Pagoo Pa

From the moment of his birth, Pagoo the hermit crab learns to rely on his "instint" in order to survive to adulthood in his tide pool home.

This textbook is suitable for a one-semester introduction to General Relativity for advanced undergraduates in physics and engineering. The book is concise so that the entire material can be covered in the one-semester time frame. Many of the calculations are done in detail, without difficult mathematics, to help the students. Though concise, the theory development is lucid and the readers are exposed to possible analytic calculations.In the second edition, the famous twin paradox with acceleration is solved in full from the accelerated observer's frame. The findings of the Event Horizon Telescope (EHT) collaboration, who captured the first ever image of a black hole, are discussed in detail. The geodetic and frame drag precessions of gyroscopes in orbit about a rotating Earth are worked out and the Gravity Probe B (GPB) experiment is discussed. Also in the second edition are some new exercise problems.Resources are provided to instructors who adopt this textbook for their courses. Adopting instructors can print and copy portions of these resources solely for their teaching needs. All instructional resources are furnished for informational use only, and are subject to change without notice.

Mixing elementary results and advanced methods, Algebraic Approach to Differential Equations aims to accustom differential equation specialists to algebraic methods in this area of interest. It presents material from a school organized by The Abdus Salam International Centre for Theoretical Physics (ICTP), the Bibliotheca Alexandrina, and the International Centre for Pure and Applied Mathematics (CIMPA).

The most complete and up-to-date dictionary of Lakota available, this new edition of Eugene Buechel's classic dictionary contains over thirty thousand entries and will serve asøan essential resource for everyone interested in preserving, speaking, and writing the Lakota language today. This new comprehensive edition has been reorganized to follow a standard dictionary format and offers a range of useful features: both Lakota-to-English and English-to-Lakota sections; the grouping of principal parts of verbs; the translation of all examples of Lakota word usage; the syllabification of each entry word, followed by its pronunciation; and a lucid overview of Lakota grammar. This monumental new edition celebrates the vitality of the Lakota language today and will be a valuable resource for students and teachers alike.

With an emphasis on techniques, this volume focuses on the applications of basic mathematics and differential and integral calculus in the field of business, economics and the life and social sciences. All mathematical theorems, proofs and concepts are described intuitively and then mathematically. Reorganized and rewritten material includes chapters on exponentials and logarithms, curve sketching and optimization, application sections of straight lines and quadratic inequalities. A new section on difference equations and expanded coverage of differential equations is included.

This research level monograph reflects the current state of the field and provides a reference for graduate students entering the field as well as for established researchers.
