Writing about time travel is, today, a respectable business. It hasn’t always been so. After all, time travel, prima facie, appears to violate a fundamental law of nature; every effect has a cause, with the cause occurring before the effect. Time travel to the past, however, seems to allow, indeed to demand, backwards causation, with an effect (the time traveler emerging into the past as he exits from his time machine) occurring before its cause (the time traveler pushing the start button on his machine’s control panel to start his trip backward through time). Time Machine Tales includes new discussions of the advances by physicists and philosophers that have appeared since the publication of TIME MACHINES in 1999, examples of which are the chapters on time travel paradoxes.

The heat equation, a cornerstone of modern physics, demystifies such processes, painting a mathematical picture of the way heat diffuses through matter. Presenting the mathematics and history behind the heat equation, Hot Molecules, Cold Electrons tells the remarkable story of how this foundational idea brought about one of the greatest technological advancements of the modern era.  Paul Nahin vividly recounts the heat equation’s tremendous influence on society, showing how French mathematical physicist Joseph Fourier discovered, derived, and solved the equation in the early nineteenth century. Nahin then follows Scottish physicist William Thomson, whose further analysis of Fourier’s explorations led to the pioneering trans-Atlantic telegraph cable. This feat of engineering reduced the time it took to send a message across the ocean from weeks to minutes. Readers also learn that Thomson used Fourier’s solutions to calculate the age of the earth, and, in a bit of colorful lore, that writer Charles Dickens relied on the trans-Atlantic cable to save himself from a career-damaging scandal. The book’s mathematical and scientific explorations can be easily understood by anyone with a basic knowledge of high school calculus and physics, and MATLAB code is included to aid readers who would like to solve the heat equation themselves.  A testament to the intricate links between mathematics and physics, Hot Molecules, Cold Electrons offers a fascinating glimpse into the relationship between a formative equation and one of the most important developments in the history of human communication.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":51313321836817,"sku":"NGR9780691191720","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51313382097169,"sku":"CIN0691191727VG","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"GB \/ VERY_GOOD \/ INTERNAL","offer_id":51313383440657,"sku":"GOR012999310","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":51313384358161,"sku":"CIN0691191727G","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0691191727.jpg?v=1750881000"},{"product_id":"mathematical-radio-book-paul-j-nahin-9780691235332","title":"The Mathematical Radio","description":"How a modern radio works, told through mathematics, history, and selected puzzles  The modern radio is a wonder, and behind that magic is mathematics. In The Mathematical Radio, Paul Nahin explains how radios work, deploying mathematics and historical discussion, accompanied by a steady stream of intriguing puzzles for math buffs to ponder. Beginning with oscillators and circuits, then moving on to AM, FM, and single-sideband radio, Nahin focuses on the elegant mathematics underlying radio technology rather than the engineering. He explores and explains more than a century of key developments, placing them in historical and technological context.  Nahin, a prolific author of books on math for the general reader, describes in fascinating detail the mathematical underpinnings of a technology we use daily. He explains and solves, for example, Maxwell’s equations for the electromagnetic field. Readers need only a familarity with advanced high school–level math to follow Nahin’s mathematical discussions. Writing with the nonengineer in mind, Nahin examines topics including impulses in time and frequency, spectrum shifting at the transmitter, the superheterodyne, the physics of single-sideband radio, and FM sidebands. Chapters end with “challenge problems” and an appendix offers solutions, partial answers, and hints. Readers will come away with a new appreciation for the beauty of even the most useful mathematics.","brand":"WoB","offers":[{"title":"- \/ - \/ -","offer_id":51597708689681,"sku":"","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":51597708886289,"sku":"NGR9780691235332","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":52507117748497,"sku":"NIN9780691235332","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ LIKE_NEW \/ SBYB","offer_id":52880037413137,"sku":"CIN0691235333LN","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0691235333.jpg?v=1750912433"},{"product_id":"delicate-art-of-brute-force-book-paul-j-nahin-9780691267463","title":"The Delicate Art of Brute Force","description":"Using everyday computational power to tackle complex—and seemingly unsolvable—math problems  Confronted by a math problem of seemingly impenetrable difficulty, what can you do? In The Delicate Art of Brute Force, Paul Nahin shows how even if you can’t solve such a problem, you can still get an answer. The computational power of your own computer—the desktop in your home office, the laptop on your coffee table—can be deployed to overwhelm a problem’s complexity through a massive number-crunching assault. Nahin presents a series of apparently intractable math problems and shows the thought process that allows computational solution. Most of the problems are not abstract constructions but originate in the real world—one chapter is titled “How Wi-Fi Coverage and Anti-Submarine Warfare Are the Same.” For each one, Nahin compares computational and analytical approaches, demonstrating how well the computer solutions agree with theory. As a bonus, sometimes the computational solution is better, giving more insight or greater flexibility.  Along the way, Nahin traces the evolution of high-speed electronic computation, explaining that it upended the way analysts approach complex math problems. After the postwar debut of ENIAC (Electronic Numerical Integrator and Computer) and the ever more powerful electronic computers that came afterward, problems that were simply too difficult or messy for analytical treatment could be defeated by the application of pure brute force—the ability of computers to perform an enormous number of simple operations in just minutes. Today, we can harness that computational power from our couches. Accessible to anyone who’s mastered high school calculus, this engaging book gives both mathematicians and nonmathematicians plenty to think about.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":52152172904721,"sku":"NGR9780691267463","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ NEW \/ INGRAM","offer_id":53134414414097,"sku":"NIN9780691267463","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780691267463.jpg?v=1758276782"},{"product_id":"probability-integral-book-paul-j-nahin-9783031384189","title":"The Probability Integral","description":"This book tells the story of the probability integral, the approaches to analyzing it throughout history, and the many areas of science where it arises. The so-called probability integral, the integral over the real line of a Gaussian function, occurs ubiquitously in mathematics, physics, engineering and probability theory. Stubbornly resistant to the undergraduate toolkit for handling integrals, calculating its value and investigating its properties occupied such mathematical luminaries as De Moivre, Laplace, Poisson, and Liouville. This book introduces the probability integral, puts it into a historical context, and describes the different approaches throughout history to evaluate and analyze it. The author also takes entertaining diversions into areas of math, science, and engineering where the probability integral arises: as well as being indispensable to probability theory and statistics, it also shows up naturally in thermodynamics and signal processing. Designed to be accessible to anyone at the undergraduate level and above, this book will appeal to anyone interested in integration techniques, as well as historians of math, science, and statistics.","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52418555248913,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":52418555871505,"sku":"NGR9783031384189","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783031384189.jpg?v=1758929465"},{"product_id":"time-machines-book-paul-j-nahin-9780387952222","title":"Time Machines","description":"Here's a gem of a book.all peppered with delightful notes from science fiction films, novels, and comics.

That is, SF is the literature of ‘what-if’ scenarios. This book explores more than a dozen such possibilities, with each chapter ending with a fictional illustration of the theme of that chapter (time travel, topology, alternate worlds, computer intelligence tests for politicians, invisibility, and more). The fictional treatments ask — and sometimes answer — questions like:   ⦁ What might happen if you discovered how to induce nuclear fusion in room temperature water?   ⦁ Could a combat soldier, and an intelligent, lethal weapon, develop a deep emotional relationship?   ⦁ If an archeologist, using x-rays, discovered the lost casket of Jesus in an Egyptian museum, would he open it? If he did, what might he find? (This tale appeared in print two years before the release of Raiders of the Lost Ark.)   ⦁ What if you received a letter, addressed specifically to you, from a man who died decades before you were born?   ⦁ Could a little boy who tries to fix the family television set save Earth from an interstellar invasion?   ⦁ In 1971 ‘D. B. Cooper’ high-jacked a commercial airliner and then bailed-out (with a $200,000 ransom) into a snowstorm and vanished forever. Or did he?   ⦁ What might happen if you ate a four-dimensional doughnut?
