Who can calculate the orbit of his own soul? "Oscar Wilde's" De Profundis "Want to see what the Universe ... CHAOS is a well-ordered and nature is all here: simple ... complex at the same time poetic ... There is no ... document attesting to the true date of birth (it seems he was born in 1170, died in 1250 in Pisa, Italy) sacks sandwiches tempe Leonardo Fibonacci da Pisa said or Bigollo (which means traveler). know only that in young age is "in pueritia mea" he writes in Liber ... Abacie had accompanied him to lie his father William, who in the customs of the city Maghreb carried out the functions of "publicus scribe pro Pisanis sacks sandwiches tempe mercatoribus", ie notary who took care assistance sacks sandwiches tempe to merchants and perhaps even had positions of representation. Here the young Leonardo learned the abacus math, perhaps no more than the basics if you have to give credence to his own story, where he says he was at school abacus "to aliquot dies", the letter: for some days. But once familiarizzatosi with the techniques of the Arabic numerals, will not cease to accumulate more knowledge, seizing what was known in the places where his work took him, or more probably his desire to travel and knowledge: in Egypt, in Syria, Greece, Sicily, in Provence; in short, throughout the Mediterranean.
The result of these trips and these studies will be in 1202 the publication of the Liber Abaci, followed a few years away from geometriae Practice (1220), and some other minor works per mole, but not for content: the Liber quadratorum, the Flos, both published in 1225, and the Epistle to magistrum Theodorum, of uncertain date, but also composed around those years. Other writings, including a treaty minor way, perhaps a reduced and simplified sacks sandwiches tempe version of the Liber Abaci, and a Commentary on Book X of Euclid, have gone lost.
We think we are highly evolved beings, and enjoy the amazing technology of today the illusion of having reached high points of rationality, creativity, imagination, etc.., Etc.. The Science undoubtedly goes on, but I fear it is the result of an ever-shrinking minority ... little by little sacks sandwiches tempe the malpractice and the idiocy of the media may also defeat it. We hope in young people, sacks sandwiches tempe the only ones who have the opportunity and the ability to reverse the mental decay. This outburst sacks sandwiches tempe only serves sacks sandwiches tempe to introduce a character to say the least exceptional: Leonardo Fibonacci. Did not discover anything extremely useful to humans sacks sandwiches tempe nor has contributed to the knowledge of what surrounds us, but he insinuated sacks sandwiches tempe doubts and emotions about the rules that Nature is so determined sacks sandwiches tempe to follow. He was a mathematician, but what matters most is that he lived in an era of human history quite anonymous. Born in Pisa (it will be a case? Even Galileo of Pisa ...), it is relatively famous for his "numbers". Let me surprise that a man of the Middle sacks sandwiches tempe Ages has been able to conceive in 1202 an extraordinary regularity in a series constructed very simply. We write these numbers, then: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 ... What link have between sacks sandwiches tempe them? Simple: each is the sum of the previous two. 1 + 1 = 2, 1 +2 = 3, 2 + 3 = 5, 3 + 5 = 8, etc. ... etc.. "Well?", You say, "I do not look like anything special ...!" Let us, then, the relationship between these numbers 1: 2 = 0.5 2: 3 = 0.667 3: 5 = 0.6 5: 8 = 0625 = 8:13 34:55 = 0.615 ... 0.618 After small changes the ratio becomes constant and always sacks sandwiches tempe equal to 0.618. sacks sandwiches tempe In mathematical terms, the limit of this ratio tends to 0.618.
A number sacks sandwiches tempe is not any, but already well-known in antiquity and linked to all forms of art. Comes from the irrational number ((5) 1 / 2-1) / 2 which is universally known as the Golden Number, and is defined as the ratio of the Golden Section, which is considered as the universal law of harmony.
The Parthenon is enclosed in a golden rectangle, that is, such that the longer side divided by the shorter one is equal to the number of gold and its structure are different golden sections that can be observed and the same proportions gold find in the Renaissance , whose windows are rectangles gold or closer to us in the construction of Le Corbusier.
A few examples: the Egyptian pyramids, the Parthenon, the Erechtheion caryatids, are defined through a golden rectangle whose proportions are just given by the golden ratio. And it is also easy to build both to the small than to the large. If we start from a golden rectangle, just draw a square
