  Infinite Darkness - How Dark...

  Dark matter is one of the most intriguing mysteries in modern science. Despite making up approximately 27% of the universe, it cannot be seen or detected directly using traditional instruments. The name "dark matter" itself stems from the fact that it does not emit, absorb, or reflect light, making it invisible to the electromagnetic spectrum. However, its existence is inferred from its gravitational effects on visible matter, such as galaxies, stars, and other celestial objects. Without dark matter, the motion of galaxies would not make sense, as they appear to be moving far too quickly for the amount of visible matter they contain. This unseen substance holds galaxies together and ensures the stability of the universe’s large-scale structure. 
  The story of dark matter begins in the 1930s with the work of Swiss astronomer Fritz Zwicky. While studying the Coma galaxy cluster, Zwicky found that the visible matter in the galaxies was not enough to account for the way the galaxies were moving. He proposed that there must be some form of unseen mass providing additional gravitational pull, which he called "dark matter." Although his hypothesis was met with skepticism, it laid the foundation for further research into this invisible force. 
  Over the following decades, scientists gathered more indirect evidence supporting the existence of dark matter. In the 1970s, astronomer Vera Rubin and her colleague Kent Ford observed the rotation of galaxies and found that stars on the outer edges were moving much faster than expected. Based on the laws of physics and the visible mass, these stars should have been moving more slowly and would have been flung out of their orbits. The only explanation for their high speed was the presence of a significant amount of unseen mass—dark matter.

  Fluid Dynamics - Principles and...

  Fluid dynamics is a branch of physics that deals with the behavior of fluids (liquids and gases) in motion. It is a fundamental subject in engineering, physics, and applied sciences, playing a crucial role in various industries, including aerospace, automotive, energy, and environmental studies. Understanding how fluids move and interact with their surroundings helps engineers and scientists design efficient systems, predict natural phenomena, and develop innovative technologies. 
  At its core, fluid dynamics is governed by a set of fundamental principles derived from classical mechanics and thermodynamics. These include the conservation of mass, momentum, and energy. The governing equations, such as the Navier-Stokes equations, describe the motion of fluids by relating forces, pressure, velocity, and viscosity. The study of fluid dynamics is essential for solving real-world problems, from designing aircraft wings and optimizing fuel injection systems to predicting weather patterns and ocean currents. 
  Fluids can exhibit different types of motion depending on external forces, constraints, and their physical properties. A key distinction in fluid dynamics is between laminar flow and turbulent flow. Laminar flow is characterized by smooth, orderly fluid layers, whereas turbulent flow is chaotic and involves complex mixing and vortices. The Reynolds number, a dimensionless quantity, helps determine whether a flow will be laminar or turbulent based on factors like velocity, viscosity, and characteristic length.

  Finding Meaning in Wine - A US...

  This book examines controversies in American wine culture and how those controversies intersect with and illuminate current academic and cultural debates about the environment and about interpretation. 
   
   
   
  With a specific focus on the United States of America, the methods that we use to discuss literature and other art are applied to wine-making and wine culture. The book explores the debates about how to evaluate wine and the problems inherent in numerical scoring as well as evaluative tasting notes, whether winemakers can be artists, the discourse in wine culture involving natural wine and biodynamic farming, as well as how people judge what makes a wine great. These interpretative commitments illuminate an underlying metaphysics and allegiance to a culture of reason or feeling. The discussions engage with a broad range of writers and thinkers, such as Roland Barthes, Susan Sontag, Louis Menand, Michael Pollan, Greg Garrard, John Guillory, Amitov Ghosh, Pierre Bourdieu, and Barbara Herrnstein-Smith. The book draws upon not only a number of texts produced by wine critics, wine writers, literary critics, and theorists but also extensive interviews with wine writers and multiple California winemakers. These interviews contribute to a unique reflection on wine and meaning.

  An acclaimed science writer tells the story of cosmic projectiles that may be on a collision course with our Earth. 
   
   
   
  The impact of an asteroid led to the extinction of the dinosaurs. Could another giant cosmic missile soon be heading our way? In Target Earth, acclaimed Dutch astronomy writer Govert Schilling provides a full account of what we know, and need to know, about all the extraterrestrial matter constantly bombarding our planet—from microscopic dust particles and space debris to massive meteorites, comets, and asteroids. 
   
   
   
  Drawing upon the latest scientific discoveries, Schilling explores virtually every aspect of cosmic impacts—from small meteorites to devastating collisions, from the craters that marked our planet's surface to the impacts that left their mark on other celestial bodies, and from searches for near-miss lumps of rock to ways of protecting humanity from an assault from the cosmos. Along the way, he considers near misses in the past and the possibility of others in the future and ponders the positive side of these visitations from space: If our planet had not been the target of cosmic rubble from its very formation, life on Earth would likely never have gotten started.
