In Search Of Schrodinger's Cat: Updated Edition

Product Information

I looked behind me. A tabby was sitting, contentedly washing herself. "Hey! Where did you come from?" I asked. Schrodinger? I don't think I have met him. Does he live hereabouts?" I knew I had made a mistake the moment the question left my lips, because the cat's face darkened like thunder. What is the crossover point between undetectable and detectable, blurry and certain? When does quantum behavior disappear in favor of the everyday, macroscopic reality we're used to? Can we "chain together" reality so tiny behaviors determine larger ones? That's the direct question Schrödinger's Cat raises. Because it's absurd for a macroscopic object to be "blurred" (right?), the subatomic particle can't truly be blurred

Kuantum Kuramının güzel bir tarihi verilmiş kitapta. Üstelik bu tarihin her noktasındaki zorlukları, anlaşılmazlıkları, sorunları irdeleyerek ilerliyor, bu da kavramsal olgunluğu artırıyor. Kitap sonlara doğru iyice anlaşılmaz bir hal alıyor olsa da (ki bu konuların çok ağırlaşmasından kaynaklanıyor) genelde gayet güzel bir anlatımı var.It was, however, the final third that made me sit up, and read & re-read things, only to understand them. That part dealt with actual state of quantum theory, and needs considerable conceptual clarity, which is not so easy to muster at my stage. Philosophically, the issue reminds me of how we think about infinitely small quantities. Do infinitesimals exist? I was a bit uneasy. Needless to say, talking cats appearing out of nowhere and speaking in riddles was not usual in my daily routine. I started eyeing my Stephen King collection uneasily. "Who are you?" I asked.

Learning Gotcha: How We Misunderstood Schrödinger’s Cat Learning Gotcha: How We Misunderstood Schrödinger’s Cat

In 1968, Gribbin worked as one of Fred Hoyle's research students at the Institute of Theoretical Astronomy, and wrote a number of stories for New Scientist about the Institute's research and what were eventually discovered to be pulsars. La prosa del libro es impecable. La capacidad de John Gribbin de despertar la curiosidad y al mismo tiempo ser un buen crítico de la manera como los físicos hemos divulgado o entendemos la teoría cuántica es genial, especialmente al hablar de un tema de tanto interés. My companion looked pained. "I am much better than that grinning idiot from a stupid children's book, I'll have you know."I think this book is meant for laypeople, you don't need to understand any equations, but even for an expert, I think having the history laid out like this, and told in such a personable voice, must be interesting and helpful.

Well, it wasn't as good as I remember it. Maybe it was the passage of time and the advancement of science, maybe it was my own further studies in the field, maybe it was own growth and change in preferences, or maybe I just things didn't notice the first time. Don't get me wrong; it's still good, and I don't regret having read through it, but Gribbin is certainly not the best writer out there on these subjects. I would recommend Brian Greene, but he always wants to throw a plug in for the wonders of string theory and how it will solve EVERY SCIENTIFIC PROBLEM EVER; IT WILL EVEN CURE CANCER AND OBESITY!!!! Even so, Greene's description of the basic science is unparalleled. If you want an introduction on these matters read the opening two-thirds of either of his books (The Elegant Universe or The Fabric of the Cosmos).No: There's no such things as "infinitely small" things -- things are there, or not there. But they may be too small for you to detect. Analogy: Just because a camera is out of focus doesn't mean things in the world are actually blurry When you decide to open the box the world instantly splits into two with a dead cat in one and a purring and very much alive cat in another. The world you observe will make the result for you. You mean you don't know Schrodinger?" She hissed. "You ignoramus! He practically defined quantum theory. Oh, where do such fools like you come from?"

Si bien mucha agua ha pasado por el río de la física contemporánea desde el tiempo en el que el texto fue escrito (finales de los 80) los temas y las discusiones tienen una actualidad pasmosa que demuestra lo poco que realmente hemos avanzado en la comprensión de la teoría cuántica. Naturalmente la teoría cuántica moderna ha evolucionado, especialmente en las técnicas para su aplicación, en los sistemas a los que se aplica y en su poderoso rol en la tecnología, pero los problemas de fondo, las preguntas de fondo de las que se ocupa este librito siguen teniendo todavía mucha actualidad. this book explains generally the perplexing, mind-boggling, paradoxical principles of quantum physics while relating the history of discoveries leading up to and through it, including the discovery of the X-Ray.Oh! How cruel!" I felt that this Schrodinger guy must be a bounder of the first water, famous scientist or not. "He must be reported to the SPCA!" Overall, probably not unexpectedly, it changes your perception of a huge variety of reality aspects. The most striking for me was thought about the history: "In this delayed choice experiment something we do now has an irretrievable influence on what we can say about the past. History at least for one photon depends upon how we choose to make a measurement… Philosophers have long pondered the fact that history has no meaning - the past has no existence - except in the way it is recorded in the present." I think it has become even more relevant in our media savvy days when wars are played and won more on screen than at the actual battles fields. It feels surreal to find the natural phenomenon facilitating such an interpretation of the social reality. In 1984, Gribbin published In Search of Schrodinger's Cat: Quantum Physics and Reality, the book that he is best known for, which continues to sell well 28 years after publication. It has been described as among the best of the first wave of physics popularisations preceding Stephen Hawking's multi-million-selling A Brief History of Time. Gribbin's book has been cited as an example of how to revive an interest in the study of mathematics.
