  New York's Secret Subway - The...

  In the nineteenth century, Manhattan's streets were so choked with pedestrians, horses, vehicles, and vendors that a trip from City Hall to Central Park could take hours. Alfred Beach had the perfect solution: build a giant pneumatic tube underneath Broadway from the Battery to Harlem. Air pressure would shoot passengers up and down the island in clean, quiet carriages. But Beach was up against the operators of the horse-drawn streetcars and the politicians in their pay, most conspicuously William M. Tweed, the notorious "Boss" of Tammany Hall.New York's Secret Subway: The Underground Genius of Alfred Beach and the Origins of Mass Transit tells a classic story of good versus evil, pitting the mild-mannered Beach, a visionary inventor and entrepreneur, against the oafish tyrant Tweed, the exemplar of corruption in the Gilded Age. It also tells the story of one of the most astonishing feats of engineering in American history, the surreptitious creation of the nation's first operational subway. Unfortunately, political lethargy and greed would conspire to deny the city a subway for another thirty years. Yet Alfred Beach still proved conclusively the feasibility of underground railways in Manhattan, and paved the way for modern mass transportation systems. Although this true story took place more than a century ago, it will at times sound surprisingly familiar.

  Dogopolis - How Dogs and Humans...

  Dogopolis presents a surprising source for urban innovation in the history of three major cities: human-canine relationships. 
    
  Stroll through any American or European city today and you probably won’t get far before seeing a dog being taken for a walk. It’s expected that these domesticated animals can easily navigate sidewalks, streets, and other foundational elements of our built environment. But what if our cities were actually shaped in response to dogs more than we ever realized? 
   
  Chris Pearson’s Dogopolis boldly and convincingly asserts that human-canine relations were a crucial factor in the formation of modern urban living. Focusing on New York, London, and Paris from the early nineteenth century into the 1930s, Pearson shows that human reactions to dogs significantly remolded them and other contemporary western cities. It’s an unalterable fact that dogs—often filthy, bellicose, and sometimes off-putting—run away, spread rabies, defecate, and breed wherever they like, so as dogs became a more and more common in nineteenth-century middle-class life, cities had to respond to people’s fear of them and revulsion at their least desirable traits. The gradual integration of dogs into city life centered on disgust at dirt, fear of crime and vagrancy, and the promotion of humanitarian sentiments. On the other hand, dogs are some people’s most beloved animal companions, and human compassion and affection for pets and strays were equally powerful forces in shaping urban modernity. Dogopolis details the complex interrelations among emotions, sentiment, and the ways we manifest our feelings toward what we love—showing that together they can actually reshape society.

  Introduction to Quantum Field...

  Quantum Field Theory (QFT) is the framework that unifies quantum mechanics and special relativity, providing a theoretical foundation for describing fundamental particles and their interactions. Unlike quantum mechanics, which describes particles as wavefunctions evolving in time, QFT treats particles as excitations of underlying fields that pervade all of space. This shift in perspective is necessary to accommodate relativistic effects and to describe processes such as particle creation and annihilation, which are not possible in non-relativistic quantum mechanics. 
  The motivation for QFT arises from the limitations of single-particle quantum mechanics when applied to high-energy physics. In relativistic systems, particles can be created and destroyed in interactions, as seen in high-energy collisions and radioactive decays. Traditional quantum mechanics, which treats particles as fixed entities, cannot account for such processes. By formulating particles as field excitations, QFT allows for a consistent description of multi-particle interactions and naturally incorporates the principles of special relativity. 
  At its core, QFT extends the principles of classical field theory to quantum systems. Classical field theories, such as Maxwell’s electrodynamics, describe how physical quantities vary across space and time. In QFT, these fields are quantized, meaning that their excitations correspond to discrete particles. The simplest example is the Klein-Gordon field, which describes spin-zero particles like mesons. The quantization of this field leads to the interpretation of its solutions as particle states, obeying relativistic energy-momentum relations.
