  Gravity is at once familiar and mysterious. It's the reason for the numbers on your bathroom scale, the intricate dance of the stars and planets, and the evolution and eventual fate of the universe. In Crush, James Riordon takes listeners on a tour of gravity from its vanishing insignificance on the microscopic scale to its crushing extreme inside black holes.From the moment we lift our heads as infants until the moment we lie down and ultimately surrender to its pull at the end of our lives, we labor under the burden of gravity. It has guided the shape and structure of our bodies over eons of evolution and sculpted the Earth as it cooled from a blob of molten rock. As Riordon explains, the stars couldn't shine without gravity holding them together. Even the atoms that make up you and everything around you were forged in stellar furnaces that gravity built. It took Einstein to realize that gravity is not, in fact, a force at all, but instead the curvature of space and time.A fascinating and memorable listen, Crush examines our personal relationships with gravity; explores gravity's role in making the universe uniquely hospitable for life; and even reveals how the mundane flow of water in your kitchen sink offers a glimpse into the secrets of black holes.

  In the rapidly urbanizing world of the 21st century, cities have emerged as the defining habitat for human existence—complex ecosystems where built environments, natural systems, social dynamics, and human health are inextricably intertwined. As urban populations continue to expand globally, the relationship between metropolitan environments and human wellbeing has become one of the most critical frontiers in our collective pursuit of sustainable, equitable development. This comprehensive exploration delves into the multifaceted domains of Urban Environmental Studies, Urban Health, and City Livability—examining how the physical, social, and ecological dimensions of urban spaces fundamentally shape population health outcomes, quality of life, and environmental sustainability. 
  The narrative of urban environmental health transcends traditional disciplinary boundaries; it encompasses the intricate connections between urban design, ecological systems, public health infrastructure, and social determinants that collectively define the healthfulness of city living. By examining the complex interplay between environmental exposures, built environment characteristics, healthcare access, and community resilience, this book illuminates how cities can function either as amplifiers of health inequities or as platforms for promoting wellbeing across diverse populations. Readers will journey through the multidimensional landscapes where urban health manifests—from the microscale of indoor air quality and neighborhood walkability to the macroscale of urban heat islands and metropolitan food systems—while exploring innovative approaches that cities worldwide are adopting to create more livable, healthy, and environmentally sustainable urban futures.

  Quantum Gravity - Theories about...

  Quantum gravity is a field of theoretical physics that aims to describe the gravitational force according to the principles of quantum mechanics. 
  General relativity, developed by Albert Einstein, describes gravity as the curvature of spacetime caused by mass and energy. It works extremely well at large scales, such as in predicting planetary orbits and the behavior of black holes. On the other hand, quantum mechanics deals with the fundamental behavior of particles at the smallest scales, such as atoms and subatomic particles. It incorporates principles like wave-particle duality, quantization, and uncertainty. 
  Despite their success, general relativity and quantum mechanics are fundamentally incompatible. General relativity treats gravity as a smooth, continuous field, while quantum mechanics relies on quantized fields and inherently probabilistic events. When attempting to describe situations where both quantum effects and strong gravitational effects are significant, such as in the vicinity of black holes or during the Big Bang, the theories conflict. Quantum gravity aims to unify these two frameworks. 
  Several approaches have been proposed to formulate a theory of quantum gravity. String theory proposes that fundamental particles are not point-like but instead one-dimensional "strings" that vibrate at different frequencies. This theory inherently includes gravity and attempts to unify all fundamental forces. Loop quantum gravity (LQG) focuses on quantizing spacetime itself, positing that spacetime has a discrete structure at the smallest scales and attempts to describe the quantum properties of spacetime directly, without relying on a background.

  Nuclear and Particle Physics - A...

  Subatomic physics is the branch of physics that studies the fundamental particles and forces that constitute the universe at the smallest scales. It explores the nature of matter and energy at the level of atomic nuclei and beyond, delving into the complex interactions that govern the behavior of elementary particles. The study of subatomic physics emerged from the broader field of nuclear physics, which initially focused on the structure and properties of atomic nuclei. Over time, discoveries of new particles and interactions led to the expansion of the field into what is now known as particle physics. 
  The foundation of subatomic physics was laid with the discovery of the electron by J.J. Thomson in 1897, which provided the first evidence that atoms were composed of smaller constituent particles. This was followed by the discovery of the proton by Ernest Rutherford in 1917 and the neutron by James Chadwick in 1932, establishing the basic structure of the atomic nucleus. The development of quantum mechanics in the early 20th century provided a theoretical framework for understanding the behavior of these particles, revealing that their properties could only be accurately described through probabilistic wave functions and discrete energy levels. 
  In the mid-20th century, the discovery of a wide variety of new particles, including mesons, baryons, and leptons, suggested that protons and neutrons themselves were composed of more fundamental constituents. This led to the development of the quark model by Murray Gell-Mann and George Zweig in 1964, which proposed that protons and neutrons are made up of combinations of quarks held together by the strong nuclear force, mediated by gluons. The quark model became a central component of the Standard Model of particle physics, which describes the known elementary particles and the fundamental forces—excluding gravity—that govern their interactions.
