Quasicrystal
A quasiperiodic crystal, or, in short, quasicrystal, is a structure that is ordered but not periodic. A quasicrystalline pattern can continuously fill all available space, but it lacks translational symmetry...

Explanation

A Fibonacci sequence is the result of a recursive iteration, which repeats a structural pattern with a small difference. This aspect of deflationary construction by difference and repetition is also implicit in a quasicrystal. In fact, if we use only two symbols for the starting points of the sequence ( instead of adding numbers ) and form a chain with the same rule, the relation becomes visible.

By definition, the first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two.

In mathematical terms, the sequence Fn of Fibonacci numbers is defined by the recurrence relation
Recurrence relation
In mathematics, a recurrence relation is an equation that recursively defines a sequence, once one or more initial terms are given: each further term of the sequence is defined as a function of the preceding terms....
