite limited formal training, Ramanujan's insights have had a lasting impact, inspiring mathematicians worldwide.

Srinivasa Ramanujan made significant contributions to various areas of mathematics, including number theory, continued fractions, and infinite series. His work on partition functions and modular forms has had a lasting impact, influencing both pure and applied mathematics. Ramanujan’s intuitive approach and theorems, such as the famous Ramanujan-Hardy number 1729, exemplify his unique insights and creativity in mathematical thought. His collaboration with mathematician G.H. Hardy also helped bridge Eastern and Western mathematical traditions.
C.H.Hardy was a British mathematician. Srinivasa Ramanujan was an Indian mathematician. Hardy visited Ramanujan in hospital. In Hardy's words "I remember once going to see him when he was ill at Putney. I had ridden in taxi cab number 1729 and remarked that the number seemed to me rather a dull one, and that I hoped it was not an unfavorable omen. "No," he replied, "it is a very interesting number; it is the smallest number expressible as the sum of two cubes in two different ways." Hence the Hardy-Ramanjuran number which is 1729.
The first Indian to earn a PhD in mathematics was Srinivasa Ramanujan. Ramanujan was a self-taught mathematician who made significant contributions to number theory, infinite series, and continued fractions. He obtained his PhD from the University of Cambridge in 1916 under the guidance of the renowned mathematician G.H. Hardy. Ramanujan's work continues to influence mathematics to this day.
As the speciality of this number i.e., smallest number that can be shown as sum of two positive cubes in two ways was found by Ramanujam in the presence of Hardy.so it is also called hardy-ramanujan number.
Srinivasa Ramanujan, who was said by GH Hardy to have talent "in the same league as legendary mathematicians such as Gauss, Euler, Cauchy, Newton and Archimedes", passed away at the age of 32 in Chetput, Madras, India.
