Why does Graham's number need its own notation? How many grains of sand would fill the universe? What is the connection between the Golden Ratio and sunflowers? Why is 999 more than a distress call? All these questions and a host more are answered in this fascinating book, which has now been newly revised, with nearly 200 extra entries and some 250 additions to the original entries. From minus one and its square root, via cyclic, weird, amicable, perfect, untouchable and lucky numbers, aliquot sequences, the Cattle problem, Pascal's triangle and the Syracuse algorithm, music, magic and maps, pancakes, polyhedra and palindromes, to numbers so large that they boggle the imagination, all you ever wanted to know about numbers is here. There is even a comprehensive index for those annoying occasions when you remember the name but can't recall the number.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp\u003ePerfect for fans of Encyclopedias \u0026amp; Subject Guides, Reference, Popular Mathematical Theory, Mathematics References, Higher Mathematical Education.\u003c\/p\u003e\n\u003cdiv class=\"book-highlights\"\u003e\n\u003ch3\u003eHighlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEasy to enjoy: 256 pages · Paperback\u003c\/li\u003e\n\u003cli\u003eBy Wells, David\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"book-details\"\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISBN:\u003c\/strong\u003e 9780140261493\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthor:\u003c\/strong\u003e Wells, David\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat:\u003c\/strong\u003e Paperback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePages:\u003c\/strong\u003e 256\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLanguage:\u003c\/strong\u003e English\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePublication date:\u003c\/strong\u003e 4 September 1997\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Used – Good\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"book-about\"\u003e\n\u003ch3\u003eAbout the authors\u003c\/h3\u003e\n\u003cp\u003eWells, David and David Wells and David G.
