Paperback. Condición: Good. This is the dramatic and inspirational first-person story of theoretical physicist, Dr. Ronald Mallett, who recently discovered the basic equations for a working time machine that he believes can be used as a transport vehicle to the past. Combining elements of Rocket Boys and Elegant Universe, Time Traveler follows Mallett's discovery of Einstein's work on space-time, his study of Godel's work on a solution of Einstein's equation that might allow for time travel, and his own research in theoretical physics spanning thirty years that culminated in his recent discovery of the effects of circulating laser light and its application to time travel. The foundation for Mallett's historic time-travel work is Einstein's theory of general relativity, a sound platform for any physicist. Through his years of reading and studying Einstein, Mallett became a buff well before he had any notion of the importance of the grand old relativist's theories to his own career. One interesting subtext to the story is Mallett's identification with, and keen interest in, Einstein. Mallett provides easy-to-understand explanations of the famous physicist's seminal work.…

But right now, he's simply T'Challa--the young prince. Life is comfortable for twelve-year-old T'Challa in his home of Wakanda, an isolated, technologically advanced African nation. When he's not learning how to rule a kingdom from his father--the reigning Black Panther--or testing out the latest tech, he's off breaking rules with his best friend, M'Baku. But as conflict brews near Wakanda, T'Challa's father makes a startling announcement: he's sending T'Challa and M'Baku to school in America. This is no prestigious private academy--they've been enrolled at South Side Middle School in the heart of Chicago. Despite being given a high-tech suit and a Vibranium ring to use only in case of an emergency, T'Challa realizes he might not be as equipped to handle life in America as he thought. Especially when it comes to navigating new friendships while hiding his true identity as the prince of a powerful nation, and avoiding Gemini Jones, a menacing classmate who is rumored to be involved in dark magic.

Countries studied include the United States, Switzerland, Australia, Austria, and Germany as examples of developed industrial societies; India and Malaysia as examples of multilingual and multicultural federations; Belgium and Spain as examples of emerging federal systems that illustrate bicommunal and asymmetrical approaches; and Czechoslovakia and Pakistan as examples of bicommunal federations that have failed. Watts compares the interaction of social diversity and political institutions, distribution of powers and finances, processes contributing to flexibility or rigidity in adjustment, extent of internal symmetry or asymmetry, degree of centralization and decentralization, character of representation in federal institutions, role of constitutions and courts, provisions for constitutional rights and secession, and pathology in federations.…
