It's the smallest number expressible as the sum of two cubes in two different ways." Because of this incident, 1729 is now known as the Ramanujan-Hardy

Hardy

Godfrey Harold Hardy FRS (7 February 1877 – 1 December 1947) was an English mathematician, known for his achievements in number theory and mathematical analysis. In biology, he is known for the Hardy–Weinberg principle, a basic principle of population genetics.

Why 1729 is a magic number?

Discovered by mathemagician Srinivas Ramanujan, 1729 is said to be the magic number because it is the sole number which can be expressed as the sum of the cubes of two different sets of numbers. Ramanujan’s conclusions are summed up as under: 1) 10 3 + 9 3 = 1729 and 2) 12 3 + 1 3 = 1729.

What is another Ramanujan number?

Some of these numbers include : {2, 9, 16, 28, 35, 54, 65, 72, 91, 126, 128, 133, 152, 189, 217, 224, 243, 250, 280, 341, 344, 351, 370, 407, 432, 468, 513, 520, 539, 559, 576, 637, 686, 728, 730, 737, ...}

Why is 1729 called Ramanujan?

It's the smallest number expressible as the sum of two cubes in two different ways." Because of this incident, 1729 is now known as the Ramanujan-Hardy number.

Hardy Ramanujan Number | Discovery of this number - 1729

Is 1729 a perfect cube?

Is 1729 a Perfect Cube? The number 1729 on prime factorization gives 7 × 13 × 19. Here, the prime factor 7 is not in the power of 3. Therefore the cube root of 1729 is irrational, hence 1729 is not a perfect cube.

What is 1 2 3 n Ramanujan?

For those of you who are unfamiliar with this series, which has come to be known as the Ramanujan Summation after a famous Indian mathematician named Srinivasa Ramanujan, it states that if you add all the natural numbers, that is 1, 2, 3, 4, and so on, all the way to infinity, you will find that it is equal to -1/12.

Is 4104 is Hardy Ramanujan number?

Numbers like 1729, 4104, 13832, are known as Hardy – Ramanujan Numbers. They can be expressed as sum of two cubes in two different ways.

Is 2520 discovered by Ramanujan?

Discovered by the great sage Srinivasa Ramanujan, let's observe the number 2520. Ramanujan outnumbered mathematics, contributed immensely to the number theory, infinity series, continued fractions, and much more.

Is 1729 special?

Ramanujan explained that 1729 is the only number that is the sum of cubes of two different pairs of numbers: 12³ + 1³, and 10³ + 9³. It was not a sudden calculation for Ramanujan.

Why was Ramanujan so genius?

Among his achievements in mathematics, Ramanujan built a bridge between number theory and analysis, another field in mathematics, which was extraordinary because the former mostly focuses on whole numbers and the latter on continuously-changing quantities.

What is Ramanujan formula?

In mathematics, in the field of number theory, the Ramanujan–Nagell equation is an equation between a square number and a number that is seven less than a power of two. It is an example of an exponential Diophantine equation, an equation to be solved in integers where one of the variables appears as an exponent.

Did Ramanujan know infinity?

Ramanujan's contribution extends to mathematical fields such as complex analysis, number theory, infinite series, and continued fractions. Infinite series for pi: In 1914, Ramanujan found a formula for infinite series for pi, which forms the basis of many algorithms used today.

Did Ramanujan exist?

Ramanujan (1887–1920) was born and died, aged just 32, in Southern India. But in one of the most extraordinary events in mathematical history, he spent the period of World War I in Trinity College Cambridge at the invitation of the leading British mathematician Godfrey Harold (G. H.)

What is the biggest Hardy-Ramanujan number?

"1729: Taxi Cab Number or Hardy-Ramanujan Number".

Why is 28 the perfect number?

A number is perfect if all of its factors, including 1 but excluding itself, perfectly add up to the number you began with. 6, for example, is perfect, because its factors — 3, 2, and 1 — all sum up to 6. 28 is perfect too: 14, 7, 4, 2, and 1 add up to 28. But perfect numbers aren't common at all.

Which is the smallest Ramanujan numbers?

So, as per the definition of Hardy Ramanujan's number, we get that number. 1729 is the smallest integer which can be represented in the form of two cubes in two ways.

Why is 13832 called Ramanujan number?

Where a, b , c and d are 4 different positive numbers. This combination is very rare. If we try one by one option given, then for 13832, we can find two such pairs of numbers. It is clear that 13832 is the given Hardy Ramanujan number.

Is the Ramanujan summation true?

So the sum of all numbers is minus one twelfth AND is unity (1) and is infinity. The way 100 cents is one dollar and 60 seconds is 1 minute and is 60/3600 hour and is 0.01666 hour. Ramanujan's summation is presently being used to understand String Theory, showing it is true and very real.

What is the unsolved formula of Ramanujan?

Ramanujan identified a way to generate an infinite number of near misses of the form: x3 + y3 = z3 ± 1. 103 + 93 = 123 + 13; 63 + 83 = 93 − 1; 1353 + 1383 = 1723 − 1; 7913 + 8123 = 10103 − 1; 111613 + 114683 = 142583 + 1.

What is the last theory of Ramanujan?

In mathematics, the Hardy–Ramanujan theorem, proved by G. H. Hardy and Srinivasa Ramanujan (1917), states that the normal order of the number ω(n) of distinct prime factors of a number n is log(log(n)). Roughly speaking, this means that most numbers have about this number of distinct prime factors.

What is Ramanujan's magic square?

Ramanujan magic square is a special kind of magic square that was invented by the Indian mathematician Srinivasa Ramanujan. It is a 3×3 grid in which each of the nine cells contains a number from 1 to 9, and each row, column, and diagonal have the same sum.

Is 1729 even or odd?

Since the remainder obtained on dividing 1729 by 2 is 1, 1729 is an odd number.

Who invented infinity?

Infinity is a mathematical concept originating from Zeno of Elia (~450 BC) who tried to show its “physical” impossibility. This resulted in the “arrow paradox”, but which was solved later on. Many mathematicians and physicists went on to try understanding infinity and to explain it by various theories and experiments.

What is the IQ of Ramanujan?

Srinivasa Ramanujan: IQ 185

Born in India in 1887, Srinivasa Ramanujan is one of the most influential mathematicians in the world. He made significant contributions to the analytical theory of numbers, as well as elliptic functions, continued fractions, and infinite series. He had an estimated IQ of 185.
