The Music of the Primes: Why an Unsolved Problem in Mathematics Matters

Product Information

Riemann had found one very special imaginary landscape, generated by something called the zeta function, which he discovered held the secret to prime numbers. In particular, the points at sea-level in the landscape could be used to produce these special harmonic waves which changed Gauss's graph into the genuine staircase of the primes. Riemann used the coordinates of each point at But where on earth had Riemann found these strange prime number harmonics which corrected Gauss's guess into the true sound of the primes? Well, he was actually messing about with an exciting new subject that was emerging out of the French Revolution: the new world of imaginary numbers. For years people could not accept that a negative number might have a square root - after all, a So how fair are the prime number dice? Mathematicians call a dice "fair" if the difference between the theoretical behaviour of the dice and the actual behaviour after N tosses is within the region of the square root of N. The heights of Riemann's harmonics are given by the east-west coordinate of the corresponding point at sea-level. If the east-west coordinate is c then How can one compute the harmonics shown in the first picture in the section titled "Riemann's Harmonics"? Some Mathematica code would be highly preferred.

working in Göttingen, discovered that music could explain how to change Gauss's graph into the staircase graph that really counted the primes. Shapes and sounds Di certo questo è il più bel libro sulla matematica che abbia mai letto, racconta l’appassionante storia della matematica, fatta di scoperte e progressi che viaggiano da un capo all’altro del mondo, ma soprattutto la storia di matematici, grandi uomini che competono per arrivare oltre i confini della conoscenza e personaggi spesso affascinanti: Euclide, Gauss, Riemann, Ramanujan, Weil… quanto vorrei poter parlare per un momento con loro! Nearly 150 years ago, a German mathematician named Bernard Riemann came as close as anyone has ever come to solving this problem. In 1859 he presented a paper on the subject of prime numbers to the Berlin Academy. At the heart of his presentation was an idea -- a hypothesis -- that seemed to reveal a magical harmony between primes and other numbers. It was an idea that Riemann argued was very likely to be true. But after his death, his housekeeper burned all of his personal papers, and to this day, no one knows whether he ever found the proof. Prime numbers are unique; they can only be divided by themselves and the number one. They crop up irregularly as you count upwards and are seemingly wholly unpredictable in their occurrence. There is an infinite number of them and they appear to be as important in life, the universe and everything as the numbers in the Fibonacci series.Desde Euclides, que demostró que los números primos son infinitos (hoy el más elevado es 2 elevado a 13.466.917 - 1, hallado en 2001 por un estudiante canadiense, un número de cuatro millones de cifras), hasta Euler en San Petersburgo, el trío de Gotinga (Gauss, Riemann, Dirichlet), Cauchy, las series armónicas de Pitágoras, Fourier, Hilbert, Hardy, Skewes, Ramanujan (el matemático Indio de Cambridge, que fue protagonista de una película reciente), Gödel y su teorema de la incompletitud, las máquinas de Touring, la criptografía RSA y la relación entre los primos y la física cuántica. Un recorrido inacabado y muy bien contado. In this breathtaking book, mathematician Marcus du Sautoy tells the story of the eccentric and brilliant men who have struggled to solve one of the biggest mysteries in science. It is a story of strange journeys, last-minute escapes from death and the unquenchable thirst for knowledge. Above all, it is a moving and awe-inspiring evocation of the mathematician's world and the beauties and mysteries it contains.

There are fewer in any interval greater than let’s say 1000, than the same interval less than 1000. This is intuitively obvious since the greater the number the more lesser numbers there that might be divided into it evenly. Interestingly, there is always at least one prime between any number and its double. About 160 years ago, Bernhard Riemann came up with a hypothesis about the distribution of prime numbers, which is still unproven to this day. In The Music of the Primes, Marcus du Sautoy takes you through history as various mathematical powerhouses all tried to solve this famous problem. There is a good reason for the religious, even spiritual, interpretation of mathematics - particularly number theory, and especially prime numbers. In the first instance, unlike any other area of human inquiry - even theology - the results obtained in mathematics never change. Euclid’s proofs may be superseded by more general analysis but they are nevertheless entirely correct and need no modification in a world of radically different cosmology and technology. Gauss's guess was based on throwing a dice with one side marked "prime" and the others all blank. The number of sides on the dice increases as we test larger numbers and Gauss discovered that the logarithm function could tell him the number of sides needed. For example, to test primes around 1,000 requires a six-sided dice. To make his guess at the number of primes, Gauss assumed that a

negative times a negative is always positive. But the French revolution gave mathematicians the courage to think of new ideas. They invented new months and new days of the week, so why not new numbers? So came about the birth of the new number i, the square root of minus one. All the other imaginary numbers were got by taking combinations of this new number with the ordinary numbers, for running East-West in this map of imaginary numbers, while the North-South direction corresponded to the imaginary part. So each imaginary number, like -3+4 i, just became a point in this map: go 3 units west and 4 units north. Suddenly a two-dimensional map of the world of imaginary numbers emerged, making these numbers far more tangible.

Again by adding the heights of all these sine waves together we can see the square shape of the clarinet emerging from the basic sine wave corresponding to the A of the tuning fork. Follow this link to see the way the first five harmonics combine to build up the wave shape created by a clarinet.
