This iconoclastic book proposes that superconductivity is
misunderstood in contemporary science and that this hampers
scientific and technological development. Superconductivity is the
ability of some metals to carry electric current without resistance
at very low temperatures. Properly understanding superconductivity
would facilitate finding materials that superconduct at room
temperature, providing great benefits to society.The conventional
BCS theory of superconductivity, developed in 1957 and awarded the
Nobel Prize in 1972, is generally believed to fully explain the
lower temperature 'conventional superconductors' but not the more
recently discovered 'high temperature superconductors', for which
the charge carriers are positive Holes rather than negative
electrons. Instead, this book proposes the holistic view that Holes
are responsible for superconductivity in all materials. It explains
in simple terms how the most fundamental property of all
superconductors, that they expel H-fields (the Meissner effect),
can be understood with Hole carriers and cannot be explained by
BCS. It describes the historical development of the conventional
theory and why it went astray, and credits pre-BCS researchers for
important insights that were forgotten after BCS but are in fact
relevant for the proper understanding of superconductivity.The
book's author, Jorge E Hirsch, is a renowned expert in the field of
condensed matter physics who has published over 250 articles on the
subject. He has developed the theory of 'Hole superconductivity',
the focus of this book, over the last 30 years. He is also the
inventor of the H-index, a bibliometric measure of scientific
impact which, he admits in this book, fails to identify high
scientific achievement in the field of superconductivity.
