eng The Most Astonishing Number by Mario Livio

Indeed this is also a most astonishing book telling the story of a number. In bibliographical terms this book is mathematics, or slightly more narrowly history of mathematics. Nota bene! The number is not the well-known Pi (3,14..), related with circle, but equally well-known, not as a number but as ratio of long and short edge of an ideal four corner surface. Everybody knows and has a conception of what is a Golden Ratio without ever thinking it as a number. At least I bumped to the number reading this book, first time in my over 75 years of life. The magic number is PHI (1,618), the ratio of the long side to short side of any Golden cut surface. What is so special about that innocent-looking number?

Read this book and you will be astonished. As if the whole Universe would be planned on the basis of this magic number: all 'natural' dimensions fron snow-flakes to the form of galaxies, masterpieces of painting, sculpture and music have this Golden ratio as the basic measure of their inner proportions. We seek it instinctively everywhere and are disappointed, if we do not find it. As an example I am extremely irritated of the brute deviation from this ideal of the format of paper journals; in addition to being unpleasant looking, they also are clumsily flabby for holding in hands.

Despite of presenting the innocent looking simple numbeer Phi (with alternative formulas behind it) this book plunges right away to the deepest mysteries of mathematics referring to dozens, hundreds of authorities. And yet, you will have no difficulty reading and understanding the text. High level mathematics is usually thought as pages full of formulas and dissertations of 20 pages, which very few persons understand. This book is not that way, although it goes far beyond mathematics requiring technical knowledge and skills. Just that is the fascination of the book. Embracing structures from flowers to houses and galaxies you get a fantastic feeling of better understanding what you see. Also another very rare feature is included. The host of personalities contributing to this discovery of hidden secrets of our world view are presented on everyday grass root level. Such well-known as Pythagoras, Newton, Gauss, Kepler, Einstein along with many less known but very important geniuses. Believe or not you have the feeling of meeting and chatting with them persoanlly. A real magician this Mario Livio, five stars without any hesitation. Grateful to my friend Viljo, class mate beyond 60 years, who introduced this author to me. Reading already a second Amazon book by Livio, about The Impossible Equation.

Review in English

fin Ihmeellinen suhdeluku

Todellakin tämä on myös kaikkein hämmästyttävä kirja kertoo tarinan useita. Vuonna bibliografiset kannalta tämä kirja on matematiikkaa, tai hieman suppeammin historian matematiikka. Huom! Numero ei ole tunnettu Pi (3,14 ..), liittyy ympyrä, mutta yhtä hyvin tiedossa, eikä sillä useat vaan suhde pitkä ja lyhyt reuna ihanteellinen neljä nurkka pinta. Kaikki tietävät ja on käsitys siitä, mitä on Golden Ratio koskaan ajatellut sitä lukuna. Ainakin Törmäsin lukumäärään luet tätä kirjaa, ensimmäinen kerta yli 75 vuotta elämää. Maaginen numero on PHI (1618), suhde pitkä sivu lyhyeen sivuun minkään Golden leikkauspinnan. Mikä on niin erikoista, että viattoman näköinen numero?

Lue tämä kirja ja sinun on hämmästynyt. Ikään kuin koko maailmankaikkeus suunnitellaan perusteella tämä taika numero: kaikki "luonnollinen" mitat rajoista lumi-hiutaleita muotoon galakseja, mestariteoksia maalaus, kuvanveisto ja musiikki on tämä Golden suhde kuin perus mittana niiden sisäinen mittasuhteet . Haemme sen vaistomaisesti kaikkialla ja ovat pettyneitä, jos emme löydä sitä. Esimerkkinä olen äärimmäisen ärtynyt ja raa'alla poikkeama tästä ihanteellisen muodon paperin lehtiä; sen lisäksi, että epämiellyttävä näköinen, ne ovat myös kömpelösti vetelä varten tilalla käsissä.

Huolimatta esitellä viattoman näköisen yksinkertainen numbeer Phi (vaihtoehtoisia kaavoja takana) tämä kirja sukeltaa heti syvimpiin mysteereihin matematiikan viitaten kymmeniä, satoja viranomaiset. Ja vielä, et ei ole vaikea lukea ja ymmärtää tekstiä. Korkean tason matematiikkaa on yleensä ajateltu kuin sivut täynnä kaavoja ja väitöskirjoista 20 sivua, joka hyvin harvat henkilöt ymmärtää. Tämä kirja ei ole näin, vaikka se menee paljon pidemmälle matematiikka edellyttää teknistä osaamista. Vain, että on kiehtovaa kirjan. Embracing rakenteita kukkia taloja ja galaksit saat fantastinen tunne ymmärtää paremmin, mitä näet. Myös toinen hyvin harvinainen ominaisuus on mukana. Isäntä persoonallisuuksia edistää tätä löytö piilotetut salaisuudet maailmamme mieltä esitellään jokapäiväiseen ruohonjuuritasolla. Tällaiset tunnetut Pythagoraana, Newton, Gauss, Kepler, Einstein yhdessä monien vähemmän tunnettuja, mutta erittäin tärkeä neroja. Uskokaa tai et on tunne kokous ja jutteleminen heidän persoanlly. Todellinen taikuri tämän Mario Livio, viisi tähteä epäröimättä. Kiitollinen ystäväni Viljo, luokan mate yli 60 vuotta joka esitteli tämä kirjailija minulle. Lukeminen jo toinen Amazon kirja Livio, noin Impossible yhtälö.
