Quantum Reality: Beyond the New Physics (1987)

ספר מרתק על הניסיונות השונים, שמונה במספרף לתאר את​ המציאות שמאחורי תורת הקוונטים. החל מגרסת קופנהאגן​ (אין מציאות) דרך אינשטיין והריאליסטים (מציאות רגי​לה, חסרים משתנים) וכלה בעולמות מקבילים. ​
דגש רב (מדי?) על משפט בל שטוען לקיום קשרים מהירים​
קריאת הספר רק הגבירה את הרגשתי עד כמה אינני יודע.​ ( )

This is a great book by Nick Herbert. This is a book that deals with the interpretation of Quantum Physics. But its importance is that it deals not with a 'spiritual' or 'mystical' understanding of quantum physics but with how scientists and physicists themselves interpret quantum physics. It is a book of pure science and there is no quantum mysticism involved here.

Nick Lembert discusses basically eight different interpretations of quantum physics. These include the Copenhagen interpretation, Feynman's interpretation, the 'multiple worlds' interpretation, etc. All these interpretations are the work of the greatest physicists in quantum physics. These are the ways in which the scientists understand how physics work. They are not important in getting the results of quantum dynamics, the maths of quantum physics works independently of which interpretation we may choose to believe.

And this is where Herbert shows the craziness of quantum physics: although all these interpretations are radically different from each other, they can all explain quantum physics equally well. Neither we, the non-physicists, nor the greatest physicists in the world, really know what actually is going on in this strange little world, whether the particles are behaving according to the Copehnhagen interpretation, the multiple world explanation, etc. Herbert handles this very well, we get a sense of why Feynman said, 'just shut up and calculate'. Scientists dont understand the basic reality of quantum physics either!

Another very useful thing I took away from the book was the explanation of the wave equations of Quantum Physics. Herbert does a fine job of showing what exactly waves are and how physics describes the particles as waves and what this means. This again shows up the mysteriousness of Quantum Physics in another way.

All in all, I would call this a very important book to understand the general principles of quantum physics, one that is vital because it sets out the different interpretations in a very clear and comprehensible manner. ( )

Great exposition of quantum mechanics. The most memorable for me was his telling of all the different types of waveshapes that can be considered as representations. He used the analogy of a synthesizer to great effect. ( )

A clear yet rather extensive introduction to the relationship between Quantum theory and a definition of reality. Though Herbert's book can be used as an introduction to the core of Quantum theory, the book is intended to explore the relationship between the theory and what can be asserted about the very nature of reality. This is even better if you have already started with one of the numerous book meant to describe the theory only.
Four stars only because the book is getting a bit old :) ( )
