  The Seventymile Kid tells the remarkable account of Harry Karstens, who was the actual—if unheralded—leader of the Hudson Stuck Expedition that was the first to summit Mount McKinley in Alaska. All but forgotten by history, a young Karstens arrived in the Yukon during the 1897 Gold Rush, gained fame as a dog musher hauling U.S. Mail in Alaska, and eventually became the first superintendent of Mount McKinley National Park (now known as Denali National Park and Preserve). Aided by Karstens's own journals, longtime Denali writer and photographer Tom Walker uncovered archival information about the Stuck climb, and reveals that the Stuck "triumph" was an expedition marred by significant conflict. Without Karstens's wilderness skills and Alaska-honed tenacity, it is quite possible Hudson Stuck would never have climbed anywhere near the summit of McKinley. Yet the two men had a falling out shortly after the climb and never spoke again. In this book, Walker attempts to set the record straight about the historic first ascent itself, as well as other pioneer attempts by Frederick Cook and Judge Wickersham. 
   
   
   
  Fans of Alaska literature, American history, and mountaineering lore will love this adventurous biography of the largerthan-life "sourdough" Karstens, in which Alaska—its wilderness, its iconic mountain, and its pioneer spirit—looms large.

  What the Bears Know - How I...

  In the late 1990s, the town of Mammoth Lakes, California, hired Steve Searles as a hunter to cull half its troublesome bear population. But as he began to prepare for the grim task, the bears soon won him over, and Searles realized there had to be a better way. He soon developed nonlethal tactics to control their behavior and overpopulation that heralded a landmark moment in the care and handling of the American black bear. But change was not without its challenges. To some, his success was dismissed due to his lack of formal academic training. Yet Searles never wavered in his commitment, and eventually became not just local folk hero but a nationally recognized expert. This high school dropout saved not just the bears, but, in many ways, his community. 
   
   
   
  In a tradition that runs from John Muir to Bear Grylls, Searles finds a fellowship with nature and a deeper meaning in the world of bears. Do bears understand things we don't? Are they dialed in to some greater natural force? Unlike us, bears waste little time on unreasonable fears. Bears are fully in the moment. They have an inner peace that seems to offset their power and strength. That may explain why no other animal on the planet is as revered as the bear. As Searles shares his remarkable knowledge and we become immersed in the ursine world, you'll never look at bears or nature the same way again.

  Computational Methods for...

  Computational physics is a crucial branch of modern physics that utilizes numerical techniques and algorithms to solve complex physical problems. With the increasing complexity of theoretical models and the limitations of analytical solutions, computational methods have become an indispensable tool for physicists. From simulating quantum systems to modeling astrophysical phenomena, computation allows researchers to explore scenarios that are otherwise impractical or impossible to study experimentally. 
  One of the primary motivations for using computational techniques in physics is the ability to handle problems involving nonlinear equations, chaotic systems, or large datasets. Many physical equations, such as the Navier-Stokes equations in fluid dynamics or Schrödinger’s equation in quantum mechanics, lack closed-form analytical solutions. In such cases, numerical methods provide approximate but highly accurate solutions. Computational techniques also play a crucial role in experimental physics, where data analysis and simulations help interpret results and refine theoretical models. 
  Historically, computational physics emerged as a distinct discipline in the mid-20th century, with the advent of digital computers. Early physicists used numerical methods for simple problems, such as solving ordinary differential equations, but as computing power increased, so did the scope of applications. Today, computational physics is integrated with other scientific disciplines, including materials science, climate modeling, and biophysics, demonstrating its wide-ranging impact.

  Dark Energy – Puzzles from the Cosmic Deep explores the most profound and unsolved mysteries of the universe. This 3-in-1 volume pulls you into the heart of modern astrophysics and cosmology, where scientists are wrestling with forces that defy all expectations. At the center of it all is dark energy — the invisible phenomenon that’s not only real but accelerating the expansion of the universe itself. 
  In The Dark Energy Puzzle, you’ll trace the history of its discovery, from unexpected observations of distant supernovae to the revolutionary idea that empty space may not be empty at all. You'll learn how this unknown force challenges Einstein’s theories and leaves physicists grasping for answers that lie beyond current scientific frameworks. 
  Dark Forces dives deeper into the nature of the unseen universe, examining how dark energy interacts with gravity, time, and the structure of space itself. Could there be hidden dimensions? Is dark energy connected to the quantum vacuum? This section explores the weird and wondrous possibilities at the intersection of general relativity and quantum mechanics. 
  Finally, Cosmic Paradoxes brings the biggest questions to the forefront. Why is the universe accelerating? Will it expand forever—or rip itself apart in a catastrophic end? How can something we can't see or directly measure dominate the fate of everything? These paradoxes don’t just challenge our understanding of space—they force us to rethink the foundations of reality. 
  Perfect for curious minds fascinated by astronomy, cosmology, and the frontiers of theoretical physics, this book offers a rich and readable journey through one of the greatest puzzles in modern science. As you peer into the deep cosmos, you’ll uncover not just answers, but bigger and stranger questions.
