  How do you apply game theory to select who should be on your Christmas shopping list? What equations should you use to decorate the Christmas tree? Will calculations show Santa is getting steadily thinner—shimmying up and down chimneys for a whole night—or fatter—as he munches on cookies and milk in billions of houses across the world?In The Indisputable Existence of Santa Claus, distinguished mathematicians Hannah Fry and Thomas Oléron Evans demonstrate, with eminent clarity, how applied mathematics are so thoroughly interwoven throughout our everyday lives by explaining mathematical concepts through one very merry motif: Christmas. In their quest to provide mathematical proof for the existence of Santa, the authors take listeners on a festive journey through a traditional holiday season, wherein every activity, from wrapping presents to playing board games to cooking the perfect turkey, is painstakingly and hilariously analyzed. Because who hasn't always wondered how to set up a mathematically perfect Secret Santa?Lighthearted and diverting with Christmasy equations, Markov chains, and matrices, The Indisputable Existence of Santa Claus brightens up the bleak midwinter with a stockingful of mathematical marvels.

  Squirrels are a common sight, seemingly everywhere in wild and urban nature. But squirrels are more than amusing backyard entertainers, and few of us know much about them or fully appreciate their role in keeping the environment healthy. As stress on the natural world intensifies, should we be paying more attention to the plight of squirrels?In Squirrel, Nancy Castaldo shines new light on this familiar backyard mammal, exploring their staggering diversity and the many surprising ways they shape our world, our communities, and our cultures. Each chapter explores an aspect of squirrels and their close and sometimes fraught association with humans: their importance to myriad ecosystems through sophisticated food-caching strategies; their introduction to nineteenth-century urban parks as adorable ambassadors for nature; their complicated global status as both invasive and endangered; their role as celebrated cultural icons and social media memes; and ultimately, why we must prevent population declines and protect their well-being while we can. Like other wildlife species, squirrels are increasingly stressed by climate change, and their speculative fate may foreshadow our own. The book includes a detailed bibliography, an exhaustive list of squirrel species and their status, and tips for coexisting peaceably with squirrels in our yards and neighborhoods.

  Egyptian Military Leaders -...

  The military strength of ancient Egypt was a defining factor in its ability to expand and sustain one of the most enduring civilizations in history. From its early beginnings, Egypt developed a structured and disciplined military that evolved to meet the challenges posed by both internal conflicts and foreign threats. The foundation of this power lay in the organization of its armed forces, the strategic leadership of its rulers, and the continual advancement of its weaponry and tactics. 
  In the early periods, Egypt's military was primarily a defensive force, focused on protecting the fertile Nile Valley from nomadic raiders. The unification of Upper and Lower Egypt under Narmer marked a crucial turning point, as military conquest became a tool for political consolidation. The pharaohs not only ruled as divine monarchs but also acted as supreme military commanders, leading their armies into battle and overseeing large-scale campaigns. This dual role reinforced their authority and ensured that military success translated into political stability. 
  One of the key factors in Egypt’s military rise was its ability to adapt to new technologies and strategies. During the Second Intermediate Period, Egypt faced the Hyksos, a foreign power that introduced advanced chariot warfare and superior composite bows. Instead of being permanently subdued, the Egyptians learned from their enemies, incorporating these innovations into their own forces. This adaptation played a crucial role in the expulsion of the Hyksos and the rise of the New Kingdom, during which Egypt became an empire with far-reaching influence.

  Brilliant, witty, perceptive essays about fly-fishing, the natural world, and life in general by the acknowledged master of fishing writers. 
   
   
   
  "In the world of fishing there are magic phrases that are guaranteed to summon the demon. Among them are: 'remote trout lake,' 'fish up to thirteen pounds,' 'the place the guides fish on their days off,'" writes John Gierach in this wonderful collection of thirteen essays inspired by a fishing trip to Rat Lake, a remote body of water in Montana. Once again John Gierach does what he does best—explain the peculiarities of the fishing life in a way that will amuse novices and seasoned fly fishers alike. The View from Rat Lake deftly examines man in nature and nature in man, the pleasures of fishing the high country, and the high and low comedy that occasionally overcomes even the best-planned fishing trip.
