This fully revised edition of a bestseller takes an approach which is grounded in physics with a logical flow of chapters leading the reader from basic ideas of the expansion described by the Friedman equations to some of the more advanced ideas about the early universe. It also incorporates up-to-date results from the Planck mission, which imaged the anisotropies of the Cosmic Microwave Background radiation over the whole sky. The Advanced Topic sections present subjects with more detailed mathematical approaches to give greater depth to discussions. Student problems with hints for solving them and numerical answers are embedded in the chapters to facilitate the reader’s understanding and learning.
Cosmology is now part of the core in many degree programs. This current, clear and concise introductory text is relevant to a wide range of astronomy programs worldwide and is essential reading for undergraduates and Masters students, as well as anyone starting research in cosmology. Supplementary material, including full-colour images, updates and links for students and instructors, is available on the author’s website: http://www.roe.ac.uk/~arl/.
The book continues to make the ideas and theories of modern physics easily understood by anyone, from researchers to students to general science enthusiasts. Taking you on a journey through space and time, author Jim Al-Khalili covers some of the most fascinating topics in physics today, including:
Black holes Space warps The Big Bang Time travel Wormholes Parallel universes
Professor Al-Khalili explains often complex scientific concepts in simple, nontechnical terms and imparts an appreciation of the cosmos, helping you see how time traveling may not be so far-fetched after all.
Quantum Reality: Theory and Philosophy cuts through much of the confusion to provide readers with an exploration of quantum theory that is as authoritatively comprehensive as it is intriguingly comprehensible. Requiring no more than school level physics and mathematics background, this volume requires only an interest in understanding how quantum theory came to be and the myriad ways it both explains how our universe functions and extends the reach of human knowledge.
Written by well-known physics author and teacher Dr. Jonathan Allday, this highly engaging work:
Presents a thorough grounding in the theoretical machinery of quantum physics
Offers a whistle-stop tour through the early part of the 20th century when the founding fathers of quantum theory forever altered the frontiers of human thought
Provides an example-filled interpretation of the theory, its applications, and its pinnacle in quantum field theory (QFT), so crucial in shaping ideas about the nature of reality
Separates fact from speculation regarding quantum physics’ ability to provide a starting point for philosophical queries into ultimate understanding and the limits of science
The world beneath the one that we experience with our senses is profoundly mysterious, and while we may never completely unravel that mystery, quantum theory allows us to come closer than ever to understanding where the science leaves off and the mystery begins. Quantum Reality: Theory and Philosophy makes that understanding accessible to anyone possessing a quest for knowledge and a sense of awe.
“Close is a lucid, reliable, and enthusiastic guide to the strange and wonderful microcosmic world that dwells deep within reality”
— Frank Wilczek, Herman Feshbach Professor of Physics, MIT, 2004 Nobel Prize in Physics
NEW Material Explains the principles behind the Hadron Collider as well as the potential it presents Considers the recent development of the Electroweak Theory as a law of nature Explores the mysteries uncovered and the ones that may be in store with regard to top and bottom quarks
Keeping still-pertinent contents from the original volume that caught the world’s attention in 1983, this fresh edition of the Cosmic Onion includes extensive new material to reflect new views of the universe. Providing explanations that explore the foundations of 21st Century science and future directions, this work offers ready access and unique perspectives to more typical topics such as the forces of nature, atoms, the nucleus, and nuclear particles.
It also travels down paths that only a true pioneer and educator can venture, such as a discussion of what Professor Close refers to as the Eightfold Way including the findings, surprises, and new questions emerging from the latest work with accelerators.
