Also it was interesting finally to find out what stands behind the overused metaphor of Schrodinger's cat:-) A cat is in a box with a radioactive source and a poison that will be released when the source (unpredictably) emits radiation. According to quantum mechanics, the cat is simultaneously both dead and alive until the box is opened and the cat observed. After we understand the original argument, we can debate whether the criticism makes sense. If particles appear to be blurry at a quantum level, then perhaps:

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?) 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.Because it's absurd for a macroscopic object to be "blurred" (right?), the subatomic particle can't truly be blurred 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. 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?" 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.

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. Another theory, the MWI or Many World Interpretation is not big on uncertainty but hurls another outrageous curveball. If you asked an intelligent well-read but non-scientific person to summarise the most important contributions of science to our present lives and suggest the possible benefits or hazards of scientific progress in the near future, you’d surely be given a list that included: This work lays bare the way scientists work together, solve problems, follow threads, and the implications it has for the world at large is fascinating. The first two parts of the book explore the discussions, and scientific developments as quantum theories began to emerge from classical Newtonian approaches.

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. For me now it has become apparent that time travel, teleportation, antimatter and multiple realities are well established phenomena of physics, not of unhealthy imagination. Oh! The best thing about this theory is (to many) that God is not inclined here to play addictive games like dice. 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 story seems to be that Quantum Mechanics is so weird, a cat can be both alive and dead until we look!

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. I really resented being called an idiot, but did not want to aggravate this temperamental feline with the sharp claws. "What's that?" Wikipedia Article on Schrödinger's Cat - Wikipedia is difficult to learn things from, but has great lists of referencesI 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. Your observation (at a subatomic level) is the modicum of truth-seeking, like a heavy-bottomed flashlight in the dark or that old hand-held camera, that will ensure a freeze frame of surety within this slithy, gyrating confederacy of indeterminacy. See, I don't know anything about QM. But I've read enough (2 paragraphs of his paper) to realize the majority of QM explanations miss Schrödinger's point. No. I am not messing around. This can be mathematically established. Hugh Everett did this in the 1950s. 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.

Philosophically, the issue reminds me of how we think about infinitely small quantities. Do infinitesimals exist?A subtle problem with this book seemed to me it's a little dated. Still, this is an enlightening launch pad for adventuring in the quantized unknown. 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 and I would live." She beamed. An Elizabethan male dramatist (or female?), unbeknownst to himself succinctly put this --"To be or not to be".
