## Fibonacci Numbers Essay

Its a good essay, for a Math project. Well don, although you could have had more specific examples.

The Fibonacci numbers were first discovered by a man named Leonardo

Pisano. He was known by his nickname, Fibonacci. The Fibonacci sequence is a

sequence in which each term is the sum of the 2 numbers preceding it. The first 10

Fibonacci numbers are: (1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89). These numbers are

obviously recursive.

Fibonacci was born around 1170 in Italy, and he died around 1240 in Italy.

He played an important role in reviving ancient mathematics and made significant

contributions of his own. Even though he was born in Italy he was educated in

North Africa where his father held a diplomatic post. He did a lot of traveling with

his father. He published a book called Liber abaci, in 1202, after his return to Italy.

This book was the first time the Fibonacci numbers had been discussed. It was

based on bits of Arithmetic and Algebra that Fibonacci had accumulated during his

travels with his father. Liber abaci introduced the Hindu-Arabic place-valued

decimal system and the use of Arabic numerals into Europe. This book, though,

was somewhat contraversial because it contradicted and even proved some of the

foremost Roman and Grecian Mathematicians of the time to be false. He published

many famous mathematical books. Some of them were Practica geometriae in

1220 and Liber quadratorum in 1225.

The Fibonacci sequence is also used in the Pascal trianle.

The sum of each diagnal row is a

fibonacci number. They are also in the right sequence: 1,1,2,5,8.........

Fibonacci sequence has been a big factor in many patterns of things in nature.

One has found that the fractions u/v representing the screw-like arrangement of

leaves quite often are members of the fibonacci sequence. On many plants, the

number of petals is a...

### The Golden Ratio Essay

1026 words - 4 pages The Golden Ratio Certain pictures, objects, and animals appeal to the human mind more than others. Proportions and images of symmetry often contribute to our fascination with them. Often, when examined carefully, you may find a common “coincidence” between man made objects and those found naturally in nature. This fluke, however, may be used to ascertain various mathematical relationships between these objects. This paper will introduce...### Fractals: Stonehenge, the Pyramids of Giza, the Parthenon

2299 words - 9 pages My infatuation in fractals began freshmen year at Greeley after taking a Seminar with one of the seniors. I’m not sure exactly when simple interest turned to a kind of obsession, but during that lesson something seemed to click. It seemed as if this was the universe’s answer to everything; the mystery was solved, however complex the answer was to understand. I’m still not sure if I was misunderstanding the lesson, or if I had somehow seen it for...### Linear Feedback Shift Registers

2764 words - 11 pages Abstract: Linear Feedback Shift Registers (LFSRs) are considered powerful methods for generating pseudo-random bits in cryptography algorithm applications. In this paper it is shown that the linear dependencies in the generated random bit sequences can be controlled by adding a chaotic logistic map to the LFSR’s systems. The structure of the LFSR’s output sequence in combination with a chaotic map is analyzed and proved to have at least as much...### Assignment regarding the fibonacci sequence and the golden ratio - maths assignemnt

1881 words - 8 pages The Golden Ratio The Golden Rectangle and Ratio The Golden Rectangle and Golden Ratio have always existed in the physical universe. Nobody knows exactly when it was first discovered and applied to mankind. Many mathematicians assume that the Golden Rectangle has been discovered and rediscovered multiple times throughout history. This would explain why it is called many different names such as the Golden Mean, divine proportion, or the...### The Theory of Evolution is Wrong

2119 words - 8 pages “Often a cold shudder has run through me, and I have asked myself whether I may have not devoted myself to a phantasy.” -- Charles Darwin I’m sure everyone in this room has heard that science proves evolution, and that people who believe that God created everything in six days about six thousand years ago have succumbed to a myth. However, when you take the real data and study it using scientific methods, you make a significant discovery -...### The Golden Ratio

1016 words - 4 pages The golden ratio is approximately 1.6. The mysteriously aesthetically pleasing ratio is the relation "a+b is to a as a is to b" or a+b/b=a/b=φ. It is denoted as the Greek letter φ or Φ (lower case, upper case respectively, upper case most often used as reciprocal). The letter is pronounced "phi". The golden ratio is found prominently in art, nature, and...### music and math

1284 words - 5 pages The title asks one to what extent is truth different among mathematics, the arts and ethics; it does not question the existence of truth. I interpret truth as justified belief and categorize it into three approaches: personal, social and universal. Personal is what one perceives to be true, social is what a group perceives to be true, and universal is what the whole perceives to be true (Bernardin). In this essay, it will be shown that the...### Cameras and Photography

Photography Is used for business, science, manufacturing, art, recreational purposes, mass communication, and more. Photography is using light to do amazing things, and some people think of photography as a story that just needs to be told. Ansel Adams probably believed this. He said, “You don’t take a...### Functional Data Structures in Common Lisp:

Advantages of functional programs include...The relationship between mathematics and science has long been studied by philosophers, mathematicians, scientists, and historians. Since ancient times, people have sought to understand the world around them and looked for mathematical explanations for natural phenomena. Some say that mathematics is the language of science; indeed, it has enabled humankind to make remarkable advances in science and technology. For example, people have put satellites in orbit and sent space probes to study other planets by understanding the mathematics that describes gravity and the motion of objects. However, the question remains: Did humans invent mathematics to help describe nature, or are we just discovering something that is intrinsic to nature itself?

One fascinating mathematical pattern that shows up in unexpected places is the Fibonacci sequence. Each subsequent number in the Fibonacci sequence is the sum of the previous two numbers. The sequence begins with 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, and continues infinitely. The Fibonacci sequence is named after an Italian mathematician who introduced it to Western mathematics in 1202; it had, however, been known in India before that time. The numbers of the Fibonacci sequence have connections to various aspects of mathematics as well as applications in economics and computer science. In addition, Fibonacci numbers are commonly found in biological systems. For example, the family tree of a male honeybee—a drone—follows the Fibonacci sequence. Female bees have two parents, but drones hatch from unfertilized eggs. The numbers of each generation follow the Fibonacci sequence: each drone has one parent, two grandparents, three great-grandparents, five great-great-grandparents, and so on. Fibonacci numbers are also expressed in the way some plants grow. They appear in the arrangement of leaves on stems, the branching of trees, the number of petals on a flower, and the spiral patterns of seed heads and pinecones.

Pi (or π) is another example of a compelling connection between mathematics and the physical world. Pi is a mathematical constant commonly defined as the ratio of a circle's circumference to its diameter. It is often approximated as 3.14159, although computers have been used to calculate it to the trillions digits. Pi is an irrational number that cannot be expressed as a fraction and has an infinite number of digits in its decimal representation. The Greek letter symbol was widely adopted in the 18th century; however, humans have known about the approximate value of pi for thousands of years. Although pi is related to the geometry of circles, it also appears in many other areas of mathematics and science, including trigonometry, statistics, fractals, cosmology, classical mechanics, quantum mechanics, electromagnetism, and thermodynamics.
