In this book, William Cook takes readers on a mathematical excursion, picking up the salesman's trail in the 1800s when Irish mathematician W. R. Hamilton first defined the problem, and venturing to the furthest limits of today's state-of-the-art attempts to solve it. He also explores its many important applications, from genome sequencing and designing computer processors to arranging music and hunting for planets.In Pursuit of the Traveling Salesman travels to the very threshold of our understanding about the nature of complexity, and challenges you yourself to discover the solution to this captivating mathematical problem.

    His investigations shed light on what we can ultimately know about the universe and the very nature of life. In an infectious and enthusiastic narrative, Chaitin delineates the specific intellectual and intuitive steps he took toward the discovery. He takes us to the very frontiers of scientific thinking, and helps us to appreciate the art—and the sheer beauty—in the science of math.

    The main message i absorbed from it was a set of conditions required for success in mathematics: talent, yes; single-mindedness, almost as obvious; sense of humour, essential when the going gets tough; and love, yes that is the right word - you must love mathematics, and that means all the ingredients, passion, pain and loyalty." The Mathematical Gazette#1"The book is written in a very personal, but plain and honest way, result of reflected experience and mature self-assessment of a wise man. It avoids palliation as well as exaggerated modesty.- It should be a document for history and sociology of science." (R. Fischer) Zentralblatt für Mathematik#2

    The work is predicated on the idea that studying mathematics can generate the same enthusiasm as playing a team sport - without necessarily being competitive.

    Since its foundation in 1919, Leeds United Football Club has seen more ups and downs than most, rising to global fame through an inimitable and uncompromising style in the 70s, clinching the last Division One title of the pre-Sky Sports era in 1992, before becoming the epitome of financial mismanagement at the start of the 21st century. Despite this demise, United remains one of the best supported – and most divisive – clubs in football, with supporters’ clubs dotted across the globe. In 100 Years of Leeds United, Chapman delves deep into the archives to discover the lesser-known episodes, providing fresh context to the folkloric tales that have shaped the club we know today, painting the definitive picture of the West Yorkshire giants.

    If you like fun, adventure, and interesting tech, you’ll be sure to love something within this collection. Comprising three full length novels, and two novellas, these stories will keep you entertained for many hours. Warning: Readers might not want to come back to the real world after adventuring through these stories. Hollow Space: Venture Forced to hyperjump during a brutal ambush, Sara Lorelle, navigator of the the last human colony ship, discovers they’ve jumped to somewhere that shouldn’t exist. Trapped inside a pocket universe known only as Hollow Space, where technology inexplicably fails, Sara and her crew have to face the lethal politics of their only destination: Haven—a decrepit space station, home to hostile aliens and rival factions that soon sees the Venture crew up to their necks in trouble. With their only hope placed in Tairon Cauder, a reckless scoundrel, they will battle impossible species, confront their fears, and uncover ancient and terrible secrets. In a place where those who shoot first live the longest, the Venture crew will have to push their limits if they are to save themselves and the human race from extinction. Hollow Space: Shadowkill Kina wants to be an assassin—to join the mysterious Wraiths and secure her future on the space station of Haven. A place where it’s kill or be killed and career options are limited. But Haven is not your granddad’s space station. It’s rotten to the core and every scumbag is out for one thing only: themselves. With just her two daggers for protection, Kina is thrown into the darkness to confront a pack of bounty hunters eager to end her ambitions—and life. Code Breakers: Alpha In a post-apocalyptic future, humanity survives within a single domed city run by a shadowy benefactor known only as The Family. Each week the death lottery claims more lives and Gerry Cardle, head of the lottery, inexplicably finds himself the next on the list. Something's wrong with the system. A deadly artificial intelligence has breached security. Gerry has just 7 days to live. Forced off the grid, Gerry has to do the unthinkable: willingly leave the city. What he finds in the abandoned lands will shatter his perception of what it means to be human. Everything he had been told before was a lie. Code Breakers: Beta The fanatical Red Widows sweep destruction across the abandoned lands. Their aggression threatens to destroy the city Gerry had risked his life to save. Petal, the woman Gerry has come to love is dying. The despotic cabal, The Family, demand he brings her to them, but she's missing, running from the Widows, searching for the truth of her origins before it's too late. When their paths cross, Petal and Gerry will hold the fate of humankind in their hands—if they can survive the malevolent digital entity that stalks them from the shadows. The Daedalus Code When agents Phaedra and Aegeus of New Crete's Intelligent Data Enforcement Agency are tasked to find five missing Artificial Intelligence students, their single lead takes them to a notorious hacker known as 'The Cretian.' With his help, they uncover a terrible truth: Ariadne, one of the students, is involved with a rogue AI program called The Daedalus Project. The AI is out of control, people are going missing, and a great swathe of the world’s data is being secured within its digital labyrinth.

    Offering time-tested problems, conceptual and visual pedagogy, and a state-of-the-art media package, this 11th edition looks to the future of university physics, in terms of both content and approach.

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    Who invented zero? Why are there 60 seconds in a minute? Can a butterfly's wings really cause a storm on the far side of the world? In 50 concise essays, Professor Tony Crilly explains the mathematical concepts that allow use to understand and shape the world around us.

     This top-selling, theorem-proof text presents a careful treatment of the principal topics of linear algebra, and illustrates the power of the subject through a variety of applications. It emphasizes the symbiotic relationship between linear transformations and matrices, but states theorems in the more general infinite-dimensional case where appropriate.

    This book is very useful for all Students

    Hermann Weyl explores the concept of symmetry beginning with the idea that it represents a harmony of proportions, and gradually departs to examine its more abstract varieties and manifestations--as bilateral, translatory, rotational, ornamental, and crystallographic. Weyl investigates the general abstract mathematical idea underlying all these special forms, using a wealth of illustrations as support. Symmetry is a work of seminal relevance that explores the great variety of applications and importance of symmetry.
