Book Description
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.

Book Description
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.

Book Description
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. This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand

Book Description
Making an artificial brain is not a part of artificial intelligence. It will be a revolutionary journey of mankind exploring a science where one cannot write an equation, a material will vibrate like geometric shape, and then those shapes will change to make decisions. Geometry of silence plays like a musical instrument to mimic a human brain; our thoughts, imagination, everything would be a 3D shape playing as music; composing music would be the brain’s singular job. For a century, the Turing machine ruled human civilization; it was believed that irrespective of complexity all events add up linearly. This book is a thesis to explore the science of decision-making where events are 3D-geometric shapes, events grow within and above, never side by side. The book documents inventions and discoveries in neuroscience, computer science, materials science, mathematics and chemistry that explore the possibility of brain or universe as a time crystal. The philosophy of Turing, the philosophy of membrane-based neuroscience and the philosophy of linear, sequential thought process are challenged here by considering that a nested time crystal encompasses the entire conscious universe. Instead of an algorithm, the pattern of maximum free will is generated mathematically and that very pattern is encoded in materials such that its natural vibration integrates random events exactly similar to the way nature does it in every remote corner of our universe. Find how an artificial brain avoids any necessity for algorithm or programming using the pattern of free will.

Book Description
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.

Book Description
In this innovative study, Crystal Sanders explores how working-class black women, in collaboration with the federal government, created the Child Development Group of Mississippi (CDGM) in 1965, a Head Start program that not only gave poor black children access to early childhood education but also provided black women with greater opportunities for political activism during a crucial time in the unfolding of the civil rights movement. Women who had previously worked as domestics and sharecroppers secured jobs through CDGM as teachers and support staff and earned higher wages. The availability of jobs independent of the local white power structure afforded these women the freedom to vote in elections and petition officials without fear of reprisal. But CDGM's success antagonized segregationists at both the local and state levels who eventually defunded it. Tracing the stories of the more than 2,500 women who staffed Mississippi's CDGM preschool centers, Sanders's book remembers women who went beyond teaching children their shapes and colors to challenge the state's closed political system and white supremacist ideology and offers a profound example for future community organizing in the South.
