I bought this book because the Amazon website told me to. Well actually I had just finished Manjit Kumar's "Quantum" and thoroughly enjoyed its exploration of the quantum world and was ready for more and the Amazon website told me "People who liked this also bought..." ! I am delighted with the recommendation! This excellent book more than met my expectations and I found it thoroughly enjoyable. Having already read "Quantum" some of the concepts were by now familiar to me so I was able to read it with a better understanding. Mind you, after finishing both books, I now know that I will never really understand particle physics, and in fact have come to an acceptance of this, but it was nonetheless a fantastic journey! I comment you to do the same!
