  Optics - Principles and...

  Optics is the branch of physics that deals with the study of light and its interaction with matter. It encompasses a wide range of phenomena, including reflection, refraction, diffraction, and the formation of images. Light, as an electromagnetic wave, plays a central role in our everyday lives, enabling us to see the world around us and facilitating numerous technological advancements. The study of optics is essential not only for understanding the behavior of light but also for developing applications in fields such as medicine, telecommunications, photography, and astronomy. 
  The nature of light has been a subject of fascination and research for centuries. Early thinkers, such as ancient Greek philosophers, speculated about the properties of light and its role in vision. However, it was not until the work of scientists like Isaac Newton and Thomas Young in the 17th and 18th centuries that light began to be studied in a more rigorous and scientific manner. Newton’s particle theory of light and Young’s double-slit experiment, which demonstrated the wave nature of light, were crucial milestones in the development of optics. These contributions laid the groundwork for the modern understanding of light as an electromagnetic wave, described by Maxwell’s equations. 
  At the heart of optics is the study of how light behaves as it interacts with different materials. This behavior is governed by the fundamental principles of reflection, where light bounces off surfaces, and refraction, where light bends as it passes through different media. These principles are described by laws such as the Law of Reflection and Snell’s Law of Refraction. The interaction of light with materials also leads to phenomena such as dispersion, where different colors of light separate due to their varying wavelengths, and absorption, where light energy is transferred to the material, often converting to heat.

  The Titanic. The Britannic. The Olympic. They are some of the most famous ships in history, but for the wrong reasons. 
   
   
   
  The Olympic Class liners were conceived as the largest, grandest ships ever to set sail. Of the three ships built, the first only lost the record for being the largest because she was beaten by the second, and they were both beaten by the third. The class was meant to secure the White Star Line's reputation as the greatest shipping company on earth. Instead, with the loss of both the Titanic and the Britannic in their first year of service, it guaranteed White Star's infamy. 
   
   
   
  This unique book tells the extraordinary story of these three extraordinary ships from the bottom up, starting with their conception and construction (and later their modification) and following their very different careers. Behind the technical details of these magnificent ships lies a tragic human story—not just of the lives lost aboard the Titanic and Britannic, but of the designers pushing the limits beyond what was actually possible, engineers unable to prepare for every twist of fate, and ship owners and crew who truly believed a ship could be unsinkable.

  An irresistibly moving, funny and urgent memoir about the reality of caring for your parents, when you can barely care for yourself.'Moving and real, as well as splutter-your-tea funny' – Miranda SawyerIt was the kind of phone call we all dread. Your elderly father has been admitted to hospital. Your mum is about to be left at home alone. The answer? Drop everything. Go. Help. The reality? Not so straightforward. Suddenly, you’re a kid again, stranded in the overheated house you grew up in. They need you 24/7, that much is obvious. And you want to help, of course you do. But soon your life starts to unravel almost as quickly as their health.In between bouts of washing, feeding, cooking and fighting there are days that test you, days where everything goes wrong and days where everyone, miraculously rises to the occasion. And in between all of that, you learn how to care. But this time with feeling.Irresistibly funny, unflinching and deeply moving, this is a love letter to family and friends, to carers and to anyone who has ever packed a small bag intent on staying for just a few days.

  Infinity of Worlds An - Cosmic...

  In the beginning was the Big Bang: an unimaginably hot fire almost fourteen billion years ago in which the first elements were forged. The physical theory of the hot nascent universe—the Big Bang—was one of the most consequential developments in twentieth-century science. And yet it leaves many questions unanswered: Why is the universe so big? Why is it so old? What is the origin of structure in the cosmos? In An Infinity of Worlds, physicist Will Kinney explains a more recent theory that may hold the answers to these questions and even explain the ultimate origins of the universe: cosmic inflation, before the primordial fire of the Big Bang. 
   
   
    
  Kinney argues that cosmic inflation is a transformational idea in cosmology, changing our picture of the basic structure of the cosmos and raising unavoidable questions about what we mean by a scientific theory. He explains that inflation is a remarkable unification of inner space and outer space, in which the physics of the very large (the cosmos) meets the physics of the very small (elementary particles and fields), closing in a full circle at the first moment of time. 
   
    
    
  Kinney considers the consequences of eternal cosmic inflation. Can we come to terms with the possibility that our entire observable universe is one of infinitely many, forever hidden from our view?

  Being human entails an astonishingly complex interplay of biology and culture, and while there are important differences between women and men, there is a lot more variation and overlap than we may realize. Sex Is a Spectrum offers a bold new paradigm for understanding the biology of sex, drawing on the latest science to explain why the binary view of the sexes is fundamentally flawed. 
   
   
   
  In this lively and provocative book, leading biological anthropologist Agustín Fuentes begins by tracing the origin and evolution of sex, describing the many ways in the animal kingdom of being female, male, or both. Turning to humans, he presents evidence from the fossil and archaeological record that attests to the diversity of our ancestors' sexual bonds, gender roles, and family and community structures, and shows how the same holds true in the lived experiences of people today. Fuentes tackles hot-button debates around sports and medicine, explaining why we can acknowledge that females and males are not the same while also embracing a biocultural reality where none of us fits neatly into only one of two categories. 
   
   
   
  Bringing clarity and reason to a contentious issue, Sex Is a Spectrum shares a scientist's perspective on why a binary view of sex and gender is not only misguided but harmful, and why there are multitudes of ways of being human.

  Nursing is more than just a profession; it is a calling that blends compassion, science, and clinical expertise to promote health and well-being. As one of the most trusted professions globally, nursing plays a critical role in the healthcare system, directly impacting patients' lives and outcomes. This chapter provides an overview of nursing careers, introducing the diverse roles within the field and the various paths one can take to become a nurse.  
  Nurses are at the heart of patient care, often serving as the bridge between patients and other healthcare professionals. They are involved in a wide range of activities, from administering medications and performing clinical procedures to providing emotional support and educating patients about their health conditions. Nurses work in various settings, including hospitals, clinics, nursing homes, community centers, schools, and even patients' homes, adapting their skills to meet the specific needs of each environment. 
  Nursing has evolved significantly over the years, transforming from a vocation focused on basic patient care to a profession that requires advanced education, specialized training, and critical thinking skills. The modern nurse is not only a caregiver but also a leader, researcher, advocate, and educator. This evolution has opened up new career opportunities within the field, allowing nurses to specialize in areas such as pediatrics, geriatrics, critical care, mental health, and public health, among others.
