Time Crystal

This book provides the first comprehensive description of time crystals which have a repeating structure in time. It introduces the fundamental concepts behind time crystals and explores the many different branches of this new research area. The book starts with the original idea of the time crystallization in quantum systems as introduced by Wilczek and follows the development of the field up to the present day. Both spontaneous formation of crystalline structures in time and concepts of the condensed matter physics in the time domain, ranging from Anderson localization in time to many-body systems with exotic interactions, are described. The prospect of creation of novel objects by means of time engineering is also presented. The book assumes knowledge of quantum mechanics to the graduate level. It serves as a valuable reference with pointers to future research directions for graduate students and senior scientists alike.

What Is Time Crystal In condensed matter physics, a time crystal is a quantum system of particles whose lowest-energy state is one in which the particles are in repetitive motion. The system cannot lose energy to the environment and come to rest because it is already in its quantum ground state. Because of this the motion of the particles does not really represent kinetic energy like other motion, it has "motion without energy". Time crystals were first proposed theoretically by Frank Wilczek in 2012 as a time-based analogue to common crystals whereas the atoms in crystals are arranged periodically in space, the atoms in a time crystal are arranged periodically in both space and time. Several different groups have demonstrated matter with stable periodic evolution in systems that are periodically driven. In terms of practical use, time crystals may one day be used as quantum memories.

In the town of Hobble, October never ends. As soon as Hallows Eve is over, the calendars turn back to October 1st, and the enchanted wonders begin again . . .In this first adventure of the October series, Notch Cricklewood is bored by his life at the Museum Of Wonders, where he lives amongst statues and relics from the distant past. Though his father and grandfather hope for him to apprentice with them at the museum, Notch is hungry to live his own adventures and make history.When all the children in Hobble begin to mysteriously disappear, Notch sets out to solve the vanishings in order to make a name for himself. But when a member of the Vothlor army kills someone close to him, the new war becomes much more personal. Notch's persistence soon leads him on a quest to find the legendary Time Crystal-an ancient relic that gives its possessor the power to change the course of history. If he can find the crystal, he believes he can save the missing kids and bring the dead back to life.But what if the Vothlor find it first?THE TIME CRYSTAL is Book 1 in the innovative new OCTOBERS series by J.H. Reynolds and Craig Cunningham. Journey through the same October through four different perspectives. In addition to THE TIME CRYSTAL, read THE HERMIT'S MANSION (Book 2), THE WATCHTOWER SECRET (Book 3), and the PROTECTOR'S EMERALD (Book 4) to solve all the mysteries of the Vanishing, and embark upon an adventure unlike any you've taken before.

The growth of ice crystals as a function of depth and time in polar firn and glacier ice has been investigated at a number of locations in Antarctica and Greenland. Thin sections of snow and ice were used to measure crystal size variations. Crystal growth rates are strongly temperature dependent with growth being very much retarded at the lower englacial temperatures. At Camp Century, Greenland, where the firn temperature is -24C (constant below 10 m depth) crystals grow approximately 23 times faster than at Plateau Station, Antarctica, where the in situ temperature is -57C.

The Rime petrose, Dante's powerful lyrics about a woman as beautiful and as hard as a precious stone, are generally acknowledged to be an important moment in his stylistic development. In this full-length investigation of the poetics of the petrose and of their relation to TheDivine Comedy, Robert M. Durling and Ronald L. Martinez uncover new material, especially from medieval science (astrology and mineralogy), philosophy, and theology. The authors argue that the Rime petrose represent a major turning point in Dante's conception of a "microcosmic poetics" that became the fundamental mode of the Commedia. They demonstrate how Dante here attempts his first full account of his relation to the universe as a whole. This work offers many insights into the intrinsic significance of these remarkable poems and their place in Dante's development. Especially far-reaching are the implications for the interpretation of TheDivine Comedy.Time and the Crystal will interest not only students of Dante but also intellectual historians, historians of science, students of poetics and poetic theory, and all those interested in medieval literature.

In the past decade, the field of comparative cognition has grown and thrived. No less rigorous than purely behavioristic investigations, examinations of animal intelligence are useful for scientists and psychologists alike in their quest to understand the nature and mechanisms of intelligence. Extensive field research of various species has yielded exciting new areas of research, integrating findings from psychology, behavioral ecology, and ethology in a unique and wide-ranging synthesis of theory and research on animal cognition. The Oxford Handbook of Comparative Cognition contains sections on perception and illusion, attention and search, memory processes, spatial cognition, conceptualization and categorization, problem solving and behavioral flexibility, and social cognition processes including findings in primate tool usage, pattern learning, and counting. The authors have incorporated findings and theoretical approaches that reflect the current state of the field. This comprehensive volume will be a must-read for students and scientists who want to know about the state of the art of the modern science of comparative cognition.
