Engineering Physics

المادَّة هي المكوِّن الأساسي للكون. ونحن نعرف الذرَّة جيداً وأنها جُسيم شديد الصِّغر لدرجة أن شعرة الإنسان الرفيعة قد تتَّسع لمليون ذرَّة. إلا أن المادَّة بحرٌ أوسع من هذا بكثير، وفَـهْـم طبيعتها عملية دؤوبة لا تنتهي. يستكشف «جيف كوتريل» خبايا جميع أشكال المادَّة، بدايةً من أشكالها المألوفة مثل المواد الصلبة والسائلة والغازيَّـة، وحتى البلازما والأشكال غير المألوفة، مثل المادَّة الكميَّـة والمادَّة المضادَّة. يستعرض كوتريل كذلك نشأة المادَّة في الانفجار العظيم، فيتحدَّث عن تكوين الذرَّة والطاقة والكتلة والأشكال الغامضة للمـادَّة المظلمة والطاقة المظلمة، فيتضح لنا أننا ما زلنا لا نعلم الكثير عن المادَّة التي يتكوَّن منها عالمنا.

What is time? What does it mean for time to pass? Is it possible to travel in time? What is the difference between the past and future? Until the work of Newton, these questions were purely topics of philosophical speculation. Since then we've learned a great deal about time, and its study has moved from a subject of philosophical reflection to instead became part of the subject matter of physics.

In a clear and engaging way, this book shows how the principle of emptiness, the philosophic heart of Tibetan Buddhism, connects intimately to quantum nonlocality and other foundational features of quantum mechanics. Detailed connections between emptiness, modern relativity, and the nature of time are also explored. For Tibetan Buddhists, the profound interconnectedness implied by emptiness demands the practice of universal compassion.

Throughout history, arguments for and against the existence of God have been largely confined to philosophy and theology, while science has sat on the sidelines. Despite the fact that science has revolutionized every aspect of human life and greatly clarified our understanding of the world, somehow the notion has arisen that it has nothing to say about the possibility of a supreme being, which much of humanity worships as the source of all reality.

The latest developments in physics have the potential to radically revise our understanding of the world: its makeup, its evolution, and the fundamental forces that drive its operation. Knocking on Heaven's Door is an exhilarating and accessible overview of these developments and an impassioned argument for the significance of science. There could be no better guide than Lisa Randall.

Quantum theory is the most revolutionary discovery in physics since Newton. This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed.

What are we made up of? What holds material bodies together? Is there a difference between terrestrial matter and celestial matter? When Democritus stated that we are made up of atoms, few people believed him. Not until Galileo and Newton in the seventeenth century did people take the idea seriously, and it was another four hundred years before we could reconstruct the elementary components of matter.

From the simulation hypothesis to parallel universes, "Exploring Simulated Worlds & Parallel Realities" transforms complex theories into fascinating, accessible insights that anyone can understand. Using clear examples and engaging thought experiments, these guides break down revolutionary concepts about the nature of reality itself.

The Big Bang is all but dead, and we do not yet know what will replace it. Our universe's "beginning" is at an end. What does this have to do with us here on Earth? Our lives are about to be dramatically shaken again - as altered as they were with the invention of the clock, the steam engine, the railroad, the radio and the Internet.

In 1695, Isaac Newton already renowned as the greatest mind of his agemade a surprising career change. He left quiet Cambridge, where he had lived for 30 years and made his earth-shattering discoveries, and moved to London to take up the post of Warden of His Majestys Mint. Newton was preceded to the city by a genius of another kind, the budding criminal William Chaloner.

Have you ever wondered why onions make us cry? Do you believe bananas contain more calories as they ripen and get sweeter? This sequel to the best-selling What Einstein Told His Cook continues Robert L. Wolke's investigations into the science behind our foods.

The second half of the 20th century witnessed a scientific gold rush as physicists raced to chart the inner workings of the atom. The stakes were high, the questions were big, and there were Nobel Prizes and everlasting glory to be won. Many mysteries of the atom came unraveled, but one remained intractable-what Frank Close calls the "Infinity Puzzle."

From the contours of coastlines to the outlines of clouds, and the branching of trees, fractal shapes can be found everywhere in nature. In this Very Short Introduction, Kenneth Falconer explains the basic concepts of fractal geometry, which produced a revolution in our mathematical understanding of patterns in the 20th century, and explores the wide range of applications in science, and in aspects of economics.

Force explores how humans interact with the material world in the course of their everyday activities. Celebrated author Henry Petroski draws from a variety of disciplines to make the case that force—represented especially by our sense of touch—is a unifying principle that pervades our lives. In the wake of a prolonged global pandemic that increasingly cautioned us about contact with the physical world, Petroski offers a new perspective on the importance of the sensation and power of touch.

This bundle of six books includes works covering such varied topics as astrophysics and speculation on matters such as UFOs and time travel.

Stephen W. Hawking's Cambridge lectures, exploring the most complex theories of physics, both past and present, remain the most important scientific theories known of time, space, and the nature of the cosmos. This 30th Anniversary remastered edition of The Cambridge Lectures offers listeners a unique opportunity to hear the full series of seven famed lectures exactly as Professor Hawking presented them during his tenure as Lucasian Professor of Mathematics at Cambridge University.

Victorian era steam engines and particle physics may seem worlds apart, yet a new branch of science, quantum thermodynamics, reenvisions the scientific underpinnings of the Industrial Revolution through the lens of today's roaring quantum information revolution. In her exciting new book, Harvard physicist Dr. Nicole Yunger Halpern introduces these concepts with what she calls "quantum steampunk," after the fantastical genre. Quantum Steampunk explores the field's aesthetic, shares its whimsy, and gazes into the potential of a quantum future.

Viajes en el tiempo, agujeros negros, motores de antimateria, aceleración del universo...La física moderna suena a película, pero es ciencia, de la de verdad verdadera, la que nos cuenta una historia fascinante de descubrimientos y sueños cumplidos, de luchas y disputas, y de pasión por comprender la naturaleza. Este divertido audio libro te ayudará a entender de una vez por todas lo que nos rodea, desde lo más pequeño a lo más grande, y a saber que El bosón de Higgs no te va a hacer la cama, ¡ni aunque le insistas!

What keeps objects from floating out of your hand? What if your feet drifted away from the ground? What stops everything from floating into space? Gravity. Author Jason Chin takes this complex subject and makes it brilliantly accessible to young listeners in this innovative book. His expansive but simple narrative does justice to the subject at hand, looking at the concept of gravity in a whole new way. From the redwoods to the oceans to a small island, he now takes us to outer space in this thoroughly researched, exceptional addition to his body of children's nonfiction.

Roberts' model, called quantum space theory, has been praised for how it offers an intuitively accessible picture of 11 dimensions and for powerfully extending the insight of general relativity, eloquently translating the four forces into unique kinds of geometric distortions while offering us access to the underlying deterministic dynamics that give rise to quantum mechanics. That remarkably simple picture explains the mysteries of modern physics in a way that's fully commensurate with Einstein's Intuition.
