The anecdote is a part of Ramanujan's biography The number 1729 is known as the Ramunujan Number. It was Ramanujan who discovered that it is the smallest number that can be expressed as the sum of two cubes in two different ways. 1729 = 13 + 123 = 93 + 103. — Orpita Majumdar, via e-mail Ramanujan and the Number π However, this event did not stop him from continuing his training, which from 1906 became strictly self-taught.

2021-02-19 Ramanujan is said to have made this observation to Hardy who happened to be visiting him while he was recovering in a sanatorium in England, in the year 1918; on entering Ramanujan’s room, Hardy apparently said (perhaps just to start a conversation), “I came in a taxi whose number was 1729. As physicists add two more dimensions to this ‘miraculous’ number 24, the counting the total number of vibrations appearing in relativistic theory yields a 26-dimensional space-time. When, on the The graph above shows the distribution of the first 100 Ramanujan numbers (2-way pairs) in the number field. The 100th of these Ramanujan doubles occurs at: 64^3 + 164^3 = 25^3 + 167^3 = 4,673,088. Of these first 100 Ramanujan numbers, 49 are primitive as they are not multiples of smaller solutions. 2020-12-10 Ramanujan proved a generalization of Bertrand's postulate, as follows: Let \pi (x) π(x) be the number of positive prime numbers \le x ≤ x; then for every positive integer n n, there exists a prime number Add details and clarify the problem by editing this post .

1729 is the sum of the cubes The number 1729 is known as the Hardy–Ramanujan number after a famous visit by Hardy to see Ramanujan at a 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." As of recently, apart from the mention of the number 1729 in the anecdote above, no further information was known about Ramanujan’s knowledge of the number.

Interesting question nevertheless – nico Jul 10 '12 at 10:01 2016-05-12 · Ramanujan concluded that, for each set of coefficients, the following relations hold: We see that the values , and in the first row correspond to Ramanujan’s number 1729. The expression of 1729 as two different sums of cubes is shown, in Ramanujan’s own handwriting, at the bottom of the document reproduced above. This incident launched the ‘Hardy-Ramanujan number’ or ‘taxicab number’ into the world of math. Taxicab numbers are the smallest integers which are the sum of cubes in n different ways. The first taxicab number is simple 2 = 1^3+1^3. The second is 1729, which can be written as the sum of two cubes in two different ways. As you unlock each tile, a number reveals itself and at the end of nine tiles, the numbers draw the player into an area of number theory that fascinated Ramanujan.
