The later parts of the book look at the more recent work in low temperature physics, in particular the problems of the interaction of superconductivity and magnetic fields, and how solving these was necessary for the commercial use of superconductors. History of technology is always a difficult topic to write about, and it is nearly 30 years since the book was published, so it's no longer recent technology. I felt that the book would have done better to stick to the story of attempts to achieve ever lower temperature. On the other hand Mendelsson knew what he was writing about - he's recognised as an expert in this field of study - and many people might like to read what such a prominent researcher has written about his subject."; include "amazinf.php"; ?>
