This volume gives an up-to-date, systematic account of the microscopic theory of Bose-condensed fluids developed since the late 1950s. In contrast to the usual phenomenological discussions of superfluid 4He, the present treatment is built on the pivotal role of the Bose broken symmetry and a Bose condensate. The many-body formalism is developed, with emphasis on the one- and two-particle Green's functions and their relation to the density response function. These are all coupled together by the Bose broken symmetry, which provides the basis for understanding the elementary excitations and response functions in the hydrodynamic and collisionless regions. It also explains the difference between excitations in the superfluid and normal phases. Chapter 4 gives the first critical assessment of the experimental evidence for a Bose condensate in liquid 4He, based on high-momentum neutron scattering data.

As an international speaker with more than a dozen years of experience speaking to all kinds of audiences, I can say this is a truly useful collection of tips that can help any speaker rise to the next level. I've read many books for speakers, and this is the one I'd use right before I go on stage or as I fly to my next engagement to remind me of the basics and to get a good, positive outlook thanks to its bite-sized chunks of wisdom.

Secrets of a Unique & Sexy Speaker sets out the rules of speaking in clear, concise, and easy-to-follow steps that take the mystery and fear out of public speaking. This is an indispensable guide for anyone who wants to, or has to, stand before an audience to deliver a message. Rona Arato, author of The Last Train, a Holocaust Story
Lucky me! I read Secrets of a Unique & Sexy Speaker before two public appearances, one in front of a hundred or so businesspeople and the other before a board of eighteen. I chose several Speaking Tips to practice and test drive. While much of the book might have you nod in recognition, if you re aware of your own ticks and have received feedback about your speaking, you will as I did benefit enormously from consistently applying these techniques to help you improve. As Marion Claire points out, speaking is a mental as well as physical sport that requires preparation to achieve greater freedom of expression. Thank you, Marion, for your thorough, practical and encouraging guidance. Agnes Mura, MA MCC, global leadership coach, www.AMIcoaches.com
