"A survey of some of the most important ideas about the always fluctuating quantum vacuum along with a description, based on fundamental vacuum processes, of the physical concepts of quantum electrodynamics." --SCI TECHBOOK NEWS, 1994"The Quantum Vacuum [is] an informative and very readable introduction to quantum electrodynamics. It is a remarkable idea that a book on this topic should be a 'page turner but I found it difficult to put down....I have not come across a better introduction to this subject than Milonnis text. All serious students of quantum theory will benefit from reading it and I have already recommended it to my students. I am looking forward to finishing working through the later chapters once I get the book back from the aforementioned students!" --JOURNAL OF MODERN OPTICS (1994, vol. 41, no. 5, 1051-1052)
