power or nuclear bombs, no lasers, no TV, no computers, no science of molecular biology, no understanding of DNA, no genetic engineering at all John Gribbin tells the complete story of quantum mechanics, a truth far stranger than any fiction He takes In Search PDF/EPUB ² us step by step into an ever bizarre and fascinating place requiring only that we approach it with an open mind He introduces the scientists who developed quantum theory He investigates the atom, radiation, time travel, the birth of the universe, superconductors and life itself And in a world full of its own delights, mysteries and surprises, he searches for Schr dinger s Cat a search for quantum reality as he brings every reader to a clear Search of Schrödinger's PDF/EPUB é understanding of the most important area of scientific study today quantum physics. um i read this book i didn t read this book i read this book and didn t read this book i read this book in one universe and didn t in another this book didn t exist until i read it gribbin s great because he won t dumb down but genuinely wants you to understand this stuff and b c he believes in time travel yay this book is f n awesome.i read it in highschool and then again in college because while you re reading it it s like having a really good teacher who holds your attention and makes you understand unusual ideas but as soon as you finish and put it down you re like wait, how does that work again so for me at least, i have to be reading it to maintain that state of enlightenment maybe after a certain number of reads it will stick because i am not naturally good at this sort of subject this book is f n awesome.i read it in highschool and then again in college because while you re reading it it s like having a really good

to maintain that state of enlightenment maybe after a certain number of reads it will stick because i am not naturally good at this sort of subject 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.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.this book also led me to read other books about heisenberg and einstein.it definitely make you think yeah, it definitely makes you think I was reading alone in my study in the night, when there was a movement behind me Miaow, someone said.I looked behind me A tabby was sitting, contentedly washing herself Hey Where did you come from I asked You can see me She beamed Whew That s a load off my mind I thought I might be dead I found this rather strange How can you talk to me if you are dead Well, I meant dead in this universe She went on with her toilet.I was a bit uneasy Needless to say, talking cats appeari I was reading alone in my study in the night, when there was a movement behind me Miaow, someone said.I looked behind me A tabby was sitting, contentedly washing herself Hey Where did you come from I asked You can see me She beamed Whew That s a load off my mind I thought I might be dead I found this rather strange How can you talk to me if you are dead Well, I meant dead in this universe She went on with her toilet.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.She winked Guess I scanned my bookshelves Suddenly illumination lit up on me Bulgakov The Master and Margarita I exclaimed.The tabby s look was contemptuous Oh come on Do I look like a demon Okay I tried again The Cheshire Cat My companion looked pained I am much better than that grinning idiot from a stupid children s book, I ll have you know Okay, I m stumped I threw up my hands You tell me The tabby got up, swished her tail, arched her back and generally preened herself I am the one and only Schrodinger s Cat She bowed her head, as though expecting applause 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 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 Oh Now I remember I said I did only vaguely but I wanted to save myself from getting scratched, which I seemed to be in imminent danger of Wasn t he the famous quantum scientist Yes He practically defined quantum reality He left me in a box with a poison vial, a radioactive isotope, and a Geiger counter If the counter detected any radioactivity, the poison vial would break and I would die If it didn t, the vial would stay as it is I would live She beamed 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 Oh, you are an idiot The cat laughed Don t you see it was an experiment to question the Copenhagen Interpretation I really resented being called an idiot, but did not want to aggravate this temperamental feline with the sharp claws What s that Well, it was all these scientists talking about wave particle duality how subatomic particles behaved both like a wave and a particle, and changed into one or the other only upon observation Schrodinger was dead against it So he created me in the box and I am both dead and alive until someone observes me at what point, either the vial breaks or it doesn t, I either die or live She said all this in one breath That s stupid You can t be dead and alive at the same time In fact, you are very much alive now I was indignant Precisely The tabby washed her paw I am either dead or alive The same way with subatomic entities they are either waves or particles Or they are something else altogether which our puny imaginations can comprehend Her vocabulary was getting richer Well, you are alive now I reiterated Hmm Yes My feline friend did not seem too sure of herself I guess so You guess so I was flabbergasted My dear kitty, can t you feel yourself, hale and hearty I can She looked up at the ceiling But John Gribbin says that in a parallel universe, I am dead Okay, so to best describe this book, I need to first describe Schrodingers cat Keep in mind that this an illustration of what Schrodinger saw as the problem with the Copenhagen idea of Quantum superposition Imagine a box with a cat inside A vial of a deadly chemical which will instantly kill the cat is placed inside with the cat, sealed so the feline is safe A hammer is set up with a rig to smash the vial but only if the following occurs A small amount of radioactive material is inside a ge Okay, so to best

box with a cat inside A vial of a deadly chemical which will instantly kill the cat is placed inside with the cat, sealed so the feline is safe A hammer is set up with a rig to smash the vial but only if the following occurs A small amount of radioactive material is inside a geiger counter If an atom inside decays, it triggers the hammer and the cat dies If not the cat lives The probability of the atom breaking down is equal to the probability of it remaining intact According to the Copenhagen model, this would mean that the cat is both alive and dead inside the box until the atom is observed It was a thought experiment, produced to ask when does a Quantum model cease to be a mixture and become one thing or another If you were able to follow me on that, check this book out Otherwise, this kind of thing may not be for you I loved the information but the writing was a bit rough That is to be expected of a science book Gribbin seems to have a sound understanding of quantum mechanics, and his writing is rather well crafted, but sometimes I think he d rather have been a historian than a physicist The first half of the book is mostly intricate historical accounts of the key players of the story of quantum mechanics over the last century Gribbin reveals the concepts very slowly, which might not be a bad thing, so this may seem a bit tedious at first However, by the end, the concepts

concepts, I m not sure if I m meshing too well with the opinions on parallel universes that Gribbin states at the end, and the illustrations are badly placed, only moderately insightful, and actually contradict the text in places However, I enjoyed this immensely and highly recommend it to anyone looking for a low to no math introduction to quantum mechanics 4 stars for science nerds, 3 stars for

in merely coming up with ways to prove ideas.A pretty dense book if you aren t a nerd I am so, lucky me Physics was one subject i was never good at during High school not that i was great at any of the other subjects though but Physics was a nightmare There were concepts which were totally ambiguous to me and went way above my head This book not only clarified some of them but also instilled in

Physics was one subject i was never good at during High school not that i was great at any of the other subjects though but Physics was a nightmare There were concepts which were totally ambiguous to me and went way above my head This book not only clarified some of them but also instilled in me a deep interest in Physics In this book, John Gribbin gives a fabulous peek into the magical realm of quantum physics He begins with an explanation on the very basic unit of life the atom and the various evolving attempts by scientists to give an accurate description of the structure of an atom Including the various experiments leading to the discovery of protons, neutrons and electrons He then explains the Planck s black body radiation and the famous two slit experiment whose observations threw the entire scientific community into a state of utter ambiguity and disarray about the nature of electrons Someexperiments later they discover the photon and the dual nature particle and wave nature of light and particles like electrons This is followed by discoveries by Pauli the Pauli exclusion principle , Heisenberg, Born and Schrondinger which strengthen the theory of quantum mechanics A very interesting part of the book is on time travel which according to the author is possible atleast theoretically though it might have a lot of practical hurdles He believes that parallel worlds do exist but not the way in which we imagine in most of the sci fiction books where we can hop between the alternate universes but all the alternate universes according to quantum theory branch out based on the choices that the observer encounters He also writes about the two different theories explaining the way things work in this universe The Copenhagen interpretation where there are numerous possibilities of something happening but there is only one reality in one world and the rest are just virtual ghostly worlds which all collapse into one result when the observer actually observes the system The many worlds interpretation contradicts the Copenhagen interpretation in the sense it assumes all the possibilities to be equally real and exist in their own worlds with their own observers us being one of them All in all the entire quantum mechanics lies on the observer who observes the system What happens when the observer is not looking is something that is not explained by the quantum theory and can only be speculated Finally, the search for Schrodinger s cat ends by the author using the many worlds theory to testify the fact that the cat is in reality both dead and alive in two separate, mutually exclusive worlds but not either dead or alive When the observer looks into the box, he forces one outcome , which is the cat is either dead or alive and the other possibility still exists in its own world with its own observer which is as real as our universe A very interesting theory but this is just the author s personal views i guess The author in the end also touches upon the theory of supersymmetry which is the latest field under study within the quantum community and deals with unifying matter particles like electrons,protons, quarks etc and force the bosons like photons etc The entire book has been an amazing ride through the mindbogglingly unbelievable world of the sub atomic particles and i cant say it better than Neils Bohr Anyone who is not shocked by quantum theory has not fully understood it I m reading this again after a few years so that when I give it to my girlfriend to read and EXPAND HER MIND I will be able to help guide her through it So far, it has been a great intro to quantum mechanics It s supposed to be for the layman, and it appears fairly basic, but I have some background, so it s hard for me to judge that.EDIT 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, m I m reading this again after a few years so that when I

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 As for Gribbin, he has trouble pacing and keeping his writing consistent He ll meander aimlessly and point out important subjects he ll describe later Worst, his level of detail and required scientific background is horribly inconsistent From a relatively simple, easy to follow, and well suited for the layman explanation of the structure of the atom to his absurdly obtuse description of the most important experiment to confirm the predictions of quantum mechanics, he leaves the reader fighting to piece together his point 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 This book does have a lot of good information and does explain some aspects of quantum mechanics very well for someone with little experience, but he kind of unravels at the end I wish I d written A Quantum Theory of Mitt Romney In particular, Figure 2 the best Feynman diagram joke I ve ever seen I wish I d written A Quantum Theory of Mitt Romney In particular, Figure 2 the best Feynman diagram joke I ve ever seen A very well explained journey of quantum science John clearly tells us why there was even a need for these theories and how, after many weird observations, the concept of Schrodinger s Cat and other theories emerged I am neither a mathematician nor a physicist Still, the way he wrote, it s not much difficult for a guy like me to comprehend the book.
