The characteristic – Planck – energy scale of quantum gravity makes experimental access to the relevant physics apparently impossible. Nevertheless, low energy experiments linking gravity and the quantum have been undertaken: the Page and Geilker quantum Cavendish experiment, and the Colella-Overhauser-Werner neutron interferometry experiment, for instance. However, neither probes states in which gravity remains in a coherent quantum superposition, unlike – it is claimed – recent proposals. In essence, if two initially unentangled subsystems interacting solely via gravity become entangled, then theorems of quantum mechanics show that gravity cannot be a classical subsystem. There are formidable challenges to such an experiment, but remarkably, tabletop technology into the gravity of very small bodies has advanced to the point that such an experiment might be feasible in the near future. This Element explains the proposal and what it aims to show, highlighting the important ways in which its interpretation is theory-laden.

Scientists, theologians, and philosophers have all sought to answer the questions of why we are here and where we are going. Finding this natural basis of life has proved elusive, but in the eloquent and creative Into the Cool, Eric D. Schneider and Dorion Sagan look for answers in a surprising place: the second law of thermodynamics. This second law refers to energy's inevitable tendency to change from being concentrated in one place to becoming spread out over time. In this scientific tour de force, Schneider and Sagan show how the second law is behind evolution, ecology, economics, and even life's origin. Working from the precept that "nature abhors a gradient," Into the Cool details how complex systems emerge, enlarge, and reproduce in a world tending toward disorder. From hurricanes here to life on other worlds, from human evolution to the systems humans have created, this pervasive pull toward equilibrium governs life at its molecular base and at its peak in the elaborate structures of living complex systems. Schneider and Sagan organize their argument in a highly accessible manner, moving from descriptions of the basic physics behind energy flow to the organization of complex systems to the role of energy in life to the final section, which applies their concept of energy flow to politics, economics, and even human health. A book that needs to be grappled with by all those who wonder at the organizing principles of existence, Into the Cool will appeal to both humanists and scientists. If Charles Darwin shook the world by showing the common ancestry of all life, so Into the Cool has a similar power to disturb-and delight-by showing the common roots in energy flow of all complex, organized, and naturally functioning systems. "Whether one is considering the difference between heat and cold or between inflated prices and market values, Schneider and Sagan argue, we can apply insights from thermodynamics and entropy to understand how systems tend toward equilibrium. The result is an impressive work that ranges across disciplinary boundaries and draws from disparate literatures without blinking."-Publishers Weekly

Highlighting collaborative archaeological research that centers the enduring histories of Native peoples in North America Challenging narratives of Indigenous cultural loss and disappearance that are still prevalent in the archaeological study of colonization, this book highlights collaborative research and efforts to center the enduring histories of Native peoples in North America through case studies from several regions across the continent. The contributors to this volume, including Indigenous scholars and Tribal resource managers, examine different ways that archaeologists can center long-term Indigenous presence in the practices of fieldwork, laboratory analysis, scholarly communication, and public interpretation. These conversations range from ways to reframe colonial encounters in light of Indigenous persistence to the practicalities of identifying poorly documented sites dating to the late nineteenth century. In recognizing Indigenous presence in the centuries after 1492, this volume counters continued patterns of unknowing in archaeology and offers new perspectives on decolonizing the field. These essays show how this approach can help expose silenced histories, modeling research practices that acknowledge Tribes as living entities with their own rights, interests, and epistemologies.

Medical Astrology: Galactic Code describes the fascinating discovery of the Galactic Code. As the genetic code composes proteins from nucleic acids, the Galactic Code forms the structures for the main biological systems from the energies of the constellations of the Zodiac. The Human systems form the Zodiac Ecliptic around each person similar to the one in the sky. This "Human Ecliptic" determines the major energies of the body and its biological systems. The Human Ecliptic determines the stages of the human development, the stages of the influence of the nervous system and the human temperaments. The cardinal cross shows the influence of the elements on the work of the body. The theory combines astrological, medical and psychological sciences and is a mind-expanding read.

In this tender but unblinking portrait of his tiny hometown, Richard B. Ulmer Jr. describes an enchanted boyhood amid the creeks and cornfields of Yorktown, Iowa, where his father was superintendent of a two-room Lutheran school. With shrewd economy, Ulmer depicts a whimsical place inhabited by Midwestern archetypes: laconic farmers with seed-cap tans; a mayor tasked with plinking rabid dogs with his .22; a leading citizen who serves as "postmaster, slaughterhouse proprietor, butcher, grocer, and possessor of the fire truck's keys." Ulmer and his five sisters enjoyed childhoods guided by a common-sense credo: "Don't get a big head." They roamed a wilting hamlet that seemed a wonderland, with its public croquet court, mysterious "shivaree" rituals outside the homes of newlyweds, and a concrete bandstand in the middle of main street-"a looming liability in another time and place," Ulmer writes. "But Iowans were so good-natured, and Yorktown had so few assets, that no one ever sued."
