Pick up a pinecone and count the spiral rows of scales. You may find eight spirals winding up to the left and 13 spirals winding up to the right, or 13 left and 21 right spirals, or other pairs of numbers. The striking fact is that these pairs of numbers are adjacent numbers in the famous Fibonacci series: 1, 1, 2, 3, 5, 8, 13, 21... Here, each term is the sum of the previous two terms. The phenomenon is well known and called phyllotaxis. Many are the efforts of biologists to understand why pinecones, sunflowers, and many other plants exhibit this remarkable pattern. Organisms do the strangest things, but all these odd things need not reflect selection or historical accident. Some of the best efforts to understand phyllotaxis appeal to a form of self-organization. Paul Green, at Stanford, has argued persuasively that the Fibonacci series is just what one would expects as the simplest self-repeating pattern that can be generated by the particular growth processes in the growing tips of the tissues that form sunflowers, pinecones, and so forth. Like a snowflake and its sixfold symmetry, the pinecone and its phyllotaxis may be part of order for free

Highly complex numbers like the Comma of Pythagoras, Pi and Phi (sometimes called the Golden Proportion), are known as irrational numbers. They lie deep in the structure of the physical universe, and were seen by the Egyptians as the principles controlling creation, the principles by which matter is precipitated from the cosmic mind.
Today scientists recognize the Comma of Pythagoras, Pi and the Golden Proportion as well as the closely related Fibonacci sequence are universal constants that describe complex patterns in astronomy, music and physics. ...
To the Egyptians these numbers were also the secret harmonies of the cosmos and they incorporated them as rhythms and proportions in the construction of their pyramids and temples.

The earliest known work in Arabic arithmetic was written by al-Khowârizmî, a mathematician who lived around 825, some four hundred years before Fibonacci.11 Although few beneficiaries of his work are likely to have heard of him, most of us know of him indirectly. Try saying “al-Khowârizmî” fast. That’s where we get the word “algorithm,” which means rules for computing.12 It was al-Khowârizmî who was the first mathematician to establish rules for adding, subtracting, multiplying, and dividing with the new Hindu numerals. In another treatise, Hisâb al-jabr w’ almuqâbalah, or “Science of transposition and cancellation,” he specifies the process for manipulating algebraic equations. The word al-jabr thus gives us our word algebra, the science of equations.13

It is the first two numbers of the Fibonacci sequence. It is the empty product. Any number raised to the zero power is one. It might be argued that one is the most independent number known to man. It can do things no other number is capable of.

When he was about fourteen years of age, Leonardo would have left the fondaco and most likely traveled with an older merchant, a form of apprenticeship system common in those days. Around that time his father summoned him to Bugia. No one knows exactly when he made this voyage. In the introduction to Liber abbaci, he later wrote: “When my father, who had been appointed by his country as public notary in the customs at Bugia acting for the Pisan merchants going there, was in charge, he summoned me to him while I was still a child, and having an eye to usefulness and future convenience, desired me to stay there and receive instruction in the school of accounting.

Underlying all this activity—in the customhouses, on the wharves, in every place of business—were numbers. Merchants measured out their wares and negotiated prices; customs officers calculated taxes to be levied on imports; scribes and stewards prepared ships’ manifests, recording the values in long columns using Roman numerals. They would have put their writing implements to one side and used either their fingers or a physical abacus to perform the additions, then picked up pen and parchment once again to enter the subtotals from each page on a final page at the end. With no record of the computation itself, if anyone questioned the answer, the entire process would have to be repeated.

There was no escaping math, after all. It was everywhere, especially in nature. You could go as far to say that math was nature. Pi describe the arc of a rainbow, the way ripples spread in a body of water, the dimensions of the moon and sun. Fractals could be observed in halved sections of red cabbage, the topography of deserts, the branching of lightning bolts. And take the old man glaring out from his shirt, Leonardo Fibonacci, who discovered that a basic number sequence predicted the arrangement of scales on a pinecone, the distribution of petals on flowers, the spiral of a snail shell, the furcation of veins in the human body, even the structure of DNA. When all the people were gone, the numbers would persist.

The conclusion that the Egyptians of the Old Kingdom were acquainted with both the Fibonacci series and the Golden Section, says Stecchini, is so startling in relation to current assumptions about the level of Egyptian mathematics that it could hardly have been accepted on the basis of Herodotus' statement alone, or on the fact that the phi [golden] proportion happens to be incorporated in the Great Pyramid.
But the many measurements made by Professor Jean Philippe Lauer, says Stecchini, definitely prove the occurrence of the Golden Section throughout the architecture of the Old Kingdom.... Schwaller de Lubicz also found graphic evidence that the pharonic Egyptians had worked out a direct relation between pi and phi in that pi = phi^2 x 6/5.

The number system we use today—the Hindu-Arabic system—was developed in India and seems to have been completed by around 700 CE. Indian mathematicians made advances in what would today be described as arithmetic, algebra, and geometry, much of their work being motivated by an interest in astronomy. The system is based on three key ideas: notations for the numerals, place value, and zero.

The choice of ten basic number symbols—that is, the Hindus’ choice of the base 10 for counting and doing arithmetic—is presumably a direct consequence of using fingers to count. When we reach ten on our fingers we have to find some way of starting again, while retaining the calculation already made. The role played by finger counting in the development of early number systems would explain why we use the word “digit” for the basic numerals, deriving from the Latin word digitus for finger.

To claim that mathematics is purely a human invention and is successful in explaining nature only because of evolution and natural selection ignores some important facts in the nature of mathematics and in the history of theoretical models of the universe. First, while the mathematical rules (e.g., the axioms of geometry or of set theory) are indeed creations of the human mind, once those rules are specified, we lose our freedom. The definition of the Golden Ratio emerged originally from the axioms of Euclidean geometry; the definition of the Fibonacci sequence from the axioms of the theory of numbers. Yet the fact that the ratio of successive Fibonacci numbers converges to the Golden Ratio was imposed on us-humans had not choice in the matter. Therefore, mathematical objects, albeit imaginary, do have real properties. Second, the explanation of the unreasonable power of mathematics cannot be based entirely on evolution in the restricted sense. For example, when Newton proposed his theory of gravitation, the data that he was trying to explain were at best accurate to three significant figures. Yet his mathematical model for the force between any two masses in the universe achieved the incredible precision of better than one part in a million. Hence, that particular model was not forced on Newton by existing measurements of the motions of planets, nor did Newton force a natural phenomenon into a preexisting mathematical pattern. Furthermore, natural selection in the common interpretation of that concept does not quite apply either, because it was not the case that five competing theories were proposed, of which one eventually won. Rather, Newton's was the only game in town!

Fibonacci’s new numbering system became a hit with the merchant class and for centuries was the preeminent source for mathematical knowledge in Europe. But something equally important also happened around this time: Europeans learned of double-entry bookkeeping, picking it up from the Arabians, who’d been using it since the seventh century. Merchants in Florence and other Italian cities began applying these new accounting measures to their daily businesses. Where Fibonacci gave them new measurement methods for business, double-entry accounting gave them a way to record it all. Then came a seminal moment: in 1494, two years after Christopher Columbus first set foot in the Americas, a Franciscan friar named Luca Pacioli wrote the first comprehensive manual for using this accounting system. Pacioli’s Summa de arithmetica, geometria, proportioni et proportionalita, written in Italian rather than Latin so as to be more accessible to the public, would become the first popular work on math and accounting. Its section on accounting was so well received that the publisher eventually published it as its own volume. Pacioli offered access to the precision of mathematics. “Without double entry, businessmen would not sleep easily at night,” Pacioli wrote, mixing in the practical with the technical—Pacioli’s Summa would become a kind of self-help book for the merchant class.

Two writings of al-Hassār have survived. The first, entitled Kitāb al-bayān wa t-tadhkār [Book of proof and recall] is a handbook of calculation treating numeration, arithmetical operations on whole numbers and on fractions, extraction of the exact or approximate square root of a whole of fractionary number and summation of progressions of whole numbers (natural, even or odd), and of their squares and cubes. Despite its classical content in relation to the Arab mathematical tradition, this book occupies a certain important place in the history of mathematics in North Africa for three reasons: in the first place, and notwithstanding the development of research, this manual remains the most ancient work of calculation representing simultaneously the tradition of the Maghrib and that of Muslim Spain. In the second place, this book is the first wherein one has found a symbolic writing of fractions, which utilises the horizontal bar and the dust ciphers i.e. the ancestors of the digits that we use today (and which are, for certain among them, almost identical to ours) [Woepcke 1858-59: 264-75; Zoubeidi 1996]. It seems as a matter of fact that the utilisation of the fraction bar was very quickly generalised in the mathematical teaching in the Maghrib, which could explain that Fibonacci (d. after 1240) had used in his Liber Abbaci, without making any particular remark about it [Djebbar 1980 : 97-99; Vogel 1970-80]. Thirdly, this handbook is the only Maghribian work of calculation known to have circulated in the scientific foyers of south Europe, as Moses Ibn Tibbon realised, in 1271, a Hebrew translation.

Someday Tatiana must tell Alexander how glad she is that her sister Dasha did not die without once feeling what it was like to love. Alexander. Here he is, before he was Tatiana’s, at the age of twenty, getting his medal of valor for bringing back Yuri Stepanov during the 1940 Winter War. Alexander is in his dress Soviet uniform, snug against his body, his stance at-ease and his hand up to his temple in teasing salute. There is a gleaming smile on his face, his eyes are carefree, his whole man-self full of breathtaking, aching youth. And yet, the war was on, and his men had already died and frozen and starved... and his mother and father were gone... and he was far away from home, and getting farther and farther, and every day was his last—one way or another, every day was his last. And yet, he smiles, he shines, he is happy. Anthony is gone so long that his daughters say something must have happened to him. But then he appears. Like his father, he has learned well the poker face and outwardly remains imperturbable. Just as a man should be, thinks Tatiana. A man doesn’t get to be on the President’s National Security Council without steeling himself to some of life’s little adversities. A man doesn’t go through what Anthony went through without steeling himself to some of life’s little adversities. In this hand Anthony carries two faded photographs, flattened by the pages of the book, grayed by the passing years.

Tatiana is far away from them. “Do you want to see them with us, Grammy? Grandpa?” “We know them well,” Tatiana says, her voice catching on something. “You kids go ahead.” The grandchildren, the daughter, the son, the guests circle their heads, gaping. “Washington, look! Just look at them! What did we tell you?” Shura and Tania, 23 and 18, just married. In full bloom, on the steps of the church near Lazarevo, he in his Red Army dress uniform, she in her white dress with red roses, roses that are black in the monochrome photo. She is standing next to him, holding his arm. He is looking into the camera, a wide grin on his face. She is gazing up at him, her small body pressed into him, her light hair at her shoulders, her arms bare, her mouth slightly parted. “Grammy!” Rebecca exclaims. “I’m positively blushing. Look at the way you’re coming the spoon on Grandpa!” She turns to Alexander from the island. “Grandpa, did you catch the way she is looking at you?” “Once or twice,” replies Alexander. The other colorless photo. Tania and Shura, 18 and 23. He lifts her in the air, his arms wrapped around her body, her arms wrapped around his neck, their fresh faces tilted, their enraptured lips in a breathless open kiss. Her feet are off the ground. “Wow, Grammy,” murmurs Rebecca. “Wow, Grandpa.” Tatiana is busily wiping the granite island. “You want to know what my Washington said about you two?” Rebecca says, not looking away from the photograph. “He called you an adjacent Fibonacci pair!” She giggles. “Isn’t that sexy?” Tatiana shakes her head, despite herself glancing at Washington with reluctant affection. “Just what we need, another math expert. I don’t know what you all think math will give you.” And Janie comes over to her father who is sitting at the kitchen table, holding her baby son, bends over Alexander, leans over him, kisses him, her arm around him, and murmurs into his ear, “Daddy, I’ve figured out what I’m going to call my baby.

in computation there are two phases: generating data and transforming data. This function is very clearly performing a transformation on data, while the fibonacci function generates it. This clear demarcation adds extra clarity and extra functionality: we can move a transformative function to work on a new set of data, or perform multiple transformations on existing data. This paradigm has always been important when creating complex programs; however, generators facilitate this clearly by making generators responsible for creating the data, and normal functions responsible for acting on the generated data.

When all the stars are rotating in the correct way we will make them rotate according to the Fibonacci numbers. It will happen when we call out the correct number. When the stars are rotating according to this sequence (34/21), a disc will be created starting from your root chakra and expanding outwards – about 17 meters (55 ft). The 17th Breath Here we aim to find the correct total speed of the whole of your Merkaba (9/10 part of the speed of light). Now you have an overview of the last breaths. You will find the correct instruction on the next page. As previously, I am attaching a summary instruction, this time with all the 17 breaths of the Merkaba.

The story of numbers in the West begins in 1202, when the cathedral of Chartres was nearing completion and King John was finishing his third year on the throne of England. In that year, a book titled Liber Abaci, or Book of the Abacus, appeared in Italy. The fifteen chapters of the book were entirely handwritten; almost three hundred years would pass before the invention of printing. The author, Leonardo Pisano, was only 27 years old but a very lucky man: his book would receive the endorsement of the Holy Roman Emperor, Frederick II. No author could have done much better than that.1 Leonardo Pisano was known for most of his life as Fibonacci, the name by which he is known today. His father’s first name was Bonacio, and Fibonacci is a contraction of son-of-Bonacio. Bonacio means “simpleton” and Fibonacci means “blockhead.” Bonacio must have been something less than-a simpleton, however, for he represented Pisa as consul in a number of different cities, and his son Leonardo was certainly no blockhead.

Ingenious and original as Fibonacci’s exercises were, if the book had dealt only with theory it would probably not have attracted much attention beyond a small circle of mathematical cognoscenti. It commanded an enthusiastic following, however, because Fibonacci filled it with practical applications. For example, he described and illustrated many innovations that the new numbers made possible in commercial bookkeeping, such as figuring profit margins, money-changing, conversions of weights and measures, and—though usury was still prohibited in many places—he even included calculations of interest payments. Liber Abaci provided just the kind of stimulation that a man as brilliant and creative as the Emperor Frederick would be sure to enjoy. Though Frederick, who ruled from 1211 to 1250, exhibited cruelty and an obsession with earthly power, he was genuinely interested in science, the arts, and the philosophy of government. In Sicily, he destroyed all the private garrisons and feudal castles, taxed the clergy, and banned them from civil office. He also set up an expert bureaucracy, abolished internal tolls, removed all regulations inhibiting imports, and shut down the state monopolies. Frederick tolerated no rivals. Unlike his grandfather, Frederick Barbarossa, who was humbled by the Pope at the Battle of Legnano in 1176, this Frederick reveled in his endless battles with the papacy. His intransigence brought him not just one excommunication, but two. On the second occasion, Pope Gregory IX called for Frederick to be deposed, characterizing him as a heretic, rake, and anti-Christ. Frederick responded with a savage attack on papal territory; meanwhile his fleet captured a large delegation of prelates on their way to Rome to join the synod that had been called to remove him from power.

Fibonacci is best known for a short passage in Liber Abaci that led to something of a mathematical miracle. The passage concerns the problem of how many rabbits will be born in the course of a year from an original pair of rabbits, assuming that every month each pair produces another pair and that rabbits begin to breed when they are two months old. Fibonacci discovered that the original pair of rabbits would have spawned a total of 233 pairs of offspring in the course of a year. He discovered something else, much more interesting. He had assumed that the original pair would not breed until the second month and then would produce another pair every month. By the fourth month, their first two offspring would begin breeding. After the process got started, the total number of pairs of rabbits at the end of each month would be as follows: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233. Each successive number is-the sum of the two preceding numbers. If the rabbits kept going for a hundred months, the total number pairs would be 354,224,848,179,261,915,075. The Fibonacci series is a lot more than a source of amusement. Divide any of the Fibonacci numbers by the next higher number. After 3, the answer is always 0.625. After 89, the answer is always 0.618; after higher numbers, more decimal places can be filled in.a Divide any number by its preceding number. After 2, the answer is always 1.6. After 144, the answer is always 1.618. The Greeks knew this proportion and called it “the golden mean.” The golden mean defines the proportions of the Parthenon, the shape of playing cards and credit cards, and the proportions of the General Assembly Building at the United Nations in New York. The horizontal member of most Christian crosses separates the vertical member by just about the same ratio: the length above the crosspiece is 61.8% of the length below it. The golden mean also appears throughout nature—in flower patterns, the leaves of an artichoke, and the leaf stubs on a palm tree. It is also the ratio of the length of the human body above the navel to its length below the navel (in normally proportioned people, that is). The length of each successive bone in our fingers, from tip to hand, also bears this ratio.b

The journalist William Hoffer has remarked, “The great golden spiral seems to be nature’s way of building quantity without sacrificing quality.”2 Some people believe that the Fibonacci numbers can be used to make a wide variety of predictions, especially predictions about the stock market; such predictions work just often enough to keep the enthusiasm going. The Fibonacci sequence is so fascinating that there is even an American Fibonacci Association, located at Santa Clara University in California, which has published thousands of pages of research on the subject since 1962.

Despite Emperor Frederick’s patronage of Fibonacci’s book and the book’s widespread distribution across Europe, introduction of the Hindu-Arabic numbering system provoked intense and bitter resistance up to the early 1500s. Here, for once, we can explain the delay. Two factors were at work. Part of the resistance stemmed from the inertial forces that oppose any change in matters hallowed by centuries of use. Learning radically new methods never finds an easy welcome. The second factor was based on more solid ground: it was easier to commit fraud with the new numbers than with the old. Turning a 0 into a 6 or a 9 was temptingly easy, and a 1 could be readily converted into a 4, 6, 7, or 9 (one reason Europeans write 7 as 7).

Manetti claims he was surveying the antiquities of Rome, measuring their heights and proportions. He fails to record what method Filippo used, but he could have determined the height of columns or buildings with an upright rod. This method would have been familiar to him from Leonardo Fibonacci’s Practica geometriae (1220), a work that was studied in the schools of Florence. Or he could have employed a quadrant or, even more simply, a mirror, whose use for mensuration Fibonacci likewise describes.

Thus, the spirit of objective inquiry in understanding physical realities was very much there in the works of Muslim scientists. The seminal work on Algebra comes from Al-Khwarizmī and Fibonacci (Leonardo of Pisa) has quoted him. Al-Khwarizmī, the pioneer of Algebra, wrote that given an equation, collecting the unknowns on one side of the equation is called 'al-Jabr'. The word Algebra comes from that. He developed sine, cosine and trigonometric tables, which were later translated in the West. He developed algorithms, which are the building blocks of modern computers. In mathematics, several Muslim scientists like Al-Battani, Al-Beruni and Abul-Wafa contributed to trigonometry. Furthermore, Omar Khayyam worked on Binomial Theorem. He found geometric solutions to all 13 forms of cubic equations.

As he learned more math, Brodt made the wonder-inspiring observation that mathematical laws seemed to be Someone's intention rather than just accidents in many concepts: infinity, unity being totality, irrational numbers in general and pi in particular as it illustrates such disparate occurrences as the relationship of height to base perimeter in the Great Pyramid of Giza and the course of any meandering river (over a surface smoothed for consistency). There was also the Fibonacci Sequence, that looping string of addends which, with their sums, describes the spirals on a nautilus shell, the distribution of leaves around a tree branch, and the genealogy of ants and bees. It all seemed too orderly, too regular and consistent to have occurred by chance. So many things in the world appeared as blotches, smears, or random spikes that these mathematically explained phenomena were extraordinary--he wanted to say mystical, but he wouldn't want to be caught using that word.

There are only eight numbers. They repeat.” “That’s right, and it’s amazing that we could calculate this with only one hundred examples. Despite every block being a slightly different size and shape, calculating the ratios gets us only eight different ones, and the same thing happens when we divide the circumference by the ratio as a percentage. Furthermore, the eight unique numbers that result from that calculation are all Fibonacci numbers.

Why, just that the Fibonacci numbers have to be significant. Because of the ratios in the structure as a whole, you see. I think the builders were trying to draw our eyes to the fact that there’s an alphabet here. We can’t see all of it, because we don’t have enough data. But I’d be willing to bet that if we arranged these Fib numbers by location of the blocks they came from, we’d see something that looks random but is actually some representation of a written language.

I added new fields to the database, with the calculations your colleague applied to the data. Now we are able to see the result as soon as I have put the raw data into the record,” Raj was saying. As he typed, a dizzying array of numbers in rows and columns marched across the screen. A few more keystrokes, and the data arranged itself into a chart, showing the final calculation in colored numbers. Sarah and Daniel looked closer, to notice that the different colors always represented the same number, red for five, green for eight, and so on. The sequences, clearly Fibonacci numbers, went no higher than thirty-four. “How many of these blocks have you finished, Raj?” Daniel asked. “All of them in the passageway, both sides.” “And yet, not counting zero or the repeated one, we have only eight numbers, the highest being thirty-four. Could we have been mistaken about the message? It doesn’t seem like enough.

Look, the numbers up to eight are expressed everywhere in the pyramid, all the angles and measurements, everything. That was the builders saying, ‘look at this, we’ve left you a message if you can interpret this’. Now we’ve got three more numbers in the sequence, thirteen, twenty-one and thirty-four. I don’t know of any alphabet, ancient or modern, that had so few as thirteen characters, so I think it’s just that they chose Fibonacci numbers to get our attention and then point to the alphabet; the thirteen has no significance. I can’t see any, at least at this time. But twenty-one, and thirty-four, now we’re getting somewhere. We just have to find the alphabet that has one of those numbers of letters, and we’ll know what language they were speaking.

The book provided the first really detailed Latin account of the modus Indorum, the method of the Indians, which Fibonacci believed was superior even to the method of Pythagoras. It brought to its readers the Indo-Arabic numbering system, spelled out by Khwarizmi, and before him Brahmagupta. Al-sifr is just a translation of the Sanskrit sunya, the concept of the void, which Brahmagupta first applied to zero.

This was in turn related to the Golden Ratio, which Fibonacci realised was something which kept reappearing in nature: the spiralling of the chambers of the nautilus shell, for example, obeys this ratio.59 Although Fibonacci’s Liber Abaci contains the earliest known description of the sequence outside India, the sequence had been described by Aryabhata as early as the sixth century.

But there is no doubt as to what happened to Nalanda’s near neighbour, the great monastery of Odantapura. In 1202, the same year that the young Fibonacci returned from Algeria to Italy, Bakhtyar Khalji’s Turkish troops attacked the monastery, a royal foundation. After slaughtering its inhabitants, they found vast heaps of manuscripts within one of the monastic towers. ‘Great plunder fell into the hands of the victors,’ recorded one chronicler. ‘The inhabitants of the place were Brahmanas with shaven heads. They were put to death. Large numbers of books were found there, and when the Mohammadans saw them, they called for some person to explain their contents. But all of the men had been killed, and there was no one left who could read them. It was discovered that the whole fort and city was actually a place of learning.’83 The monastery was then turned into a Turkish fortress, garrisoned with soldiers and commanded by a Turkish general.84
