In Search Of Schrodinger's Cat: Updated Edition

Product Information

It's unapologetically forthcoming, and NEVER tries to dumb down things in an effort towards becoming more "accommodating" and "plebian", which are the more euphemistic expressions for undervaluing the readers. No leía este libro desde que tenía unos 16 o 17 años. En aquel entonces comenzaba a enamorarme algo de la física y este libro definitivamente hizo parte del proceso. Hoy quiero que otros se enamoren del tema y quería saber que podía aprender del libro para mi propio ejercicio de divulgación. 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. In 2006, Gribbin took part in a BBC radio 4 broadcast as an "expert witness". Presenter Matthew Parris discussed with Professor Kathy Sykes and Gribbin whether Einstein "really was a 'crazy genius' ". Again, I don't claim to know anything about quantum mechanics. This about reading the source text and recognizing that the Schrödinger's Cat was used as a reductio ad absurdum, and is not what Schrödinger believed.

Having just wrapped the book up, my memory with innumerable sieves(I have forgotten the number) is nagging me to jot down my gleanings from this one. 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?" The book does show its age at parts but his amazement at PCs and LASERs does not change the fact that they are awesome and stem from the study of quantum mechanics. A larger flaw is his matter-of-fact presentation of certain controversial theories as "yeah, that's the way it is; don't bother investigating further." John Gribbin graduated with his bachelor's degree in physics from the University of Sussex in 1966. Gribbin then earned his master of science (M.Sc.) degree in astronomy in 1967, also from the Univ. of Sussex, and he earned his Ph.D. in astrophysics from the University of Cambridge (1971). You are the only contemporary physicist, besides Laue, who sees that one cannot get around the assumption of reality, if only one is honest. Most of them simply do not see what sort of risky game they are playing with reality—reality as something independent of what is experimentally established. Their interpretation is, however, refuted most elegantly by your system of radioactive atom + amplifier + charge of gunpowder + cat in a box, in which the psi-function of the system contains both the cat alive and blown to bits. Nobody really doubts that the presence or absence of the cat is something independent of the act of observation.

I was reading alone in my study in the night, when there was a movement behind me. "Miaow," someone said. 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. The third part probes some of the deeper mysteries, possibilities and paradoxes of quantum mechanics. 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

I really resented being called an idiot, but did not want to aggravate this temperamental feline with the sharp claws. "What's that?" Schrödinger's story is a critique of the idea of quantum blurriness. But, some pop sci author read the story, thought it was meant to be interpreted literally ("Large felines can exhibit quantum blurriness") and countless others retell the explanation, not the story. It's like hearing that the Emperor's New Clothes is about the eye-opening power of fashion without reading the tale yourself. Oh, you are an idiot!" The cat laughed. "Don't you see it was an experiment to question the Copenhagen Interpretation?" In the last section the signature of a century-long debate, logic hurling, a plethora of thought experiments, and lots of recipes from the quantum cookbook grace the book. Without pulling any mathematical punches the author neatly explains lasers, masers, semiconductors, quantum computers, entanglement, and things of not-so-distant or far away future. I scanned my bookshelves. Suddenly illumination lit up on me. "Bulgakov! The Master and Margarita!" I exclaimed.Both events happened, but we don't know which alternate universe we're in. Maybe every possible outcome creates a new timeline. (I flip a coin and put it under my hand. Are we in a spooky quantum state?) There rested mainly two theoretical swords or guns in the valley in the early upbringing of quantum.
