  2. Fibonacci word - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_word

    Suppressing the last two letters of a Fibonacci word, or prefixing the complement of the last two letters, creates a palindrome. Example: 01S 4 = 0101001010 is a palindrome. The palindromic density of the infinite Fibonacci word is thus 1/φ, where φ is the golden ratio: this is the largest possible value for aperiodic words. [3] In the ...

    en.wikipedia.org/wiki/Lettering

    Lettering is an act or result of artfully drawing letters, instead of writing them simply. Lettering is considered an art form, where each letter in a phrase or quote acts as an illustration . Each letter is created with attention to detail and has a unique role within a composition . [ 1 ]

  4. Phyllotaxis - Wikipedia

    en.wikipedia.org/wiki/Phyllotaxis

    The numerator and denominator normally consist of a Fibonacci number and its second successor. The number of leaves is sometimes called rank, in the case of simple Fibonacci ratios, because the leaves line up in vertical rows. With larger Fibonacci pairs, the pattern becomes complex and non-repeating. This tends to occur with a basal configuration.

    Fibonacci was born around 1170 to Guglielmo, an Italian merchant and customs official. [3] Guglielmo directed a trading post in Bugia (Béjaïa), in modern-day Algeria. [16] Fibonacci travelled with him as a young boy, and it was in Bugia (Algeria) where he was educated that he learned about the Hindu–Arabic numeral system. [17] [7]

    Examples are the Chimney of Turku Energia, in Turku, Finland, featuring the start of the Fibonacci sequence in 2 m high neon lights, and the representation of the first Fibonacci numbers with red neon lights on one face of the four-faced dome of the Mole Antonelliana in Turin, Italy, part of the artistic work Il volo dei Numeri ("Flight of the ...

    Fibonacci instead would write the same fraction to the left, i.e., . Fibonacci used a composite fraction notation in which a sequence of numerators and denominators shared the same fraction bar; each such term represented an additional fraction of the given numerator divided by the product of all the denominators below and to the right of it.

  9. Fibonacci sequence - Wikipedia

    en.wikipedia.org/wiki/Fibonacci_sequence

    A Fibonacci prime is a Fibonacci number that is prime. The first few are: [47] 2, 3, 5, 13, 89, 233, 1597, 28657, 514229, ... Fibonacci primes with thousands of digits have been found, but it is not known whether there are infinitely many. [48] F kn is divisible by F n, so, apart from F 4 = 3, any Fibonacci prime must have a prime index.
