The same number can also be expressed as 1000 + 729, which is also 10 3 + 9 3 . This number is now called the Hardy-Ramanujan number, and also the smallest numbers that may be expressed because the sum of two cubes in n other ways are dubbed taxicab numbers. 1729 was called as Ramanujan Hardy number after an interesting incident that took place between Ramanujan and his mentor, Hardy. In fact, if you remove the return after System.out.println () and just let it run, you'll see that it prints 110808 = 6^3 + 48^3 = 27^3 + 45^3 before 110656 = 4^3 + 48^3 = 36^3 + 40^3.

The number 1729 is known as the Ramanujan number or Hardy-Ramanujan number. fSrinivasa Ramanujan, with almost no formal training in pure mathematics, made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Then, Ramanujan replied, the number 1729 is the smallest number expressible as the sum of two cubes in two distinct ways. The number plate of the car was 1729.

In December 1903, at the age of 16, Ramanujan passed the matriculation exam for the University of Madras. If you mention the number “1729” or the phrase “Taxicab Problem” to any mathematician, it will immediately bring up the subject of the self-taught Indian mathematical genius Srinivasa Ramanujan. It is 1729 which is the smallest number that can be expressed as the sum of two sets of cubes each. That is 1729 = (1)^3 + (12)^3 = (9)^3 + (10)^3... Though he didn't had formal education in pure mathematics, he gave nearly 3500 results in theorems and mathematical identities. The story goes like this: Hardy and Ramanujan were travelling in a cab . Srinivasa Ramanujan. Given a positive integer L, the task is to find all the Ramanujan Numbers that can be generated by any set of quadruples (a, b, c, d), where 0 < a, b, c, d ≤ L. Ramanujan Numbers are the numbers that can be expressed as sum of two cubes in two different ways. Ramanujan, the Man who Saw the Number Pi in Dreams. 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.

Question: Write java program to find if a number is the sum of two cubes in two different ways. Srinivasa Ramanujan was the renowned Indian Mathematician. One of the projects they completed was a formula to approximate the number of partitions for any number \(n\), to which an algebraic solution had seemed intractable. I'm a fair way from understanding everything you've written, but I have already learnt some useful things. Here is a well known property that Ramanujan noted about the number 1729: he said to Hardy one day: It is the smallest positive integer that can be written as the sum of two positive cubes in more than one way. “I remember once going to see him when he was ill at Putney. It is the smallest natural number that can be expressed as the sum of two cubes, in two different ways, i.e., 1729 = 1 3 + 12 3 = 9 3 + 10 3. ‘Cubes’ are numbers like 1, 8, 27, 64, 125, 216,…. Attention reader! Attention reader! A HARDY-RAMANUJAN TYPE INEQUALITY FOR SHIFTED PRIMES AND SIFTED SETS 3 1.4. ” 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.” (This is, of course correct. series which, amongst other results, extended the result of Hagis cited above from a prime q to an Hardy-Ramanujan Theorem. Hardy Ramanujam theorem states that the number of prime factors of n will approximately be log(log(n)) for most natural numbers n. Examples : 5192 has 2 distinct prime factors and log(log(5192)) = 2.1615. GitHub. [G. H. Hardy as told in "1729 (number)"] This story is very famous among mathematicians.
