  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.

  Audiology is the branch of science that focuses on the study of sound, hearing, and balance. It is a multifaceted field that encompasses the assessment, diagnosis, and treatment of various auditory and vestibular disorders. The role of audiologists is essential in identifying hearing impairments, providing interventions, and promoting overall ear health, which plays a vital part in communication and quality of life. 
  Sound, in its simplest form, is the vibration of molecules in the air that travel as waves to our ears. As one of the primary ways humans perceive the world around them, hearing is not only crucial for communication but also for safety, socialization, and enjoyment. Audiologists specialize in understanding these complex processes and the challenges that arise when they are impaired. Their work involves not only diagnosing hearing loss but also managing conditions related to balance and the inner ear, both of which are intricately linked. 
  The study of audiology dates back to the early 20th century, with significant advancements made throughout the decades in both technology and methodology. Today, audiology has grown into a highly specialized field that includes a range of services, from basic hearing tests to advanced procedures like cochlear implants and balance rehabilitation. Audiologists employ a variety of diagnostic tools, including audiometers, tympanometers, and specialized tests, to evaluate hearing and vestibular function. These assessments are critical in identifying the specific nature of auditory or balance problems, which can stem from a range of causes such as aging, genetics, illness, injury, or environmental factors.

  Four Dissertations - A Natural...

  David Hume

  David Hume (1711-1776) remains one of the most stimulating and entertaining writers in the English essay tradition. Though primarily known for long-form writings, he was adept at taking one subject and looking at it in a more concise but accessible manner. 
  Hume devoted his life to study – across a wide range of his personal interests, reflecting his background in philosophy, history, economics, and many other subjects. This can be clearly seen in Four Dissertations (1757) and the topics he chose to consider. 
   
  Of these, The Natural History of Religion is the most well-known and widely quoted. Hume’s views, shaped by empiricism and scepticism, enables him to offer a perspective unusual for his age, though naturally it is embedded in the prevailing view ‘The whole frame of nature bespeaks an intelligent author’. Nevertheless, this does not restrict his thinking as he examines the psychological and sociological factors that shape religious sentiment. 
   
  The other three Dissertations are no less fascinating. Fittingly, in Of The Passions, Hume delves into the complex realm of human emotions. Investigating the nature of desire, love, fear, and more, he presents a wide-ranging study of how passions influence our actions and shape our experiences. 
   
  Of Tragedy, explores the aesthetics of dramatic art. Hume looks into the power of tragedy to elicit a passionate response and provoke contemplation. He examines the mechanisms by which tragedies captivate audiences and evoke a range of sentiments, shedding light on the profound impact of art on human consciousness. 
   
  In Of the Standard of Taste, Hume takes the viewpoint of the beholder, rather than the object. Declaring ‘We are apt to call barbarous whatever departs widely from our own taste and apprehension,’ he proposes that two elements, sentiment and critical faculty form a major part in decisions on taste. For “Beauty is no quality in things themselves: It exists merely in the mind which contemplates them; and each mind perceives a different beauty.” But such a subjective view cannot deny a certain consensus on beauty, which leads Hume to examine the matter of aesthetics in the light of judgements of established critics. 
   
  This recording concludes with Hume’s two short autobiographies, written at different times in his life and with differing characteristics. The first, A Kind of Life (1734) is a letter written to a doctor and the second, My Own Life (1776) was written shortly before his death.

  World War II in 1941: The...

  At the beginning of 1941, it was unclear whether the Allies would be able to remain in the war for much longer. British Prime Minister Winston Churchill had already immortalized the men of the Royal Air Force with one of the West’s most famous war-time quotes, but the potential of a German invasion of Britain still loomed. With the comfort of hindsight, historians now suggest that the picture was actually more complex than that, but the Battle of Britain, fought throughout the summer and early autumn of 1940, was unquestionably epic in scope.  
  In the warm predawn darkness of June 22, 1941, 3 million men waited along a front hundreds of miles long, stretching from the Baltic coast of Poland to the Balkans. Ahead of them in the darkness lay the Soviet Union, its border guarded by millions of Red Army troops echeloned deep throughout the huge spaces of Russia. This massive gathering of Wehrmacht soldiers from Adolf Hitler's Third Reich and his allied states – notably Hungary and Romania – stood poised to carry out Operation Barbarossa, Hitler's surprise attack against the country of his putative ally, Soviet dictator Joseph Stalin. 
  All Americans are familiar with the “day that will live in infamy.” At 9:30 a.m. on Sunday, December 7, 1941, Pearl Harbor, the advanced base of the United States Navy’s Pacific Fleet, was ablaze. It had been smashed by aircraft launched by the carriers of the Imperial Japanese Navy. All eight battleships had been sunk or badly damaged, 350 aircraft had been knocked out, and over 2,000 Americans lay dead. Indelible images of the USS Arizona exploding and the USS Oklahoma capsizing and floating upside down have been ingrained in the American conscience ever since. In less than an hour and a half the Japanese had almost wiped out America’s entire naval presence in the Pacific.
