  Cobalt - Cradle of the Demon...

  The world is desperate for cobalt. It drives the proliferation of digital and clean technologies. But this "demon metal" has a horrific present and a troubled history. 
   
   
   
  The modern search for cobalt has brought investors back to a small town in Northern Canada, a place called Cobalt. Like the demon metal, this town has a dark and turbulent history. 
   
   
   
  The tale of the early-twentieth-century mining rush at Cobalt has been told as a settle's adventure, but Indigenous people had already been trading in metals from the region for two thousand years. And the events that happened here—the theft of Indigenous lands, the exploitation of a multicultural workforce, and the destruction of the natural environment—established a template for resource extraction that has been exported around the world. 
   
    
   
  Charlie Angus reframes the complex and intersectional history of Cobalt within a broader international frame—from the conquistadores to the Western gold rush to the struggles in the Democratic Republic of Congo today. He demonstrates how Cobalt set Canada on its path to become the world's dominant mining superpower.

  Churches and the Crisis of...

  Congregations often seek to combat the crisis of decline by using innovation to produce new resources. But leading practical theologian Andrew Root shows that the church's crisis is not in the loss of resources; it's in the loss of life—and that life can only return when we remain open to God's encountering presence. 
   
   
   
  This new book, related to Root's critically acclaimed Ministry in a Secular Age project, addresses the practical form the church must take in a secular age. Root uses two stories to frame the book: one about a church whose building becomes a pub and the other about Karl Barth. Root argues that Barth should be understood as a pastor with a deep practical theology that can help church leaders today. 
   
   
   
  This book pushes the church to be a waiting community that recognizes that the only way for it to find life is to stop seeing the church as the star of its own story. Instead of resisting decline, congregations must remain open to divine action. Root offers a rich vision for the church's future that moves away from an obsession with relevance and resources and toward the living God.

  Optics - Principles and...

  Optics is the branch of physics that deals with the study of light and its interaction with matter. It encompasses a wide range of phenomena, including reflection, refraction, diffraction, and the formation of images. Light, as an electromagnetic wave, plays a central role in our everyday lives, enabling us to see the world around us and facilitating numerous technological advancements. The study of optics is essential not only for understanding the behavior of light but also for developing applications in fields such as medicine, telecommunications, photography, and astronomy. 
  The nature of light has been a subject of fascination and research for centuries. Early thinkers, such as ancient Greek philosophers, speculated about the properties of light and its role in vision. However, it was not until the work of scientists like Isaac Newton and Thomas Young in the 17th and 18th centuries that light began to be studied in a more rigorous and scientific manner. Newton’s particle theory of light and Young’s double-slit experiment, which demonstrated the wave nature of light, were crucial milestones in the development of optics. These contributions laid the groundwork for the modern understanding of light as an electromagnetic wave, described by Maxwell’s equations. 
  At the heart of optics is the study of how light behaves as it interacts with different materials. This behavior is governed by the fundamental principles of reflection, where light bounces off surfaces, and refraction, where light bends as it passes through different media. These principles are described by laws such as the Law of Reflection and Snell’s Law of Refraction. The interaction of light with materials also leads to phenomena such as dispersion, where different colors of light separate due to their varying wavelengths, and absorption, where light energy is transferred to the material, often converting to heat.

  Nineteen Reservoirs - On Their...

  Without the nineteen upstate reservoirs that supply its water, New York City as we know it would not exist today. 
   
   
   
  From 1907 to 1967, a network of reservoirs and aqueducts was built across more than one million acres in upstate New York, including Greene, Delaware, Sullivan, and Ulster Counties. This feat of engineering served to meet New York City's ever-increasing need for water, sustaining its inhabitants and cementing it as a center of industry. West of the Hudson, it meant that twenty-six villages, with their farms, forest lands, orchards, and quarries, were bought for a fraction of their value, demolished, and submerged, profoundly altering ecosystems in ways we will never fully appreciate. 
   
   
   
  This paradox of victory and loss is at the heart of Nineteen Reservoirs, Lucy Sante's meticulous account of how New York City secured its seemingly limitless fresh water supply, and why it cannot be taken for granted. In inimitable form, Sante plumbs the historical record to surface forgotten archives and images, bringing lost places back to life on the page. Her immaculately calibrated sensitivity honors both perspectives on New York City's reservoir system and helps us understand the full import of its creation.

  'I proudly wear my badge as a Covid-19 front-line hero. I believe I was meant to be where I am during these trying times.'
  Our nurses have witnessed the pandemic first hand, compassionately caring for patients amid war-like circumstances.
  The havoc caused by the pandemic highlighted existing fault lines in the South African health system, and nurses faced shortages of staff and vital life-saving equipment. Colleagues tested positive and died. Visitors were not allowed, so nurses had to be intermediaries between patients and desperate family trying to glean information on the phone. Despite these pressures, they remained at the forefront of the fight against the deadly virus.
  This book brings together deeply personal stories of caring for patients in wards and ICU, of feeling overwhelmed, and experiencing the fear of getting infected and passing Covid on to their families. There are also moving tales of personal growth and finding renewed purpose. In Our Own Words shows the extreme resilience of nurses – even in the face of adversity. And that at the core of a 'true' nurse remains the commitment to the patient.
  'A powerful and moving account from the coalface of the Covid-19 response – this is a must read!' – Salim Abdool Karim
