  The Physics of Stars - Exploring...

  Stars are the fundamental building blocks of the universe, shaping the evolution of galaxies and influencing cosmic phenomena on vast scales. Understanding their physics requires a detailed study of the forces governing their formation, structure, and lifecycle. Stellar physics combines principles from thermodynamics, nuclear physics, and general relativity to explain the energy production, stability, and eventual fate of stars. Observations across the electromagnetic spectrum, from radio waves to gamma rays, provide insights into stellar composition, temperature, and behavior. 
  At the heart of stellar physics is the balance between gravitational collapse and outward pressure. Gravity continuously pulls the stellar material inward, while nuclear fusion generates energy that radiates outward, maintaining equilibrium. This delicate balance determines the longevity of a star, with more massive stars consuming their fuel rapidly, while lower-mass stars burn slowly over billions of years. The life cycle of a star is deeply connected to its initial mass, which dictates its energy output, structure, and eventual transformation into a white dwarf, neutron star, or black hole. 
  Observing stars has been a cornerstone of astronomy for centuries, but modern telescopes and spectroscopy have revolutionized our understanding. Spectroscopy allows scientists to analyze starlight and determine the elements present in a star’s atmosphere. By studying absorption and emission lines, astronomers can infer a star’s composition, temperature, and motion. Advances in observational technology, such as space-based telescopes and high-resolution imaging, provide detailed views of stellar phenomena, revealing dynamic processes such as stellar flares, mass ejections, and pulsations.

  The Next Supercontinent -...

  You've heard of Pangea, the single landmass that broke apart some 175 million years ago to give us our current continents, but what about its predecessors, Rodinia or Columbia? These "supercontinents" from Earth's past provide evidence that land repeatedly joins and separates. While scientists debate what that next supercontinent will look like—and what to name it—they all agree: one is coming. 
   
   
   
  In this engaging work, geophysicist Ross Mitchell invites listeners to remote (and sometimes treacherous) lands for evidence of past supercontinents, delves into the phenomena that will birth the next, and presents the case for the future supercontinent of Amasia, defined by the merging of North America and Asia. Introducing listeners to plate tectonic theory through fieldwork adventures and accessible scientific descriptions, Mitchell considers flows deep in the Earth's mantle to explain Amasia's future formation and shows how this developing theory can illuminate other planetary mysteries. He then poses the inevitable question: how can humanity survive the intervening 200 million years necessary to see Amasia? 
   
   
   
  An expert on the supercontinent cycle, Mitchell offers listeners a front-row seat to a slow-motion mystery and an ongoing scientific debate.

  A Universe of Earths - Our...

  Planet Earth has been a familiar concept for a mere fraction of recorded history. Until about the mid-1600s, most humans thought of Earth as immobile, likely either dim or simply invisible from the Moon or anywhere else in the heavens, and not (like the planets) participating in what Galileo called "the dance of the stars." A Universe of Earths retraces the exhilarating story of how all that changed, and how we came to perceive the Earth as a "wandering star."  It's a story that has vastly augmented and enriched our understanding of how Earth and its inhabitants fit into the big picture of the Cosmos.But almost as soon as humans started to grasp that Earth is a planet, many also began wondering if perhaps the other planets might be earths. This bold conjecture ignited the whole gripping history and literature of space travel, of extraterrestrials, of other worlds. And yet the thesis that the Universe is full of other worlds like Earth has from the start been fueled more by imagination than by scientific evidence. 
  A Universe of Earths offers a surprising alternative to that "other worlds" account, one that releases humans not only from the pre-Copernican view of Earth as low, lowly, dark, a cosmic sump, but also from the persistent modern aspersion of Earth as cosmically ordinary, "mediocre," "dethroned."

  Journal of a Black Queer Nurse

  In this searing, honest memoir, a Black queer emergency-room nurse works the front lines of care during COVID-19. 
   
   
   
  Britney Daniels is a Black, masculine-presenting, tattooed lesbian from a working-class background. For the last five years, she has been working as an emergency-room nurse. She began Journal of a Black Queer Nurse as a personal diary, a tool to heal from the day-to-day traumas of seeing too much and caring too much. 
   
   
   
  Hilarious, gut-wrenching, and infuriating by turns, these stories are told from the perspective of a deeply empathetic, no-nonsense young nurse, who highlights the way race, inequality, and a profit-driven healthcare system make the hospital a place where systemic racism is lived. 
   
   
   
  Whether it is giving one's own clothes to a homeless patient, sticking up for patients of color in the face of indifference from white doctors and nurses, or nursing one's own back pain accrued from transporting too many bodies, Journal of a Black Queer Nurse reveals the ways in which care is much more than treating a physical body and how the commitment to real care—care that involves listening to and understanding patients in a deeper sense—demands nurses, especially nurses of color, must also be warriors.
