The phenomenon that Einstein thought too spooky and strange to be true

What is entanglement? It's a connection between quantum particles, the building blocks of the universe. Once two particles are entangled, a change to one of them is reflected---instantly---in the other, be they in the same lab or light-years apart. So counterintuitive is this phenomenon and its implicati

I am really undecided about this book, which I really wanted to like.
To be honest, while there are some sections that are done brilliantly, there are unfortunately some examples/experiments that are not described clearly and where the hand-waving is really a bit too much. I did not particularly like the section on relativity either: I can easily remember several other books where relativity is explained still in a concise but in a much more clear manner.
In summary, I found that the book is unev

Anton Chekhov once said that if you say in the first chapter of your book that there is a rifle hanging on the wall, in the second or third chapter it absolutely must go off. In other words, if the gun is not going to be fired, it shouldn't be hanging prominently on the wall.

With that in mind, I looked forward to the author’s discussion of how quantum entanglement could be seen as evidence of an invisible space deity, and was

I thought the book was pretty good and helped to give me a ok understanding of quantum entanglement which is till a little hard to understand. I also liked it a lot because it talked about Einstien and it showed how he didn't like the concept of it and tried to prove it wrong on several ocasions but only strengthend the theory

As a non-physicist who in intrigued by this kind of book, I was very pleased. Although this book is now somewhat outdated, Clegg gives the most understandable explanation I've read so far about the "spookiness" of quantum entanglemant.

Great stuff. Exactly what I was looking for. For anyone interested in QE, a good starter book.

The Clegg book talks about an amazing aspect of quantum theory, which is that when two particles are created that are linked, or entangled, in spin or some other property, and then separated, and then when the spin of one particle is observed the spin of the other is automatically determined no matter how far away it is. This seems to violate the notion of local causality (not to mention the speed of light). The concept was dismissed by most physicists from the start (even Richard Feynman though ...more

Quantum Mechanics eerie phenomenon (one of the many) - quantum entanglement - is being described in this book that is clearly written for the non-hardcore-scientist (eg. me). That being said the reader can't just sit back and enjoy the ride, some thinking is necessary and since the topic is part of Quantum Mechanics one needs to be prepared to have ones brain twisted into a pretzel.

The chapters describe possible uses for the entanglement effect and why it is so fiendishly difficult to make it w

I'm constantly impressed by Brian Clegg's ability capture both the science and the fact of tricky phenomenon. It's not pedantic but necessary to spend fifty pages on the differences between a model and observed fact when talking about something like the quantum behavior of photons going through polarizing filters. I recall having seen the Bell Inequality and eventual Bell Experiments before but the treatment here is phenomenal.

The digression regarding the history of cryptography was largely unne

If you know anything about quantum entanglement already you will not learning anything new from this book....well that may be a bit harsh. There might be twenty to thirty pages of information on entanglement itself the rest is a history of other topics in which entanglement could be exploited. It for some reason includes a whole chapter (out of 8) about the possibility of sending information instantaneously when he has already proved that no information can transfered through entangled particles ...more
I was not terribly impressed. This book further solidified my belief that the Higgs Boson does not exit, nor does dark matter, but that these are constructs to fill in the gaps in theories where observations cannot be explained. Some areas were truly ridiculous to even read, such as teleportation. Action at a distance? Show me.

Good read. Focuses more on potential applications than theory (since we don't really understand the whys and how's of quantum mechanics anyway), but an interesting survey of what is and is not possible.

Offers very little scientific explanation and a lot of extrapolation and tangential trivia. Good if you like that sort of thing I suppose, but for me it was rather frustrating.

I'm reading this based on a reference to entanglement by Ray Kurzweil.
Interesting concept, but poorly written. How this author manages to make the idea of possible teleportation boring is beyond me, but he does! LOL

This was good, but, every time I read about Entanglement I think I understand it less every time ~

Interesting account of the physics phenomena of entanglement and how it can , as well as could, affect our lives.

This book is heavy on the academics, but very interesting and engaging. Worth a look.
