This book covers new ground on Fibonacci sequences and the well-known Fibonacci numbers. It will appeal to research mathematicians wishing to advance the new ideas themselves, and to recreational mathematicians, who will enjoy the various visual approaches and the problems inherent in them.There is a continuing emphasis on diagrams, both geometric and combinatorial, which helps to tie disparate topics together, weaving around the unifying themes of the golden mean and various generalizations of the Fibonacci recurrence relation.Very little prior mathematical knowledge is assumed, other than the rudiments of algebra and geometry, so the book may be used as a source of enrichment material and project work for college students. A chapter on games using goldpoint tiles is included at the end, and it can provide much material for stimulating mathematical activities involving geometric puzzles of a combinatoric nature.

Red Cashion is quite possibly the most universally liked referee in NFL history. Fans loved him; coaches respected him; players joked with him; and league executives applauded him for adding flavor with his trademark "first dooowwwnnn" call. Long before he worked three Super Bowls and became the only official ever to be named the All-Madden team, Cashion nearly gave up on his NFL dreams. He began officiating junior high games in 1952 while still a student at Texas A&M, but he was fired by the Southland Conference for being too robotic and dull. Nevertheless, Cashion scheduled a January 1972 trip to New York to meet with Art McNally, the Director of Officiating for the NFL. McNally listened politely and then delicately told Cashion there were no openings. Cashion left that day with a broken heart, believing the dream was officially over. But an NFL official was killed during the summer of '72 and McNally offered Cashion the job because he'd taken such a bold risk by traveling to New York. The rest is NFL history, as Cashion's No. 43 uniform became as familiar to many fans at NFL stadiums as some of the players. Red's feel-good life story packs a powerfully enthusiastic punch.

The Common European Framework of Reference for Languages (CEF or CEFR) was put together by the Council of Europe as a way of standardising the levels of language exams in different regions. It is very widely used internationally and all important exams are mapped to the CEFR. There are six levels: A1, A2, B1, B2, C1, C2. A2 Waystage An ability to deal with simple, straightforward information and begin to express oneself in familiar contexts. A2 Flyers, formerly known as Cambridge English: Flyers (YLE Flyers), is one of our Cambridge English Qualifications. It is a fun, activity-based English tests for children. A2 Flyers is the third of three Cambridge English Qualifications designed for young learners. These tests introduce children to everyday written and spoken English and are an excellent way for them to gain confidence and improve their English. A2 Flyers is corresponding with A2 Waystage under CEFR. By referring Cambridge dictionary online and other resource, we collect 1560 Vocabulary for A2 Flyers. We give the English and Chinese explanations. If there are more than one explanations under each phrase, we choose only the ones under A2 classification.
