On primes, sum of numbers, Mandelbrot fractal and theory of relativity

The book deals with the linear position of prime numbers, with the simultaneous chaotic nature of their distribution. It also derives some recursive formulas of prime numbers of nested square roots and shows their connection with the Pi. It also presents a new approach to the problem of the negative sum of natural numbers. The conclusion presents considerations on the special theory of relativity without the use of time and velocity.
