Nature Through Matematics

        In Mathematics there are an infinity of strings of numbers, which are based on a formula, based on which the elements of the string are generated. For example the sequence of prime numbers: '2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67,… 97, 101 , 103,… 2n + 1,… 2n + 1 ”consists of numbers that are divided exactly by 1 and by themselves. Or the sequence of numbers seems natural: "2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22… n" whose elements are divided exactly into two (n = 2p). Or the sequence of numbers consisting of the powers of 3: "3, 9, 27, 81, 243, 729, 2187" which can also be written "31, 32, 33, 34, 35, 36, 37, 38, 39 ... ".

    Pine / fir cones Fibonacci similarly, the seeds on a cone are arranged in a spiral pattern. Each cone consists of a pair of spirals, each twisting upwards and in opposite directions. The number of steps will almost always match a pair of consecutive Fibonacci numbers. For example, a 3-5 cone is one on which the spirals will meet backwa
rds after three steps on the left spiral and 5 steps on the right.

Not surprisingly, spiral galaxies also follow the familiar Fibonacci pattern. The Milky Way has several spiral arms, each of which is a logarithmic spiral of about 12 degrees. As an interesting side note, spiral galaxies seem to defy the laws of Newtonian physics. As early as 1925, astronomers realized that because the angular velocity of rotation of the galactic disk varies with distance from the center, the radial arms should become curved as the galaxy rotates. Later, after a few rotations, the spiral arms should wrap around a galaxy. But they don't - hence the so-called winding problem. The outer stars, it seems, move at a faster speed than expected - a unique feature of the cosmos that allows it to retain its shape.
