The Fibonacci sequence, starting with two ones and continuing with each number being the sum of the two preceding ones (1, 1, 2, 3, 5, 8, 13, 21, etc.), is a captivating pattern in mathematics. This sequence is not merely a curiosity; it appears in various natural structures, such as the arrangement of whorls on pinecones and the branching of certain plant stems, highlighting the profound mathematical foundation of the natural world. Two experienced math educators guide readers through the intriguing implications of Fibonacci numbers, beginning with the history of an Italian mathematician who popularized Arabic numerals in the West. They illustrate, with diagrams, the astonishing links between Fibonacci numbers and natural forms like pineapples, sunflowers, and daisies. The authors also explore the sequence's presence in art, architecture, the stock market, and other cultural areas, along with its derivative, the "golden ratio." In mathematics, they showcase its vast applications in probability, number theory, geometry, algebra, and Pascal's triangle. This engaging book is accessible to even the most math-averse readers, allowing them to appreciate the elegance of mathematics and its remarkable relevance in both natural and cultural contexts.

In his latest book, mathematician Alfred S. Posamentier provides easily understandable, easily presentable and easily replicated tricks that one can do with mathematics.

If you remember anything about high school geometry class, it's probably doing proofs. But geometry is more than axioms, postulates, theorems, and proofs. It's the science of beautiful and extraordinary geometric relationships--most of which is lost in high school classrooms w...

"Two veteran math educators concisely profile leading mathematicians throughout history highlighting their often unusual personalities and lives while giving average readers insights into the importance of their mathematical discoveries."--

In this delightful layperson's introduction to one of math's most interesting phenomena, Drs. Posamentier and Lehmann review pi's history from prebiblical times to the 21st century, the many amusing and mind-boggling ways of estimating pi over the centuries, quirky examples of obsessing about pi, and useful applications of pi in everyday life, including statistics.

Ta książka to zabawna i intrygująca opowieść o matematycznych błędach, które - wbrew temu, co moglibyśmy sądzić - przynoszą niekiedy całkiem interesujące rezultaty, przyczyniając się do głębszego zrozumienia matematyki. Bywa również inaczej - czasami nawet właściwe metody mogą prowadzić do absurdalnych, aczkolwiek bardzo ciekawych wyników. Matematyka jest piękna, nawet wtedy, gdy popełniamy błędy. Aby wybrać się w tę niezwykłą podróż przez matematyczne omyłki wcale nie trzeba spełniać wygórowanych wymagań - wystarczy znajomość podstaw! Mając Posamentiera i Lehmanna za przewodników, możemy być pewni, że po jej zakończeniu będziemy o wiele lepiej rozumieli tę podstawową, niezwykle ważną gałąź nauki - język, którym przemawia do nas rzeczywistość.
