THE OFFICIAL BOOK OF THE FIRST EARTH DAY. Speaking for the Earth is written by United States Senate Candidate, Howard Hughes aide, and world-renowned environmentalist John Meier. It was written by Meier in 1970 for the first Earth Day. In 1970 Meier was at the forefront of the environmental movement, including having resided on United States President Richard Nixon’s Task Force on Resources and Environment and receiving international acclaim from Countries for his work on ...

Drums beat in rhythm to the steps of a giant as he walks towards the young man. Soldiers smash their swords to shields in sync with the drums, a throbbing pressure that resonates over the valley. Young, small, scared, the boy fights against the fears within that are telling him to turn and run. Why stay and fight? Why stand and die? The questions threaten to smother him before he can be used for the glory of the King. But this physical confrontation barely scratches the surface. The battle...

Exploring Mathematics gives students experience with doing mathematics - interrogating mathematical claims, exploring definitions, forming conjectures, attempting proofs, and presenting results - and engages them with examples, exercises, and projects that pique their interest. Written with a minimal number of pre-requisites, this text can be used by college students in their first and second years of study, and by independent readers who want an accessible introduction to theoretical math...

In the 1980s and 1990s, forty-nine women in the Seattle area were brutally murdered, their bodies dumped along the Green River and Pacific Highway South in Washington State. Despite an exhaustive investigation—even serial killer Ted Bundy was consulted to assist with psychological profiling—the sadistic killer continued to elude authorities for nearly twenty years.Then, in 2001, after mounting suspicion and with DNA evidence finally in hand, King County police charged a fifty-two-y...

Lewis Carroll's books have delighted children and adults for generations, but behind their exuberant fantasy and delightful nonsense was the mind of a brilliant mathematician.Now his forgotten achievements in the world of numbers are brought to light by acclaimed author and mathematician Robin Wilson. Here he explores the curious imagination of a man whose pioneering work at Oxford University included investigations into voting patterns and tennis seeding, who dreamt up numerical c...

Löwenheim's theorem reflects a critical point in the history of mathematical logic, for it marks the birth of model theory--that is, the part of logic that concerns the relationship between formal theories and their models. However, while the original proofs of other, comparably significant theorems are well understood, this is not the case with Löwenheim's theorem. For example, the very result that scholars attribute to Löwenheim today is not the one that Skolem--a logician raised in the ...

This book presents diverse topics in mathematical logic such as proof theory, meta-mathematics, and applications of logic to mathematical structures. The collection spans the first 100 years of modern logic and is dedicated to the memory of Irving Anellis, founder of the journal 'Modern Logic', whose academic work was essential in promoting the algebraic tradition of logic, as represented by Charles Sanders Peirce. Anellis’s association with the Russian logic community introduced their sch...

Hilbert's Program was founded on a concern for the phenomenon of paradox in mathematics. To Hilbert, the paradoxes, which are at once both absurd and irresistible, revealed a deep philosophical truth: namely, that there is a discrepancy between the laws accord ing to which the mind of homo mathematicus works, and the laws governing objective mathematical fact. Mathematical epistemology is, therefore, to be seen as a struggle between a mind that naturally works in one way and a reality that...

The book offers a comprehensive survey of intuitionistic fuzzy logics. By reporting on both the author’s research and others’ findings, it provides readers with a complete overview of the field and highlights key issues and open problems, thus suggesting new research directions. Starting with an introduction to the basic elements of intuitionistic fuzzy propositional calculus, it then provides a guide to the use of intuitionistic fuzzy operators and quantifiers, and lastly presents state-o...

This volume brings together a group of logic-minded philosophers and philosophically oriented logicians to address a diversity of topics on the structural analysis of non-classical logics. It mainly focuses on the construction of different types of models for various non-classical logics of current interest, including modal logics, epistemic logics, dynamic logics, and observational predicate logic. The book presents a wide range of applications of two well-known approaches in current rese...

This book presents four mathematical essays which explore the foundations of mathematics and related topics ranging from philosophy and logic to modern computer mathematics. While connected to the historical evolution of these concepts, the essays place strong emphasis on developments still to come.The book originated in a 2002 symposium celebrating the work of Bruno Buchberger, Professor of Computer Mathematics at Johannes Kepler University, Linz, Austria, on the occasion of his 6...
